TECHNICAL DATA
SYSTEM COMPONENTS
View figure Fig. 1.
L
Make use of a supply system that observes
the indicated pressure values (max 10%
over the maximum value indicated) using
a pressure reducer supplied by a system
observing the current safety standard.
L
Fit a standard male fast connection for
compressed air to the threaded hole.
L
Use a supply pipe of minimum inner
diameter 16 mm.
L
Supply only with dehumidified compressed
air with no pollutants.
L
If possible fit a supply filter, to be cleaned
regularly.
GENERAL INSTRUCTIONS
L
If you have used a lower torque, screw
on again using an appliance with the
right torque, in order to avoid the risks of
insecure tightening.
L
If you avoid operating at a higher pressure
than the one required you will save energy,
make less noise, and have less wear on the
appliance.
L
Always use an impact wrench with the
tightening torque corresponding to the one
required by the application.
L
If by mistake you have used a higher torque
than the one required:
⚪
in the case of screwing, replace the bolt
and reform the tread you screwed it onto,
because of it yielding;
⚪
in the case of unscrewing, replace the
bolt anyhow and check the tread you
screwed it onto.
