Storage
When the guide bar shows signs of wear, turn it over
on the saw to distribute the wear for maximum bar
life. Feathering or burring of the bar rails is a normal
process of bar wear. You should smooth such faults
with a file as soon as they occur.
Replace a bar with any of the following faults:
·
wear inside the bar rails permitting the chain to lay
over sideways
·
bent guide bar
·
cracked or broken rails
·
spread rails
Turn the saw over, check the underside of the guide
bar, and make sure that the lubrication holes and
chain groove are free from impurities.
Guide Bar Maintenance
·
To move the chain forward, use a screwdriver.
·
Turn the bar over in the vice and repeat on all the
other cutting edges.
·
Check that the depth limiter tooth does not stick
out farther than the inspection tool and file any
projecting parts with a flat file, rounding off the
edges.
·
After sharpening, remove all traces of filing and
dust and lubricate the chain in an oil bath. Replace
the chain whenever:
– the length of the cutting edges decreases to 5
mm or less;
– there is too much play between the links and the
rivets.
