INSTALLATION
Install the guide bar and saw chain
1. Position the chain saw power head on its side with the side cover facing upwards.
2. Turn the side cover knob anti-clockwise to remove the side cover and then loosen the
chain tensioning knob as much as possible.
(Fig. C)
3. Lay the new saw chain in a loop on a flat surface and straighten any kinks.
4. Place the chain drive links into the guide bar groove and make the chain a loop at the back
of the guide bar. The saw chain should face in the direction of chain rotation. If backwards,
turn the loop over.
(Fig. D)
5. Hold the chain in position on the guide bar and place the loop around the sprocket of the
power head. Make sure the bar hole fits well with bolt for saw chain tension.
(Fig. E)
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. F)
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. G)
- 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 2 mm out of the bar groove
(Fig. H)
.
NOTE:
New chains tend to stretch; check chain tension frequently and tension as required.
NOTE:
A chain tensioned while it is warm may be too tight upon cooling. Check the cold
tension before next use.
