OPERATION
WARNING:
Your sander/polisher should never be connected to power
supply when you are assembling parts, making
adjustments, assembling or replacing sanding discs or
bonnets, cleaning, or when not in use. Disconnecting
sander/polisher will prevent accidental starting that could
cause serious personal injury.
LOCK-ON BUTTON
See Figure 2.
Your sander/polisher is equipped with a "lock-on" feature,
which is convenient when continuous operation for extended
periods of time is required. This feature can be used for both
high and low speeds.
To lock on, depress the switch trigger, push in and hold the
"lock-on" button located on the side of the handle, then
release the switch trigger. Release "lock-on" button and your
sander/polisher will continue running. To release the lock-
on feature, depress switch trigger and release it.
AUXILIARY HANDLE
See Figure 2.
An auxiliary handle is packed with your sander/polisher for
ease of operation and to help prevent loss of control. Any
loss of control could result in an accident, causing
possible serious personal injury.
The motor housings are designed so that the auxiliary handle
can be installed on either side of the unit.
TO INSTALL:
1. Fit bolt through hole in motor housing and thread into hex
nut provided internally.
2. Tighten bolt and handle securely.
INSTALLING OR REMOVING RUBBER DISC

lock hole with the two half-circle notches in motor hous-
ing. Lock spindle by inserting the pin provided through
