Operator Protective Equipment

Personal protective equipment helps make tire servicing 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 provide 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 compression 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 tr ained personnel should service tires on the 9500. Read all safety and operating instructions thoroughly before using the tire changer.

ALWAYS

5.6 Demounting Tires From Multi-Piece Rim/Wheel Assemblies (T ube T ype Tires)

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 #8740 07611 (optional accessor y).

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/Wheel Assemblies

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).

Fig.44

WARNING

Page 20

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, mo ving the tool holder carriage towards the outside: This will make it much easier to remove the tube (fig.48).

10. Place the hook tool as in fig.49. The edge of the hook should be about 1” (2-3 cm) away radically from the rim edge and about 1” (2-3 cm) to the outside.

Fig.49

11. Put the long tire bar in between the bead and the rim.

12. Rotate the chuck counterclockwise until the tire is completely demounted.

During the final phase of the demounting operation remove the tire bar and hold the tire with both hands, in order to keep it in a vertical position.

5.9 Mounting Tractor And O.T.R. Wheels On One-piece Rims

1. Liberally lubricate both beads and the rim.

2. Firmly fit the mounting clamp to the outer rim

flange at 9 o’clock.

Roll the tire onto the foot board and hang it on the

mounting clamp attached to the rim edge.

3. Place the hook tool as shown in fig.50.

The edge of the hook should be about (1” or 2-3 cm) away radically from the rim edge and (1” or 2-3 cm) to the outside.

Fig.50

4. Turn the chuck clockwise until the first bead is

mounted. Remove the clamp.

5. Place the tube (if any) in the tire and secure the

valve stem to the rim.

6. Firmly fit the mounting clamp to the outer rim edge at 11 o’clock with valve stem at 10 o’clock in such a way as to hold the outer bead. If necessary make use of the tool to create the space to fit the clamp.

7. Place the hook tool as described in 5.5.2. Rotate the chuck clockwise till the tire bead is completely mounted. If necessary, use the bead bar to keep the bead in the drop center (fig.51).
