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 match 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 (H) 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 in the “+” direction
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 in the
“+” direction. 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 (Fig. 11h).
