Saw Chain

How do I measure the length of my chain?

Count the number of drive links on your saw chain in order to determine its length. A drive link is the saw chain component that guides the chain through the guide bar rails and around the sprocket. It is very important that the number of drive links are a match for the guide bar you are using since your chainsaw won’t function properly otherwise.

Common examples of drive length count are 70 for "D" or "72" chain and 56 for "S" or "91" chain.

How tight should I tension my chain?

A snap test should be performed. Grasp the chain along the bottom of the bar, pull down, and let go. The chain should snap back to its original position, solidly contacting the bottom of the bar rail. For general instructions on how to tension your chain, check out our chain instructional guide and video.

How do I tighten a chainsaw chain?

How do I sharpen my chain?

Please watch our chain sharpening video.

How long should the drive sprocket on my saw last?

It's important not to run a new chain on a badly worn drive sprocket. Replace drive sprocket systems after every two chains, or sooner.

How do I know when my chain is dull, and when should I sharpen it?

Keep in mind that a sharp chain will cut large-size chips. A chain that is dull or has abrasive damage will create sawdust. It's time to sharpen when you have to push on the saw, or the saw is no longer self-feeding.

What is chain pitch?

Chain pitch is the size of the chain, and is defined as the distance between any three consecutive rivets divided by two. Oregon chain is made in several pitches - 1/4" is the smallest, 3/8" is the most popular, 3/4” is the largest. Pitch is important because the drive sprocket must be the same pitch as the chain, and if applicable, the bar nose sprocket. The easiest way to determine the pitch of your chain is to look at the number stamped on the drive link.

What is Chain Gauge?

Chain Gauge is the Drive Link's thickness where it fits into the bar groove. The gauge of the chain and the gauge of the bar must match. Oregon has several gauges for chainsaws - such as, .043”, .050", .058” and .063". Normal wear can make it difficult to accurately measure chain gauge on a worn chain. Always order by the number stamped on the drive link of your old chain to assure correct gauge.

How often and what type of lubrication should I use on my saw?

Keep your saw's chain-oiling system filled with clean bar-and-chain oil. Never put used oil or old motor oil in your saw or on your chain. Be sure your chain, bar, and sprocket are always receiving oil from the saw during operation. Fill your oil reservoir each time you fill your gas tank.

How do I sharpen my chain?

Please watch our chain sharpening video.

How much slack should be in a chainsaw chain?

See chain tensioning instructional guide and video for additional information.

How do I know when my chain is dull, and when should I sharpen it?

It's time to sharpen when you have to push on the saw, or the saw is no longer self-feeding. Also, the waste material from your saw is an important indicator of your saw’s sharpness. While a sharp chain will cut large-size chips, a chain that is dull or has abrasive damage will create sawdust.

A good rule of thumb is to sharpen your chain every time you refill gas.

Chain Lubrication

How often should I lubricate my chainsaw?

Fill your oil reservoir each time you fill your chainsaw’s gas tank. Make sure that your saw chain, guide bar, and sprocket are always receiving oil from the saw during operation.

What type of lubrication should I use on my saw?

Keep your saw's chain-oiling system filled with clean bar and chain oil. Our bar and chain oil is specifically compounded to provide extra high tackiness and prevent "throw off" even under adverse weather conditions.

Never put used oil or old motor oil in your saw or on your chain. Used motor oil contains metal shavings that reduces the life of your bar and chain. Lubricating your bar and chain with used motor oil also voids your warranty.

Guide Bar

How do I know what size guide bar I have?

Guide bars are measured by the actual cutting length when mounted on a saw.

The cutting length is the distance from the front of the saw to the tip of the guide bar, rounded to the nearest inch. For example, the overall length of a 16-inch bar may be about 20 inches.

How do I clean my chainsaw guide bar?

In our guide bar maintenance video, a forestry expert from the Oregon Technical Services department demonstrates correct way to clean your chainsaw bar.

Protective Gear

How long should chainsaw chaps be?

Chaps should be long enough to cover the tops of your boots. To know how long your chaps should be, measure from your waist (just below the belt where the chaps will sit) to the beginning of your foot. This length will provide full coverage and protection.

Precise measurement is an important step in ensuring that you get chaps that are the right size. If chaps are too short, your legs could be exposed. Chaps that are too long, however, are also unsafe since they could cause you to trip.

How do I choose chainsaw chaps?

Check to see that the chainsaw chaps comply with safety standards issued by international certifying bodies. These products have been tested by professionals to ensure that the chaps really do provide protection from contact with a chainsaw. Chaps are rated by OSHA and ASTM (the American Society for Testing and Materials) and ANSI (American National Standards Institute) and receive certification from UL (Underwriters Laboratories). In order for chaps to have an OSHA rating, they must be made out of cut-resistant material and provide coverage from the beginning of the thigh to the top of the boot on each leg. ASTM has two standards for chaps: a standard for the performance of chaps (ASTM F1897-14) and a standard for testing chaps (ASTM F1414). Chainsaw chaps with the UL label meet ASTM’s performance and testing standards.

When evaluating the material of chainsaw chaps, research the number of layers as well as how thick they are. Each chap has a different number of layers – the more layers the better. Oregon’s Apron Chaps and Full-Wrap Chaps are made from 8 layers of fabric. When evaluating the thickness of chap layers for the term denier – this measurement denotes how thick chaps are. Pay attention to sizing in order to maximize your protection from injury. The length given for a pair of chaps is the overall length – not the length of the inseam. For more information on how to find the right size see the question “How long should chainsaw chaps be?” below. For even more information about chainsaw chaps, read our chainsaw protective gear instructional guide.

How do you wash chainsaw chaps?

Wash your chainsaw chaps by hand. Then, hang them to try in order to protect the material structure.

How do chainsaw chaps work?

Chain saw chaps are not cut proof but what they do is prevent the moving chain from cutting your leg; the kevlar material in the chaps tangles up in the chain providing a few seconds to move your chainsaw away from you or shut it off completely. If you should stumble and accidentally trip while walking - you will be protected.

Sprockets

How long should the drive sprocket on my saw last?

Replace drive sprocket systems after every two chains, or sooner. It's important not to run a new chain on a badly worn drive sprocket.

What is the drive sprocket?

The sprocket and the clutch drum are connected to the saw motor. The sprocket is designed to drive the proper-pitched chain around the guide bar.

Safety

What is ANSI?

Certain provisions of the safety standard known as "ANSI (American National Standards Institute) B175.1 - Gasoline powered Chainsaws - Safety Requirements" contain requirements designed to reduce the risk of injury from chainsaws sold in the United States. The following information should be used as a guide for the selection of appropriate replacement chains in order to maintain compliance with the ANSI B175.1 standard (United States only).

The ANSI standard B175.1 divides all chainsaw power heads into two groups:

Under 3.8 cubic-inch (62cc) engine displacement, the chainsaw MUST meet the low kickback provisions of the standard.
3.8 cubic inch (62cc) and larger, the chainsaw MAY OR MAY NOT meet low kickback provisions of the standard.

Any chainsaw that does not qualify as a low kickback cutting system will bear a warning such as: “WARNING – This chainsaw is capable of severe kickback that could result in serious injury to the user. Do not operate this chainsaw unless you have extraordinary cutting needs and experience and specialized training for dealing with kickback. Chainsaws with significantly reduced kickback potential are available.”

Be sure to read the labels on a chainsaw before purchasing one.

Lawn and Landscape

When should I replace my lawn mower belt?

Replace your lawn mower belt if it shows signs of wear including fraying, shredding, glazing (shine and brittleness from melted rubber) or shredding.

How do I measure a lawn mower belt?

You can measure your lawn mower belt with a cloth measuring tape – the kind you would use for sewing. Belts are measured in inches. All mower belts should be measured diagonally – from corner to corner.

How do I tighten a lawn mower belt?

There is no way to adjust mower belt tension. Tension is maintained by spring loaded idler pulleys.

Edger Blades

Are edger blades reverse threaded?

Edger Blades are not threaded.

How do you sharpen edger blades?

You should not sharpen edger blades. Since they are in constant contact with dirt, cement edges and curbs edger blades dull very quickly. If your edger blade appears dull, you should replace the blade with a new one.

PTO Clutches

What is an electric PTO clutch?

An electric PTO clutch is a device attached to the motor that transfers power to the mowing deck.

How do I clean a PTO clutch?

Clean your PTO clutch with compressed air. All service and repair facilities have an air compressor capable of blowing dust and debris from the PTO assembly. Canned air, like the kind you use for your computer keyword, does not have enough force to properly remove debris.

Mower Blade Sharpening and Balancing

When should I replace my mower blades?

Mower blades should be replaced when they are damaged or have 1-inch of the original width removed.

What tool do you use to sharpen mower blades?

The best way to sharpen a mower blade is with a dedicated blade grinder. A blade grinder is the best tool to use, because it can maintain consistent sharpening angles. See our Lawn Mower Blade Sharpening Instructional Guide for more information.

How often should I sharpen my mower blades?

Homeowners should sharpen their mower blades at least once a year. Commercial landscapers should sharpen their blades more often than homeowners.

Why should I balance my mower blades?

Balancing mower blades prevents harmful vibration and wear from damaging your mower.

How sharp should mower blades be?

Your blades should be aggressively sharp but without a razor edge. The edge of the blade should have a small radius.

Mulching Lawn Mower Blades

What are Gator® Mower Blades?

Gator® Mower Blades are 3-in-1 mower blades that mulch, bag and discharge grass clippings.

Are mulching blades different from lawnmower blades?

Yes, they have a higher "lift" than standard mower blades and an extended cutting edge. When we see that the lift is higher, this refers to the fact that the lift area of the blade is higher to better lift the grass.

Which way does a mulching blade go on?

The fin of the mulcher blade should be pointed up.

What are mulching blades used for?

Mulching blades are used to finely chop grass clippings and return them to the soil where they act as a natural fertilizer.

What is a mulching blade?

A mulching blade is designed to re-cut grass clippings several times before they are discharged.

Lawn Mower Oil Filters

How do I change a lawn mower oil filter?

Unscrew old filter
Lubricate seal on new filter
Screw onto engine block.

How often should I change the lawn mower oil filter?

Change the oil filter every time you change the oil on your lawn mower. See your mower’s owner’s manual for intervals.

Lawn Mower Spark Plugs

What does the lawn mower spark plug do?

The spark plug ignites the fuel in the cylinder generating the power stroke in the motor.

What causes lawn mower spark plugs to foul?

Common causes include worn engine parts, dirty air filter, old fuel and improperly mixed fuel.

Why is the lawn mower spark plug wet?

Typically a wet spark plug can be caused by a clogged air filter, weak ignition, poor quality fuel.

How does the lawn mower spark plug work?

The spark plug receives a charge of voltage from the ignition system, sparks at the electrode and ignites the fuel in the combustion chamber.

How long do mower spark plugs last?

Spark plug lifespan depends on engine and fuel conditions. Your spark plugs should be replaced at least once a year.

Are all lawn mower spark plugs the same?

No. All lawn mower spark plugs are not the same. Spark plugs are engine specific. There are different sizes and heat ranges (voltage requirements).

Are lawn mower spark plugs universal?

Lawn mower spark plugs are not universal in fit. They are specific to individual make and models.

Lawn Mower Tires

What do lawn mower tire numbers mean?

For Oregon lawn and garden tires the numbers are overall diameter, section width, and rim diameter (in that order). Size designations consist of 2 or three numbers separated by an ‘x’, dash or slash mark.

For example, if an Oregon tire has the numbers “16x650-8”, it has an overall diameter of 16”, a section width of 6 ½” and a rim diameter of 8”.

Where do I find the sizing information for my lawn mower tire?

Dimensions are usually listed on sidewall of the tire.

When should I replace my lawn mower tires?

When they leak or become worn out or weather checked. The term weather-checking refers to when the tire’s side wall becomes cracked as a result of exposure to the sun and rain.

How do you inflate a lawn mower tire?

Use an air compressor or tire pump (depending on tire size). Do not overinflate. See specs on the side of tire.

How do you measure lawn mower tires?

Dimensions are usually listed on sidewall of tire.

How are lawn mower tires sized?

Log Splitters

What are log splitters?

A log splitter is a piece of machinery that is used to split large pieces of wood into smaller pieces of firewood. Log splitters can be used by homeowners as well as in commercial settings.

Why is my log splitter moving slow?

The hydraulic system may be low on hydraulic oil, or the pump may be malfunctioning. Please to the engine’s owner’s manual for specific trouble-shooting instructions.

Why won't my log splitter start?

The engine fuel tank may be empty, or the engine may be flooded. To find the specific cause, consult the troubleshooting section of the manual that came with your log splitter’s engine.

How does a log splitter work?

The splitter has a plunger to force the wood into a moving or stationary splitting wedge. The plunger continues to move the wood piece through the wedge or the wedge through the wood to separate the piece into two parts.

How do I use a log splitter?

Load the wood to be split into the splitter between the splitting wedge and the base foot. Making sure your hands are removed from the wood, activate the splitter plunger or wedge to push the wood into the wedge or wedge into the wood. When the wood is separated into two parts, reverse the plunger or wedge and remove the wood pieces from the splitter.

If you are looking instructions on how to use a specific Oregon Log Splitter, you can find log splitter manuals via the Oregon Log Splitters section of the Product Manuals and Technical Information page.

How do you calculate log splitter tonnage?

The basic engineering formula for force from a hydraulic cylinder is F=P(A) where Force (F) in lbs is equal to pressure (P) in lb/in² multiplied by area of the cylinder head (A) in in². This renders a result in lbs which needs to be converted to US tons by the factor of 1 ton/2000 lbs.

What oil do I need for my log splitter?

AW46 Hydraulic oil is recommended. Automatic transmission fluid can be substituted and should be used instead of hydraulic oil when temperatures are below 32 degrees F.

What makes a log splitter fast?

The speed of the splitter is proportional to the flow rate of the hydraulic fluid into and out of the hydraulic cylinder.

Battery Packs & Chargers

CS300 Cordless Chainsaw

When using the CS300 chainsaw, how long does the battery last?

The 4.0 Ah Battery Pack will last up to 400 cuts per charge in 2 to 3 inch (5 to 7 cm) diameter limbs. This performance may vary with user technique, chain sharpness, size, and type of wood. The 2.6 Ah Battery Pack will make up to 250 cuts. Cuts per charge will drop significantly with increasing diameter wood. The new 6.0 Ah Battery pack will bring 50% more run time compared with the 4.0 Ah Battery pack.

What is the difference between the Oregon CS300 and CS250 chainsaws?

The CS300 features brushless motor technology as well as increased power and torque, letting the user get more work done. The bar length has increased from 14" to 16" on the CS300 and it features tool-less chain tensioning. The CS300 has retained the patented PowerSharp® self-sharpening chain technology so you’ll never have to cut with a dull chain again.

How fast do the Oregon chainsaws (CS250 and CS300) cut?

In 3 to 6 inch (7 to 15 cm) diameter limbs, the chainsaw will take approximately 4 seconds, while large 8 to 10 inch (20 to 25 cm) diameter cuts will take approximately 25 seconds. This performance may vary with user technique, chain sharpness, and hardness of the wood.

What is PowerSharp® (the red lever) and how does it work?

PowerSharp is a chain sharpening system that is built-in to Oregon chainsaw models. When the chain is dull or not cutting fast enough, bring the chainsaw to full speed, pull the red lever for 3 to 5 seconds, and the chain will work like new. Expect approximately 10 to 20 resharpenings on an individual PowerSharp® chain depending on how much the chain was damaged prior to sharpening.

Can a non-PowerSharp® type chain be used on the CS300 chainsaw?

Yes. Other chains can be used on the chainsaw; however, the integrated sharpening feature will only work with PowerSharp chain. When installing another chain type, remove the sharpening stone as non-PowerSharp chains can be damaged by operating the red lever when a sharpening stone is installed. For the CS300, 3/8-in. Low Profile™, .050″ gauge chain with 56 drive links can be used as an alternate chain.

Can I put a shorter or longer guide bar on the saw?

It is not recommended to install a guide bar longer than 16 inches (40 cm) onto the CS300. The CS300 chainsaw has been designed with a 16 inch (40 cm) guide bar as the optimal length. Performance will decrease with a longer guide bar. Shorter guide bars with an A041 tail mount can be fitted to the CS300.

Does the chainsaw use bar and chain oil?

Yes. Bar and chain oil is required to properly lubricate the cutting system. Oregon Premium Bar and Chain Oil is recommended. Place the chainsaw on its side and fill the oil reservoir accessed through the oil cap. Check oil level each time you recharge the battery and fill as needed.

How do I tighten the chain on the CS300 chainsaw?

Always remove the battery and wear gloves when tightening the chain. Loosen the side cover release knob 1.5 turns (counter-clockwise). Use the red tensioning ring to tighten the chain, clockwise adds tension. Once the chain is at desired tension, tighten the side cover release knob.

How do I eject the battery on the CS300 chainsaws?

To remove the battery pack from the chainsaw, lift up on the release lever located below the battery pack to the right side of the rear handle.

If I overload the CS300, will the battery or saw be damaged?

No. The chainsaw is equipped with multiple protection features and will stop running before damage occurs.

BL300 Cordless Leaf Blower

When using the BL300 leaf blower, how long does the battery last?

A 4.0 Battery will last up to 90 minutes when using the BL300 on its lowest setting. It will last 15 minutes with the trigger pulled all the way to the high setting and 7 minutes with the Turbo Button pressed. The variable trigger on the BL300 allows the user to pick their desired power level and corresponding battery run time. The new 6.0 Ah Battery Pack will bring 50% more run time compared with the 4.0 Ah Battery pack.

How loud is my leaf blower?

The noise level for BL300 leaf blower is below 65 dB(A) when tested to ANSI B175.2. This is below the sound requirements for most areas that have bans on handheld blower noise.

Can I use the B500S 1.25 Ah battery pack?

If you use the BL300 with a B500S 1.25 Ah Battery, the Turbo Button will not function. The blower will still operate with the variable trigger but the Turbo Button will not activate the turbo mode. The tool is designed this way to protect the battery. The Turbo Button will function with all other Oregon® Battery Packs.

Why is my blower nozzle so difficult to install?

To insure that the nozzle fits the tool properly, it’s engineered to be very tight. Be sure to match up the alignment lugs on the blower tube with the alignment slots on the nozzle, then firmly attach the nozzle.

How do I eject the battery on my BL300 blower?

To remove the battery pack from the blower, lift up on the release lever located below the battery pack above the intake screen.

ST275 Cordless String Trimmer

How long does the battery last for the ST275 String Trimmer?

A 4.0 Ah Battery Pack will last up to approximately 45 minutes on one charge when powering the ST275 String Trimmer. This performance may vary with user technique and the type of grass or vegetation being trimmed. A 2.6 Ah Battery Pack will last up to approximately 30 minutes. The new 6.0 Ah Battery pack will bring 50% more run time compared with the 4.0 Ah Battery pack.

How does the line advance?

The ST275 String Trimmer utilizes a bump feed trimmer head. To advance the line, bump the trimmer head on the ground while the trimmer/edger is on.

Does the trimmer head need to be removed or opened to replace the line?

It depends on which trimmer head your ST275 is equipped with:

If the trimmer/edger is equipped with our standard, easy reload trimmer head (PN 564849) it's not necessary to disassemble the head in order to replenish the trimmer line.
If the trimmer/edger is equipped with an Oregon® Gator® SpeedLoad™ head (PN 581647), the disk of pre-wound, self-contained trimmer line is quickly replaced by disassembling the head—simply snap the top half of the head off, discard the spent trimmer line inside, insert a fresh disk of trimmer line, and snap the head back together. To learn more about Gator SpeedLoad, visit OregonProducts.com/GSL.

Can other trimmer line be used in the ST275?

It is not recommended to use larger diameter or round trimmer line in the ST275. The trimmer/edger has been designed to utilize .080″ diameter (2.0 mm) twisted trimmer line for optimal performance and run time. Larger diameter line or round line will decrease performance and run time.

Can another trimmer heads be used on this trimmer?

Yes. 2 heads are available:

the standard replacement trimmer head (Product Number 564849)
the new Gator SpeedLoad replacement head (Product Number 581647)

Can the handle be adjusted?

Yes. The ST275 features an adjustable front handle. Just move the handle forward or backward along the shaft until it is in a comfortable position for trimming, clearing or edging.

How does the tool convert from trimmer to edger?

The ST275 can quickly and easily be converted from trimmer to edger by simply flipping the edge guard down so that it protrudes from the trimmer and clicks into place.

If I overload the string trimmer, will the battery or trimmer be damaged?

No. The string trimmer is equipped with multiple protection features and will stop running before damage occurs.

PS250 Cordless Pole Saw

How long does the battery last on the PS250 Pole Saw?

A 4.0 Ah Battery Pack will last up to 500 cuts per charge in 2 to 3-in. (5 to 7 cm) diameter limbs. This performance may vary with user technique, chain sharpness, size, and type of wood. A 2.6 Ah Battery Pack will make up to 325 cuts. Cuts per charge will drop significantly with increasing diameter wood. The new 6.0 Ah Battery pack will bring 50% more run time compared with the 4.0 Ah Battery pack.

What length does the pole saw extend to?

The pole saw extends from 7’3″ to 10’4″ (2.2 m to 3.15 m) in length allowing up to approximately 15 feet (4.57 m) of access (based on a 5’10” individual operating at a 60 degree angle).

What types of chain can be used on the pole saw?

Micro-Lite ® Narrow-Kerf 3/8″ Low-Profile .043 gauge saw chain (Oregon R34, 90SG034G) is recommended for the PS250, but any 3/8" Low-Profile .043 gauge chain with 34 drive links will work.

Can I put another size guide bar on the pole saw?

Other bars with an A041 tail mount will fit on the PS250, but it is not recommended and may void the product warranty.

Does the pole saw use oil?

Yes. Bar and chain oil is required to properly lubricate the cutting system. Oregon Bar and Chain Oil is recommended for the PS250. Place the chain saw on its side and fill the oil reservoir accessed through the oil cap. Check oil level each before each use and fill as needed.

Is the knob on the cover of the pole saw used for tightening the chain?

No. The side cover knob tightens the guide bar against the chassis of the pole saw. Chain stretches in normal use and will need to be periodically re-tensioned. Use a screwdriver on the tension adjustment screw, located inboard of the guide bar on the front face of the pole saw, to adjust chain tension as described in the operator’s manual.

If I overload the pole saw, will the battery or saw be damaged?

No. The pole saw is equipped with multiple protection features and will stop running before damage occurs.

HT250 Cordless Hedge Trimmer

When using the HT250 hedge trimmer, how long does the battery last?

A 2.6 Ah Battery Pack will last for approximately 60 minutes of run time in the HT250 hedge trimmer. This performance may vary with user technique and the type of hedge being cut. A 4.0 Ah Battery Pack will last for up to 100 minutes of run time and the new 6.0 Ah Battery pack will bring 50% more run time compared with the 4.0 Ah Battery pack.

How do I turn on the HT250 hedge trimmer?

To turn on the HT250 hedge trimmer, start by grasping the front and rear handles firmly. Pull back on the trigger lock-out on the rear handle with your thumb while squeezing the variable speed trigger until the cutting blades move at the desired speed.

Can the blade on the HT250 be sharpened or replaced?

Yes. If the cutting blades are dull, blades can be file sharpened. If there is extensive damage, a replacement blade kit is available.

What is proper blade maintenance for the HT250?

Before each use, inspect the cutting blades. Make sure the cutting blades are sharp, have no nicks or blunt edges, and do not hang up or catch when running the hedge trimmer. Periodically file away nicks and burrs on the blades to ensure they move freely. When cutting hedges with heavy sap or in dusty environments, buildup of sap and dirt can occasionally cause blades to stick. To prevent this blade stick condition, clean the blades with a light coating of liquid silicon lubricant only on the lubrication area of the cutting blades and run the blades briefly to evenly distribute the lubricant. Sharp and free-moving cutting blades cut more easily than dull or sticky ones.

If I overload the HT250 hedge trimmer, will the battery or trimmer be damaged?

No. The trimmer is equipped with multiple protection features and will stop running before damage occurs.

Lawn Mowers, LM300 and LM400

How long does my battery last?
