12.0 USING THE MACHINE
12.1
Precaution measures during tire removal and fitting
Before fitting a tire, observe the following safety rules:
• rim and tire must always be clean, dry and in good condition; if
necessary, clean the rims and check that:
- neither the bead nor the tread of the tire are damaged;
- the rim does not produce dents and/or deformation (especially
for alloy rims, dents can cause internal micro-fractures, that
pass unobserved at visual inspection, and can compromise the
solidity of the rim and constitute danger even during inflation);
• adequately lubricate the contact surface of rim and the tire beads,
using specific tire lubricants only;
• replace the inner tube valve with a new valve, if the tire tube has
a metal valve, replace the grommet;
• always make sure that tire and rim sizes are correct for their
coupling; on the contrary, never fit a tire unless you are sure it is
of the right size (the rated size of rim and tire is usually printed
directly on them);
• do not use compressed air or water jets to clean the wheels on
the machine.
12.2
Preliminary operations - Preparing the wheel
• Remove the wheel balancing weights from both sides of the wheel.
REMOVE THE VALVE STEM AND ALLOW THE
TIRE TO COMPLETELY DEFLATE.
• Establish from which side the tire should be demounted, checking
the position of the groove.
• Find the rim locking type.
• Try to establish the special types of wheels, such as “EH2” and
“EH2+”, in order to improve locking, bead breaking, assembly and
disassembly performances.
WHEN HANDLING WHEELS WEIGHING MORE
THAN 10 KG (22 lbs) AND/OR WITH A FRE-
QUENCY OF MORE THAN 20/30 WHEELS PER
HOUR, THE LIFTING DEVICE SHOULD BE USED.
12.3
Use of the lifting device
CARRY OUT A DAILY CHECK OF MAINTAINED-
TYPE CONTROLS CORRECT FUNCTIONING,
BEFORE STARTING MACHINE OPERATION.
1. After placing the wheel on the lifting plate (see Fig. 18), press
the lifting device drive pedal (Fig. 19 ref.
_
1) downwards and
bring the wheel to a level where it can be shifted to the chuck
by hand (see Fig. 19).
