Inflation H–3
Bead Seating –Safety Cage for EMT/RunFlat Tires
Operator should keep hands, arms, and entire body away
from the tire during bead seat and inflation procedures.
Do not stand over the tire as personal injury could result.
Always use a safety cage to bead seat and inflate
EMT/RunFlat tires. Never exceed 80 PSI to seat beads on
EMT/RunFlat tires. If operator is unable to obtain bead
seat, something is wrong. Deflate the tire completely,
inspect both the tire and wheel, correct any problems found,
relubricate both tire beads, and reattempt bead seal and
bead seat procedures. Follow all safety instructions in this
manual and on the machine.
You must inspect all wheels and tires prior to inflation
for condition or improperly matched wheels/tires.
Damaged or improperly matched wheels/tires may fail
upon inflation. Portions of a damaged or improperly
matched wheel/tire may not be restrained by a tire safety
cage resulting in injury or death.
1 Once tire pressure is indicated on the air gauge, remove
the tire/wheel from the tire changer, reinstall the valve
core (if it was removed), and place the assembly in an
approved safety cage.
Stand back during bead seat. Check the pressure frequently.
Keep hands, arms, and entire body away from safety cage
and tire during this procedure.
Tire beads should move outward and “pop” into their bead
seat position. If this does not happen, a problem exists.
Investigate carefully.
Check tire pressure frequently. Never exceed 80 PSI
while seating beads on EMT/RunFlat tires. Once seated,
never exceed tire manufacturer’s recommended air
pressure. Tires can explode, especially if they are inflated
beyond their limits. At all pressure levels when inflating
through the valve stem, keep hands, arms, and entire body
away from inflating tire. An unrestrained exploding tire,
wheel, or bead sealing equipment may propel upward and
outward with sufficient force to cause serious injury or
death to operator or bystander.
2 Use an air hose equipped with a remote pressure gauge and
valve. The air hose should be of sufficient length to allow the
operator to move a safe distance away from the cage.
Stay out of the trajectory as indicated by dotted area.
3 Apply air pressure to the tire in short bursts, checking
the air pressure in the tire in between bursts. Exercise
caution as the air pressure increases. Attempt to seat the
beads with minimum air pressure.
Once the beads “pop” into their seated position, stop the air
flow to the tire immediately.
