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 3-g). 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 1-a). 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 revolving rear air outlet (picture 1-c).
The sander has been designed to be connected to suction systems with revolving fitting (picture 3-f).
When the sander stops, place it in a firm and safe position: the disc will not stop immediately.
Pad installation/replacement
Install the pad on the sander (picture 2-d) as follows:
- Use the open end wrench: fit it under the rubber guard and lock the rotation spindle. Loosen the pad by hand.
- Fit in a new threaded pad onto the rotation spindle. After placing the felt gasket, lock the pad by hand, holding the rotation
spindle with the open end wrench.
- Make sure that the pad has been fixed correctly.
- Place the sanding discs on the pad concentrically.
- The sander can rotate in one direction only, namely clockwise.
Sander speed regulation
Use the lever under the start button (picture 1-b) to adjust speed.
Always disconnect the air supply before making adjustments or fitting in the pad. This precaution will prevent the
pneumatic tool from being accidentally started.
Lubrication/Greasing
The pneumatic tool must be connected to a filter-lubricator unit provided with an air-oil microfog mixer (we recommend Beta item
1919F1/2), set at two drops per minute. This will result in a high-performing tool and wear-resistant mechanical parts.
If lubrication is not provided to the line, oil ISO 32 must be periodically poured into the pneumatic tool, through either the air
supply hole or the screw (pictures 4-f, 5-f).
