Chain
saw
operating instructions
For assembly follow the procedure in the appropriate
section"Mounting Guide Bar and Chain'lofthis manual.
MAKITA chain, guide bar and sprocket must match
each other (see the appropriate section in this manual).
WARNING!
Proper tension
of
the chain is extremely important.
In order to avoid false setting the tensioning
procedure must be followed as described in this
manual. Always make sure the hexagonal nut(s)
for the sprocket guard is (are) tightened securely
after tensioning the chain. Check chain tension
once more after having tightened the nuts and
thereafter at regular intervals (always before starting
to
work). If the chain becomes loose while cutting,
shut
off
the engine and then tighten. Never
try
to
tighten the chain while the engine is running!
Fueling
Your MAKITA saw uses on oil-gasoline mixture for fuel
(see chapter "Fuel" of this manzal).

WARN IN G!
Gasoline is an extremely flammable fuel. Use
extreme caution when handling gasoline or fuel
mix.
Do
not smoke or bring any sparks or flame
near the fuel (fig.
5).
Fueling instructions
@
Fuel your chain saw in well ventilated areas or out-
doors. Always shut
off
the engine and allow
it
to cool
before refueling. Select bare ground for fueling and
move the chain saw at least
10
feet (3 m) from fueling
spot before starting the engine (fig. 5a).
Wipe
off
any spilled fuel before starting your saw and
check
for
leakage.
Check for fuel leakage while refueling and during
operation. If fuel or oil leakage is found, do not start or
run the engine until leak is fixed and spilled fuel has
been wiped away. Clothing with fuel on it has
to
be
changed immediately (this is a danger
to
your life!).
Avoid skin contact with fuel. Never loosen or remove
the cap of the fuel tank while the engine is running.
Starting
Do
not drop start. This method is very dangerous be-
cause you may lose control of the saw (fig. 6).

Place the chain saw on firm ground or other solid
surface in an open area. Maintain a good balance and
secure footing. Place your right
foot
through the rear
handle opening and firmly grasp the front handle with
your left hand (fig. 6a).
Be absolutely sure that guide bar and chain are clear
of you or all other obstructions and objects, including
the ground, because when the engine starts in semi-
throttle position, engine speed will be fast enough for
the clutch
to
engage the sprocket and turn the chain
which may cause a kickback.
Never attempt
to
start the saw when the guide bar is in
a cut or kerf.
When you pull the starter grip, don't wrap the starter
rope around your hands.
Do
not
allow the grip
to
snap
back, but guide the starter rope slowly back
to
permit
the rope
to
rewind properly. Failure
to
follow this
procedure may result in injury
to
hand or fingers and
may damage the starter mechanism.
