4.4 DELIMBING A TREE
Figure 8
Make sure that there is nothing or nobody in the area
where the branches fall.
• Stand opposite the branch you will cut.
• Start to cut the higher branches.
• Then cut the lower branches.
• Cut downwards to prevent the bar from jamming.
4.5 LIMB TREE BRANCHES
Limbing is to remove the branches from a fallen tree.
Figure 8
1. Keep the larger lower branches to hold the log off
the ground.
2. Remove the small limbs in one cut.
3. Limb the branches with tension from the bottom to
up.
4. Keep the larger lower branches as a support until
the log is limbed.
5 MAINTENANCE
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.
Do not use strong solvents or detergents on the plastic
housing or components.
Remove the battery pack from the machine before
maintenance.

5.1 ADJUST THE CHAIN TENSION
Figure 9.11
Wear protective gloves if you touch the chain, bar or
areas around the chain.
1. Loosen the chain cover by turning the chain cover
knob counterclockwise.
It is not necessary to remove the chain cover to adjust
the chain tension.
2. Turn the chain tension screw behind the bar and
chain clockwise to increase the chain tension.
3. Turn the chain tension screw counterclockwise to
decrease the chain tension.
4. When the chain is at the wanted tension, tighten the
chain cover.
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 12-13.
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
