GENERAL SAFETY PRECAUTIONS
Bar
• Length (inches/cm)
• Number of teeth on bar tip sprocket (T).
• Chain pitch (inches). The spacing between the drive links
of the chain m
ust match the spacing of the teeth on the
bar tip sprocket and drive sprocket.
• Number of drive links. The number of drive links is
deter
mined by the length of the bar, the chain pitch and
the number of teeth on the bar tip sprocket.
• Bar groove width (inches/mm). The groove in the bar must
match the width of the chain dr
ive links.
• Chain oil hole and hole for chain tensioner. The bar must
be matched to the chain sa
w design.

Sharpening your chain and adjusting
depth gauge setting
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 chips will be very small. If the chain is very blunt
it will produce wood powder and no chips or shavings.
• A sharp chain eats its way through the wood and
produces long, thic
k chips or shavings.
• The cutting part of the chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge (B).
The cutters cutting depth is determined by the difference
in height between the two (depth gauge setting).
When you sharpen a cutting tooth there are four important
f
actors to remember.
1 Filing angle
2 Cutting angle
3 File position
4 Round file diameter
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.
See instructions under the heading Technical data for
inf
ormation about sharpening your chain.
!
WARNING! Departure from the sharpening
instructions considerably increases the risk
of kickback.
