Operator Protective Equipment
Personal protective equipment helps make tire servic-
ing safer. However, equipment alone does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury in
typical shop activities. Eye protection is essential during
tire service activity. Safety glasses with side shields,
goggles, or face shields are acceptable. Back belts pro-
vide support during lifting activities and are also helpful
in providing operator protection. Consideration should
also be given to the use of hearing protection if tire
service activity is performed in an enclosed area, or if
noise levels are high.
Safety Devices
This machine has several protectors to prevent com-
pression or crushing hazards to body areas. Keep these
devices properly maintained and do not disable or in
any way shortcut the safety controls and opertations.
There is a micro-switch protection under the chuck
arm to prevent compression.
The rotation speed of the chuck has been limited to a
maximum of 8 rpm to prevent dragging or en-trapping
hazards.
There is an emergency button on the portable control
unit.
Important Safety Instructions
Only properly trained personnel should serv-
ice tires on the 9500. Read all safety and
operating instructions thoroughly before
using the tire changer.
ALWAYS remove all wheel weights and the valve core
to deflate the tire before servicing.
ALWAYS cover the electric motor and switch box
before hosing down the tire changer. Be sure water
does not enter the motor or switch box.
ALWAYS disconnect the electric power and air supply
before attempting any maintenance.
ALWAYS keep all working surfaces clean and free of
tire lube buildup.
ALWAYS be aware of what each person is and will do
before attempting any two-person operation.
Safety Precautions
A. Before servicing any tires, wheels or rims all per-
sonnel should receive thorough training for the proper
servicing of truck tires, wheels and rims. Consult with
your local city, country state, and national safety and
health administrators to receive clarification of any pub-
lications available governing this serious matter.
B. During the use and maintenance of the machine it
is mandatory to comply with all laws and regulations for
accident prevention.
C. The electric power source must have a ground
cable and the ground cable of the machine (yellow and
green) must be connected to the ground cable of the

This tire changer is not designed as a safety device or
stand for bead seating or inflation.
ALWAYS use an approved inflation chamber or infla-
tion cage.
The following safety instructions are for one piece
wheels only. Refer to the manufacturer’s or R.M.A. pro-
cedures for multipiece wheels.
ALWAYS use an approved inflation chamber or infla-
tion cage equipped with a grip chuck and a remote infla-
tion gauge and valve. DO NOT OVER INFLATE! Tire or
wheel failure during and after inflation may result in an
explosion capable of causing severe injury or death.
ALWAYS inflate the tire to manufacturer’s recom-
mended cold operating pressure.
NEVER reinflate a tire that has been run underinflated
or flat without first demounting the tire and checking for
wheel and tire damage.
ALWAYS inspect the tire interior for loose or broken
cords, cuts, penetrating objects, and other damage to
the carcass. Discard tires that cannot be properly
repaired.
NEVER rework, weld, heat or braze wheels.
NEVER strike the tire or wheel with a hammer.
ALWAYS be sure the tire diameter exactly matches
the wheel diameter.
Tire failure under pressure can be hazardous.
Place the wheel inside an approved inflation
chamber or cage before inflating. Use an
approved remote inflation valve, hose, and
gauge. ALWAYS wear safety goggles for eye
protection. Do not stand beside the wheel or
cage during inflation. Keep hands and other
parts of the body out of the cage during
inflation. Observe the tire pressure fre-
quently. Do not exceed the manufacturer’s
recommended maximum inflation pressure.
Failure to follow these instructions may
cause the tire and rim to separate with
tremendous force, resulting in serious per-
sonal injury or death.

Before mounting a tire on a rim, pay atten-
tion to the following:
A.The rim and all its parts must be clean and in good
condition: If necessary clean and paint it after remov-
ing all wheel-weights, including tape weights inside
the rim.
B. The tire must be clean and dry, without any dam-
age to the bead and the carcass.
C. Replace the rubber valve stem with a new one or
replace the “o” ring if the valve stem is made of metal.
D. If the tire requires a tube or a flap, make sure the
tube is dry and in good condition.
E. Lubrication is necessary to mount the tire cor-
rectly and get a proper centering. Be sure you are
using approved lubricant only.
F. Make sure the tire is the correct size for the rim.
5.1 Locking Rims
Lift the tool holder arm and move the tool holder car-
riage all the way out.
Put the wheel in vertically and roll it on the foot board.
Be sure to use alloy adapters when applicable.

If the wheel is very heavy be sure to use a
suitable external lifting device (i.e. fork lift,
crane etc.).
Close the jaws of the chuck and move the chuck
approximately to the center of the rim. Move the foot
board toward the chuck and move the chuck up-down
while opening the chuck arms until the rim is clamped
properly (fig.17).
Fig.17
CAUTION
Attention! The drop center of the rim (when it
exists) must be kept towards the outside of the
machine (fig.16).

5.2 DemountingTubelessTruckTires (Up to
13”Wide)
The tubeless truck tires are mounted on drop-center
rims with a conical base. It is possible to demount
these tires simply by pressure, with a proper lubrica-
tion (fig.18).
Fig.18
1. Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire.
2. Position the bead loosener disc or tubeless roller
(option) as shown in fig.19, fig.20.

5.4 Demounting Duplex and Supersingle
TubelessTruckTires (Over 13”Wide)
Note: For this operation the mount/demount tool is
required.
1. Loosen the bead of the tire as described in #5.2.1-
5.2.6.
2. For this type of tire it is not possible to demount
both beads at the same time with the roller as
described in #5.2.7.
Engage the hook of the mount/demount tool
between the bead and the rim.
3. Lift the chuck arm enough to clear the hook 1” - 1
1/2” from the rim flange. Move the mount/demount
tool towards the outside. This will allow you to place
the long bar in between the bead and the rim flange for
necessary prying (fig.30).
Fig.30
4. Rotate the chuck counterclockwise until the outer
bead is completely demounted (fig.31).
Fig.31
5. Demount the inner bead with the bead breaker
disc, as described in #5.2.7. (fig.32).

5.5 Mounting Duplex And Supersingle
TubelessTruckTires (Over 13”Wide)
1. Hang the inner bead of the tire on the mounting
clamp (fig.33).
Fig.33
2. Position the mounting hook about 3/4” (1.5 cm) to
the inside of the rim edge and 1/2” (1 cm) away radi-
cally.

5. Rotate the chuck clockwise until the tire is com-
pletely mounted.
Ensure that outer bead descends into the drop center
when the clamp is opposite to the mount/demount
tool (fig.36).

Never use hand pressure to hold the tire
onto the rim.
Stop the chuck before one complete turn is
made to avoid serious damage to the
mounting clamp and to the rim.

5.6 Demounting Tires From Multi-Piece
Rim/WheelAssemblies (TubeTypeTires)
The multi-piece rim/wheel assembly can be in two or
more pieces (fig.37).
Fig.37
1. Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire completely.
2. Position the tool close to the rim edge (fig.38).
When the lock ring is stuck to the tire bead, (on the
O.T.R. tires) to loosen the bead, it is necessary to hold
the ring to the rim with the appropriate clamp
#874007611 (optional accessory).
Fig.38
3. Turn the chuck counterclockwise and loosen the
bead as described in #5.2.1.-5.2.3. Do not lubricate.
4. To remove the lock ring, squeeze one edge with
the proper bar and place the bead loosener disc as
shown in fig.39.
Fig.39
5. Turn the chuck clockwise (or counterclockwise)
until the lock ring is completely removed.
No one should stand in front of the wheel
when removing the lock ring.
Continue to demount all components of the rim man-
ually or with the disc tool.
6. When loosening the inner bead be sure not to
damage the valve stem (fig.40).

5.7 Mounting Tires Onto Multi-piece
Rim/WheelAssemblies
1. Roll the tire on the foot board (the tube and flap
must be in place).
Note: O.T.R. tires and rims are very heavy and an out-
side lifting tool may be required.
For tube type only, the valve should be placed at 12
o’clock, for easier mounting.
2. Slide the tire onto the rim with the foot board or
with the bead loosener disc, if necessary.
3. Mount all the assembly components.
4. Engage one edge of the lock ring in its seat and
complete the mounting process with the bead
loosener disc.
In the initial mounting phase hold the rim edge in its
seat with a bar (fig.41).
Fig.41
Do not inflate the tire on the machine.This
machine is not an inflation device.
For inflation place the wheel in an approved
inflation restraint device. Refer to OSHA
standard number 1910.177.
5.8 Demounting Tractor and O.T.R. Wheels
With One-Piece Rims
These wheels may be tube-type or tubeless.The rim
has a slightly conical surface and a very high rim flange
(fig.42) which does not allow you to demount the tire
by simple pressure from the roller as described in
@5.2.
Fig.42
1. Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire completely.
2. Place the disc tool next to the rim edge and
loosen tire inner bead.
3. Loosen the outer bead in the same way, taking
care not to damage the valve stem (fig.43).
Fig.43
4. Lubricate both beads and the rim surface (fig.44).

WARNING

5. Place the hook tool between bead and rim
(fig.45).
Fig.45
6. Lift the chuck arm to move the hook tool away
from the rim edge (1” or 2-3 cm).
Move the tool towards the outside to apply the long
tire bar (fig.46).
Fig.46
7. Turn the chuck counterclockwise until the outer
bead is completely demounted (fig.47).
Fig.47
8. If the tire is tube-type, push the valve stem to-
wards the inside of the rim.
9. Lift the tool holder arm to the rest position.
Shift the tire from the rim, moving the tool holder car-
riage towards the outside:This will make it much eas-
ier to remove the tube (fig.48).
