Wipe off any spilled fuel before starting your saw and
check for leakage.
Check for fuel leakage while refueling and during opera-
tion. 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).
WARNING!
Gasoline is an extremely flammable fuel. Use ex-
treme 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).

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 pro-
cedure may result in injury to hand or fingers and may
damage the starter mechanism.

Chain saw operating instructions
For assembly follow the procedure in the appropriate
section "Mounting Guide Bar and Chain" of this manual.
DOLMAR chain, guide bar and sprocket must match each
other (see the appropriate section in this manual).
WARNING!
Proper tension of the chain is extremely impor-
tant. 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 DOLMAR saw uses on oil-gasoline mixture for
fuel (see chapter "Fuel" of this manual).
