Operating Instructions – Sanding
To operate the machine as a sander follow this procedure:
1. Move machine to work location. Decide the best approach
to sanding the desired area. When sanding the area, work
so that you are moving away from the power supply. This
will help to avoid entanglement with the power cord and
reduce the need to move the power cord as frequently.
2. Install the abrasive. Use the same procedure outlined
in MACHINE SETUP for installing the pad, to install the
abrasive. Peel the fi lm off the back of the abrasive; center
the abrasive over the pad and press it against the pad.
The adhesive on the abrasive will hold it to the pad.
NOTE: When using screen abrasive, set the screen on
the fl oor then move the machine over the screen.
Lower the machine until the pad comes to rest on
the screen. Make sure the screen is centered on
the pad.
WARNING: Injury can occur if the machine is connect-
ed to a power source while installing the
pad or abrasive. Disconnect the machine
before installing the pad/abrasive.
3. Connect the machine to an appropriately fused and
grounded circuit.
4. Release the handle by pressing up on the locking lever.
Bring the handle to a comfortable position.
CAUTION: Do not lock the handle. Locking the
handle will prevent the machine from
resting evenly on the pad and diminish the
machine performance and reliability.
5. Push the interlock button (1), and apply pressure to the
levers (2). To stop the machine, release the levers (2).
See fi gure 6.
CAUTION: To prevent damage to the fl ooring and to
reduce swirling, keep the machine in mo-
tion while the motor is running.
NOTE: For sanding cuts and sandpaper, see page 9.

sive.

grounded circuit.
2. Release the handle by pressing up on the locking lever.
Bring the handle to a comfortable position.
CAUTION: Do not lock the handle. Locking the
handle will prevent the machine from
