Inflating the Tyres
!!
WARNING
Over-inflated or overheated tyres can explode. Do not
cut or weld the rims. Get a tyre/wheel specialist to do
any repair work.

These instructions are for adding air to a tyre which is
already inflated. If the tyre has lost all its air pressure, call in
a qualified tyre mechanic. The tyre mechanic should use a
tyre inflation cage and the correct equipment to do the job.
1 Prepare the Wheel
Before you add air to the tyre, make sure it is correctly
fitted on the machine or installed in a tyre inflation cage.
2 Prepare the Equipment
Use only an air supply system which includes a
pressure regulator. Set the regulator no higher than
1.38 bar (20 lbf/in
2
) above the recommended tyre
pressure. (See Table below).
Use an air hose fitted with a self-locking air chuck and
remote shut-off valve.
3 Add the Air
Make sure that the air hose is correctly connected to
the tyre valve. Clear other people from the area. Stand
behind the tread of the tyre while adding the air.
Inflate the tyre to the recommended pressure. Do not
over-inflate.
Tyre Table
Renewing Segments of Optional
Non-Inflatable Tyres
Non-inflatable tyres are available as an option. These tyres
consist of a number of individual segments bolted to the
wheel rim.
Damaged segments can be renewed individually. Loosen
and remove the four nuts and washers A (two each side of
the wheel). Lift the segment clear by extracting its fixing
studs from the holes in the wheel rim.
Fit a new segment in reverse order to removal, then tighten
the retaining nuts to a torque of 28 Nm (21 lbf ft, 3 kgf m).
Checking the Wheel Bolt Torques
On new machines, and whenever a wheel has been
removed, check the wheel bolt torques every two hours until
they stay correct.
Every day, before starting work, check that the wheel bolts
are tight.
The correct torques are shown in the table below.

WARNING
If, for whatever reason, a wheel bolt is renewed, all the
bolts for that wheel must be changed as a set, since the
remaining bolts may have been damaged.
