FLEXIBLE LAMP
The flexible lamp operates independently of the grinder.
To turn the lamp on and off, rotate switch (A) Fig. 17.
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 lampshade.

OPERATION
STARTING AND STOPPING GRINDER
1. The on/off switch (A) Fig. 18 is located on the front of
the grinder. To turn the machine
“ON”,
move the switch
up to the “ON” position.
2. To turn the machine
“OFF”,
move the switch (A)
down to the “OFF” position.
MAKE SURE THAT THE SWITCH IS IN
THE “OFF” POSITION BEFORE
PLUGGING IN THE POWER CORD. IN THE EVENT OF A
POWER FAILURE, MOVE THE SWITCH TO THE “OFF”
POSITION. AN ACCIDENTAL START-UP CAN CAUSE
INJURY.
LOCKING SWITCH IN “OFF” POSITION
IMPORTANT:
When the machine is not in use, the
switch should be locked
in the “OFF” position to prevent
unauthorized use,
using a padlock with a 3/16" diameter
shackle inserted through the holes at (B) FIg. 18.

GRINDING WHEELS
THE USE OF ACCESSORIES AND ATTACHMENTS NOT RECOMMENDED BY DELTA MAY RESULT
IN RISK OF INJURIES.
Grinding wheels used with
Model 23-725
grinders should be rated for 1800 RPM or higher and be 8" in diameter with
a 5/8" or 1" arbor hole.
The arbor bushing should be saved, for future use, if the replacement wheel does not use the bushing.
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.
