OPERATION
STARTING AND STOPPING SANDER
Failure to read and understand the instructions, warnings and safety guidelines provided in this manual
may lead to serious injury and / or damage to machine or the work piece.
Be sure the sanding disc is securely installed onto the disc plate.
Make sure the table tilt locking levers are secured and that the table is locked in place at the desired
angle or tilt.
Make sure the machine is installed on a flat, sturdy and stable surface able to support the weight of the
machine and the work piece to be sanded.
NOTE: The DELTA
®
12” Disc Sander uses a Safety Key
(A), shown in Figure 5. The Safety Key must be in place in
order to operate the machine. Before attempting to turn
on the sander, ensure the Safety Key is installed.
The ON/OFF switch (B) is located on the top of the
motor. To turn the sander “ON”, move the switch
toward rear of sander.
To turn the sander “OFF”, move switch to the front
position as shown.
NOTE: The sanding disc on this sander rotates
counterclockwise. In order to prevent injury and
produce good results, always sand on the left side
of the table only. Never work on the right side of the
table where the disc is rotating up as it is difficult to
control the work piece.

REMOVING THE SAFETY KEY TO LOCK SANDER
When the tool is not in use, the switch should be locked
in the “OFF” position. This can be done by grasping
the Safety Key (A), shown in Figure 5, and pulling it out
of the switch. With the Safety Key removed the switch
will not operate. Should the Safety Key be removed
while the machine is running, the switch can be turned
“OFF” once, but cannot be restarted without inserting
the Safety Key.
USING THE MANUAL DISC BRAKE
Apply the brake when the switch is in
the “off” position only. Applying the
brake while switch is in the “on” position may
damage the machine.
This 12" Disc Sander is equipped with a manual disc
brake that brings the sanding disc to a safe stop once
the power switch has been turned to the “OFF” position.
The manual disc brake should only be used once the
sander has been turned off. To apply the manual disc
brake, press down on brake lever (A) as shown in Figure
6.
