Flexible Lamp, Starting and Stopping Grinder

FLEXIBLE LAMP

If you purchased the Model 23-645, the flexible lamp op- erates independently of the grinder. To turn the lamp on and off, rotate switch (A) Fig. 13.

WARNING: To reduce the risk of fire, use 50 watt or less, 120 volt, reflector track type light bulb (not supplied). A standard household light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade.

GRINDING WHEELS

WARNING: THE USE OF ACCESSORIES AND ATTACHMENTS NOT RECOMMENDED BY DELTA MAY RESULT IN RISK OF INJURIES. Grinding wheels used with this grinder should be rated for 3600 RPM or higher and be 6" in diameter with a 1/2" arbor hole.

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 recommended 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.

DRESSING A

GRINDING WHEEL

When dressing a grinding wheel use a suitable silicon carbide stick type dresser, as shown in Fig. 15. 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.

CAUTION: DISCONNECT MACHINE FROM POWER SOURCE BEFORE CHANGING GRINDING WHEELS.

1.When changing wheels, remove the screws attaching the side covers to the grinder and remove the side covers.

2.To prevent shaft rotation, place a wedge between the grinding wheel and the tool rest. NOTE: Facing the front of the grinder: to replace the wheel on the left side of the grinder, turn the arbor nut clockwise to loosen; counterclockwise to tighten the arbor nut.

3.To replace the grinding wheel on the right, turn the arbor nut, counterclockwise to loosen; clockwise to tighten the arbor nut.

4.The arbor bushing should be saved, for future use, if the replacement wheel does not use the bushing.

WARNING: DO NOT OVERTIGHTEN WHEEL NUTS WHEN INSTALLING GRINDING WHEELS. TIGHTEN WHEEL NUT ENOUGH TO DRIVE THE WHEEL AND PREVENT SLIPPAGE.
