WARNING:
Shut off engine before attempting to adjust
the chain tension. Additionally, disconnect the spark
plug wire. Wear gloves when handling chains to
prevent injury.
To adjust the tension:
1.
Loosen the bar nuts using the Combi-wrench.
2.
Turn the tension screw clockwise (Fig. 30, 1) until
'the chain touches and no longer sags at the
underside of the bar.
FIGURE 30
3.
The saw chain is correctly tensioned when the
chain fits snuggly against the underside of the bar,
but can still be easily rotated on the bar by hand.
Be sure the chain fits correctly on the sprocket and
the bar (Fig. 30). NOTE: The chain will not rotate if
the chain brake is engaged.
4.
Hold up the bar tip. Tighten the bar nuts securely
with the Combi-wrench provided. Only use the
provided Combi-wrench to tighten the bar nuts
(Fig. 31). CAUTION: Excessive force will strip the
bar studs out of the saw case.

Feed the chain around the chain sprocket into the
bar groove (Fig. 35). Cutters (the sharp edge on
top) must point forward toward bar nose. Insure
the chain drive links engage the chain sprocket
and the sprocket nose on the bar.

Attach the side cover and bar nuts by hand
tightening only. Lifting the bar nose slightly; turn
the chain clockwise and tighten the chain with the
tension screw until the chain touches the bar
without sagging. The chain tension is correct if the
chain is snug against the underside of the bar but
can still be easily rotated by hand. NOTE: The
chain will not rotate if the chain brake is engaged!
