Fig.1
2-1 Transport
When transporting the machine it must be handle with a forklift truck with the forks
Positioned as show as in the Fig.1.

2-2 Unpacking
When unpacking, check to make sure all parts shown on the spare parts List/Assembly. Diagrams are included. If any parts
are missing or broken, please call the manufacturer or the dealer as soon as possible.

(3) Workplace Requirements

The machine’s workplace requires 1400(width)×1685(depth) with at least 500 mm of clear space from each wall. Place the tire
changer on a firm, smooth and unbroken floor. Drill four holes in the floor corresponding to the holes pre-drilled in the base of
the machine. Holes should be 80mm deep. Its diameter is 10mm. Then insert the expansion plugs and lighten with the 10mm
spanner.

(5) Optional Upgrade Accessories

Step 1. With assistance, place the vertical column in its tilt back seat on the Body Assembly. Push the air hose
through the large round hole into the body.

Step 2. Insert the pin (140) through the column and fasten it with
screws (143) and washers (142).

Step 3. Using the screw (137) tighten with the self-locking nut (139) and washer (138) to connect the pin
of the post tilting cylinder.

Step 4. Remove the four screws from the left side cover and remove it. Connect the air hose from the col­umn to the 6mm connector.

Step 5. Replace the side cover and fasten with its screws.

Step 6. Install the plastic guard (134) and fix it with the screws and washer (135,136).

Step 7. Install the stopper bolt (23) with self lock nut
(24). Don’t too tight.

5-2 Pneumatic link up

1) Push the clamping pedal all the way down to ensure that the jaws on the turntable do not open unexpectedly.

2) Connect the inflation gun, if it is to be installed, to its connector.

3) Connect the tire changer to a compressed air network (suggested working pressure from 8bar) using the connector. Use a compressed air
hose with on inside diameter of 7~8 mm.

5-3 Electric link up

1) Before making any electric link up, check to be certain that the main voltage corresponds to what is stamped on the voltage tag.

2) It is absolutely essential that the system is equipped with a good grounding circuit.

3) The machine must be connected to a power supply line circuit bracket set for 30mA

(6) Assembly procedure

(7) Bead Loosening and Demounting

This machine may operate differently from machines you
have previously operated. Practice with a regular steel
wheel and tire combination to familiarize yourself with
the machine’s operation and function.
A. Remember to remove all weights from both sides of

the wheel. Weights left on backside of wheel may cause the
wheel to be clamped unleveled. This may result in the com­bination mount/demount head contacting the rim causing
scratches. On alloy wheels, always rotate the wheel one turn
after setting the Mounting head to insure proper wheel
chucking.
B. Always review with the owner any nicks and
scratches on expensive wheel and tire combinations prior to
servicing.
C. Review the custom and special wheel section of this
manual prior to servicing custom or special tire/wheel com­binations.

Loosening the beads on a partially or fully inflated tire is
unsafe and causes excess movement and friction against
the bumper pads and excessive wear on pivots. Deflate
the tire completely to prolong the life of your machine.

1. Deflate the tire completely by removing the valve core
from the valve stem (figure 1). Be cautious and do not smoke
as a flammable gas could have been introduced into the tire
at some time.

Tires are always installed and removed from the rim’s

narrow side.
D. Always loosen the bead on the narrow side of the

wheel’s drop center first (tire removed in figure 2 for clarity).

Figure 2 - Determine Narrow Side of Wheel

Figure 1 - Remove Valve Core to Deflate Tire

E. The clamps on the table top may extend beyond the
table top itself. To avoid damaging the clamps, move them
to their full inward position before positioning a tire for bead
loosening.

F. Use extra care in positioning the bead loosener shoe
on larger wheels/tires, and on alloy wheels. Make sure the
shoe rests next to but not on the rim, and not on the tire
sidewall.

2. Pull the bead loosener shoe away from the machine and
roll wheel into position. The valve stem should be in the 2

o’clock position to accommodate a possible asymmetric

safety hump type rim. Position the bead loosener shoe
against the tire next to, but not on, the rim. Press the bead
loosener foot pedal to actuate the shoe and loosen the bead.
It may be necessary
to loosen the bead in multiple locations around the tire
(figure 3).

3. Turn the wheel around and repeat loosening procedure
on the other side of the wheel (figure 4). This should be the
long side of the drop center (figure 2).
