Each can be positioned slightly below the center-

line of the wheel and as close to the grinding

wheel as possible, giving maximum support to

the workpiece. Maintain a distance of 1/8" or less

between the grinding wheel and the inside edge of

the tool rest. Adjust the tool rest when the grinding

wheel wears down. When the tool rest is positioned

correctly, tighten the hardware, (C) and (F) Fig. 2.

Freehand grinding without the use of a tool rest

should always be done on the lower quarter of the

wheel.

Spark guards

The spark guard (A) Fig. 3 is mounted to the side of each wheel guard, using a 1/4-20 x 1/4" hex head screw (B) Fig. 3 and a 1/4" flat washer (C).

NOTE: The tab (D) Fig. 3 on the side of the spark guard

(A)must be placed in slot (E), before attaching the spark guard (A) to the grinder.

Adjust the spark guard (A) as close as possible to the

 

grinding wheel so that sparks never strike the operator’s

 

hand. As the wheels wear down, adjust the spark guard

 

(A) accordingly.
