Adjustment of pump feed rate
The pump feed rate is adjusted with the adjustment screw
(E). The table (right) shows the number of turns outward
from fully home, required for different lengths of guide bar.
The table applies to Jonsered chain oil. If another chain
oil is used, the adjuster should be turned one extra turn
outward in the first three cases.
