Adjusting the oil pump capacity
Heated handles
The handle heating is regulated by a thermostat which means that
the handles always have the right temperature for the hands.
The wirings are fed from a generator in the ignition system. The
power of the heating system is 76 watts at 8.500 rpm. The tempe-
rature of the handles at different outer temperatures could be seen
in the diagram.

Winter use
In winter, extreme cold and powdery snow can cause running
problems.
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.
The cylinder cover is prepared for extreme cold working conditions.
In the ~artition wall of the cover there is a hole, that is covered bv 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 carburetor space and
prevent the air filter from being iced up.

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.
NOTE!
Under normal temperature conditions the cap has to be
mounted. Otherwise there is a certain risk of overheating the
chain saw.
Before assembling the clutch drum check that the washer between
drum and sealing ring is not lost.
