EN
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 lock nuts with the wrench.
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.

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.
WARNING
CAUTION
NOTE
NOTE
NOTE
English
• 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.
Replace the bar if:
• the groove is not fit with the height of the drive links
(which must never touch the bottom).
• the inside of the guide bar is worn and make the
chain lean to one side.
5.4 ADD THE BAR AND CHAIN
LUBRICANT
Examine the amount of oil in the machine. If the oil level
is low, add the bar and chain lubricant as follows.
Use bar and chain lubricant that is only for chains and
chain oilers.
The machine comes from the factory without bar and
chain lubricant.
1. Loosen and remove the cap from the oil tank.
2. Put the oil into the oil tank.
3. Monitor the oil indicator to make sure that no dirt in
the oil tank while you add the oil.
4. Put the oil cap on.
5. Tighten the oil cap.
6. The whole oil tank will last for 20- 40 minutes.
Do not use dirty, used or contaminated oil. Damage
can occur to the bar or chain.
