9. Install the chain cover.
10. Tighten the chain. Refer to Adjust the chain tension.
11. Tighten the chain cover knob when the chain is
correctly tensioned.
NOTE
If you start the chainsaw with a new chain, do a test
run for 2-3 minutes. A new chain gets longer after the
first use, examine the tension and tighten the chain if
necessary.
10.2 ADJUST THE CHAIN TENSION
Chains stretch with use. It is therefore important to
adjust the chain regularly to remove the slack.
Tension the chain so that it can only just be pulled away
from the bar at its center point.
WARNING
A slack chain may jump off and cause serious or even
fatal injury.
CAUTION
Wear protective gloves if you touch the chain, bar or
areas around the chain.
1. Stop the machine.
2. Loosen the chain cover by turning the chain tension
knob around at least two turns in a counterclockwise
direction.
NOTE
It is not necessary to remove the chain cover to adjust
the chain tension.
3. Turn the chain tension knob clockwise to tighten the
chain.
4. Pull the chain in the middle of the guide bar at the
bottom away from the bar. The gap between the
chain guide and the guide bar should be between 3
mm and 6 mm.
NOTE
During normal saw operation, the temperature of
the chain increases. The drive links of a correctly
tensioned warm chain will hang approximately 1/16 in.
(1.58 mm) out of the bar groove.
1/16 in. (1.58 mm)

Sharpen the cutters if chain does not go into wood
easily.
NOTE
We recommend that a service center, which has
an electric sharpener, perform important sharpening
work.
1. Tensioning chain.
