IMPORTANT SAFETY INSTRUCTIONS
WA R N I N G
Read all safety warnings designated by the symbol
and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or injury.
READ ALL INSTRUCTIONS.
The term “power tool” in all of the warnings refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
1. Work area safety
A. Keep work area clean and well lit. Cluttered or dark areas invite accidents
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
C. Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2. Electrical safety
A. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
reduce risk of electric shock.
B. 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.
C. Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
D. 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.
E. 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.
F. If operating a power tool in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
NOTE: The term “residual current devide (RCD) may be replaced by the term ”ground fault circuit
interrupter (GFCI) or (earth leakage circuit breaker (ELCB)”.
3. Personal safety
A. Stay alert, watch what you are doing and use common sense when operating a power
medication. A moment of inattention while operating power tools may result in serious personal
injury.
B. 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.
C. 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
D. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to the power tool may result in personal injury.
E. Do not overreach. Keep proper footing and balance at all times. This enables better control
of the power tool in unexpected situations.
2
IMPORTANT SAFETY INSTRUCTIONS
F. 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.
G. 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 dust-related hazards.
4. Power tool use and care
A. 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.
B. 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.
C. 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.
D. 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.
E. 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.
F. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
G. Use the power tool, accessories and tool bits etc., 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
those intended could result in a hazardous situation.
5. Chain Saw Safety
A. Keep all parts of the body away from the saw chain when the chain saw is operating. Bofore
you start the chain saw, make sure the saw chain is not contacting anythiing. A moment of
inattention while operating chain saws may cause entanglement of your clothing or body with
the saw chain.
B. Always hold the chain saw with your right hand on the rear handle and your left hand on
the front handle. Holding the chain saw with a reversed hand configuration increases the
risk of personal injury and should never be done.
C. Hold the power tool by insulated gripping surfaces only, because the 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.
D. 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
E. Do not operate a chain saw in a tree.Operation of a chain saw while up in a tree may result
in personal injury.
F.
secure, and level surface.Slippery or unstable surfaces such as ladders may cause a loss of
balance or control of the chain saw.
G. When cutting a limb that is under tension be alert for spring back.When the tension in the
saw out of control.
H. 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.

IMPORTANT SAFETY INSTRUCTIONS
I. Carry the chain saw by the front handle with the chain saw switched off and away from your
of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
G. Follow instructions for lubricating, chain tensioning, and changing accessories.Improperly
tensioned or lubricated chain may either break or increase the chance for kickback.
K. Keep handles dry, clean, and free from oil and grease.Greasy, oily handles are slippery
causing loss of control.
L. Cut wood only. Do not use chain saw for purpose 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.
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 a
serious personal injury. Do not rely exclusively upon the safety devices build into your saw. As
a chain saw 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:
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.
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.
M.Contact of the guide-bar tip with any object should be avoided.
N. Tip contact may cause the guide bar to move suddenly upward and backward, which may cause
serious injury.
O. Always use two hands when operating the chainsaw.
Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs
may create a risk of injury and fire.
c) 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.
d) 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.

WA R N I N G ( P r o p o s i t i o n 6 5 )
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
lead from lead-based paints
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically treated lumber.
Your risk of exposure to these chemicals 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 dust masks that are speciall
particles.

SAFETY INFORMATION
KICKBACK (See Figure 1-2)
WA R N I N G
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 chain saw user, you should take several steps to keep your cutting jobs free from accident or
injury.
The following precautions should be followed to minimize kickback:
1.
unit is running. Place your right hand on the rear handle and your left hand on the front
with a stiff left arm will help you maintain control of the saw if kickback occurs.
2. Make sure that the area in which you are cutting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch, fence, or any other obstruction that could be
hit while you are operating the saw.
3. Always cut with the unit running. Fully squeeze the switch trigger and maintain cutting
speed.
4. Use only the replacement guide bars and low kickback chains sp ecifi ed by the
manufacturer for the saw.
With a basic understanding of kickback, you can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
Keep proper footing and balance at all times.
Do not cut above shoulder height or overreach when cutting.
Follow the sharpening and maintenance instructions for the saw chain.

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
B175.1. Low kickback/skip tooth saw chain is a chain that has met the kickback performance
requirements of ANSI B175.1 - 1991 (American National Standard for Power Tools - GasolinePowered Chain Saws-Safety Requirements) when tested on the representative sample of chain

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 with the saw idling.
Press the safety lock and squeeze the switch trigger then release 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 switch trigger 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.
WORK AREA PRECAUTIONS (See Figure 12)
Cut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no nonwood building materials.
Never allow children to operate the saw. Allow no person to use this chain saw who has not
read this operator’s manual or received adequate instructions for the safe and proper use of
this chain saw.
Keep everyone – helpers, bystanders, children, and animals – a SAFE DISTANCE from the
cutting area. During felling operations, the safe distance should be a 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
WA R N I N G
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.
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!

OPERATING YOUR CHAIN SAW
PROPER PROCEDURE FOR TREE FELLING (See Figure 13-16)
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
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
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 in 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.
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.

OPERATING YOUR CHAIN SAW
NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (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.
On large diameter trees, stop the back cut 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
not touch the chain. Drive wedges in, little by little, to help jack the tree over.
As tree starts to fall, stop the chain saw and put it down immediately. Retreat along the
cleared path, but watch the action in case something falls your way.

REMOVING BUTTRESS ROOTS (See Figure 17)
A buttress root is a large root extending from the trunk of the tree above the ground. Remove
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.
BUCKING (See Figure 18)
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, 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 chain saw when cutting through the log, release the cutting pressure near the
end of the cut without relaxing your grip on the chain saw handles. Do not 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.

under stress to prevent the bar and chain from pinching.
OVERBUCKING (See Figure 21)
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.
UNDERBUCKING (See Figure 22)
Begin on the under side of the log with the top of the saw against the log; exert light pressure
upward. During under bucking, the saw will tend to push back at you. Be prepared for this

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 chain saw.
Keep the tree between you and the chain saw while limbing. Cut from the side of the tree
opposite the branch you are cutting.

CUTTING SPRINGPOLES (See Figure 25)
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.
WA R N I N G
Springpoles are dangerous and could strike the operator, causing the operator to lose control of the
chain saw. This could result in severe or fatal injury to the operator.

MAINTENANCE
CAUTION
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next
use. Never tension a warm chain before storing as chains shrink when cool. This can damage the
chain, bar and saw.
CHAIN MAINTENANCE (see figure 35)
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:
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 center sharpen the chain.
Raker (Depth Gauge) Clearance
1/32 in. (0,79 mm)

Note:
Inspect the drive sprocket for wear or damage when replacing the chain. Have the drive sprocket
replaced by an authorized service center if there are any signs of wear or damage.
If you do not fully understand the correct procedure for sharpening the chain after reading the
instructions that follow, have the saw chain sharpened by an authorized service center or replace
with a recommended low-kickback chain.

MAINTAINING THE GUIDE BAR (See Figure 45)
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.
