USE
Air supply connection
For correct use of the pneumatic tool, always keep to a maximum pressure of 6.2 bar, as measured at the tool inlet. Feed the
pneumatic tool with clean, condensate-free air (picture 1). Excessively high pressure or humidity in supply air results in shorter
life for the mechanical parts and may damage the tool.
Start / Stop
To start the sander, press the trigger (picture 1a). Keep it pressed during the job to be performed. Releasing the lever will cause
the pneumatic tool to stop after approximately 10 sec.
The sander is fitted with a rear air outlet.
The sander has been designed to be connected to suction systems; use the most appropriate available fitting (picture 2g).
When the sander stops, place it in a firm and safe position: the pad will not stop immediately.
Pad installation/replacement
The sander is supplied with two pads – triangular and rectangular (picture 4).
Install/replace the pad on the sander (picture 2) as follows:
- Fully unscrew all the eight screws under the pad; remove the pad and the centring ring.
- Fit the centring ring into the new pad; place the pad on the sander and fit all the screws, locking them manually.
- Make sure that the pad has been fixed correctly.
- Place the Velcro-backed abrasive sheets on the pad, and start sanding.
Sander speed regulation
- Use the adjusting wheel under the trigger (picture 1) to adjust minimum or maximum speed.
Suction system disconnection
The suction system can be disconnected by removing the valve and reinstalling it, after turning it 180 degrees, so that the words
"Central Vacuum Note" can be seen (picture 5). To remove the valve, use the nylon pin (picture 6) supplied with the sander, by
pushing it from the back (picture 6). When reinstalling it, make sure that the ball is always facing upwards.
Always disconnect the air supply before making adjustments or fitting in the pad. This precaution will prevent the
pneumatic tool from being accidentally started.
