Operation

FIG. 8

ACCESSORY ATTACHMENT

1.  Tilt motor back to expose the underside of the machine.
2.  Clean foreign material from magnet prior to tooling installation.
3.  Place the individual tooling segments into two or four of the magnetic pockets. Be 

careful around pinch points, as the tooling segments will snap into place as the 

magnetic connection is made (Figure 8). 

4.  For safety, depending on the condition of the surface being prepared, the individual 

tooling segments should be attached to the magnetic tooling holders using a single 

mounting screw for each segment.

Note: 

Use blanks in unused magnetic tooling pockets.

Attaching The Velcro Plate Adapter

The Velcro plate adapter attaches magnetically to the Magnetic tooling plate and snaps 

into place (Figure 9).

Mounting Brazed Diamond and Polishing Pads

The brazed diamond and polishing pads are attached to the Velcro adapter plates (Fig-

ures 10; 11).

Mounting PCD’s 

PCD’s are mounted to the holder (Figure 12) with tooling screws. The holder and PCD’s 

are not magnetic, but are attached to the magnetic plates. 

Note: 

When setting the machine down into the operating position, hold the machine 

firmly and set it down gently.
