Use dry nitrogen (N2) gas for all pneumatic tires.
Nitrogen will not burn inside the tire.
Correct nitrogen inflation (charging) equipment
and training in its use are needed to prevent too
much pressure in a tire. A tire blowout or rim
failure can result from equipment that is not
correct or is not correctly used.
Also, the use of nitrogen instead of air in the tires,
decreases the amount of tire deterioration. This is
especially important for tires that have an expected long
service life (4 or more years). It also decreases
The pressure of a fully charged nitrogen cylinder is
approximately 15 000 kPa (2200 psi). This high
pressure can cause a tire blowout and or rim failure if the
charging equipment is not used correctly. See Tire
Inflation (Charging) With Nitrogen.

Servicing and changing tires and rims can be
dangerous. This work must be done only by
procedures. If correct procedures are not followed
while servicing tires and rims, the assemblies can
burst with explosive force and cause serious
physical injury or death. Follow carefully the
specific information provided by your tire servicing
man or dealer.
When tires are changed be sure to clean all rim parts.
If necessary, paint the components to prevent corrosion.
Sand blasting is recommended for removal of rust.
Check all components carefully and replace any cracked,
badly worn, damaged, severely rusted or corroded parts
with new parts
of the same size and type. If there is any doubt, replace
with new parts. Never rework, weld, heat or braze any
The tires on these machines are inflated (charged)
with nitrogen instead of air. The recommendation is that
nitrogen be used for pressure adjustments in a tire. See
your tire dealer for the correct tire pressures for job
conditions and for any questions on nitrogen inflation.
CORRECT POSITION FOR TIRE INFLATION
(Behind the Tread)
A tire blowout or rim failure can occur during tire
inflation. To prevent possible injury get next to
(behind) the tread, as shown, when inflating a tire.
equipment at no more than 140 kPa (20 psi) over
the correct tire pressure.
Use only the 6V4040 Nitrogen Tire Inflation Group
to inflate tires from a nitrogen gas cylinder. See
Special Instruction, Form Number SMHS7867 for
tire inflation instruction.
Use the same tire pressures for nitrogen inflation
that are used for air inflation. See the Operators
manual for the shipping and operating pressures.
