2. GRINDING PROCESS

1. Grinding pressure

Apply only a little pressure to grinding disk.

Excessive pressure on the grinding disk will

decrease grinding speed and cause a rough

surface finish and may cause overheating of the

motor and machine failure.

2. Grinding angle

Do not apply the total surface of the grinding

disk to work material. Efficient grinding is

achieved by keeping the angle between cutting

blade and work material at 15° to 30° as shown

in the picture.

3. CAUTION AFTER USE

Immediately turn off the machine after finishing

your work and store it in a safe place. Do not let

the machine run freely in a dust filled space.

Dust may end up in the motor and cause dama-

ges.

Grinding disks may damage on impact. Always

inspect grinding disks after impact and replace

when damaged.
