Tyre Inflation

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.
! WARNING
An exploding tyre can kill, inflated tyres can explode if
overheated. Do not cut or weld the rims. Use a
tyre/wheel specialist for all repair work.

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 psi) above the recommended tyre
pressure. See Section F, Technical Data for
recommended tyres and pressures for your machine.
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.

Checking the Wheel Nut Torques

On new machines, and whenever a wheel has been
removed, check the wheel nut torques every two hours until
they stay correct.
Every day, before starting work, check that the wheel nuts
are tight.
The correct torques are shown in the table below.
Front - Nm lbf ft

Rear - Nm lbf ft

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