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 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.
A slack chain may jump off and cause serious or even fatal
injury.
Wear protective gloves if you touch the chain, bar or areas
around the chain.
1. Stop the machine.
2. Loosen the sprocket cover nuts with the wrench.
It is not necessary to remove the sprocket cover to adjust the
chain tension.
3. Turn the chain tension adjuster clockwise to increase the
chain tension.
4. Turn the chain tension adjuster counterclockwise to
decrease the chain tension.
5. When the chain is at the wanted tension, tighten the
sprocket cover nuts.

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 your dealer, which has an electric
sharpener, perform important sharpening work.
Figure 16-19
1. Tensioning chain.
2. Sharpen the cutters corner with a 4.5 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.

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).
2. Clean the bar groove with the scraping hook (not
included).
3. Clean the lubrication holes.
4. Remove burr from the edges and level the cutters with a
flat file.
