SAFETY INSTRUCTIONS
Sharpening your chain and adjusting raker
clearance
It is very difficult to sharpen a chain correctly without the right
equipment. We recommend that you use our file gauge.This
will help you obtain the maximum kickback reduction and
cutting performance from your chain.
WARNING! The risk of kickback is increased
with a badly sharpened chain!
!
General information on sharpening cutting teeth
•
Never use a blunt chain.When the chain is blunt you have
to exert more pressure to force the bar through the wood
and the cuttings will be very small.If the chain is very blunt
it will not produce any cuttings at all.Wood powder would
be the only result.
See the Technical data section for information about
sharpening your chain.
WARNING! The following faults will increase
!
the risk of kickback considerably:
•
A sharp chain eats its way through the wood and
produces long, thick cuttings.
File angle too large
Cutting angle too small
•
The cutting part of the chain is called the cutting link and
this consists of a cutting tooth (A) and the raker lip (B).The
cutting depth is determined by the difference in height
between the two.
File diameter too small
Sharpening cutting teeth
When you sharpen a cutting tooth there are five important
factors to remember.
To sharpen cutting teeth you will need a round file and a file
gauge. See the Technical data section for information on the
size of file and gauge that are recommended for the chain
fitted to your chain saw.
1
Filing angle
•
•
Check that the chain is correctly tensioned. A slack chain
will move sideways, making it more difficult to sharpen
correctly.

3
Cutting angle
File position
Always file cutting teeth from the inside face. Reduce the
pressure on the return stroke.File all the teeth on one side
first, then turn the chain saw over and file the teeth on the
other side.

Round file diameter
File depth
•
File all the teeth to the same length. When the length of
the cutting teeth is reduced to 4 mm (0.16") the chain is
worn out and should be replaced.
