See «Technical Specifi cations» for the details which apply to
your chain. It is very diffi cult to fi le a chain saw correctly with-
out the proper aids. We recommend the use of a fi le guide to
ensure maximum cutting effi ciency with the least tendency to
kickback.
Filing cutters
To fi le cutters correctly, a ROUND FILE
and a FILE GUIDE are required. Look
under «Technical Specifi cations» for
the correct fi le diameter and fi le guide
for your saw and chain.
• File only with the chain
properly tensioned. A loose
chain wiggles, making it
diffi cult to fi le.
• Always fi le from the inside of each
cutter towards the outside. Lift
the fi le on the return stroke.
• File the cutters on one side fi rst.
Then turn the saw around and fi le
the cutters on the other side.
• Make certain that all cutters are of
equal length. When the horizontal
length is down to 3 mm (1/8”), the
chain is worn out and must be dis-
carded.
General instructions regarding cutters
• Never cut wood using a dull chain. Having to press hard is a
sure sign of a dull chain, as are very small chips. A very dull
chain will produce sawdust rather than chips.
• A sharp chain will produce large chips, and the saw will
feed itself through the wood.
• The part of the chain that saws is
called the CUTTING LINK, which
consists of a CUTTER (A) and
DEPTH GAUGE (B). The difference
in height between them determines
the depth of the cut.
• When fi ling a saw, pay close attention to:
TOP-PLATE ANGLE
CUTTING ANGLE
HORIZONTAL FILE ANGLE
FILE DIAMETER
FILE DEPTH
FILING CHAIN
CAUTION!
Improperly fi led cutters heighten
kickback tendencies!
LIMBING
CAUTION!
Most kickback accidents take place when limbing. Pay very close attention to the
kickback danger zone when cutting limbs under tension!
All the principles which apply to crosscutting also apply when cutting thick branches.
Cut complicated branches in several stages.
Ensure that your footing is secure at all times, whether moving about or
standing in one place. Always work with the log to your right. For best control,
hold the chain saw as close to your body as possible.
