During Break- in Period
During Operation
After Finishing Work
•
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.
Check chain tension frequently.
A new chain has to be retensioned more
often than one that has been in use for
some time.
Slacken off the chain if you have
retensioned it at operating
temperature during cutting work.
The chain contracts as it cools down.
If it is not slackened off, it could damage
the crankshaft and bearings.
Chain cold:
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.
Tension is correct when chain fits snugly
against the underside of the bar and can
still be pulled along the bar by hand.
Retension if necessary -
Before storing your saw
for a long period -
see section “Tensioning the Saw Chain”.
See chapter “Storing the machine”.
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.
Do not make the mixture leaner to
achieve an apparent increase in
power - this could damage the engine
-
see section “Adjusting Carburetor”.
Retension the chain -
see section “Tensioning the Saw Chain”.
Important: Always disengage the
chain brake before opening the
throttle. Running the engine at higher
revs with the chain brake engaged
(saw chain at a standstill) will quickly
damage the engine and chain drive
(clutch, chain brake).
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 crankshaft and bearings.
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 flow of cooling air.
This protects engine-mounted compo-
nents (ignition, carburetor) from
thermal overload.
