FLEXIBLE LAMP

The flexible lamp operates independently of the grinder.

To turn the lamp on and off, rotate switch (A) Fig. 11.

WARNING: To reduce the risk of fire, use 40 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 8" 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. ALWAYS maintain

a distance of 1/8" or less between the grinding wheel

and the tool rest. Adjust the tool rests and spark guards

as the grinding wheels decrease in size with use.

DRESSING A

GRINDING WHEEL

When dressing a grinding wheel use a suitable silicon

carbide stick type dresser, as shown in Fig. 12. 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. ALWAYS maintain a

distance of 1/8" or less between the grinding wheel and

the tool rest. Adjust the tool rests and spark guards as

the grinding wheels decrease in size with use.
