DRESSING A
GRINDING WHEEL
When dressing a grinding wheel use a suitable silicon carbide stick type dresser, as shown in Fig. 11. Bring the dresser forward on the tool rest until it just touches the high point of the face of the wheel and dress the wheel by moving the dresser back and forth. Repeat this operation until the face of the wheel is clean and the corners of the wheel are square.

GRINDING WHEELS
Use only grinding wheels that are rated higher than the
Two aluminum oxide grinding wheels are supplied with your grinder; one 36 grit and one 60 grit. For best grinding results, and to maintain good balance, always keep the wheels properly dressed. Do not force the work against a cold wheel. The grinding wheel should always be run at idle speed for one full minute before applying work. It is recommnended that only balanced wheels be used with your grinder. The use of balanced wheels adds years to the life of the bearings on the grinder and by eliminating the most common source of vibration, more accurate work is accomplished.
CHANGING WHEELS
When changing wheels, simply remove the screws attaching the side covers to the grinder and remove the side cover. To prevent shaft rotation, place a wedge between the grinding wheel and the wheel guard. Facing the grinder, turn the arbor nut down to loosen and up to tighten. IMPORTANT: DO NOT OVERTIGHTEN WHEEL NUTS WHEN INSTALLING
THE WHEELS.
