Cleaning the guide bar,
lubricating the sprocket nose
CAUTION: Protective gloves must be worn.
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to lubricate
the return sprocket bearings regularly (once a week). To do
this, first
thoroughly
clean the 0.08" (2 mm) hole at the tip of
the guide bar, and then press in a small amount of multi-
purpose grease.
Multi-purpose grease and grease guns are available as
accessories.
