3. GENERAL

3.1_General SAFETY rules

The tire-changer has been designed and manufactured exclusively for mountig/demounting tires onto/from the rims.

Any other use is to be considered improper. The manufacturer cannot be held responsible for any damage or injury caused by an improper use.The

machine may only be used by adult staff, previously authorized and trained. Any tampering or modication, relieves the manufacturer of eventual damages referred to the mentioned actions.The tire-changer is equipped with

instruction and warning stickers designed and produced to last over time.

In case they get damaged or destroyed the user must require the manufacturer for replacing them, using #2019026 for reference. Any work on the electrics, however small, must be carried out by qualied staff according to the current national regulations. Only use Original spare parts listed in the Spare Parts Catalogue. The manufacturer cannot be held responsible for any claim caused by use of

non-original spare parts.

The tire-changer may be equipped with accessories, which must be listed and approved by the manufacturer. The manufacturer cannot be held

responsible for any injury or damage deriving from unapproved accessories.

It is forbidden to use the tire-changer in places having potentially explosive atmosphere.

WARNING

In case the warning labels are unreadable or have been removed, it is necessary to replace them immediately. Do not use the tire-changer if one or more labels are missing. Do not add any object which could prevent the operator’s from seeing the labels. When ordering the labels always use the ref. code given in this diagram as a reference

TRANSPORT, MOVING AND STORING

The machine is delivered in a cardboard box on wooden pallet.

The machine must be transported in its original package and kept in the position shown on the package itself.

Move the machine by means of a fork-lift truck having enough loading capacity. Fit the forks as shown in g.4 Should the machine be temporarily stored, make sure that the storing place has the following requirements:

- Max. relative humidity: 95%

- Temperature: min. 32°F (0°C); max. 131°F (55°C)

5. UNPACKING

Fig.4

After having removed the package, make sure that the tire-changer has not suffered any damage during transportation. Take out the standard delivered accessories too.

The package units must be stored in a safe place, out of children’s reach, being them a possible source of danger. Keep the packing for possible future transport

Unpack the machine by using the related hook for lifting it. Originally placed on the main chassy, close to the clamping chuck arm (21, g. 2). During this phase pay attention not to damage the control unit, which is not xed.

After placing the machine in its installation position, always remove the liftinf hook, which may interfere with regular oparation.

6.1_Installation site

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.

IT IS FORBIDDEN to use the machine in explosive atmosphere

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.

GROUND

REINFORCED CONCRETE

ELECTRO-WELDED GRID

PEBBLE GRAVEL

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.

6.3_Electrical connection.

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.

6.4_Operation test

Before working with tire-changer it is necessary to carry out some tests to check the correct operation and installation as well.

All the following operations must be carried out with the tool-arm (17 g 2) set in non-working position.

Press handle 18 to unlock the arm. Pull it and tip it in its non working position. Refer to g. 11 for carrying out the running test.

Switch on the main switch (1) on control panel. The machine must turn on.

Set lever (2) in the position indicated by the continuous arrow to let the clamping (6) turn COUNTERCLOCKWISE.

Set lever (2) in the position indicated by the dashed arrow to let the ange (6) turn CLOCKWISE.

Set lever (3) in the position indicated by the continuous arrow to move the carriage (16) AWAY FRON THE SPINDLE.

Set lever (3) in the position indicated by the dashed arrow to move the carriage (16) FORWARDS THE SPINDLE.

Set lever (4) in the position indicated by the continuous arrow to LOWER the spindle.

Set lever (4) in the position indicated by the dashed arrow to LIFT the spindle.

When the spindle carrier arm is lowered, there is always a potential for crushing anything in its movementrange. Always work fron the position given in the intructions keeping well out of worning range of the various moving arm
