INSTALLING THE GUIDE BAR AND SAW CHAIN
1. Loosen the locking knob counter clockwise and remove the
sprocket cover
2. The adjust block should already be attached to the guide bar. Make sure
the adjust block is turned all the way counter-clockwise and then put the
saw chain on the guide bar.
3. Place the guide bar onto the bar studs and the chain around the sprocket.
Make sure the chain cutters on top of the guide bar face in the direction
that the chain runs. See below picture.
4. Install the sprocket cover by turning the locking knob clockwise. Don’t tighten it before adjusting
chain tension.
5. Adjust the chain tension by turning the tension wheel clockwise. The chain is
correctly tensioned when it is still possible to raise it by 2-3 mm in the middle of
the guide bar.
6. Tighten the sprocket cover by turning the locking knob clockwise.
Caution: Proper saw chain tension is extremely important. If saw chain is too tight, the guide
bar and saw chain will be quickly damaged. If the saw chain is too loose, it may get out of
the guide bar groove and cause an injury.
Note: A new chain will stretch so adjust the tension after a few cuts. Watch saw chain tension
carefully for the first half hour of cutting.
WarnInG - Check the chain tension before each use.
always use protective gloves.
WarnInG - never try to run the chainsaw without sprocket
cover securely tightened.
