CARE AND MAINTENANCE
NOTICE:
Small directional arrows are engraved in
the saw chain. Another directional arrow is molded
into the housing. When looping the saw chain onto
the sprocket, make sure that the direction of the
arrows on the saw chain will correspond to the
direction of the arrow on the housing. If they face
in opposite directions, turn over the saw chain and
guide bar assembly.
e. Place the guide bar on the mounting surface
by sliding the guide bar slot over the alignment
flanges, making sure that the tension-adjusting
pin is inserted in the lower hole in the tail of the
bar (Fig. 11e).
f. Replace the side cover and lightly tighten the
side cover knob by turning it clockwise. The bar
must be free to move for tension adjustment
(Fig. 11f).
NOTICE:
To extend the guide bar life, invert the bar
occasionally.
CAUTION
• The saw chain must be properly tensioned
before using.
g. Remove all the slack from the chain by turning
the chain-tensioning knob clockwise until the
chain seats snugly against the guide bar with
the drive links in the guide bar groove.
h. Lift the tip of the guide bar up to check for sag
(Fig. 11g). Release the tip of the guide bar and
turn the chain-tensioning knob once clockwise.
Repeat this process until the sag is eliminated.
i. Hold the tip of the guide bar up and tighten
the side cover knob securely. The chain is
correctly tensioned when there is no sag on
the underside of the guide bar and the chain
is snug, but it can be turned by hand without
binding.
NOTICE:
If chain is too tight, it will not rotate.
Loosen the side cover knob slightly and turn the
tensioning knob once to the “
-
” direction. Lift the
tip of the guide bar up and retighten the side cover
knob securely. Assure that the chain will rotate
without binding.
