17.8 Stopping the engine
4
► Move the Master Control lever in the direction
of STOP or † – when released, the Master
Control lever springs back to the normal run
position F.
17.9 If the engine does not start
► Check that all settings are correct.
► Check that there is fuel in the tank and refuel if
necessary.
► Check that the spark plug boot is properly con‐
nected.
► Repeat the starting procedure.
or:
It is possible that the fuel-air mixture in the com‐
bustion chamber is over-rich and has flooded the
engine.
► Remove the spark plug – see "Spark Plug".
► Dry the spark plug.
► Hold the saw on the ground.
► Push the Master Control lever as far as stop in
direction of STOP or † and hold it there.
WARNING
An ignition spark may occur if the Master Control
lever is not held against STOP or †.
► Operate the rewind starter several times.
► Release the Master Control lever – it springs
back to the run position F.
► Install the spark plug – see "Spark Plug".
► Hold and start your saw as described.

18 Operating Instructions

18.1 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 dur‐
ing 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
26
this period. The engine develops its maximum
power after about 5 to 15 tank fillings.
STOP
18.2
NOTICE
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).
18.2.1
A new saw chain must be retensioned more fre‐
quently than one that has been in use already for
an extended period.
18.2.2
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 neces‐
sary – see "Tensioning the Saw Chain".
18.2.3
The chain stretches and begins to sag. The drive
links must not come out of the bar groove on the
underside of the bar – the chain may otherwise
jump off the bar. Retension the chain – see "Ten‐
sioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it is not
slackened off, it can damage the crankshaft and
bearings.
18.2.4
After a long period of full-throttle operation, allow
engine to run for a while at idle speed so that the
heat in the engine can be dissipated by flow of
cooling air. This protects engine-mounted com‐
ponents (ignition, carburetor) from thermal over‐
load.
18.3
► Slacken off the chain if you have retensioned it
at operating temperature during work.
