Operating Instructions

During the 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
unnecessarily 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
shortblock are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During work
CAUTION
Always work with water.
CAUTION
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
The diamond abrasive chain stretches
and begins to sag. The drive links on the
underside of the bar must not come out
of the bar groove by more than 15 mm –
the diamond abrasive chain may
otherwise jump off the bar – retension
the diamond abrasive chain – see
"Tensioning the diamond abrasive
chain".
