SECTION 02 - SAFETY PRECAUTIONS 11
Tyres and wheels
Always check that inflating pressure of tyres corre-
sponds to the prescribed value suggested by Manu-
facturer and check periodically its integrity.
If the inflating pressure of tyres has to be changed,
carry out this operation keeping at a safety distance.
The tyres inflating pressure has always to be ck-
ecked with no load and in cold conditions. Never use
reconditioned discs wheel as eventual weldings,
heat treatments or brazings not executed correctly
can weaken the wheels and be therefore cause of
successive damages or faults.
Do not perform torch cutting or welding operations
on rims with tyres installed. The spare tyre should
be inflated only as far as needed to hold the ring
parts together: remember that when not installed on
the disc, a tyre inflated to maximum pressure can
explode.
When working on tyres, lock previously all wheels
front and back ones. After lifting machine with hy-
draulic jack, prevent its falling down inserting sup-
ports according to the safety regulations in force.
Deflate the tyres before removing them.
Before extracting possible foreign bodies jammed in
the tread, it is necessary to deflate tyres.
Do not inflate tyres with flammable gas: they may
cause explosions and serious personal injuries.
At the end of work shifts check for loose screws and/
or rims mounting brackets, if necessary carry out
their tightening according to the instruction given in
this issue.
