4.4 INFLATION OF TUBELESS TIRES

Make sure that both beads are properly lubricated.
BEAD SEATING IS THE MOST DANGEROUS PART
OF MOUNTING A TIRE.
NEVER STAND OVER TIRE WHEN ATTEMPTING
TO SEAT BEADS OR DURING INFLATION
IT IS POSSIBLE TO INCORRECTLY MOUNT TIRES
THAT ARE 1/2" SMALLER IN DIAMETER THAN
THE RIM THAT THEY ARE MOUNTED ON. WHILE
THESE BEADS WILL SEAL, IT IS IMPOSSIBLE TO
GET THEM TO SEAT IN THEIR PROPER POSITION.
EXPLOSION OF A TIRE MAY CAUSE SEVERE
INJURY
SAFETY RESTRAINT ARM (OPTIONAL) MUST BE
IN PLACE PRIOR TO ATTEMPTING BEAD SEATING
OR INFLATION.
NEVER EXCEED THE MAXIMUM PRESSURE
ALLOWED BY THE TIRE MANUFACTURER.
IF YOU CLAMPED THE RIM FROM THE OUTSIDE
IT MUST BE UNCLAMPED WHEN INFLATING BUT
ONLY AFTER THE SRA IS IN PLACE.
THE OPERATOR MUST STAND CLEAR FROM THE
WHEEL WHEN INFLATING, AND PRESSURE MUST
BE MONITORED FREQUENTLY TO AVOID OVER
INFLATION.
BEFORE INFLATING A TIRE, CHECK THE
CONDITION OF THE TIRE AND THE RIM.

recommendations.
Due to unusual confi gurations or the stacking of tires
the infl ation process may be diffi cult. To assist with
this problem the Tire Changers are equipped with bead
seater jets integrated into the tabletop.
To utilize the bead seater proceed as follows:
A. Position the safety restraint arm (optional) over
center of wheel assembly. The safety arm is lifted
upward by grasping the safety restraint position knob
and lifting upward while simultaneously depressing
the anti-rotation lock arm. Swing SRA arm assembly
so the rubber retainer is centered over the rim. Note
that air pressure to the infl ation hose will not fl ow until
the arm is centered over the rim.
B. Connect the infl ation hose to the valve stem.
C. Lift the tire with both hands so that the upper bead
is sealed to the rim edge (Fig. 4.4-1).
NEVER STAND OVER TIRE WHEN ATTEMPTING
TO SEAT BEADS OR DURING INFLATION
Fig. 4.4-1
D. Press the infl ation pedal down swiftly to the end of its
travel to activate the bead seater jets. (Fig. 4.4-1 item 1).
The top bead is already seated by the lifting motion.
Therefore, the air from the bead seater jets will enter
the tire impacting on the top sidewall and rebound into
the bottom sidewall driving it into place and seating the
bead, creating an air seal.
WHEN OPERATING THE BEAD SEATER, ALWAYS
WEAR SAFETY GLASSES TO AVOID INJURY TO EYES.
E. Install valve core, if removed. Complete infl ation to
manufacturer's suggested pressure. Never exceed
pressure listed on tire sidewall.
