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.

1RWH Always disengage chain brake
before accelerating engine and before
starting cutting work. High revs with the
chain brake engaged (chain locked) will
quickly damage the powerhead and
chain drive (clutch, chain brake).

A new chain has to be retensioned more
often than one that has been in use for
some time.
&KDLQFROG
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 -
see section "Tensioning the Saw Chain".
&KDLQDWRSHUDWLQJWHPSHUDWXUH
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 section "Tensioning the Saw Chain".
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.

Allow engine to run for a short while
at idling speed so that engine heat can
be dissipated by flow of cooling air.
This protects engine-mounted compo-
nents (ignition, carburetor) from thermal
overload.

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.
