5. Hold the chain in position on the guide bar
and place the loop around the sprocket of
the power head. (Fig. 12)

6. Slide the guide bar slot over the alignment
flanges until the tension adjusting pin is
inserted in the lower hole in the tail of the
bar.
NOTE:
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.
7. Replace the side cover and slightly tighten
the side cover knob.(Fig. 13)
Fig.13
8. Lift the tip of the guide bar up to check for
sag. Release the tip of the guide bar and
turn the chain tensioning knob clockwise.
Repeat this process until the sag is
eliminated.
9. Tighten the side cover knob securely to
ensure that the saw chain is properly
tensioned before using.
NOTE:
If chain is too tight, it will not rotate.
Loosen the side cover knob slightly and turn the
tensioning knob once from right to left. Lift the tip
of the guide bar up and retighten the side cover
knob securely. Assure that the chain will rotate
without binding.
Adjusting the chain tension
- Stop the motor and remove the battery pack
before adjusting the chain tension. Make
sure the side cover knob is loosened. Turn
the chain tensioning knob clockwise to
tension the chain. (Fig. 14)

- A cold chain is correctly tensioned when
there is no slack on the underside of the
guide bar and the chain is snug, but it can
be turned by hand without binding. The
chain must be re-tensioned whenever the
flats on the drive links do not sit in the bar
groove.
- During normal saw operation, the
temperature of the chain will increase. The
drive links of a correctly tensioned warm
chain will hang approximately 0.08" (2 mm)
out of the bar groove (Fig. 15).
