WARNING: Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire, and/or serious
personal injury.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate chainsaw in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Chainsaws create sparks which may ignite the dust or
fumes.
• Keep all children, bystanders, visitors, and animals out of the work area while starting
or cutting with the chainsaw. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Chainsaw plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) chainsaws.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 the chainsaw to rain or wet locations. Water entering a chainsaw will
increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
chainsaw. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
• When operating a chainsaw outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a
chainsaw. Do not use a chainsaw while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating chainsaws may result in
serious personal injury.
• Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
• Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your finger on the switch or plugging in 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 chainsaw may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better
control of the chainsaw in unexpected situation.
• 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.
• If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dustrelated hazards.
SAVE THESE INSTRUCTIONS!

CHAINSAW USE AND CARE
• Do not force the chainsaw. Use the correct chainsaw for your application. The correct
chainsaw will do the job better and safer at the rate for which it was designed.
• Do not use the chainsaw if the switch does not turn it on and off. Any chainsaw that
cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments changing
accessories, or storing chainsaws. Such preventive safety measures reduce the risk of
starting the chainsaw accidentally.
• Store idle chainsaws out of the reach of children and do not allow persons unfamiliar
with the chainsaw or these instructions to operate the chainsaw. Chainsaws are
dangerous in the hands of untrained users.
• Maintain chainsaws. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the chainsaw’s operation. If damaged,
have the chainsaw repaired before use. Many accidents are caused by poorly maintained
chainsaws.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
• Use the chainsaw, 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
chainsaw for operations different from those intended could result in a hazardous situation.
BATTERY USE AND CARE
• Recharge only with the charger specified by the manufacturer. A charger that is suitable
for one type of battery pack may create a risk of fire when used with another battery pack.
• Use blower only with specifically designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper
clips, coins, keys, nails, screws, or other small metal objects, that can make a
connection from one terminal to another. Shorting the battery terminals together may
cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause irritation or burns.
SERVICE
• Have your chainsaw serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the chainsaw is maintained.
• Servicing requires extreme care and knowledge and should be performed only by a
qualified service technician. For service we suggest you return the product to your nearest
AUTHORIZED SERVICE CENTER for repair. When servicing, use only identical replacement
parts.
SPECIFIC SAFETY WARNINGS
• 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.
!
Note: The size of the work area depends on the job being performed as well
as the size tree or work piece involved. For example, felling a tree requires
a larger work area than making bucking cuts.

• Always hold the chainsaw with your right hand on the rear handle and your left hand on
the front handle. Holding the chainsaw with a reversed hand configuration increases the risk of
personal injury and should never be done.
• Hold the chainsaw by insulated gripping surfaces only, because the saw chain may
contact hidden wiring or its own cord. Saw chains contacting a ²live² wire may make exposed
metal parts of the chainsaw ²live² 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 chainsaw in a tree. Operation of a chainsaw while up in a tree may result in
personal injury.
• 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.
• 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.
• 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.
• 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.
• Always use two hands when operating the chainsaw.
• Contact of the guide-bar tip with any object should be avoided.
• Tip contact may cause the guide bar to move suddenly upward and backward, which
may cause serious injury.
• Follow instructions for lubricating, chain tensioning and changing accessories.
Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery
causing loss of control.
• Cut wood only. Do not use chainsaw for purposes not intended. For example: do not
use 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.
! WARNING: Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities contain chemicals known to cause cancer,
birth defects or other reproductive harm. Some examples of these chemicals
are:
1. Lead from lead-based paints.
2. Crystalline silica from bricks and cement and other masonry products, and
3. Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemicals, work in a well-ventilated
area, and work with approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.
9
CAUSES AND OPERATOR PREVENTION OF KICKBACK
• 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.
Rotational
Kickback
Kickback
Danger Zone
• 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.
• Only use replacement bars and chains specified by the manufacturer. Incorrect
replacement bars and chains may cause chain breakage and/or kickback.
• Follow the manufacturer’s sharpening and maintenance instructions for the saw
chain. Decreasing the depth gauge height can lead to increased kickback.
• With a basic understanding of kickback, you can reduce or eliminate the element of
surprise. Sudden surprise contributes to accidents.

General Safety Rules
UNDERSTANDING YOUR CHAINSAW SAFETY DEVICES
LOW-KICKBACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can minimize the force of a kickback reaction
by preventing the cutters from digging in too deeply at the kickback zone. Only use replacement
chain that is equivalent to original chain or has been certified as low kickback chain per ANSI
B175.1. Low-kickback/skip tooth saw chain is a chain that has met the kickback performance
requirements of ANSI B175.1 - 1991. When tested on the representative sample of chainsaws
below 3.8 c.i.d. specified in ANSI B175.1 - 1991. As saw chains are sharpened during their
useful life, they lose some of the low-kickback qualities and extra caution should be used.
! WARNING: Kickback may occur when the moving chain contacts an object
at the upper portion of the tip of the guide bar or when the wood closes in and
pinches the saw chain in the cut. Contact at the upper portion of the tip of the
guide bar can cause the chain to dig into the object and stop the chain for an
instant. The result is a lightning fast reverse reaction which kicks the guide bar
up and back toward the operator. If the saw chain is pinched along the top of the
guide bar, the guide bar can be driven rapidly back toward the operator. Either of
these reactions can cause loss of saw control which can result in serious injury.
Do not rely exclusively upon the safety devices built into the saw. As a chainsaw
user, you should take several steps to keep your cutting jobs free from accident
or injury.

PREPARING FOR CUTTING
A. Proper grip on handles
See General Safety Rules for appropriate safety equipment.
• Wear non-slip gloves for maximum grip and protection.
• Maintain a proper grip on the saw whenever the motor is running. The fingers should
encircle the handle and the thumb is wrapped under the handlebar. This grip is least likely
to be broken by a kickback or other sudden reaction of the saw. Any grip in which the
thumb and fingers are on the same side of the handle is dangerous because a slight kick of
the saw can cause loss of control.

PROPER CUTTING STANCE
•
•
Operation
•
•
Balance your weight with both feet on solid ground.
Keep left arm with elbow locked in a “straight arm” position to withstand any kickback
force.
Keep your body to the left of the chain line.
Keep your thumb on underside of front handle.
BASIC OPERATING/CUTTING PROCEDURES
Practice cutting a few small logs using the following technique to get the “feel” of using the saw
before you begin a major sawing operation.
•
Take the proper stance in front of the wood.
•
Press the safety lock and squeeze the trigger switch then release the safety lock and let
the chain accelerate to full speed before entering the cut.
•
Begin cutting with the saw against the log.
•
Keep the unit running the entire time you are cutting, maintain a steady speed.
•
Allow the chain to cut for you; exert only light downward pressure. Forcing the cut could
result in damage to the bar, chain, or motor.
•
Release the trigger switch as soon as the cut is completed, allowing the chain to stop. If
you run the saw without a cutting load, unnecessary wear can occur to the chain, bar, and
unit.
•
Do not put pressure on the saw at the end of the cut.

Cut only wood or materials made from wood: no sheet metal, no plastics, no masonry, no
non-wood building materials.
Never allow children to operate the saw. Allow no person to use this chainsaw who has
not read this instruction manual or received adequate instructions for the safe and proper
use of this chainsaw.
Keep everyone — helpers, bystanders, children, and animals — a SAFE DISTANCE from
the cutting area. During felling operations, the safe distance should be at least twice the
height of the largest trees in the felling area. During bucking operations, keep a minimum
distance of 15’ (4.6 m) between workers.
Always cut with both feet on solid ground to prevent being pulled off balance.
Do not cut above chest height as a saw held higher is difficult to control against kickback
forces.
Do not fell trees near electrical wires or buildings. Leave this operation for professionals.
Cut only when visibility and light are adequate for you to see clearly.

FELLING TREES
HAZARDOUS CONDITIONS
!
WARNING:
• Do not cut down trees having an extreme lean or large trees with
rotten limbs, loose bark, or hollow trunks. Have these trees pushed
or dragged down with heavy equipment, then cut them up.
• Do not cut trees near electrical wires or buildings.
• Check the tree for damaged or dead branches that could fall and hit you
during felling.
• Periodically glance at the top of the tree during the backcut to assure the
tree is going to fall in the desired direction.
• If the tree starts to fall in the wrong direction, or if the saw gets caught or
hung up during the fall, leave the saw and save yourself.
• Do not fell trees during periods of high wind or heavy precipitation. Wait
until the hazardous weather has ended. When felling a tree, it is important
that you heed the following warnings to prevent possible serious injury.

REMOVING BUTTRESS ROOTS
Operation
A buttress root is a large root extending from the trunk of the tree above the ground. Remove
large buttress roots prior to felling. Make the horizontal cut into the buttress first, followed by
the vertical cut. Remove the resulting loose section from the work area. Follow the correct tree
felling procedure as stated in Proper Procedure For Tree Felling after you have removed the
large buttress roots.

PROPER PROCEDURE FOR TREE FELLING
•
•
•
•
•
•
Felling a tree — When bucking and felling operations are being performed by two or
more persons at the same time, the felling operation should be separated 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 does make contact with any utility line, the utility
company should be notified immediately.
Operator should keep on the uphill side of terrain as the tree is likely to roll or slide after
it is felled.
Pick your escape route (or routes in case the intended route is blocked). Clear the
immediate area around the tree and make sure there are no obstructions in your planned
path of retreat. Clear the path of safe retreat approximately 135° from the planned line of
fall.
Consider the force and direction of the wind, the lean and balance of the tree, and the
location of large limbs. These things influence the direction in which the tree will fall. Do
not try to fell a tree along a line different from its natural line of fall.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts
are to be made.
Notched Undercut, cut a notch about 1/3 the diameter of the trunk on the side of the tree.
Make the notch cuts so they intersect at a right angle to the line of fall. This notch should
be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always
make the lower cut of the notch before the upper cut.
21
•
•
•
Felling Backcut, as the felling cut gets close to the hinge, the tree should begin to fall.
If there is any chance the tree may not fall in the desired direction or it may rock back
and bind the saw chain, stop cutting before the felling cut is complete and use wedges
of wood, plastic or aluminum to open the cut and drop the tree along its desired line of
fall. Make the backcut level and horizontal, and at a minimum of 2” (5 cm) above the
horizontal cut of the notch.
On large diameter trees, stop the backcut before it is deep enough for the tree to either
fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so
they do.
As tree starts to fall, stop the chainsaw and put it down immediately. Retreat along the
cleared path, but watch the action in case something falls your way.

NOTE: Never cut through to the notch. Always leave
a band of wood between the notch and backcut
(approximately 2” (5 cm) or 1/10 the diameter of the tree).
This is called “hinge” or “hingewood.” It controls the fall
of the tree and prevents slipping or twisting or shoot back
of the tree off the stump.

Operation
BUCKING
Bucking is the term used for cutting a fallen tree to the desired log length.
• Always make sure your footing is secure and your weight is distributed evenly on both
feet.
• Cut only one log at a time.
• Support small logs on a saw horse or another log while bucking.
• Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and
chain during cutting as this can cause kickback. Refer to Kickback earlier in this manual.
• When bucking on a slope, always stand on the uphill side of the log. To maintain
complete control of the chainsaw when cutting through the log, release the cutting
pressure near the end of the cut without relaxing your grip on the chainsaw handles. Do
not let the chain contact the ground. After completing the cut, wait for the saw chain to
stop before you move the chainsaw. Always stop the motor before moving from tree to
tree.
KICKBACK
BUCKING WITH A WEDGE
If the wood diameter is large enough for you to insert a soft bucking wedge without touching
the chain, you should use the wedge to hold the cut open to prevent pinching.

OVERBUCKING
Begin on the top side of the log with the bottom of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull away from you.
OVERBUCKING
UNDERBUCKING
Begin on the under side of the log with the top of the saw against the log; exert light pressure
upward. During underbucking, the saw will tend to push back at you. Be prepared for this
reaction and hold the saw firmly to maintain control.
UNDERBUCKING
Operation
When the log is supported on one end, cut 1/3 the diameter from the underside. Then make
the finished cut by overbucking to meet the first cut. When the log is supported on both ends,
cut 1/3 of the diameter from the top overback. Then make the finished cut by underbucking the
lower 2/3 to meet the first cut.

Operation
LIMBING
Limbing is removing branches from a fallen tree.
• Work slowly, keeping both hands on the chainsaw with a firm grip. Always make sure
your footing is secure and your weight is distributed evenly on both feet.
• Leave the larger support limbs under the tree to keep the tree off the ground while
cutting.
• Limbs should be cut one at a time. Remove the cut limbs from the work area often to
help.
• Keep the work area clean and safe.
• Branches under tension should be cut from the bottom up to avoid binding the
chainsaw.
• Keep the tree between you and the chainsaw while limbing. Cut from the side of the
tree opposite the branch you are cutting.
PRUNING
Pruning is trimming limbs from a live tree.
• Work slowly, keeping both hands on the chainsaw with a firm grip. Always make sure
your footing is secure and your weight is distributed evenly on both feet.
• Do not cut from a ladder. This is extremely dangerous. Leave this operation for
professionals.
• Do not cut above chest height as a saw held higher is difficult to control against
kickback.
• When pruning trees it is important not to make the finishing cut next to the main limb
or trunk until you have cut off the limb further out to reduce the weight. This prevents
stripping the bark from the main member.
• Underbuck the branch 1/3 through for your first cut.
• Your second cut should overbuck to drop the branch off.
• Now make your finishing cut smoothly and neatly against the main member so the bark
will grow back to seal the wound.

CUTTING SPRINGPOLES
A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other
wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted
stump has a high potential of springing back to the upright position during the bucking cut to
separate the log from the stump. Watch out for springpoles — they are dangerous.
Springpole
!
WARNING: If the limbs to be pruned are above chest height, hire a
professional to perform the pruning.
!
WARNING: Springpoles are dangerous and could strike the
operator, causing the operator to lose control of the chainsaw.
This could result in severe or fatal injury to the operator.
Operation
When bucking on a slope always stand on the uphill side of the log. To maintain complete
control of the chainsaw when cutting through the log, release the cutting pressure near the end
of the cut without relaxing your grip on the chainsaw handles. Don’t let the chain contact the
ground. After completing the cut wait for the saw chain to stop before you move the chainsaw.
Always stop the motor before moving from tree to tree.

Position the chain so there is a loop at the back of the bar.
Hold the chain in position on the bar and place the loop around the sprocket.
Fit the bar flush agaist the mounting surface so that the bar studs are in the long shot
of the bar.
Replace the chain cover.
Replace the sleeve and chain cover lock bolt; use a hexagon ring spanner to rotate
bolt clockwise to tension. The bar should still be free to move for tension adjustment.
Remove all slack from the chain by turning the chain tensioning bolt clockwise with a
hexagon ring spanner until the chain seats snugly against the bar with the drive links in
the bar groove.

chain sharpened by an authorized service centre or replace with a
recommended low-kickback chain.
MAINTENANCE
CHAIN MAINTENANCE
Use only a low-kickback chain on this saw. This fast-cutting chain provides kickback
reduction when properly maintained. For smooth and fast cutting, maintain the chain
properly. The chain requires sharpening when the wood chips are small and powdery, the
chain must be forced through the wood during cutting, or the chain cuts to one side. During
maintenance of the chain, consider the following:
•
Improper filing angle of the side plate can increase the risk of severe kickback
•
Raker (depth gauge) clearance.
•
Too low increases the potential for kickback.
•
Not low enough decreases cutting ability.
•
If the cutter teeth hit hard objects such as nails or stones, or are abraded by mud or
sand on the wood, have an authorized service centre sharpen the chain.
MAINTENANCE

model no. 054-5756-6 | contact us: 1.866.523.5218
SHARPENING THE CUTTERS
•
Be careful to file all cutters to the specified angles and to the same length, as fast
cutting can be obtained only when all cutters are uniform.
•
Tension the chain prior to sharpening. Refer to Adjusting The Chain Tension.
•
Use a 5/32’’ (4 mm) diameter round file and holder. Do all of your filing at the midpoint
of the bar.
•
Keep the file level with a top plate of the tooth. Do not let the file dip or rock.
•
Using light but firm pressure. Stroke towards the front corner of the tooth.
•
Lift the file away from the steel on each return stroke.
•
Put a few firm strokes on every tooth. File all left hand cutters in one direction. Then
move to the other side and file the right hand cutters in the opposite direction.
•
Remove filings from the file with a wire brush.

Maintain the depth gauge at a clearance of 1/32” (0.6 mm). Use a depth gauge tool
for checking the depth gauge clearances.
•
Every time the chain is filed, check the depth gauge clearance.
•
Use a flat file and a depth gauge jointer to lower all gauges uniformly. Use a 1/32”
(0.6 mm) depth gauge jointer. After lowering each depth gauge, restore original
shape by rounding the front. Be careful not to damage adjoining drive links with the
edge of the file.
•
Depth gauges must be adjusted with the flat file in the same direction the adjoining
cutter was filed with the round file.
•
Use care not to contact cutter face with flat file when adjusting depth gauges.

MAINTAINING THE GUIDE BAR
Every week of use, reverse the guide bar on the saw to distribute the wear for maximum
bar life.
The bar should be cleaned every day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar wear. Such faults should
be smoothed with a file as soon as they occur. A bar with any of the following faults
should be replaced:
•
Wear inside the bar rails that permits the chain to lay over sideways.
•
Bent guide bar.
•
Cracked or broken rails.
•
Spread rails.
Lubricate guide bars weekly with a sprocket at their tip. Using a grease syringe, lubricate
weekly in the lubricating hole. Turn the guide bar and check that the lubrication holes
and chain groove are free from impurities.
