Chose the installation site according to the current rules on Safety at Work.
The automatic tire-changer needs to be connected to the electric network. It is therefore advisable to install it in a place where this connection is
available.
Moreover, the installation space must allow the operator to use the machine and all its components without any restriction (see dimensions given in
g. 5) In case of installation outdoor it is necessary to protect the machine against rain by means of any kind of footing.
6. INSTALLATION
6.1_Installation site
IT IS FORBIDDEN to use the machine in explosive at-
mosphere
Fig.5
The tire-changer must be installed on a level concrete oor at least 6” (15 cm) thick, with a minimum concrete quality of B25 in compliance with DIN
1045 requirements (foundations). See the diagram herebelow.
If a oor of this type is not available on site, a suitable foundation under the bearing points must be provided. The installation surface must be levelled
in all directions.
Inclinations up to 0,25% relative to the horizontal can be compensated using suitable shims, wedges or the alike.
When working with wheels, whose weight is higher than 2,204 lbs (1,000 kg)., it is necessary to fasten the tire-changer
to the oor by means of proper anchor bolts.
Use a Ø 16 widia bit to drill the oor to a depth of at least 0.63 inch (130 mm)., passing through the holes already provided in the base frame.
If there is an additional oor covering (B), or if shims or wedges are necessary for levelling (C), longer anchor bolts must be used.
Place an anchor bolt into each hole.
Make always sure that the bolts extend at least 4.90” (125 mm) into the concrete slab, as shown in g. 6
Tighten the anchor bolts.

All the operations on electrics must be carried out by proffessional electrician. Before making electric hoop up, check to make
sure the main voltage corresponds to that pronted on the voltage tag (attacched to the cord near the plug)
It is absolutely essential that:
- the system is equipped with a good grounding circuit
- protected against overcurrents with fuses or automatic magneto-thermic switch
Note the required power drow as highlighted on the data plate xed to the tire charger. Make shure the shop electric wiring circuit is dimensioned
sufciently to carry this.
The voltage drop with full load must never exceed 4% of the voltage nominal value shown by the data plate.
Connect the tire-changer to the power supply network, switch it on and check the motor running direction (same as indicated by the arrow – g.9).
In case of opposite running direction, it is necessary to have two wires inverted in the plug.
The motor run made in the opposite direction, if longer than a few seconds, can cause irreparable damages to the motor itself.
Remarks: both electrical motor and hydraulic unit motor are equipped with an overload cutout (g.10) against overloads.

11) Move the rim about 1,5-2 inches (4-5 cm) from the tool, making sure the hook does not detach from the rim.
12) Move the hook-tool so that its red reference dot is about 1,2 inches (3 cm) inside the rim.
13) Insert lever between rim and bead at the right of the tool (Fig.33)
14) Press down the lever and lower the tire to bring the edge of the rim about 1/4” (5 mm). from the hook-tool.
Turn the tire counterclockwise, pressing down on lever until the tire comes completely off the rim.
1) If the rim has been removed from the spindle, lock it back as described in par. “RIM CLAMPING”
2) Lubricate both beads and rim with tire manufacturer recomanded lubricant.
3) Attach the g-clamp to the outside edge of the rim at the highest point
(Fig. 34).
CAUTION! Make sure the g-clamp is rmly attached to the rim.
4) Put the tire onto the ramp and lower the spindle (make sure the g-clamp is at the highest point) to hook the rst bead to the g-
clamp.

5) Lift the rim with the tire hooked to it and turn it counterclockwise about 6-8 inches (15-20 cm). The tire will be positionedinclined across
the rim.
6) Move the tool carrier arm to its non-working position. Move it to the inside face of the tire and rehook it in this position.
7) Make sure that the hook-tool is positioned facing the tire bead. If not, turn it of 180° (by releasing the locking pin, 15, g. 32).
8) Move the tool forward until the red reference dot is lined up with the outside face of the rim at about 1/4” (5 mm) from it (Fig. 35).
9) Move to the outside of the tire and check the exact position of the hook tool visually and adjust it as needed, if necessary. Then turn
the spindle clockwise until the clamp is at the bottom (6 o’clock). First bead will be mounted on the rim.
Remove the g-clamp.
10) Remove the tool from the tyre.
11) Move the tool carrier arm to its non-working position. Move it to the outside of the tire.
12) Turn the tool 180° (by releasing the loking pin, 15, g. 32.)
DANGER!
When the beads come off the rim, the tire will fall. Check to make sure there are no bystanders in the
work area.

13) Turn the spindle until the valve is at the bottom (6 o’clock).
14) Move the ramp (10 g. 36) under the wheel and lower the spindle until the tire is pressed down against the ramp. Move the ramp
slightly towards the outside so. The tire will open a little, to create some space to insert the inner tube.
NOTE: The valve hole may be asymmetrical to the centre of the rim. In this case position and insert the inner tube as shown in Fig. 36.
Insert the valve through the hole and x it with its locking ring.
15) Fit the inner tube into the drop center of the rim (NOTE: to facilitate this turn the spindle clockwise).

16) Turn the spindle until the valve is at the bottom (6 o’clock).
17) Inate the inner tube a little (until it has no folds) so as not to pinch it while mounting the second bead.
18) Attach an extension to the valve and then remove the locking ring.
The purpose of this operation is to allow the valve to be loose so that it is not ripped out during second bead mounting.
19) Lift the tire again and attach the g-clamp outside the second bead about 8 inches (20 cm) to the right of the valve (Fig. 38).
20) Turn the spindle clockwise until the clamp is set at 9 o’clock position.
21) Move the tool carrier arm to its working position.
22) Bring the tool forward until the red reference dot is lined up with the outside face of the rim at about 1/4” (5 mm) from it.
23) Turn the spindle clockwise until the tire is completely mounted on the rim. (Fig. 39)
24) Remove the g-clamp. Remove the tool by turning the spindle counterclockwise and pulling the tool arm to the outside.
25) Tip the tool carrier arm to its non-working position.
26) Position the ramp directly under the tire and lower the spindle until the tire rests on the platform.
27) When the tire is resting on the ramp, check to make sure the valve is perfectly centered with its hole. If not, turn the spindle slightly to
adjust the position. Fix the valve with its locking ring and remove the extension.
28) Remove the rim clamping hub nut. Support the tire to prevent it from falling off.
29) Move the ramp to release the tire from the spindle and remove the tire.
DANGER! PONTETIALLY HAZARDOUS OPERATION!
Do it manually only if you are certain you can keep the tire balanced. For large and heavy tIres an adequate
lifting device must be used.
