9. Maintenance
English
• Before cleaning, inspecting, or repairing the unit,
make sure that the engine has stopped and is
cool.
• Use protective gloves whenever inspecting,
removing, sharpening, and installing the blades.
■ BLADE
Wipe off dust and dirt attached to the blades, and oil
them after every use.
To Sharpen blade:
1. When the cutting edges have become dull, sharpen
them by using a small disk grinder. (MA1-a)
2. When sharpening, offset the teeth of upper and
lower blades by 3mm. (MA1-b) To offset, insert the
hexagon wrench into the socket on the top of the
cuttercase and rotate it. (MA2)
• Replace with new blades when the tooth width
became less than 8mm at the tip. (MA1-c)
• As the extent of wear differs by each tooth
depending on use conditions, rotate the blade
position at intervals.
To remove blades:
1. Turn over the machine and remove the bottom cover
(MA3-1) by removing the 4 screws.
2. Loosen 4 screws and remove the lower blade (MA3-
2)
3. Loosen 4 screws and remove the upper blade (MA3-
3),
To install blades:
The upper and lower blades are interchangeable.
When fastening the blade mounting screws, torque
them uniformly.
