This tyre changer has been specically designed to demount and mount truck, bus and commercial van tyres, with rims from 14" to 56" and a maximum 2.400 mm diameter. Any other use is improper and therefore not authorized. Before beginning any kind of work on or with this machine, carefully read and understand the contents of these operating instructions.
The manufacturer shall not liable for any injury to persons or damage to things caused by improper use of this machine.
KEEP THIS MANUAL NEAR THE MACHINE AND CONSULT IT AS NEEDED DURING OPERATIONS.

The tire changer has a number of safety devices designed to guarantee the utmost operator safety:
1. Check valve on the spindle opening hydraulic line (inside the swivel connector, see g. B/1). This prevents the wheel from falling from
the spindle if the hydraulic line is accidentally broken.
2. Pressure relief valve factory set at 1.885 PSI (130 bar ±10%) (See Fig. B/2). This limits the pressure in the hydraulic circuit and ensure correct operation of the plant.
3. Pump motor overload shut-out (inside the electric enclosure). This provides automatic shut-off for the motor to prevent damage from overheating.

The machine is delivered in a wooden crate with pallet
The machine must be handled with a fork-lift truck with the forks positioned as shown in the gure A/2.

Once the packing material has been removed, check the machine visually for any signs of damage. Keep the packing materials out of the reach of children as they can be a source of danger.
N.B.: Keep the packing for possible future transport.

7.1
Choose the place the machine is to be installed in compliance with current work place safety regulations. The oor should not be broken
or uneven so that the machine will be stable and the platform rollers can move freely.
If the installation is outdoor, it must be protected by some kind of roong against rain.
The following work environment conditions are applicable: Relative humidity: from 30-95% without condensation; Temperature: from 32°-131° F (0-55° C.)
ATTENTION! The machine must not be operated in explosive atmospheres.
7.2
Maximum machine space requirements are 88.2x6.3 inches (2240x 1640 mm) with a minimum distance from walls as shown in the dia­gram.
CAUTION! These measurements are also the tyre changers working range. Persons other than specially trained and authorized operators are expressly forbidden to enter this area.

INSTALLATION
INSTALLATION PLACE
Position the tire changer lifting it with the specic bracket (1, Fig. A) with the tool carrier arm (2, Fig. A) lowered all the way, the spindle
(3, Fig. A) closed and the tool carrier slide (4, Fig. A) at its stop close to the arm.
The mobile control unit has no xed position, but it must be
positioned in a way that the user can observe the machine when working

The universal tire-changer must be installed on a levelled concrete oor at least 8” (20 cm.) thick, with a minimum concrete quality of B25 in accordance with DIN 1045 requirements (foundations). For your reference see the side drawing as well as the table herebelow.

If a oor of this type is not available on site, fastening points of the specied concrete quality are acceptable. The surface, on which the universal tyre-changer is to be installed, must be at and well levelled in all directions. Inclinations up to 0,25% relative to the horizontal can be compensated using suitable shims, wedges or the alike.
A
When working with tire assembly, whose weight is higher than 2,204 lbs (1000 kg.), it is necessary to
fasten the tire-changer to the oor by means of proper anchor bolts.
By means of a Widia bit Ø 16, drill a 0,63 inch (130 mm) into the oor passing through the holes provided on 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 sure the anchor bolts extend at least 4.9” (125 mm.) into the concrete slab, as indicated in the drawing. Tighten the anchor bolts fully.

Before making any electric hook up, check to be certain that the mains voltage corresponds to that stamped on the voltage tag (at­tached to the cord near the tire changer’s plug). It is absolutely essential that :
- the system is equipped with a good grounding circuit.
- The current instake is adeguately protected against overcurrents with fuses or automatic magneto-thermic switch.
Note the required power draw as highlighted on the data plate xed to the tire changer. Check to make sure the shop electric wiring circuit is dimensioned sufciently to carry this.
Work on the electric system, even if minor, must be done exclusively by professionally qualied electrician.
Manufacturer shall not be liable for any injury to persons or damage to things caused by failure to comply with these regulations and can cancel warranty coverage.
Connect the machine to the mains, switch “ON” (5, g. B/7) and check that the gearbox motor rotation corresponds to the indicating arrow (6, g. B/6). If not, switch two wires in the plug .
