trigger lockout and the throttle
trigger (2); the Master Control
lever (1) jumps to the operating
position

and the engine begins to
idle
N
Pull the hand guard toward the
handlebar
The chain brake is released – the chain
saw is ready for use.

Switching off the engine
N

If the engine does not start
The starter grip may not have been
pulled briskly and forcefully enough; the
engine is probably flooded.

During the break-in period
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessarily high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
shortblock are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During work
Check chain tension frequently
A new saw chain must be retensioned
more frequently than one that has been
in use already for an extended period.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
but can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove on the underside of the bar –
Open the throttle only when the
chain brake is off. Increased
engine speeds with the chain
brake on (saw chain is stationary)
will quickly damage the clutch and
chain brake.

Operating Instructions
Open the throttle only when the
chain brake is off. Running the
engine at high revs with the chain
brake engaged (chain locked) will
quickly damage the engine and
chain drive (clutch, chain brake).
