Adjustments of the hinges of the tool
holding arm
In case it is necessary to regain clearances, or after re-
placement of some items, the hinges of the tool holding
arm can be adjusted by means of the appropriate cam
adjusters.
In case operate as follows.
1.
Power off the machine;
2.
Loosen the locking counter-nuts on both sides of the
hinges;
3.
By means of the key operate on the adjustment cams
on both sides until all clearances are completely
regained;
4.
Try hooking and unhooking of the tool on several
points on the length of the trolley;
5.
Eventually repeat the previous operations if neces-
sary;
6.
Tighten the counter-nuts.

3.7
Three-phase electrical system
The electrical system that is being used is protected by
fuses and thermal-magnetic circuit breakers, so, in case
of malfunctions, always disconnect the tyre changer
from the power network.
Description and function of the components:
3.7.1
Q1 - main switch
In normal operating conditions has to be set on 1 ON.
This device powers up or off the entire electrical circuit.
3.7.2
F1, F2, F3 - protection fuses of the whole
high-tension circuit
Allow power supply to the main circuit of the tension
transformer and to the motor of the rotation mandrel.
3.7.3
Q3 - thermal-magnetic motor protector for the
protection of the motor and of the hydraulic
pump
If activated, check the connections of the motor, its
energy absorption and the correct calibration of the
device according to the characteristics of the motor.
3.7.4
F4 and F5 - protection fuses of the primary
circuit of the tension transformer (T 100VA)
If the fuses burn, usually because of a tension surge,
power supply will be missing to all the low-tension
circuit, both 24VDC and 24VAC, so nothing will work
except for the hydraulic pump.
3.7.5
F6 - protection fuse of the low-tension 24VDC
circuit
In case this one blows all the hydraulic motion won't
work, all other will remain active like the mandrel rota-
tion. Check that the connection cable of the pedal box
is not damaged and that the cables inside are not inter-
rupted or short-circuited. Rare, but in any case possi-
ble, check the electromagnetic coils of the electrovalves
or the micro switches on the pedal box that can short-
circuit if damaged.
