Tyre Inflation
T3-010_2
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.
!M
WARNING
An exploding tyre can kill. Inflated tyres can explode if
over-heated or over-inflated. Follow the instructions
given when inflating the tyres. Do not cut or weld the
rims. Use a tyre/wheel specialist for all repair work.

moving them.
Store with care to ensure that they cannot fall and
cause injury.

fitted on the machine or installed in a tyre inflation
cage.

Prepare the equipment.
a
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. For recommended tyres and
pressures for your machine, see
Tyre Sizes and
Pressures
.
b
Use an air hose fitted with a self-locking air chuck
and remote shut-off valve.
3
Add the air.
a
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.
b
Inflate the tyre to the recommended pressure. Do
not over-inflate.

Checking the Wheel Nut Torques
!M
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.
2-3-2-8
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.
