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.
