Warning, Danger – COATS 6060 AX/EX Tire Changer User Manual

T. If tire and wheel are properly lubricated and
operator cannot achieve bead seal after 3 or 4
attempts, the valve core may be removed from the
valve stem to allow more air flow into the tire to
assist with bead seal. After bead seal is achieved,
remove the chuck and reinstall the valve core.
Bead Seating
Operator should always stand
behind Inflation Guard and keep
hands, arms, and entire body
away from the tire during the remaining bead seat and
inflation procedures. Do not permit anyone to stand over the
tire as personal injury could result.
Operating a tire changer with a
defective, improperly adjusted,
or by-passed pressure limiter
could cause an operator to accidentally over-pressurize a
tire, resulting in a tire explosion with severe injury or death
to the operator or bystanders. Always be sure that the
pressure limiter is present and is operating properly on the
machine at all times.
NEVER increase air pressure to
exceed 40 PSI when attempting
bead seat. If operator is unable
to obtain bead seat, something is wrong. Deflate tire
completely, inspect the tire and wheel for defects and make
sure that the tire and wheel size match. Correct any
problems found, relubricate both tire beads, and reattempt
bead seal and seating procedures.
1.
Once the tire is sealed to the rim, move to the
area behind the Inflation Guard and push the
inflation valves simultaneously. Both valves
must be actuated to inject air into the tire.
Continue to inject air into the tire in short
intervals, checking the pressure frequently.
Stand behind Inflation Gaurd during bead seat.
Keep hands, arms, and entire body away from
tire during this procedure.
Tire beads should move outward and "pop" into
their bead seat position as pressure inside the
tire increases. If this does not happen, a
problem exists. Investigate carefully for defects
and make sure the tire and wheel sizes match.
Check tire pressure frequently.
Never exceed 40 PSI while
seating beads. 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, stay behind the Inflation Guard and keep hands, arms,
and entire body away from inflating tire. An 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.
Inflation
NEVER exceed tire
manufacturer's recommended
air pressure. Tires can explode,
especially if inflated beyond these limits. Stay behind
Inflation Guard and keep hands, arms, and entire body back
from inflating tire. Avoid distraction during inflation. Check
tire pressure frequently to avoid over inflation. Excessive
pressure can cause tires to explode, causing serious injury
or death to operator or bystander.
1.
Make sure both beads are seated. When both
beads are seated, the tire is ready for inflation.
2.
Replace the valve core if it was removed.
3.
Depress inflation valves simultaneously and
hold to inflate tire. Pressure limiter will cycle the
air flow as described earlier. On most passenger
car tires, the pressure limiter will cease air flow
at approximately 60 PSI. On smaller volume
tires the pressure may be higher.
U. Release air pressure from tire by pressing the
manual release valve button (inflation hose must be
attached to the valve stem, Figure 18).

WARNING
Explosion Hazard
Never exceed 40 PSI
while seating beads.
Explosion Hazard
Never inflate tire
above manufacturer’s
recommended
pressure after bead is
seated.

IMPORTANT: When inflating tires that require more than 60 PSI, always use a safety cage and an air hose with
a clip-on air chuck and an in-line valve. The hose must have enough length between the chuck and the
operator/in-line valve to allow the operator to stand outside the trajectory.
