Operating Instructions
During 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 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.
During break-in period:
Do not make the mixture leaner to achieve an apparent increase in power – this could damage the
engine.
●
Check chain tension frequently:
A new chain has to be retensioned more often than one that has been
in use for some time.
●
Chain cold:
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"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 – the chain may otherwise jump off the bar. Retension the chain –see
"Tensioning the Saw Chain".
●
After long period of full-throttle operation: Allow engine to run for a short
while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects
engine-mounted components (ignition, carburetor) from thermal overload.
The chain contracts as it cools down. If it is not slackened off, it can damage the gear shaft and bearings.
After Finishing Work:
●
Slacken off the chain if you have retensioned it at operating temperature during cutting work.
●
Storing
your saw for a short period Wait for the engine to cool down. Drain the fuel tank. Store the machine in a dry
location. Check the tightness of all accessible screws and nuts (not adjusting screws) at regular intervals and
retighten if necessary.
●
Storing for a long period See chapter on "Storing the Machine"
Always slacken off the chain after finishing work. The chain contracts as it cools down. If it is not
slackened off, it can damage the gear shaft and bearings.
