OPERATING THE GRINDER

WARNING

●Keep your face away from the tip tool during use.

●Wear goggles and a dust mask when using the grinder. Breakage of the tip tool may lead to injury.

●Do not operate the grinder at extremely slow speed. A smooth finished surface will not be achieved and doing so may lead to damage of the tip tool, breakdown of the grinder or injury.

CAUTION

Do not touch the tip tool, collet nut or collet immediately after machining as they will be very hot and touching them may result in burns.

1.Remove the battery and attach the tip tool

2.Fix the workpiece so that it does not move

The smaller the workpiece, the more unstable it is to machine. Fix small workpieces in a vise. Holding the workpiece by hand may result in injury.

3.Insert the battery in the grinder

4.Check the balance of the tip tool

Check the tip tool visually at low speed (around [1] on the switch dial).

Also check for abnormal noise during operation.

5. Select the machining speed

○Select the optimal speed for the material while performing trial grinding with reference to Table 5.

○If plastic is machined at high speed, it may melt due to heating. Test it gradually starting from a low speed.
