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. (a)
2. When sharpening, offset the teeth of upper and lower
blades by 3mm. (b) To offset, insert the hexagon
wrench into the socket on the top of the cuttercase
and rotate it.
• 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.
• Replace with new blades when the tooth width be-
came less than 8mm at the tip. (c)
• As the extent of wear differs by each tooth depend-
ing on use conditions, rotate the blade position at in-
tervals.
To remove blades:
1. Turn over the machine and remove the bottom cover
(1) by removing the 4 screws.
2. Loosen 4 screws and remove the lower blade (2)
3. Loosen 4 screws and remove the upper blade (3).
To install blades:
The upper and lower blades are interchangeable. When
fastening the blade mounting screws, torque them uni-
formly.
