Winter use
In winter, extreme cold and powdery snow can cause running
problems.
A
Assemble the remaining parts in reverse order.
Lift up the starter cord into the notch on the pulley. Tension the
return spring by turning the pulley clockwise about two turns.
NOTE!
Make sure that it is possible to turn the puliey at ieast 1/4 of
a turn further when the cord is fully pulled out.
The cylinder cover is prepared for extreme cold working conditions.
In the partition wall of the cover there is a hole, that is covered by a
cap (A) when operating at normal temperatures.
In case of extreme cold, this cap shall be removed so that heated
air from the cylinder can flow into the carburettor space and
prevent the air filter from being iced up.
NOTE!
Under normal temperature conditions the cap has to be
mounted. Otherwise there is a certain risk of overheating the
chain saw.
Adjusting the oil pump capacity
The oil pump is adjustable for four different capacities. Adjustment
is to be done after removal of chain, guide bar, clutch cover, centri­
fugal clutch and clutch drum.
With a screwdriver the oil capacity can be adjusted by turning the
screw. The index on the screw should face the capacity wanted.
Figure shows the position for capacity 2.
Recommended positions:
Bar 15": Pos. 2.
Bar 18" and more: Pos. 3-4.
Before assembling the clutch drum check that the washer between
drum and sealing ring is not lost.
