* These performances have been obtained after having tested the wheel gun on a testing-bench, that is on fixed bolts,
which have been tightened for 3 seconds. Please remind that, during the tightening/loosening on a Formula 1 car’s
wheel hub you lose most of the torque, due to the hub’s spin. Furthermore the performances change depending on the
wheel gun’s operating-time on each nut, reminding that the correct operating-time on one single nut is, on average,
less than one second.
** DP 4000 30BAR Unhanded (UH) version: Maximum free speed is 15.000 RPM (at 30 bar) - Ultimate torque is 3.500 Nm.
*** DP 4000 30BAR with carbon cover: Weight is 3,90 kg.
L
It is recommended to use a whip hose
(flexible hose for compressed air with a
minimum length of 46 cm (18 inch)) with a
threaded male to connected to the air inlet of
the wheel gun, and a male quick disconnect
coupling at the other end.
L
Fit a the whip hose to the air pressure regulator
using a specific supply hose.
L
Use a supply pipe of minimum inner
diameter 13 mm (1/2 inch) suitable for its
intended use.
L
Use couplings with minimal nominal bore 10
mm (25/64 inch) suitable for their intended use.
L
It is recommended to use a high pressure oiler
to constantly lubricate the motor and keep
steady the wheel gun speed.
View figure Fig.3.
L
It is allowed to use exclusively on industrial
plants with compressed air.
L
Make use of a supply system that observes
the indicated pressure values (max 10%
over the maximum value indicated) using an
air pressure regulator supplied by a system
observing the current safety standard, and
that it is subjected to regular checks.
L
The components of the supply system must
be designed and constructed in accordance
with the safety requirements contained in
current international standards.
L
Before any work on the supply system, always
check that the line is depressurized (no air
pressure).
