excessive wear, cracks or ageing on the
connecting hose.

Supply pressure adjustment

The machine is equipped with a pressure governor only in
case the pressure governor optional has been purchased.
WARNING!
If the adjustment procedure below is not properly
respected in each step or if the knob is forced ex-
cessively in the direction of the maximum pressure
(clockwise), there is a risk of damage to the device
and the operator's safety can be compromised.
1.
Adjust the pressure as required, according to the
compressor performances.
2. In order to ensure proper performance of the vacuum
cleaner, check that the supply piping diameter is
adequate, that is to say not less than a nominal diameter
of 14 mm.
3. Connect the vacuum cleaner to the air supply, then open
the on/off valve (16, Fig. 1).
