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 services performed by a
qualied 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 ywheel when
servicing the clutch, structural damage to the
ywheel can occur and cause the ywheel to
burst.
2. Make certain the saw chain stops moving
when the throttle trigger is released.
3. Never modify your saw in any way.
4. Keep the handles dry, clean, and free of oil or
fuel mixture.
5. Keep fuel and oil caps, screws, and fasteners
securely tightened.
6. Use only qualied 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 ame in the
areas where fuel is mixed or poured. There
should be no smoking, open ames, or work
that could cause sparks. Allow engine to cool
before refuelling.
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 metres 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
ames 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 ing 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 a 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 difcult
it becomes for the operator to control the saw.
Many factors inuence 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
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.
