Starting the Grinder

WARNING:

Ensure the GRINDER is not locked ON before plugging it in. Check the SLIDE SWITCH (#19)

and make sure it is in the OFF position before plugging it into the power source.

Step 1: To turn the Grinder ON, push the Slide Switch (#19) forward with your thumb to the front position and the Grinder begins running.

Step 2: To turn the Grinder OFF, move the Slide Switch (#19) backward with your thumb to the rear position until the Grinder stops running.

Using the Grinder

When using the GRINDING WHEEL, hold the grinder at an angle of 10° to 15° relative to the work surface. When only the outer edge of the GRINDING WHEEL is used, a rough cut surface will result.

If the disc is pressed flat against the work, the grinding

action will be irregular or bumpy and the tool will be difficult to control.
