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.
• 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 15 - 40 minutes.
Do not use dirty, used or contaminated oil. Damage can
occur to the bar or chain.
6 TRANSPORTATION AND
STORAGE
Before you move the machine, always
• Remove the battery pack from the machine.
• Keep hands clear of the lock-out button.
• Put the scabbard on the guide bar and the chain.
Before you put the machine into storage, always
• Remove all residual oil from the machine.
• Remove the battery pack from the machine.
• Clean all unwanted material from the machine.
• Make sure that the storage area is
