11.1 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 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.
11.2 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 18-21.
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.
English (Original Instructions)
NOTE
NOTE
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.
11.3 GUIDE BAR MAINTENANCE
Figure 22.
Make sure that it is turned over periodically to keep
symmetrical wear on the bar.
1. Clear the groove of the guide bar with a small screw-
driver, for example.
2. Clean the lubrication holes.
3. 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.
12 TRANSPORTATION AND
STORAGE
Before you move the machine, always
• Remove the battery pack from the machine.
• Keep hands clear of the trigger switch lockout.
• Put the guide bar cover 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
• Not available to children.
• Away from agents which can cause corrosion, such as
garden chemicals and de-icing salts.
