ASSEMBLY

ASSEMBLING TOOL RESTS

1.Assemble adjustable tool rest (A) Fig. 3, to left side of tool rest arm (B), as shown, and fasten with one 5/16- 18x3/4" hex head screw and 3/8" lockwasher (C). Assemble the remaining tool rest to the right side of the other tool rest arm in the same manner. Do not com- pletely tighten hardware at this time.

2.Assemble left tool rest assembly (D) Fig. 4, to the inside of left wheel guard (E), and fasten with two 5/16-18x5/8" screws (F) and 3/8" flat washers (G) as shown.

3.Assemble right tool rest assembly to the inside of right wheel guard and fasten with two 5/16-18x5/8" hex head screws and 3/8" flat washers in the same manner.

4.Each tool rest assembly (D) Fig. 4, is adjustable so it can be positioned slightly below the centerline of the wheel and as close to the grinding wheel as possible, giving maximum support to the piece that is being ground. A distance of 1/8-inch or less between the grinding wheel and the inside edge of the tool rest should always be maintained. When the tool rest is posi- tioned correctly, tighten hardware (C) and (F). As the grinding wheel wears down to a smaller diameter, re- adjust the tool rest closer to the wheel. Freehand grind- ing without the use of a tool rest should always be done on the lower quarter of the wheel.

ASSEMBLING

SPARK GUARDS

Attach spark guard (A) Fig. 5, to each wheel guard, using the 1/4-20x1/4" hex head screw (B) and 1/4" washer (C) as shown. The spark guard (A) should be adjusted as close as possible to the grinding wheel so that sparks never strike the operator’s hand. As the wheels wear down, the spark guard (A) should be adjusted accord- ingly.
