Adjusting the pump feed rate
The pump feed rate is adjusted with the adjuster screw (E).
The table (right) shows the number of turns from the home
position for respective bar lengths. The table applies to
Jonsered chain oil.
If a different oil is used the screw should be unscrewed an
additional turn in the first two cases.
Assembly
1. Insert the suction pipe (C) in the hole in the crankcase.
See fig. 3 page 28.
2. Place the spring (I), 2 washers (J) and pump piston (H)
in the pump housing. Oil in all parts with chain oil.
See fig. 4 page 28.
3. Use a screwdriver to press in the pump piston and
