SAFETY POINTS FOR
YOUR PETROL CHAIN SAW
WARNING! The saw is intended only for
the cutting of wood. The engine group
is intended only for use with the recommended
cutting equipment.
Before using the machine, read the
operating instructions carefully to
understand all of the content. Failure to
follow all instructions listed below may
result in fire and/or serious injury.
Only use this machine for usage
specifically mentioned in this manual.
READ THE INSTRUCTIONS
GENERAL SAFETY INSTRUCTIONS
PLAN AHEAD
1. Read this manual carefully until you
completely understand and can follow all
safety rules, precautions, and operating
instructions before attempting to use the unit.
2. Restrict the use of your saw to adult users
who understand and can follow safety rules,
precautions, and operating instructions found
in this manual.
3. Wear protective gear. Always use steel toed
safety footwear with non-slip soles; snug-
fitting clothing; heavy-duty, non-slip gloves;
eye protection such as non-fogging, vented
goggles or face screen; an approved safety
hard hat; and sound barriers (ear plugs or
mufflers) to protect your hearing. Regular
users should have hearing checked regularly
as chain saw noise can damage hearing.
Secure hair above shoulder length.
4. Keep all parts of your body away from the
chain when the engine is running.
5. Keep children, bystanders, and animals a
minimum of 10 meters away from the work
area. Do not allow other people or animals
to be near the chain saw when starting
or operating the chain saw. If necessary
use warning signs to keep on lookers at a
distance.
6. Do not handle or operate a chain saw when
you are fatigued, ill, or upset, or if you have
taken alcohol, drugs, or medication. You must
be in good physical condition and mentally
alert. Chain saw work is strenuous. If you
have any condition that might be aggravated
by strenuous work, check with your doctor
before operating a chain saw.
7. Carefully plan your sawing operation in
advance. Do not start cutting until you have
a clear work area, secure footing, and, if you
are felling trees, a planned retreat path. Do
not operate the chainsaw near a naked flame
or spilled fuel. After re-fueling, always wipe
off any spilled fuel, move the chainsaw away
from the fueling point before starting the
engine.
OPERATE YOUR SAW SAFELY
1. Do not operate a chain saw with one hand.
Serious injury to the operator, helpers,
bystanders or any combination of these
persons may result from one-handed
operation. A chain saw is intended for two-
handed use. Always maintain a firm foothold.
Ensure you are able to STOP the engine
quickly if necessary.
2. Operate the chain saw only in a well-
ventilated outdoor area.
3. Do not operate saw from a ladder or in a tree.
4. Make sure the chain will not make contact
with any object while starting the engine.
Never try to start the saw when the guide bar
is in a cut.
5. Do not put pressure on the saw at the end of
the cut. Applying pressure can cause you to
lose control when the cut is completed.
6. Stop the engine before setting the saw down.
7. Do not operate a chain saw that is damaged,
improperly adjusted, or not completely
and securely assembled. Always replace
bar, chain, hand guard, or chain brake
immediately if it becomes damaged, broken
or is otherwise removed.
8. With the engine stopped, hand carry the
chain saw with the muffler away from your
body, and the guide bar and chain to the rear,
preferably covered with a scabbard.
PHYSICAL CONDITION
You must be in good physical condition and
mental health and not under the influence of any
substance (drugs, alcohol), which might impair
vision, dexterity or judgment.
PROPER CLOTHING
Clothing must be sturdy and snug-fitting, but
allow complete freedom of movement. Avoid
loose-fitting jackets, scarfs, neckties, jewelry,
flared or cuffed pants, or anything that could
become entangled with the saw or brush.
Wear overalls or jeans with a reinforced cutting
resistant insert (A).
Protect your hands with gloves when handling
saw and saw chain. Heavy-duty, nonslip gloves
improve your grip and protect your hands.

3
Good footing is most important in chain saw
work.
Wear sturdy boots with nonslip soles. Steel-toed
safety boots are recommended.
Proper eye protection is a must. Non-
fogging, vented goggles and a face screen is
recommended. Their use reduces the risk of eye
and facial injury.
Wear an approved safety hard hat to protect
your head. Chain saw noise may damage your
hearing.
Always wear noise protection equipment (ear
plugs or ear muffs) to protect your hearing.
Continual and regular users should have their
hearing checked regularly.
A
MAINTAIN THE SAW IN GOOD WORKING
ORDER
1. Have all chain saw service performed by a
qualified service dealer with the exception of
the items listed in the maintenance section of
this manual. For example, if improper tools
are used to remove or hold the flywheel when
servicing the clutch, structural damage to the
flywheel can occur and cause the flywheel to
burst.
2. Make certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to:
CARBURETOR ADJUSTMENT.
1. Never modify your saw in any way.
2. Keep the handles dry, clean, and free of oil or
fuel mixture.
3. Keep fuel and oil caps, screws, and fasteners
securely tightened.
4. Use only qualified accessories and
replacement parts as recommended.
HANDLE FUEL WITH CAUTION
1. Do not smoke while handling fuel or while
operating the saw.
2. Eliminate all sources of sparks or flame in the
areas where fuel is mixed or poured. There
should be no smoking, open flames, or work
that could cause sparks. Allow engine to cool
before refueling.
3. Mix and pour fuel in an outdoor area on
bare ground; store fuel in a cool, dry, well
ventilated place; and use an approved,
marked container for all fuel purposes. Wipe
up all fuel spills before starting saw.
4. Move at least 3 meters from fueling site
before starting engine.
5. Turn the engine off and let saw cool in a non-
combustible area, not on dry leaves, straw,
paper, etc. Slowly remove fuel cap and refuel
unit.
6. Store the unit and fuel in an area where
fuel vapors cannot reach sparks or open
flames from water heaters, electric motors or
switches, furnaces, etc.
KICKBACK SAFETY PRECAUTIONS
WARNING! Kickback may occur when
the moving saw chain near the upper
quadrant of the bar nose contacts a solid object
or is pinched.
The reaction of the cutting force of the chain
causes a rotational force on the chainsaw in the
direction opposite to the chain movement. This
may fling the bar up and back in an uncontrolled
arc mainly in the plane of the bar. Under some
cutting circumstances the bar moves towards
the operator, who may suffer severe or fatal
injury.
Kickback may occur when the nose of the guide
bar is pinched unexpectedly, unintentionally
contacts solid material in the wood or is
incorrectly used to begin a plunge or boring cut.
It may also occur during limbing. The greater the
force of the kickback reaction, the more difficult
it becomes for the operator to control the saw.
Many factors influence the occurrence and force
of the kickback reaction. These include chain
speed, the speed at which the bar and chain
contact the object, the angle of contact, the
condition of the chain and other factors.
Pull-in occurs when the chain on the bottom of
the bar is suddenly stopped when it is pinched,
caught or encounters a foreign object in the
wood. The reaction of the chain pulls the saw
forward and may cause the operator to lose
control.
Pull-in frequently occurs when the bumper spike

4
of the saw is not held securely against the tree
or limb and when the chain is not rotating at full
speed before it contacts the wood.
WARNING! Use extreme caution when
cutting small size brush and saplings
which may easily catch the chain and pull you off
balance.
TO AVOID PULL-IN (B)
1. Always start a cut with the chain rotating at
full speed and the bumper spike in contact
with the wood.
2. Pull-in may also be prevented by using
wedges to open the kerf or cut.
B
Pushback occurs when the chain on the top of
the bar is suddenly stopped when it is pinched,
caught or encounters a foreign object in the
wood. The reaction of the chain drives the saw
straight back toward the operator and may cause
loss of saw control. Pushback frequently occurs
when the top of the bar is used for cutting.
TO AVOID PUSHBACK (C)
1. Be alert to forces or situations that may cause
material to pinch the top of the chain.
2. Do not cut more than one log at a time.
3. Do not twist the saw when withdrawing the
bar from a plunge cut or underbuck cut
because the chain can pinch.

DEVICES FOR REDUCING THE RISK OF
KICKBACK INJURY
Quickstop chain brake
WARNING! To reduce the risk of injury,
stop using the saw immediately if the
chain brake does not function properly. Take the
saw to your local Service Centre! Do not use the
saw until the problem has been rectified.
Chain brake is designed to stop the chain in
the event of kickback. When the chain brake/
hand guard is pushed towards the bar, the chain
should stop immediately. A chain brake does not
prevent kick-back; the chain brake should be
cleaned and tested daily.
Low kickback chain
“Low kickback saw chain” is a chain which has
met the kickback performance requirements.
Low--Kickback Chain, designed with a
contoured depth gauge and guard link which
deflect kickback force and allow wood to
gradually ride intothe cutter.
Reduced kickback bar
Reduced--Kickback Guide Bar, designed with
a small radius tip which reduces the size of the
kickback danger zone on the bar tip. A Reduced-
-Kickback Guide Bar has been demonstrated to
significantly reduce the number and seriousness
of kickbacks.
To avoid kickback
The best protection from personal injury that
may result from kickback is to avoid kickback
situations:
1. Hold the chainsaw firmly with both hands and
maintain a secure grip.
2. Be aware of the location of the guide bar nose
at all times.
3. Never let the nose of the guide bar contact
any object. Do not cut limbs with the nose of
the guide bar.
Be especially careful when cutting small,
tough limbs, small size brush and saplings
which may easily catch the chain.
4. Don’t overreach.
5. Don’t cut above shoulder height.
6. Cut only one log at a time.
8. Use extreme caution when reentering a
previous cut.
9. Do not attempt to plunge cut if you are not
experienced with these cutting techniques.
10. Be alert for shifting of the log or other forces
that may cause the cut to close and pinch the
chain.
11. Maintain saw chain properly. Cut with a
correctly sharpened, properly tensioned
chain at all times.
12. Stand to the side of the cutting path of the chainsaw.
