5. Check the guide bar ‘rail’ for wear: Hold a ruler (straight edge) against the
side of the guide bar and ‘cutter side plates’. If there is a gap between the
ruler and guide bar the guide bar ‘rail’ is normal. If there is no gap (ruler flush
against the side of the guide bar) the guide bar ‘rail’ is worn and needs to be
replaced with a new one of the same type (Fig. 46).
6. Check the saw chain for possible wear and damages. Replace it with a new
one if required. Experienced user can sharpen a dull saw chain (see section
“Saw chain sharpening” below).
7. Refit the saw chain (20) and the guide bar (19) as described under “Assembly”.
Saw chain sharpening
1. Have the saw chain (20) sharpened professionally at an authorised service
centre or sharpen the chain yourself by using a proper sharpening kit. Also
observe the sharpening instructions supplied with the sharpening kit.
2. The height difference between the
tooth and the ridge is the cutting
depth. When sharpening the saw
chain (20) you have to consider
the following points (Fig. 47).
-- File angle
-- Cutting angle
-- File position
-- Diameter of round file
-- File depth
NOTE:
Never saw with a blunt chain. The saw chain is blunt if you
have to push the product into the tree and the chips are very small.
WARNING!
Only sharpen the saw chain yourself if you are trained
and have experience! Use proper tools to sharpen the saw chain!
