MAINTENANCE
For smooth and fast cutting, chain needs to
be maintained properly. The chain requires
sharpening when the wood chips are small and
powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side.
During maintenance of your chain, consider the
following:
 Improper filing angle of the side plate can in-
crease the risk of a severe kickback.
 Raker (depth gauge) clearance.
Too low increases the potential for kickback.

Not low enough decreases cutting ability.

 If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen
chain.
NOTE: Inspect the drive sprocket for wear or
damage when replacing the chain. If signs of wear
or damage are present in the areas indicated, have
the drive sprocket replaced by an authorized dealer.
HOW TO SHARPEN THE CUTTERS
See Figures 36 - 37.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
WARNING:
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain to prevent serious personal injury.
 Properly tension the chain prior to sharpening.
Refer to Chain Tension section earlier in this
manual. Do all of your filing at the mid-point of
the bar.
 Use a 5/32 in. diameter round file and holder.
 Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
 Using light but firm pressure, stroke towards
the front corner of the tooth.
 Lift file away from the steel on each return
stroke.
 Put a few firm strokes on every tooth. File all
left hand cutters in one direction. Then move
to the other side and file the right hand cutters
in the opposite direction.
 Remove filings from the file with a wire brush.

WARNING:
Improper chain sharpening increases the
potential of kickback, which can result in
serious personal injury.
WARNING:
Failure to replace or repair damaged chain can
cause serious injury.
NOTICE:
A dull or improperly sharpened chain can cause
excessive motor speed during cutting which
may result in severe motor damage.
TOP PLATE FILING ANGLE
See Figure 38.
 CORRECT 30° - File holders are marked with
guide marks to align file properly to produce
correct top plate angle.
 LESS THAN 30° - For Cross Cutting.
 MORE THAN 30° - Feathered Edge Dulls
Quickly.
