REGULATION OF
THE AIR PRESSURE
L Before the use, always perform a dynamic
adjustment of the supply air pressure
(view figure
Fig.5). Adjust the supply
air pressure on the low pressure gauge
turning the adjusting screw of the air
pressure regulator while keeping the
trigger pressed.
L Do not exceed the maximum supply air
pressure of 30 bar (with wheel gun running).
INSTALLATION OF ACCESSORIES
Before changing an accessory, always make
sure that the air supply line is depressurized (no
air pressure), and only after disconnecting the
wheel gun and replace it. Use only accessories
suitable for the job (view our catalogue for
accessories).
Use only impact sockets with a hole for the
locking pin.
Do not use chrome sockets or for manual use.
Do not use square drive adapters (reductions
or multiplies).
Always check that the locking pin of the socket
is present and secured firmly. To install the
wheel nut socket, proceed as follows:
L Mark each clutch cover with the wheel gun's
serial number.
L Remove the four clutch cover (hammer
case) screws, discard lock washers.
L Holding the 1" square drive, remove the
anvil shank, clutch cover bearing and clutch
cover from gun. Clutch spring should
remain with clutch shaft, clutch plate and
clutch housing. Retain the anvil shank,
clutch cover bearing and clutch cover as an
assembled unit.

OPERATING AND MAINTENANCE MANUAL
HANDLING
L Please pay attention to your wheel gun
selector plate type (3 port or 2 port version).
L Slide the rotation reverse shaft
Fig.1-I) and push the trigger
Fig.1-C). See the figure
the rotation direction of the square drive.
L Avoid accidental starting, being careful not
to unwittingly act on the trigger
Fig1-C).
L Using an appropriately sized aluminum
block, support the 1" square drive from
the bottom. This will provide the base
for pressing the socket onto the square
drive. Make sure the block is tall enough
to allow clearance for the clutch cover.
L In ideal situations, an aluminum block
should be machined to fit either the I.D.
or the surface of the socket. This will be
used for pressing the socket onto the
square drive. Special attention must be
taken to assure the inner O-ring groove
(retention ring) is not damaged by a tool
used on the socket I.D.. A tool used
on the magnet surface (i.e. for wheel
nut sockets with magnets) should also
fit properly to prevent damage to the
magnets. In certain situations a thick
block of aluminum can be used to press
directly on the teeth of the socket (i.e.
for wheel nut sockets with fingers) for
installation. This is not a recommended
practice and should only be used when
a proper press tool cannot readily be
made.
