Note: A new oil pump is installed in
model 064 saws from machine number
X 20 361 348. This new oil pump can
also be installed in older machines.
The adjustment range of the oil
quantity control bolt has been reduced
from 270 degrees (2 turns) to 90
degrees (1/4 turn).
- Take out the oil pump mounting
screws and remove the oil pump.
Note: On the 064 the oil delivery
hose has to be pulled off the oil
pump. For removal of the oil de-
livery hose it is necessary to press
out the sleeve in the bar mounting
flange. The hose is damaged in
this process and must be replaced.
Setting the oil pump to the Ematic
position "E" is the most economic
position under normal operating
conditions using a STIHL Ematic
guide bar.
Installation is a reversal of the
removal sequence.
