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.

•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.
