SYMPTOMS

Grinder won't start

Excessive vibration

Grooved wheel

Motor is overheating

MOUNTING THE DGP-3

The DGP-3 stand alone grinder (without vacuum system and cabinet) should be mounted to a solid horizontal surface

(mounting hardware is not provided).

If mounted to a metal cabinet or pedestal, align the mounting holes with the corresponding holes in the cabinet or

pedestal. Insert a 1/4"-20 X 1 1/4" hex head bolt with flat washer beneath the head of the grinder. From the bottom of

the cabinet or pedestal, place a 1/4" flat washer and 1/4"-20 hex nut onto the bolt extension. Tighten only until the space

between the grinder base and the cabinet or pedestal is 1/8". Using a second nut on each bolt, tighten against the first

to prevent loosening by vibration.

If mounted to a wooden bench top, use 1/4" wood screws that are 1-1/4" long with flat washer beneath the heads.

Tighten screws until the space between the grinder base and the bench is 1/8".

ELECTRODE GRINDING ASSEMBLY

THE BASICS

The Electrode Grinding Assembly is attached to the right wheel housing (refer to Figure 1 for the general arrangement of

the assembly). It provides the means to support an electrode in a fixed position relative to the diamond-grinding surface

through an electrode guide collet that matches the electrode diameter. The electrode is brought into gentle contact with

the diamond-grinding surface and at the same time is rotated slowly in one direction between the operator's thumb and

forefinger. As an alternative, pin vises are also provided to hold the tungsten during rotation. Note: all positioning and

adjustement should be made before turning on the grinder.
