ADJUSTING THE CHAIN TENSION

1. Push the Rear Handle (1) until the Guide
Bar (7) is in the middle of the jaw opening
as shown. Lock the Guide Bar in the
middle position by inserting the Lock
Pin (12) into the Lock Pin Receptacle(13)
located under the Rear Handle (1) (See Fig.
B1 - B3).
2. Open the chain access cover (9) by using
the supplied wrench. To open turn the
Access Cover Nut no more than a 1/4 turn
in either direction. (See Fig. C)
3. Release tension on the Saw Chain (8) by
loosening the Chain Tensioning Bolt (10).
Turn the Chain Tensioning Bolt counter-
clockwise 2 or more times. (See Fig. D)
4. Add tension on the Saw Chain by turning
the Chain Tensioning Bolt clockwise. When
tightening the Chain Tensioning Bolt the
automatic chain tensioning system will set
the tension to the Saw Chain at the same

NOTE: It is not possible to overtighten the
Saw Chain, so tighten the chain as much

has been set. It should be possible to pull
the Saw Chain away from the side of the
Guide Bar approximately 3 mm and it
should snap back. (See Fig. E)
If tension is incorrect, repeat step 3,
ensuring the Guide Bar is free to move
when the tension is released.
