NOTE
Do not let the chain touch the ground.
When bucking is complete,
1. Release the trigger.
2. Stop the chainsaw fully.
3. Move the chainsaw from tree to tree.
5 MAINTENANCE
CAUTION
Do not let brake fluids, gasoline, petroleum-based
materials touch the plastic parts. Chemicals can
cause damage to the plastic, and make the plastic
unserviceable.
CAUTION
Do not use strong solvents or detergents on the plastic
housing or components.
WARNING
Remove the battery pack from the machine before
maintenance.
5.1 ADJUST THE CHAIN TENSION
Figure 2-7.
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 as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
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 cover
knob counterclockwise.
NOTE
It is not necessary to remove the chain cover to adjust
the chain tension.
3. Turn the chain tension knob clockwise to increase
the chain tension.
4. Turn the chain tension knob counterclockwise to
decrease the chain tension.
English
5. When the chain is at the wanted tension, tighten the
chain cover.
6. 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 4 mm.
5.2 SHARPEN THE CUTTERS
Sharpen the cutters if it is not easy for the chain to go
into the wood.
We recommend that a service center, which has
an electric sharpener, perform important sharpening
work.
Figure 16-19.
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.
4. File all the cutters to the specified angles and the
same length.
During the process,
• Keep the file flat with the surface to be sharpened.
• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the
surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to
the other side.
Replace the chain if:
• The length of the cutting edges is less than 5 mm.
• There is too much space between the drive links
and the rivets.
• The cut speed is slow
• Sharpening the chain many times but it does not
increase the cutting speed. The chain is worn.
5.3 GUIDE BAR MAINTENANCE
Figure 20-21.
Make sure that it is turned over periodically to keep
symmetrical wear on the bar.
1. Lubricate the bearings on the nose sprocket (if
present) with the syringe (not included).
