WARNING
To avoid personal injury and property damage,
never stand or sit in front of a mounted tyre
during tyre inflation. Use a clip-on air chuck
with a long hose and stand to one side while
the tyre is being inflated.
WARNING
To prevent personal injury and property
damage, always prevent flammable vapours
that could produce tyre explosions, from
being pumped into tyres during inflation, by
observing the following precautions:
A.
Use an air compressor and reservoir located
inside a heated building, when available, so
that alcohol, methanol, or other flammable
antifreeze liquids are not needed in the air
tanks to prevent moisture freezing in the tank
and lines in subfreezing temperatures.
B.
Make sure that paints, lacquers, paint
thinners, or similar materials that produce
volatile, flammable vapours are not used or
stored near the air intake of the compressor
that supplies the air for inflating tyres. The
compressor should be isolated from all such
sources of flammable vapours.
C.
Be sure to thoroughly flush and blow off all
flammable solvents used for cleaning the air
compressor inlet screen before using the
compressor for tyre inflation, or any other
purpose.
D.
Do not charge batteries, either in or out of a
machine, near the air inlet of a compressor
used for inflating tyres. Charging batteries
produces highly explosive hydrogen gas which
can be readily drawn into a nearby
compressor inlet and pumped into the tyre.
E.
Never exceed the specified concentration of
alcohol when adjusting the alcohol vaporiser,
or adding alcohol to the auxiliary air tank,
used on machine air systems to prevent
freezing or moisture condensate in below-
freezing temperatures. Excessive alcohol,
added to the machines air tanks in this
manner can produce flammable vapours that
will be pumped into a tyre when this air supply
is used for tyre inflation if the tyre inflation kit
is not equipped with a moisture filter. Alcohol
added to machine air systems in

Fig. 7 - Typical Safety Cage
WARNING - Continued
recommended concentration to prevent
condensate freezing are below hazardous
levels for tyre inflation.
F.
Another source of hazardous flammable
vapours in tyres is the tyre bead lubricant.
Always use bead lubricants that do not
introduce flammable vapours into the tyre.
Inflation
Note: Always use tyre inflation equipment with an air
filter that removes moisture from the air supply, when
available, to prevent moisture corrosion of internal
rim parts.
1. If the tyre is off the machine, it should be placed in
a safety cage before inflating. See Fig. 7.
2. Inflate all tyres with ratings of 16-ply and above to
5.2 bar (75 lbf/in²) to seat beads and seal 'O' ring,
then adjust to the recommended pressure.
3. For recommended operating air pressure, refer to
the chart under the heading, 'Tyre Inflation
Pressures'.
