GENERAL WARNINGS
The safety and accident prevention instructions are reported in the
“SAFETY INSTRUCTION” booklet which forms an integral part of
these documents. This OPERATING INSTRUCTION MANUAL
indicates the additional information required specifically for use of
the tool.
CORRECT USAGE
This tool is designed to be used as a sander.
Read all the warnings, instructions, indications provided on
drawings and specifications supplied with this tool.
Failure to comply
with all the instructions provided below may cause serious injuries.
This tool is not intended to be used for metal brushing, polishing
and cutting operations.
The use of this tool for unintended applications
may cause hazards and injuries to people.
NOISE / MEAN ACCELERATION VALUE
The noise level produced and the mean quadratic acceleration value
are measured according to regulation
UNI EN ISO 15744 -
EN ISO 28927.
(*) Vibration level defined by previous regulation EN ISO 8662.
Displayed emission values are comparative and are to be employed
for a provisional assessment of the operator’s risk exposure during
the work period. Appropriate evaluation of work period must also
include tool’s idle and stop periods. These emission values represent
the tool’s main applications. If the tool is used for other applications,
with other accessories, or if it does not undergo regular maintenance,
emission values can significantly increase during operations.

STARTING UP
Before starting-up the tool, ensure that:
- the packaging is complete and does not show signs of having been
damaged during storage or transport;
- the available compressed air production and distribution plant is
capable of satisfying the requirements reported on the tool’s
identification plate.
ASSEMBLING THE TOOL
Assemble the compressed air connection (not supplied) by screwing
it into its seat (5).
Ensure that, when compressed air is connected, the
pneumatic tool activation switch (2) is disconnected.
For the compressed air supply a compressor complying with the
technical characteristics listed in the tool data label must be used.
All instruments, connection hoses and pipes must be suitable for
the corresponding pressure and quantity of air necessary.
COMPRESSED AIR CONNECTION
(NOT SUPPLIED)
The tool is supplied without the compressed air connection; the user
can use either a quick release coupling or hose type connection
according to his needs, as long as they have an hole of air passing
mm. 8.
In the latter case the air line must be fixed to the nozzle by a hose
clip.
STARTING AND STOPPING
- Starting: push the control lever (2) forward towards the body of
the tool and keep it pressed;
- Stopping: release the control lever.
