ASSEMBLY

WARNING: FOR YOUR OWN SAFETY, DO NOT CONNECT THE TOOL TO THE POWER SOURCE UNTIL THE

MACHINE IS COMPLETELY ASSEMBLED AND YOU READ AND UNDERSTAND THE ENTIRE INSTRUCTION

MANUAL.

TOOL RESTS

1. Assemble left tool rest (A) Fig. 3, to left tool rest arm

(B), as shown, and fasten with one 5/16-18x3/4" knob

tool rest in the same manner. Do not completely 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 5/16" 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 5/16" 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. Always maintain a distance of 1/8" or less

between the grinding wheel and the inside edge of the

tool rest. As the wheels wear down, the tool rest should

be adjusted accordingly. When the tool rest is positioned

correctly, tighten hardware (C) and (F). 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. 5, is mounted to the side of each

wheel guard, using a 1/4-20x1/4" hex head screw (B)

and 1/4" flat washer (C) as shown. NOTE: The tab (D)

Fig. 5, on the side of the spark guard (A), must be

placed in slot (E), before attaching the spark guard

(A) to the grinder. 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 accordingly.

EYE SHIELDS

Your grinder is supplied with two eye shields for operator

protection.

WARNING: ALWAYS WEAR EYE PROTECTION. To

assemble the eye shields, proceed as follows:

1. Place the eye shield (A) on the spark guard as shown

in Fig. 6.
