HOW TO SHARPEN THE CUTTERS
See Figures 20 - 23.
WARNING:
Improper chain sharpening increases the potential of
kickback. Failure to replace or repair damaged chain can
cause serious injury.
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.
 Tighten the chain tension enough that the chain does not
wobble. Do all of your filing at the mid-point of the bar.
Wear gloves for protection.
 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.
Occasionally remove filings from the file with a wire brush.
NOTICE:
Dull or improperly sharpened chain can cause excessive
engine or motor speed during cutting, which may result
in severe engine or motor damage.
MAINTENANCE
ATTACHING THE STORAGE HANGER
See Figure 24.
There are two ways to hang the attachment for storage.
 To use the hanger cap, push in the button and place the
hanger cap over the end of the attachment shaft. Slightly
rotate the cap from side to side until the button locks into
place.
 The secondary hole in the attachment shaft can be used
for hanging purposes as well.
STORING THE ATTACHMENT
 Clean the attachment thoroughly and lubricate before
storing.
 Store the attachment indoors in a dry, well-ventilated
place that is inaccessible to children.
 Keep away from corrosive agents such as garden chemi-
cals and de-icing salts.
 Always place the scabbard on the cutting blade before
storing or when the attachment is not in use.
