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 Operation Do not make the mixture leaner to achieve an apparent increase in power - this could damage the engine - see "Adjusting the Carburetor". 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".

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 Operation
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".
Operating Instructions
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see "Adjusting the
Carburetor".
