N
Start and warm up the engine if
necessary.
Chain rotates when engine is idling
Spark Plug
N
Turn the idle speed screw (LA)
counterclockwise until the chain
stops moving and then turn the
screw another full turn in the same
direction.
Adjust idle speed with the idle speed
screw (LA) so that the saw chain
does not rotate.
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
Fine Tuning for Operation in
Mountains or at Sea Level
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
If the saw chain continues to
rotate when the engine is idling,
have your machine checked and
repaired by your servicing dealer.
A slight correction of the setting may be
necessary if engine power is not
satisfactory when operating at high
altitude or at sea level.
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
Erratic idling behavior, engine stops
even though setting of LA-screw has
been corrected, poor acceleration
unfavorable running conditions (mostly
at part throttle etc.) affect the condition
of the spark plug. These factors cause
deposits to form on the insulator nose
which may result in trouble in operation.
N
Warm up the engine.
Idle setting is too lean
At high altitude
Turn high speed screw (H)
N
Turn the low speed screw (L)
counterclockwise, no further than
stop, until the engine runs and
accelerates smoothly.
N
Removing the Spark Plug
clockwise (leaner) – no further than
stop.
N
Shut off the engine
At sea level
Turn high speed screw (H)
Erratic idling behavior, engine speed
drops when swinging the machine
N
1
counterclockwise (richer) – no
further than stop.
Idle setting is too rich
N
Turn the low speed screw (L)
clockwise (1/8 of a turn or 45° at a
time) until the engine runs smoothly
and accelerates well.
Adjusting Idle Speed
Warm up the engine.
Engine stops while idling
N
It is usually necessary to change the
setting of the idle speed screw (LA) after
corrections to the low speed screw (L).
The spark plug boot (2) sits inside the
cap (1).
N
Turn the idle speed screw (LA)
slowly clockwise until the engine
runs smoothly – the saw chain must
not rotate.
The cap (1) protects the spark
plug boot from damage. Do not
operate the machine without a
cap – replace a damaged cap.
N
N
Pull off the spark plug boot (2)
together with the cap (1).
Unscrew the spark plug (3).
