The chain brake should snap into both
positions.If strong resistance is felt or lever
does not move into either position, DO NOT
USE YOUR SAW.
Take it immediately to an authorized servicing
dealer.
3 CHAIN CATCHER
This unit is fitted with a chain catcher below the
drive spocket. This is intended to stop the
rearward movement of th chain in case of
breakage or if it should come out of the bar, It
should never be removed.
CHAIN SHARPENING
1 The cutter teeth should be sharpened with a
round 7/32" file.
The job can be made easier by also using a file
holder.
The chain can remain fitted on the bar during
sharpening.
Before commencing, the chain should be
tensioned correctly and the chain brake should
be activated to prevent the chain from moving.
2 To obtain a correct sharpening the file must be
carefully held to maintain 3 basic angles:
A Top angle 30 ° - 35 °
B External,side angle 85 ° - 90 °
C Internal, side angle 60 °.
File in one direction only, from the inside of
the cutter tooth towards the outside.
Do not allow the file to touch the chain as you
bring it back to re-position it. Each cutter tooth
should be filed with the same number of strokes.
3 The file should be held horizontally to the cutter
tooth being sharpened.
4 Best results to obtain a precise sideways
angle can be obtained by holding the file so
that it rises 0,5 mm above the top face of the
cutter tooth.
5 DEPTH GAUGE
Correct depth gauge height is vital to ensure
maximum chain life and cutting efficiency.
The height of the depth gauge should be
lowered as the cutter tooth is filed back; this
height should be checked every 4 or 5
sharpenings.
The best way to do this is to use a flat file and
a depth gauge tool.
The correct setting is 0.65 mm below the top
edge of the cutter tooth.
The cutter tooth depth gauge should then be
rounded (D).
Engine still gives trouble: contact your dealer.
