3.2.2

Assembling "I" versions

Follow the instructions given under paragraph 3.2.1. and indications below:
l) fit the reservoir 1 (Fig.11) onto the base 2 from the back.
Tilt so not to damage the valve fittings 3 as shown in Fig. 12). Align the four holes onto the reservoir brackets
with the base screws 2 and then fit nuts, check nuts and washer. (Tighten to 8 Nm approx.);
m) connect the two hoses 1 (Fig. 13) –preassembled onto the rotary spindle blades- with the corrugated fittings and
then secure with the supplied clamps;
n) connect pipe A (coming from non-lubricated air unit) with blowing valve 3 feed connector 2;
o) connect pipe B (coming from pedal unit lower valve 4) with blowing valve 3 lower connector 5;
p) connect pipe C (coming from inflation unit 6 fitted onto post) with valve 8 connector 7.
NOTE: In case the machine is packed with the post already assembled, pipe C is already connected.
3.2.3

Assembling "IT" versions

Follow the instructions given under paragraph 3.2.1. and indications below:
l) take the left lateral guard 1 (Fig.14) off;
m) fix the tank 2 to the support flange 3 using the screws 4 and nuts 5 equipped on issue;
n) fix the flange 3 to the machine 6 using screws 7, nuts 8 and the waschers 9.
o) connect pipe A (Fig.15) (coming from non-lubricated air unit) with connector 1;
p) connect pipe B (coming from pedal unit lower valve 2) with blowing valve 4 connector 3;
q) connect pipe C (coming from inflation unit 5 fitted onto post) with valve 7 connector 6.
NOTE: In case the machine is packed with the post already assembled, pipe C is already connected.
3.3

Electrical connection

THE ELECTRICAL SYSTEM MUST BE SERVICED BY SKILLED ELECTRICIANS ONLY.
Before connecting the machine:
• make sure the power mains rating corresponds to the machine rating as shown on the machine plate;
• check that all power mains components are in good condition;
• check that the electrical system is properly grounded (earth wire must be the same cross-section area as the
largest power supply cables or greater);
• make sure the electrical system of the workshop features an overload/short-circuit cutout set at 30 mA.
Fit a type-approved plug to the machine cable (the ground lead is yellow/green and must never be connected to the
phase leads).
Make sure the electrical system is compatible with the rated power absorption specified in this
manual and apt to ensure that voltage drop under full load will not exceed 4% of rated voltage (10%
upon start-up).
3.4

Direction of rotation of motor (versions with 3 phase motor)

Once all power connections have been made, make sure that the chucking table is rotating in the right direction (pedal
lowered, clockwise rotation). If the direction of rotation is wrong, swap two phase wires in the plug.
FAILURE TO OBSERVE THE ABOVE INSTRUCTIONS WILL IMMEDIATELY INVALIDATE THE
WARRANTY.
3.5

Pneumatic connection

Connect the tyre changer to the workshop compressed air system by means of plug 1 (Fig. 16).
Machine pneumatic feeding system must supply air whose technical characteristics comply with
those listed in Chapter 9 "Technical specifications" and must be equipped with an on-off upstream
valve.
To ensure proper operating pressure, read the value reported by upsteam unit.
Ordinary operating pressure is 10 bars, for specific applications (i.e. weak motorvehicle rims) pressure is best
lowered.
