Operating Instructions
Throttle cable adjustment
During break-in period
Cold chain
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand.
Retension if necessary –
see chapter "Tensioning the Saw
Chain".
:
Check adjustment of throttle cable –
see "Adjusting the Throttle Cable".
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessary 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
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
Tank run until dry
:
After refueling, press the fuel pump
bulb at least five times – even if bulb
is filled with fuel.
Chain at operating temperature
:
:
Set choke knob according to engine
temperature.
The chain stretches and begins to sag.
The drive links on the underside of the
bar must not come out of the bar groove
Now start the engine.
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see chapter "Adjusting the
Carburetor".
–
the chain may otherwise jump off the
bar.
Retension the chain –
see chapter "Tensioning the Saw
Chain".
Always slacken off the chain again
after finishing work. The chain
contracts as it cools down. If it is not
slackened off, it may damage the
crankshaft and bearings.
During operation
Check chain tension frequently!
A new chain has to be tensioned more
often than one that has been in use for
some time.
