SAFETY RULES

GENERAL POWER TOOL SAFETY WARNINGS

WARNING: READ AND UNDERSTAND ALL SAFETY WARNINGS AND ALL

INSTRUCTIONS. FAILURE TO FOLLOW THE WARNINGS AND INSTRUCTIONS

MAY RESULT IN ELECTRIC SHOCK, FIRE AND/OR SERIOUS INJURY.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE. THE TERM “POWER TOOL” IN THE WARNINGS REFERS TO YOUR MAINS-OPERATED (CORDED) POWER TOOL OR BATTERY OPERATED (CORDLESS) POWER TOOL.

WORK AREA SAFETY

• Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

• Do not operate the power tool in

explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which

may ignite the dust or fumes.

• Keep children and bystanders away

while operating the power tool.

Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the

outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.

Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or

grounded surfaces, such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled

cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord

suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces

the risk of electric shock.

SAFETY RULES

OREGON® CHAIN SAW MODEL CS1500-091

F/N 570773 - AC 0614

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention

while operating power tools may result in serious personal injury.

• Use personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools

with your finger on the switch or energizing power tools that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the power tool on. A

wrench or a key left attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times (Fig. 1).

This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or

long hair can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use

of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do

the job better and safer at the rate for which it was designed.

• Do not use the power tool if the switch does not turn it on and off.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories or storing power tools. Such preventive

safety measures reduce the risk of starting the power tool accidentally.

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in

the hands of untrained users.

• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly

maintained power tools.

• Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

FIG. 1

SAFETY RULES

OREGON® CHAIN SAW

MODEL CS1500-091

F/N 570773 - AC 0614

• Use the power tool, accessories and tool bits, etc. in accordance with these instructions taking into account the working conditions and the work to be performed. Use of the power tool for

operations different from those intended could result in a hazardous situation.

SERVICE

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

CHAIN SAW SAFETY WARNINGS

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment

of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.

• Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle (Fig. 2). Holding the chain saw with a

reversed hand configuration increases the risk of personal injury and should never be done.

• Hold the power tool by insulated gripping surfaces only, because saw chain may contact hidden wiring or its own cord. Saw chains contacting a

“live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate

protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.

• Do not operate a chain saw in a tree.

Operation of a chain saw while up in a tree may result in personal injury.

• Always keep proper footing and operate the chain saw only when standing on a fixed, secure and level surface. Slippery or unstable surfaces may

cause a loss of balance or control of the chain saw.

• When cutting a limb that is under tension, be alert for spring back. When

the tension in the wood fibers is released the spring loaded limb may strike the operator and/or throw the chain saw out of control.

• Use extreme caution when cutting brush and saplings. The slender material

may catch the saw chain and be whipped toward you or pull you off balance.

FIG. 2

SAFETY RULES

OREGON® CHAIN SAW MODEL CS1500-091

F/N 570773 - AC 0614

• Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover (Fig. 3).

Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.

• Follow instructions for lubricating, chain tensioning and changing accessories. Improperly tensioned or

lubricated chain may either break or increase the chance of kickback.

• Keep handles dry, clean and free of oil and grease. Greasy, oily handles are

slippery causing loss of control.

• Cut wood only. Do not use the chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials. Use of the chain saw

for operations different than intended could result in a hazardous situation.

• It is recommended that the first time user should have practical instruction in the use of the chain saw and the recommended protective equipment from an experienced operator. The initial practice should be cutting logs on a saw-horse or cradle.

• Other than the wear parts identified in this manual, the chain saw has no user serviceable parts.

• The work piece, bar and chain can be hot after cutting. Wear gloves to avoid

burns.

• Prolonged use of power tools has been reported to cause vascular, muscular and/or neurological disorders (such as vibration white finger or Raynaud’s syndrome), particularly when operating the tool in cold weather. If you experience

numbness or loss of feeling in your extremities, stop using the tool until symptoms fade. To reduce the incidence of vibration induced trauma, follow these instructions:

– Wear gloves and keep hands and body

warm.

– Maintain a firm grip on the chain saw,

but do not use prolonged, excessive pressure. Let the chain saw do the work.

– Assure that the cutting system is

maintained properly.

– Take frequent breaks.

The vibration in normal use can differ from the stated values in this manual, depending on the material being cut, maintenance of the cutting system and other factors.

• Keep the cord behind you, and know the position of the cord at all times.

Keeping the cord behind you and knowing the position of the cord will help minimize tripping hazards and prevent severing of the cord with the chain saw.

• If the cord is cut or damaged, immediately stop using the chain saw and disconnect the cord from the mains. A damaged or cut cord increases the

risk of electrical shock.

• When used in a wet environment use a GFCI with a tripping current of less than 30mA. Use of a GFCI reduces the risk of electric shock.

FIG. 3

SAFETY RULES

OREGON® CHAIN SAW

MODEL CS1500-091

F/N 570773 - AC 0614

CAUSES AND OPERATOR PREVENTION OF KICKBACK

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact, in some cases, may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively on the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident and injury.

Kickback is the result of tool misuse and/ or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces.

Kickback forces can be controlled by the operator , if proper precautions are taken. Do not let go of the chain saw.

• Do not overreach and do not cut above shoulder height. This helps

prevent unintended tip contact and enables better control of the chain saw in unexpected situations.

• Follow the OREGON® sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height

can lead to increased kickback.

KICKBACK SAFETY DEVICES ON THIS SAW

DANGER: NEVER MODIFY OR ATTEMPT

TO DISABLE THE CHAIN BRAKE.

DANGER: ONLY USE REPLACEMENT BARS AND CHAINS SPECIFIED BY OREGON®. Incorrect replacement bars

and chains may cause chain breakage and increased risk of kickback injury.

CHAIN BRAKE

This chain saw comes equipped with a chain brake, which stops both the motor and the motion of the chain when kickback occurs (Fig. ). The chain brake can be activated by the forward motion of the front hand guard as the saw rotates backward during kickback; it can also be activated by the inertial forces generated from a kickback event.

CHAIN

This chain saw comes equipped with a saw chain that met the reduced kickback performance requirements of the American National Standards Institute (ANSI) and Canadian Standards Association (CSA), ANSI B. and CSA Z. respectively, when tested according to the provisions of the standards. For replacement chain, see “Specifications and Components” in this manual.

FIG. 4

SAFETY RULES

OREGON® CHAIN SAW MODEL CS1500-091

F/N 570773 - AC 0614

BAR

This saw comes equipped with a reduced kickback guide bar that has a small radius nose. Smaller radius noses have less potential for kickback than a bar of the same size with a larger nose radius.

When replacing the bar, only order the bar listed in this manual to maintain low kickback performance.

STORAGE, TRANSPORTING, AND DISPOSAL

STORING THE CHAIN SAW

• Unplug the chain saw.

• Inspect the cord for cuts or damage.

• Clean chain saw thoroughly.

FILLING THE BAR AND CHAIN OIL RESERVOIR

IMPORTANT: BAR AND CHAIN OIL PREVENTS PREMATURE WEAR. NEVER OPERATE THE CHAIN SAW IF OIL IS NOT VISIBLE IN THE INSPECTION WINDOW. CHECK OIL LEVEL FREQUENTLY AND FILL AS NEEDED.

Bar and chain oil is required to properly lubricate the guide bar and saw chain. The chain saw is equipped with an automatic oiler that deposits oil on the bar and chain when running, keeping them properly lubricated. Use OREGON® bar and chain oil for best results. It is specially designed to provide low friction and faster cuts. NEVER use oil or other lubricants not specifically designed for use on the bar and chain. This can lead to a clogged oil system which may cause premature wear of the bar and chain.

Place the chain saw on a firm, flat surface so that the oil cap is on top (Fig. ).

• Clean any debris from the cap area.

• Remove the cap.

• Carefully pour the bar and chain oil into

the reservoir.

• Replace the cap and make sure oil is

visible in the reservoir.

PRIMING THE OILER

WARNING: TO REDUCE THE RISK OF INJURY, NEVER RUN THE CHAIN SAW WITHOUT THE SIDE COVER.

CAUTION: KEEP HANDS, CLOTHING, AND HAIR AWAY FROM THE DRIVE SPROCKET WHEN PRIMING THE OILER.

If this is the first time filling the bar and chain oil reservoir, or if the chain saw has been stored for a long period of time without use, prime the oiler.

Wear gloves

• Unplug the chain saw.

• Loosen the side cover release knob

slightly, but do not remove the side cover.

• Loosen the chain tensioning ring (turn it

counterclockwise) as far as it will go.

• Loosen the side cover release knob and

remove the side cover.

• Remove the guide bar and saw chain.

• Plug in the chain saw.

• Install the side cover, then lightly tighten

the side cover release knob.

• Run the chain saw for about two minutes.

• Unplug the chain saw, remove the side

cover and check for oil on the bar pad (Fig ).

• When oil begins to seep from the hole, unplug the chain saw and replace the bar and chain as described in “Maintaining the Guide Bar”.

If oil is not visible in the reservoir, additional bar and chain oil is necessary.

TENSIONING THE SAW CHAIN

WARNING: AN ELECTRIC POWER TOOL THAT IS PLUGGED IN CAN START ACCIDENTALLY. UNPLUG THE CHAIN SAW BEFORE PREPARING FOR USE OR PERFORMING MAINTENANCE.

WARNING: IF THE CHAIN IS STILL LOOSE WHEN THE SAW IS AT MAXIMUM TENSION, REPLACE THE CHAIN.

IMPORTANT: ONLY TENSION THE SAW CHAIN WHEN THE CHAIN IS COOL. A HOT CHAIN MAY CONTRACT AND DAMAGE THE GUIDE BAR OR CHAIN AS IT COOLS.

Wear gloves.

• Unplug the chain saw before tensioning.

• Loosen the side cover release knob

slightly, but do not remove the side cover.

• Hold up the nose of the guide bar (Fig. )

and turn the chain tensioning ring clockwise.

• Tighten the chain tensioning ring until the lowest cutters underneath the bar solidly contact the bar (Fig. ).

• Saw chain tension is correct when, with some effort, a gloved hand can pull the chain smoothly around the bar. The chain should touch the underside of the bar rail (Fig. ).

• Tighten the side cover release knob.

• After a short period of use, allow the chain to cool, unplug the chain saw and check the tension again. Watch tension carefully for the first half-hour of use and periodically throughout the life of the chain readjusting as required when the chain and bar are cool to the touch. Never tension chain when it is hot.

Chain will stretch as a result of normal use, however, insufficient oil, aggressive use or failure to perform recommended maintenance can lead to premature stretching.

POWER CORD USE AND CARE

SELECTING AN EXTENSION CORD

Select an extension cord that is:

• Specifically labeled for outdoor use

• Of a wire size (AWG) heavy enough to carry the current the full length of the cable according to the table below

Select the gauge of extension cord based on the desired length and the electrical specifications found on the product label.

These are the recommended gauges based on the length of cord.

CORD LENGTH (FT) MIN WIRE SIZE

0–50 14 AWG (1.5mm2)

51–100 12 AWG (3.0mm2)

Make sure the insulation is free of cracks and that the plugs on both ends are undamaged.

USING THE STRAIN RELIEF BRACKET

It is important to use the strain relief bracket for two reasons:

• It saves wear on both the power cord and the extension cord and their plugs.

• It prevents the chain saw from becoming unplugged from the extension cord accidentally.

To use the strain relief bracket, bend the extension cord into a U-shape and put it through the hole in the rear handle. Slide the loop of cord over the hook and tug lightly until snug (Fig. ).

CUTTING

WARNING: TO REDUCE THE RISK OF INJURY, WEAR PROPER BOOTS, GLOVES, HEAD, EAR AND EYE PROTECTION.

WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, MAKE SURE THE CORD INSULATION IS INTACT AND THAT THE CORD IS IN A DRY LOCATION WHERE THERE IS NO DANGER OF IT BEING CUT OR TRIPPED OVER.

WARNING: TO REDUCE THE RISK OF INJURY, ALWAYS BE SURE OF FOOTING AND HOLD THE CHAIN SAW FIRMLY WITH BOTH HANDS WHILE THE MOTOR IS RUNNING.

WARNING: TO REDUCE THE RISK OF INJURY, PLAN AHEAD AND PLAN MULTIPLE ESCAPE PATHS BEFORE BEGINNING WORK.

CAUTION: ESTABLISH A BYSTANDER SAFETY ZONE OF 20 FT (6 M) PRIOR TO OPERATION OF THIS EQUIPMENT.

Bystander safety zone is a minimum 6 m (20 ft) circle around the operator that must remain free from bystanders, children and pets (Fig. 16). Felling operations require a larger safety zone according to the size of the tree, see “Felling a Tree” section.

IMPORTANT: PRACTICE CUTTING LOGS ON A SAWHORSE OR CRADLE UNTIL YOU BECOME COMFORTABLE OPERATING THE SAW.

To get the best performance and operate the saw safely, follow these instructions:

• Observe all applicable national and municipal rules and regulations for cutting.

• Take frequent breaks to reduce the risk of injury.

• Before beginning to cut, make sure the saw chain is properly tensioned and the chain is sharp.

Saw chains are made to cut wood only. Do not use the chain saw to cut any other materials, and do not allow the chain to come into contact with dirt, stones, nails, staples or wire. These materials are extremely abrasive and will wear away protective plating from the chain in a very short time.

Sharpen or replace the saw chain if any of these conditions occur:

• The pressure required to make cuts increases noticeably.

• Wood chips coming off of the chain are very fine or dust-like.

Do not work with a dull chain as it will increase the effort required to cut, cause jagged cuts, increase wear on the chain saw and increase the risk of kickback. Never force a dull chain to cut.

• Assume the proper cutting grip and stance in front of the wood with the saw turned off. Press the trigger lock-out and squeeze the trigger switch. Let the chain reach full speed before beginning the cut.

• Begin cutting by lightly pressing the guide bar against the wood. Use only light pressure and let the saw do the work.

• Maintain a steady speed throughout the cut releasing pressure just before the end of the cut.

• Know the location of the cord at all times to avoid trip hazards and avoid cutting the cord.

• Know the location of the tip of the bar at all times and avoid contact with other objects.

• If the saw stops suddenly when cutting, remove the saw from the cut, then resume cutting using lighter pressure on the workpiece.

PRUNING

CAUTION: FALLING LIMBS MAY BOUNCE OR “SPRING BACK” AFTER THEY HIT THE GROUND SO IT IS ESSENTIAL TO KEEP THE GROUND CLEAR TO PROVIDE MULTIPLE RETREAT PATHS. Clear the work

area and wear head protection.

Pruning is removing dead or overgrown branches to maintain plant health.

• Plan retreat paths before beginning to cut,

and make sure there are no obstructions. Always know how to get out of the way of falling branches.

• Make sure bystanders or helpers are a safe

distance from falling branches. Bystanders or helpers should not stand directly in front of or behind the operator. See Fig. .

• Maintain solid footing and hold the

chain saw firmly with both hands. Do not overreach. Never climb a tree or ladder to reach high limbs.

• Secure any branches that might be

hazardous.

• Use proper auxiliary equipment.

• Prune lower limbs before pruning higher

ones.

• Allow the saw chain to achieve full speed

before cutting.

• Apply light pressure to the branch.

• For long limbs (Fig. ), cut the end of the

limb first () to relieve pressure from the limb, then prune closer to the trunk ().

• Thick limbs (greater than  inch ( cm) in diameter) can splinter or pinch the chain when making a single cut from the top. To avoid pinching or splintering, first make one shallow relief cut on the bottom surface of the limb (), then cut the limb all of the way through from the top of the limb () to match the bottom cut (Fig. ).

• After most of the limb has been removed, make one smooth cut near the trunk (Fig. ).

FELLING A TREE

CAUTION: A TREE IS LIKELY TO ROLL

OR SLIDE DOWNHILL AFTER IT IS FELLED.

Plan and clear a retreat path before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall (Fig. 20).

Felling is cutting down a tree.

• Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall.

• Remove dirt, stones, loose bark, nails, staples and wire from the tree where felling cuts are to be made.

• When bucking and felling operations are being performed by two or more persons at the same time, separate the felling operation from the bucking operation by a distance of at least twice the height of the tree being felled.

• Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree contacts any utility line, immediately leave the area and notify the utility company.

• Use the metal spikes on the front of the saw to support the saw on the wood. Set metal spiked bumper into the wood and use as a leverage point to increase stability when cutting large diameter wood.

NOTCHING UNDERCUT

• First, make the notch / the diameter of the tree perpendicular to the direction of fall. Make the lower horizontal notching undercut first (). This will help to avoid pinching of either the saw chain or the guide bar when the second cut () is being made (Fig. ).

FELLING BACK CUT

• Second, make the felling back cut at least  in ( mm) higher than the horizontal notching undercut (Fig. ). Keep the felling back cut parallel to the horizontal notching undercut.

• Make the felling back cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.

• As the felling cut gets close to the hinge, the tree should begin to fall.

• If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminum to open the cut and drop the tree along the desired line of fall.

• When the tree begins to fall, remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned.

• Be alert for overhead limbs falling and watch footing.

LIMBING A TREE

CAUTION: LIMBS UNDER TENSION CAN “SPRING BACK” AND CONTACT THE OPERATOR OR THROW THE CHAIN SAW OUT OF CONTROL RESULTING IN PERSONAL INJURY. Always be alert for

wood under tension which may strike the operator or chain saw when cut.

Limbing is removing the branches from a fallen tree.

• When limbing, leave larger lower limbs to

support the log off the ground.

• Remove the small limbs in one cut.

• Branches under tension should be cut

from the bottom up to avoid binding the chain saw (Fig. ).

BUCKING A LOG

CAUTION: BUCKING LOGS UNDER TENSION INCREASES THE CHANCE OF KICKBACK. Use one of the methods below to

support the log when bucking.

Bucking is cutting a log into lengths. It is important to make sure footing is firm and weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs or chocks.

• When the log is supported along its entire

length, cut from the top (overbuck) (Fig. ).

• When the log is supported on one end,

cut / the diameter from the underside (underbuck), then make the finished cut by overbucking to meet the first cut (Fig. ).

• When the log is supported on both ends, cut / of that diameter from the top overbuck, then make the finished cut by underbucking the lower / to meet the first cut (Fig. ).

• When bucking on a slope, always stand on the uphill side of the log (Fig. ).

• To maintain complete control when cutting through, release the cutting pressure near the end of the cut without relaxing the grip on the chain saw handles.

• Don’t let the chain contact the ground.

• After completing the cut, wait for the saw chain to stop before you move the chain saw.

• Always stop the motor before moving from tree to tree.

SHARPENING WITH POWERSHARP®

WARNING: POWERSHARP® SHOULD NOT BE USED IN THE PRESENCE OF EXPOSED, EXTREMELY FLAMMABLE MATERIALS SUCH AS GASOLINE AND ACETYLENE.

CAUTION: SHARPENING WITH THE POWERSHARP® SYSTEM PRODUCES LOW ENERGY SPARKS.

CAUTION: THE POWERSHARP® INTEGRATED SHARPENING SYSTEM IS FOR USE ONLY WITH POWERSHARP® CHAIN. NEVER ATTEMPT TO SHARPEN OTHER CHAIN WITH THE INTEGRATED SHARPENER. DAMAGE TO THE CHAIN AND SHARPENER WILL OCCUR.

INTRODUCTION TO POWERSHARP®

This chain saw is equipped with the PowerSharp® integrated sharpening system, a fast and easy way to sharpen chain on the saw. It is time to sharpen the saw chain when cuts take longer or the wood chips become smaller, turning the saw to dust in extreme cases.

SHARPENING THE CHAIN IMPORTANT: POWERSHARP® CHAIN USES

UNIQUE TOP-SHARPENING CUTTERS AND CAN ONLY BE SHARPENED WITH A GENUINE POWERSHARP® SHARPENER.

• With the saw at full speed, lightly lift the PowerSharp® lever for – seconds (Fig. ). Sparks will be visible when the cutters are in contact with the sharpening stone.

• Make a test cut to determine if the chain has been sufficiently sharpened. If not, repeat the sharpening procedure until the chain is sufficiently sharp.

IMPORTANT: DO NOT APPLY TOO MUCH FORCE WHEN SHARPENING. EXCESSIVE FORCE CAN REDUCE THE PERFORMANCE OF THE SHARPENING STONE.

IMPORTANT: IT IS NORMAL TO SEE A SMALL AMOUNT OF SPARKS AND SMOKE DURING SHARPENING AS THE CUTTERS CONTACT THE STONE AND FRICTION HEATS THE CHAIN.

WHEN TO REPLACE THE SHARPENING STONE

The sharpening stone is designed to wear at the same rate as the chain. Always replace the stone when replacing the chain even if it appears to have more life. See “Replacing a Worn Saw Chain and Sharpening Stone” in this manual.
