SELECTING THE RPM
The number of revolutions can be adjusted by using the speed
control (3) from MAX to OFF. The choice of speed depends on the
characteristics of the abrasive paper disc and the material to be
worked.
REPLACING THE ABRASIVE PAPER DISCS
- Used discs can be removed by simply tearing them off;
- new velcro discs are mounted by simply pressing them into the
backing pad, making sure that the holes cut in the disc coincide
with those in the backing pad.
USABLE DISCS
Ø mm 150 velcro backed abrasive paper discs with dust
extraction holes.
MAINTENANCE
All maintenance operations are carried out with the tool
disconnected from the compressed air supply.
At the end of each work session, or when required, remove any
dust from the body of the tool using a jet of compressed air.
Lubricate the machine regularly (every 50 hours of operation)
by inserting 2/3 drops of specific oil (synthetic oil without
silicone, ISO 32) into the compressed air connection, keeping
the device in a vertical position, with the connection facing
upwards. After this operation, connect the machine to the
power supply and set it in motion for a few seconds.Lubricate
the machine as described above before storing it for long
periods of inactivity.All damages deriving from incorrect or
inadequate lubrication are excluded from the warranty.
No other maintenance operations must be undertaken by the user.
Maintenance and cleaning of the inner parts, must be carried out
only by an authorized customer-service workshop.
NOISE / MEAN ACCELERATION VALUE
The noise level produced and themean quadratic acceleration
value are measured according to regulation
UNI EN ISO 15744 - EN ISO 28927
.
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.
Danger!
The indicate measurements refer to new power tools. Daily usa
causes the noise and vibration values to change.
