Tool Rests; Spark Guards; Eye Shields - Delta GR450 Instruction Manual

For your own safety, do not connect the machine to the power source until the machine is
completely assembled and you read and understand the entire instruction manual.

TOOL RESTS

1. Attach the adjustable tool rest (A) Fig. 1 to the left
side of the tool rest arm (B), and fasten with one
5/16-18x3/4" hex head screw (C) and 5/16"
lockwasher (D). Attach the remaining tool rest to
the right side of the tool. Loosely tighten the
hardware for further adjustment.
2. Attach the left tool rest assembly (D) Fig. 2 to the
inside of the left wheel guard (E), and fasten with
two 5/16-18x5/8" screws (F) and 3/4" flat washers
(G).
3. Attach the right tool rest assembly to the inside of
the right wheel guard and fasten with two 5/16-
18x5/8" hex head screws and 3/4" flat washers.
4. Each tool rest assembly (D) Fig. 4 is adjustable so
that it 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 1/4-20x1/4" 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.
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 shields to protect your
eyes.
ALWAYS WEAR EYE PROTECTION.
To attach the eye shields:
1. Place the eye shield (A) Fig. 4 on the spark guard.
