WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND/
OR SERIOUS INJURY. THE TERM “POWER TOOL” IN ALL WARNINGS LISTED
BELOW REFERS TO YOUR ELECTRIC CHAINSAW.
WORK AREA
1. Keep work area clean and well lit. Cluttered and dark areas invite
accidents.
2. DO NOT operate power tools 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges or refrigerators. There is an increased risk of electric shock
if your body is earthed or grounded.
2. DO NOT expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. Use outdoor extension leads. If working outdoors, always use an approved
cable extension suitable for the power rating of this tool (see
specifications), the conductor size should also be at least the same size as
that on the machine, or larger. When using a cable reel, always unwind the
cable completely. We strongly recommend that this machine is
connected to the mains supply via a Residual Current Device (RCD).
PERSONAL SAFETY
1. 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 personal injury.
2. Use safety equipment. Always wear eye protection. Safety equipment such
as dust mask, non-skid safety shoes, or hearing protection used for
appropriate conditions will reduce personal injuries.
3. Avoid accidental starting. Ensure the switch is in the off position before
connecting to the power supply.
4. DO NOT overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
5. Dress properly. DO NOT wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
POWER TOOL USE AND CARE
1. 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 which it was designed.
2. 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.
3. Disconnect the power before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
4. Store idle 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.
5. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool and accessories in accordance with these instructions
and in the manner intended for the particular type of power tool, taking
into account the working conditions and the work to be performed. Use of
the power tool for operations different from intended could result in a
hazardous situation.
SERVICING
1. 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. Contact CLARKE service department for more detail.
1. Keep all parts of the body away from the saw chain when the chainsaw is
operating. Before you start the chainsaw, make sure the saw chain is not
contacting anything. A moment of inattention while operating chainsaws
may cause entanglement of your clothing or body with the saw chain.
2. It is recommended that the first time user should have practical instruction
in the use of the chainsaw and recommended protective equipment from
an experienced operator. The initial practice should be cutting logs on a
saw horse or cradle.
3. Keep handles dry, clean, and free from oil and grease. Greasy, oily handles
are slippery causing loss of control.
4. Always hold the chainsaw with your right
hand on the rear handle and your left
hand on the front handle, as shown.
Holding the chainsaw with a reversed
hand configuration increases the risk of
injury and should never be done.
5. Hold the chainsaw by insulated gripping
surfaces only, because the saw chain
may contact hidden wiring or its own
cable. Saw chains contacting a “live”
wire may make exposed metal parts of
the power tool “live” and could give the operator an electric shock.
6. Wear safety glasses and hearing protection. Further protective equipment
for head, hands, legs and feet must also be worn. Adequate protective
clothing will reduce personal injury by flying debris or accidental contact
with the saw chain.
7. DO NOT operate a chainsaw in a tree. Operation of a chainsaw while up in
a tree may result in personal injury.
8. Always keep proper footing and operate the chainsaw only when standing
on fixed, secure and level surface. Slippery or unstable surfaces such as
ladders may cause a loss of balance or control of the chainsaw.
9. When cutting a limb that is under tension be alert for spring back. When the
tension in the wood fibres is released the spring loaded limb may strike the
operator and/or throw the chainsaw out of control.
10. Use extreme caution when cutting brush and saplings. The material may
catch the saw chain and be whipped toward you or pull you off balance.
11. Carry the chainsaw by the front handle with the
chainsaw switched off and away from your
body. When transporting or storing the
chainsaw always fit the guide bar cover. Proper
handling of the chainsaw will reduce the
likelihood of accidental contact with the
moving saw chain.
12. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for
kickback.
13. Cut wood only. DO NOT use the chainsaw for
purposes not intended. For example: DO NOT use the chainsaw for cutting
plastic, masonry or non-wood building materials. Use of the chainsaw for
operations different than intended could result in a hazardous situation.
14. 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 chainsaw, but DO NOT use prolonged,
excessive pressure. Let the chainsaw do the work.
• Assure that the cutting system is maintained properly.
• Take frequent breaks.
15. Keep the power 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 minimise tripping hazards and prevent severing the cord with the
chainsaw.
16. If the cord is cut or damaged, immediately stop using the chainsaw and disconnect the cord from the mains. A damaged or cut cord increases the
risk of electrical shock.
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 upon the safety devices
built into your saw. As a chainsaw user, you should take several steps to keep
your cutting jobs free from accident or 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:
1. Maintain a firm grip, with thumbs and fingers encircling the chainsaw
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
chainsaw.
2. DO NOT overreach and DO NOT cut above shoulder height. This helps
prevent unintended tip contact and enables better control of the
chainsaw in unexpected situations.
3. Only use replacement bars and chains specified by the manufacturer.
Incorrect replacement bars and chains may cause chain breakage and/
or kickback.
KICKBACK SAFETY DEVICES ON THIS SAW
1. Chain Brake. This chainsaw comes
equipped with a chain brake, which
stops both the motor and the motion of
the chain when kickback occurs. 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.
2. Chain. This chainsaw comes equipped with a saw chain that meets the
reduced kickback performance requirements of ISO 9518.
3. 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.
The following symbols are displayed on the chainsaw in order to remind you of
the safety precautions you should take during operation.
Warning! - When using this chainsaw, basic
safety precautions, including those in this user
guide, should be observed to reduce the risk of
fire, electric shock and personal injury.
Warning! - Read this user guide thoroughly
before use and keep in a safe place for future
reference.
Warning! - Wear safety goggles, ear protectors
and safety helmet when using this chainsaw.
Warning! - DO NOT expose this chainsaw to
rain, or use in damp or wet locations.
Warning! - Disconnect from the mains supply
immediately if the cable is damaged or cut.
Warning! - Never cut with the tip of the blade
as this may result in kickback and cause
personal injury.
Warning! - Always wear gloves approved for
chainsaw use.
Warning! - Always hold the chainsaw with both
hands during use.

WARNING: FOR YOUR SAFETY AND THE SAFETY OF OTHERS MAKE SURE
THAT YOU HAVE READ AND UNDERSTOOD ALL THE SAFETY WARNINGS
BEFORE CONTINUING WITH THIS SECTION.
WARNING: ENSURE THAT THE CHAINSAW IS DISCONNECTED FROM THE
MAINS SUPPLY AND ALWAYS WEAR GLOVES DURING ALL CHECKS AND
ADJUSTMENTS IN THIS SECTION
CHECKING THE FRONT HAND-GUARD POSITION
After unpacking the chainsaw, check the
position of the front hand-guard. The
chainsaw will not run with the chain brake
engaged. Pull the front hand-guard back
forwards the front handle before operation,
as shown.
FILLING THE BAR AND CHAIN OIL RESERVOIR
WARNING: BAR AND CHAIN OIL PREVENTS PREMATURE WEAR. NEVER
OPERATE THE CHAINSAW IF OIL IS NOT VISIBLE IN THE RESERVOIR
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 chainsaw is equipped with an automatic oiler that deposits oil on
the bar and chain when running, keeping them properly lubricated. Always
use chainsaw oil for best results, as it is specially designed to provide low fiction
and faster cuts. NEVER use oil or other lubricants that have not been
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.
1. Place the chainsaw on a firm, flat surface
so that the oil cap is on top, as shown.
2. Clean any debris from the cap area.
3. Remove the cap.
4. Carefully pour the bar and chain oil into
the reservoir.
5. Replace the cap and make sure oil is
visible in the reservoir window.
PRIMING THE OILER
If this is the first time filling the bar and chain oil reservoir, or if the chainsaw has
been stored for a long period of time without use, prime the oiler, as follows:
1. Unplug the chainsaw.
2. Loosen the side cover release knob
slightly, but DO NOT remove the side
cover.
3. Loosen the chain tensioning ring that is
on the outside of the side cover release
knob (turn it anti-clockwise) as far as it will
go.
4. Loosen the side cover release knob and
remove the side cover.
5. Remove the guide bar and saw chain.
6. Install the side cover, then lightly tighten the side cover release knob.
7. Plug in the chainsaw.
8. Run the chainsaw for about two minutes.
9. Unplug the chainsaw, remove the side
cover and check for oil on the bar pad,
as shown.
10. If no oil is present on the bar pad,
replace the side cover and run for
another 30 seconds.
11. When oil begins to seep from the hole,
unplug the chainsaw and replace the
bar and chain as described in the next
section ‘Assembling the Guide Bar and
Saw Chain’.
2. Loosen the side cover release knob by
turning it counter clockwise, as shown,
then remove the side cover.
3. There is a rubber O-ring that is important
to the function of the saw, as shown. The
rubber O-ring must be in place around
the pin on the tensioner before the
tensioner is screwed onto the bar.
4. Insert the screw from the back side of the
chain tensioning gear and attach the
chain tensioning gear onto the guide
bar, as shown.
5. Place the chain tensioning gear on the
side of the guide bar facing you such
that the rectangular piece does not
protrude past the edges of the guide bar
and insert the screw.
6. Place the guide bar on the bar pad by
sliding the bar slot over the alignment
flange, as shown, with the mounting stud
inserted through the hole in the chain
tensioning gear.
7. Loop the new saw chain onto the drive
sprocket so that the cutting edge of the
teeth along the top of the bar face
away from the powerhead, as shown.
8. Feed the chain into the groove of the
bar and slide the bar away from the
motor to remove slack from the chain, as
shown.
9. Install the side cover, making sure the
chain catcher and side cover tab are
seated in their proper locations, as
shown, then lightly tighten the side cover
release knob.
10. Tension the chain as described in the
following section ‘Tensioning the Saw
Chain’.
TENSIONING THE SAW CHAIN
WARNING: IF THE CHAIN IS STILL LOOSE WHEN THE SAW IS AT MAXIMUM
TENSION, REPLACE THE CHAIN.
CAUTION: 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.
1. Unplug the chainsaw before tensioning.
2. Loosen the side cover release knob slightly, but DO NOT remove the side
cover.
3. Hold up the nose of the guide bar, as
shown, and turn the chain tensioning ring
clockwise.
4. Tighten the chain tensioning ring until the
lowest cutters underneath the bar solidly
contact the bar, as shown.
5. Tighten the side cover release knob.
6. Lightly pull on the chain. The tension is
correct when the chain snaps back after
being pulled 3mm away from the guide
bar.
7. After a short period of use, allow the
chain to cool, unplug the chainsaw 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 the chain when it is
hot.
NOTE: The 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.
WARNING: DO NOT START THE CHAINSAW UNTIL IT IS FULLY ASSEMBLED
AND ADJUSTED AND YOU HAVE READ ALL RELEVANT WARNINGS / SAFETY
INSTRUCTIONS.
For ‘first time’ users of this type of product, we recommend that introductory
training is undertaken from an experienced person before use.
PERSONAL PROTECTIVE EQUIPMENT
The following Personal Protective Equipment (PPE) available from you local
CLARKE dealer has been designed for use with chainsaws.
• A safety helmet with mesh visor.
• Ear defenders.
• Specialist chainsaw gloves.
• Trousers or chaps suitable for chainsaw use (they contain a clogging
material which stops the chain if cut).
• Safety boots with toe and shin protection.
• Close fitting hi-visibility jacket.
CAUTION: NO PPE WILL OFFER 100% PROTECTION AGAINST CHAINSAW
CUTS ESPECIALLY IF THE CHAINSAW IS USED IN A DANGEROUS MANNER.
GRIP
Always grip the tool with both hands. Grasp
the front handle with the left hand and the
rear handle with the right, as shown. Wrap
the fingers over the top of the handle with
the thumb below the handle.
CAUTION: THE CHAIN BRAKE HAS BEEN DESIGNED TO REDUCE THE
POSSIBILITY OF INJURY IF KICKBACK OCCURS. HOWEVER, IT CANNOT BE
RELIED UPON TO PROTECT YOU AGAINST INJURY IF THE CHAINSAW IS
USED CARELESSLY. TAKE GREAT CARE WHEN CUTTING, AND ALWAYS TEST
THE CHAIN BRAKE BEFORE USING THE CHAINSAW.
To check brake operation:
1. Place the saw on a firm flat surface with no obstructions to the chain.
2. Start the saw briefly.
3. Keep the left hand on the front handle
and roll the left wrist to move the front
hand guard forward to manually
activate the chain brake, as shown.
4. Release the trigger switch.
NOTE: A properly functioning chain brake
stops the motor and saw chain
immediately. If the motor and saw
chain do not stop immediately, have
the chain brake checked at an
approved service location before
using the chainsaw.
5. Return the front hand guard to operating position.
POWER CORD USE AND CARE
SELECTING AN EXTENSION CORD
Select an extension cord that is:
1. Specifically labeled for outdoor use.
2. Of a wire size 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 or in the specification
section of this manual.
Cord Length (M)Min. Diameter Wire Size
0 - 151.6277mm
16 - 302.0525mm
Make sure the insulation is free of cracks and that the plugs are undamaged.
It is important to use the strain relief bracket for two reasons:
1. It saves wear on both the power cord and the extension cord and their
plugs.
2. It prevents the chainsaw 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, as shown.
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 CHAINSAW 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 6M (20FT) PRIOR TO OPERATION OF
THIS EQUIPMENT. BYSTANDER SAFETY ZONE IS A
MINIMUM 6M (20FT) CIRCLE AROUND THE
OPERATOR THAT MUST REMAIN FREE FROM
BYSTANDERS, CHILDREN AND PETS. 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 to operate the saw safely, follow these
instructions:
1. Observe all applicable national and local rules and regulations for cutting.
2. Take frequent breaks to reduce the risk of injury.
3. 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 chainsaw 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:
1. The pressure required to make cuts increases noticeably.
2. 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 chainsaw and increase the risk of
kickback. NEVER force a dull chain to cut.
1. Assume the proper cutting grip and stance in front of the wood with the
saw turned off. Press the trigger switch. Let the chain reach full speed
before beginning the cut.
2. Begin cutting by lightly pressing the guide bar against the wood. Use only
light pressure and let the saw do the work.
3. Maintain a steady speed throughout the cut releasing pressure just before
the end of the cut.
4. Know the location of the cord at all times to avoid trip hazards and avoid
cutting the cord.
5. Know the location of the tip of the bar at all times and avoid contact with
other objects.
6. If the saw stops suddenly when cutting, remove the saw from the cut, then
resume cutting using lighter pressure on the work piece.
PRUNING
WARNING: 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.
1. 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.
2. 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.
3. Maintain solid footing and hold the chainsaw firmly with both hands. DO NOT overreach. NEVER climb a tree or ladder to reach high limbs.
7. Allow the saw chain to achieve full speed before cutting.
8. Apply light pressure to the branch.
9. For long limbs, cut the end of the limb first
(1) to relieve pressure from the limb, then
prune closer to the trunk (2), as shown.
10. Thick limbs (greater than 10cm (4 inch) 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 (1), then cut
the limb all the way through from the top
of the limb (2) to match the bottom cut,
as shown.
11. After most of the limb has been
removed, make one smooth cut near
the trunk, as shown.
WARNING: 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.
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 and plan your retreat route.
1. Remove dirt, stones, loose bark, nails,
staples and wire from the tree where
felling cuts are to be made.
2. 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.
3. 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.
4. 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
1. First, make a notch 1/3 the diameter of
the tree in the direction you want the
tree to fall. Make the lower horizontal
notching undercut first (1). This will help to
avoid pinching of either the saw chain or
the guide bar when the second cut (2) is
being made, as shown.
1. Second, make the felling back cut at
least 50mm (2 inch) higher than the
horizontal notching undercut, as shown.
Keep the felling back cut parallel to the
horizontal notching undercut.
2. 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.
3. As the felling cut gets close to the hinge, the tree should begin to fall under
its own weight.
4. 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 aluminium to
open the cut and drop the tree along the desired line of fall.
5. When the tree begins to fall, remove the chainsaw from the cut, stop the
motor, put the chainsaw down, then use the retreat path planned.
6. Be alert for overhead limbs falling and watch footing.
LIMBING A TREE
WARNING: LIMBS UNDER TENSION CAN SPRING BACK AND CONTACT
THE OPERATOR OR THROW THE CHAINSAW OUT OF CONTROL RESULTING
IN PERSONAL INJURY. ALWAYS BE ALERT FOR WOOD UNDER TENSION
WHICH MAY STRIKE THE OPERATOR OR CHAINSAW WHEN CUT.
Limbing is removing the branches from a fallen tree.
1. When limbing, leave large lower limbs to support the log off the ground.
2. Remove the small limbs in one cut.
3. Branches under tension should be cut
from the bottom up to avoid binding
the chainsaw, as shown.
WARNING: 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.
1. When the log is supported along its
entire length, cut from the top
(overbuck), as shown.
2. When the log is supported on one
end, cut 1/3 the diameter from the
underside (underbuck), then make
the finished cut by overbucking to
meet the first cut, as shown.
3. When the log is supported on both
ends, cut 1/3 of that diameter from
the top overbuck, then make the
finished cut by underbucking the

MAINTENANCE AND CLEANING
WARNING: FAILURE TO IDENTIFY AND REPLACE DAMAGED OR WORN
PARTS CAN CAUSE SERIOUS PERSONAL INJURY. INSPECT THE CHAINSAW
REGULARLY. REGULAR INSPECTION IS THE FIRST STEP TO PROPER
MAINTENANCE. FOLLOW THE GUIDELINES BELOW TO MAXIMISE SAFETY
AND SATISFACTION. HAVE ANY DAMAGED OR EXCESSIVELY WORN
PARTS REPLACE IMMEDIATELY.
WARNING: ALWAYS SWITCH THE CHAINSAW OFF, DISCONNECT FROM
THE POWER SUPPLY AND LET THE CHAINSAW COOL DOWN BEFORE
PERFORMING INSPECTION, MAINTENANCE AND CLEANING WORK!
INSPECTION
Before each use and if the chainsaw has been dropped, inspect these parts:
• Cord: Ensure the plug is in good condition and not bent or corroded,
and that the insulation is intact. If the cord is damaged, DO NOT USE.
Contact CLARKE parts/service department.
• Handles: Front and rear handles should not have cracks or other
damage. They should be clean and dry.
• Front Hand Guard: The front hand guard should be free of damage and
able to move easily back and forth. When moved, the front hand guard
should activate the chain brake.
• Guide Bar: The bar should be straight and free of chips, cracks or
excessive wear.
• Saw Chain: The chain should be properly tensioned and sharp and all
components free of cracks, chips, broken teeth or excessive wear. See
‘Tensioning the Saw Chain’ (pages 17-18) section.
• Side Cover: The side cover should be free of cracks or other damage. It
should fit tightly to the saw body with no warping. Make sure the chain
catcher is free of cracks.
• Chain Brake: Test the chain brake to make sure it is functioning properly.
See ‘Testing the chain brake’ section on page 21.
• Oil Level: Make sure the oil reservoir is full before use.
• Motor Housing: Check for cracks in the cover and debris in the air intake
vents.
Periodically inspect these parts:
• Drive Sprocket: Look for deep grooves, broken teeth or burrs.
• Chain Tensioning Gear: Inspect the gear for cracks, chips, loose screws,
warping or other damage.
• Bar Mounting Area Underneath Side Cover: Make sure the bar mounting
stud is not bent, stripped or cross threaded and that the bar pad and
alignment flange are free of debris and intact.
SHARPENING THE CHAIN
WARNING: SHARPENING THE CHAIN CAN PRODUCE LOW ENERGY
SPARKS. THE CHAIN SHOULD NOT BE SHARPENED IN THE PRESENCE OF
EXPOSED, EXTREMELY FLAMMABLE MATERIALS SUCH AS PETROL AND
ACETYLENE.
There are numerous types of chain sharpening devices on the market. The
following precautions should be adhered to.
1. A sharpener is designed specially for sharpening chainsaw chains. DO NOT
use it for any other purpose.
2. DO NOT sharpen damaged chainsaw chains.
3. DO NOT operate the sharpener without the relevant protective covers in
place.
4. ALWAYS adhere to the sharpeners user instructions and safety precautions.
WARNING: WHEN CLEANING THE CHAINSAW POWERHEAD, DO NOT
IMMERSE IN WATER OR OTHER LIQUIDS.
1. Always wear gloves when cleaning the chainsaw.
2. Unplug the chainsaw.
3. Remove wood chips and other debris from the motor housing and the
vents.
4. Always clean out wood chips, saw dust and dirt from the bar groove when
replacing the chain.
5. Make sure the cord and plug are dry before connecting to an outlet.
TENSIONING THE SAW 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.
If the chain does not touch the underside of the bar when the chainsaw is off
and cool, it should be tensioned.
Tension the chain as described in ‘Tensioning the Saw Chain’ section on
pages 17-18.
REPLACING A WORN SAW CHAIN
When the saw chain becomes cracked or has broken teeth, or is stretched to
the point that it cannot be kept at proper tension or simply cannot be
sharpened, it must be replaced.
1. Always wear gloves when handling the saw chain.
2. Unplug the chainsaw.
3. Loosen the side cover release knob slightly, but DO NOT remove the side
cover.
4. Loosen the chain tensioning ring (turn it anti-clockwise) as far as it will go.
5. Loosen the side cover release knob and remove the side cover.
7. Loop the new saw chain onto the drive
sprocket so that the cutting edges of the
teeth along the top of the bar face
away from the powerhead, as shown.
8. Feed the chain into the groove of the
bar and slide the bar away from the
motor to remove slack from the chain, as
shown.
9. Install the slide cover, making sure the
chain catcher and side cover tab are
seated in their proper locations, as
shown, then lightly tighten the side cover
release knob.
