Sharpening The Saw Chain
WARNING:
Only sharpen the
saw chain yourself if you are trained
and have experience! Use proper tools
to sharpen the saw chain!
WARNING:
The saw chain is
very sharp. Always wear heavy-duty
protective gloves when handling or
performing maintenance on the saw
chain.
WARNING
：
An improperly
sharpened saw chain increases the
chance of kickback. Failure to replace or
properly maintain the saw chain can
cause serious injury.
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.
CAUTION:
A dull or
improperly sharpened saw chain can
cause excessive motor speed during
operation, which can result in severe
motor damage.
If the saw chain was damaged by
contacting hard objects, such as nails or
stones, or was abraded by mud or sand
on the wood, have an authorized
service center sharpen the saw chain.
When sharpening the saw chain, file all
cutters to the specified angles and
measurements. Other angles or
measurements can cause excessive
wear to the guide bar and saw chain,
cause the chain to dull quickly and
increase the chance of kickback. Fast
cutting can be obtained only when all
cutters are uniform.
1) Have the saw chain sharpened
professionally at an authorised
service centre or sharpen the chain
yourself by using a suitable
sharpening kit. Also observe the
sharpening instructions supplied
with the sharpening kit.
2) A file guide is available from most
reputable tool merchants and is the
easiest way to hold the file at the
correct position.
3) The height difference between the
tooth and the ridge is the cutting
depth. When sharpening the saw
chain you have to consider the
following points.
-File angle
-Cutting angle
-File position
-Diameter of round file
-File depth
