Checking the chain lubrication
E
Never work with the chain saw withoute sufficient chain
lubrication. Otherwise the service life of the chain and guide
bar will be reduced.
Before starting work check the oil level in the tank and the oil
feed.
Check the oil feed rate as described below:
- Start the chain saw.
- Hold the running chain saw approx. 15 cm above a trunk
or the ground (use an appropriate base).
If the lubrication is sufficient, you will see a light oil trace
because oil will be flung off the sawing device. Pay attention to
the direction the wind is blowing and avoid unnecessary
exposure to the oil spray!

Checking the chain brake
Do not work with the chain saw without first checking
the chain brake!
- Start the engine as described (make sure you have a good
footing, and place the chain saw on the ground in such a
way that the guide bar is free of contact).
- Grasp the tubular handle firmly with one hand and hold the
grip with the other.
- With the engine running at moderate speed, press the hand
guard (D/6) in the direction of the arrow with the back of
your hand until the chain brake engages. The chain should
stop immediately.
- Immediately release the throttle and release the chain
brake.
Caution: If the chain does not stop immediately in this
test, turn off the engine immediately. Do NOT use the
chain saw in this condition! Contact a DOLMAR service
center.
Adjusting the carburetor
IMPORTANT: Carburetor adjustment may be done only by
a DOLMAR service center!
Do not undertake adjustments to the adjusting screws (H)
and (L) without a tachometer! Improper adjustment can
lead to engine damage!
The adjusting screws (H) and (L) are factory set almost all the
way out (turned counterclockwise).
A tachometer (F/1) is necessary to adjust the adjusting
screws (H) and (L), because exceeding the permissible
maximum speed leads to overheating and under-lubrica-
tion.
This can damage the engine!
The only user-adjustable setting is the idle adjusting
screw (speed). If the blade rotates in idle (without the throttle
pressed), it is absolutely necessary to correct the idle
speed before using the tool!
Do not adjust the idle speed until the machine has been
completely assembled and checked!
Adjust the idle speed only with the engine warm, a clean
air filter, and properly installed cutting tool.
Use a screwdriver (F/2, blade width 4 mm, part No. 944 340
001) to adjust the screw.
