Dressing the Grinding Wheel
New grinding wheels frequently are not true and during operation will often become
grooved, glazed (build up), out of round, or misshapen. You will need a grinding wheel
dresser (not provided) for this operation. Dressers are available from Harbor Freight Tools.
To dress the grinding wheel:
1. Stand to the side of the wheel for this operation.
2. If the grinding wheel is new, let it run for a minute with no load. If the grinding wheel
runs straight and true, you will not need to dress it prior to operation. If it does not,
proceed with the following instructions.
3. If you are using a “pistol grip” dresser, grip the handle firmly with one hand and the
arm of the dresser with the other. Allow the wheel to reach full speed. Use the tool
rest to support your hand and the dresser, and evenly apply the dresser to all surfaces
of the wheel. The wheel can be dressed in a few minutes.
4. If you are using an “in-line” dresser, hold the handle firmly, put the dresser on the tool
rest so that its wheels can move freely (i.e., the exposed part of the wheel should be
facing up). Let the wheel reach full speed and apply the dresser evenly to all surfaces.
Changing Grinding Wheels
1. Unplug the Bench Grinder from the electrical outlet.
2. Remove three Screws holding the Cover (2). Set aside Cover and Screws.
3. Loosen Hex Screw (18) and move the Eye Shield above the Grinding Wheel.
4. Remove the Tool Rest from the Wheel Guard (7) by removing Bolt (21) and Washer
(20).
5. While holding the Motor Rotor (14) in place with a large, flat blade screwdriver,
turn the Nut (3) clockwise to loosen and remove Grinding Wheel and Flange (4). If
removing the right Grinding Wheel, turn the Nut (3) counterclockwise to loosen and
remove.
6. Replace Grinding Wheel with a new one rated to run to at least to the maximum
speed of the Bench Grinder. See Grinding Wheel Specifications on page 2. Securely
tighten Nut (3).
CAUTION: Using a Grinding Wheel
not rated to run at least to 3450
RPM could cause it to fly apart,
causing injury, or damage to the
Bench Grinder.
