11. Tighten the nuts when the chain is correctly tensioned.
NOTE
If you start the chain saw with a new chain, have a test 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
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up the
slack.
Tension the chain so that it can only just be pulled away from
the bar at its centre 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 lock nuts with the wrench.
NOTE
It is not necessary to remove the chain cover to adjust the
chain tension.
3. Turn the chain adjustment screw clockwise to increase
the chain tension.
4. Turn the chain adjustment screw counterclockwise to
decrease the chain tension.
5. When the chain is at the wanted tension, tighten the lock
nuts.
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)
10.3 SHARPEN THE CUTTERS
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.
2. Sharpen the cutters corner with a 5/32 in. (4 mm)
diameter round file .
3. Sharpen the top plate, side plate and depth gauge with a
flat file.
