Oil lines
The oil screen 1 must be cleaned periodically.
The oil suction line 2 connects the oil tank and oil
pump.
When inserting the suction line into the hole in the
crankcase coat the collar with silicone paste
(980.007.100).
Note the position of the lug 3!
Then insert the angle nipple 4 and oil hose 5.
The oil pressure line 6 links the oil pump and the
guide bar connection.
Adjusting the supply rate
CAUTION: The adjustment range is smaller than
1/4 turn (70°)!
The oil supply rate is regulated with the adjusting
screw 7. The adjusting screw is on the bottom of the
housing.
The oil pump is factory adjusted to a medium supply
rate.
To change the setting, use a screwdriver (max. 5
mm tip) to turn the adjusting screw:
• Right for reduced oil supply
• Left for more oil supply
Even very small turns of adjusting screw 7 influence
the amount of oil supplied to the bar and chain.
