4.3 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
OR DEATH.
Infl ate tire according to manufacturers recommendations.
SAFETY RESTRAINT ARM MUST BE IN PLACE PRIOR
TO ATTEMPTING BEAD SEATING OR INFLATION.
NEVER EXCEED THE MAXIMUM PRESSURE ALLOWED
BY THE TIRE MANUFACTURER.
THE RIM MUST BE UNCLAMPED WHEN INFLATING BUT
ONLY AFTER THE BEADS HAVE BEEN SEATED.
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.
Due to unusual confi gurations or the stacking of tires the
infl ation process may be diffi cult. To assist with this problem
the JBC EEWH553A Tire Changers are equipped with bead
seater jets integrated into the table top.
To utilize the bead seater proceed as follows:
A. Position the safety restraint arm over center of wheel
assembly. The safety arm is lifted upward by grasping the
safety restraint position knob and lifting upward while simulta-
neously depressing the anti-rotation lock arm. Swing safety
arm assembly so the circular 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. If possible lock the wheel from inside. Outside locking
reduces effi ciency.
C. Connect the infl ation hose to the valve stem.
D. Lift the tire with both hands so that the upper bead is
sealed to the rim edge (Fig.21).

ATTEMPTING TO SEAT BEADS OR DURING INFLATION

E. Press the infl ation pedal down swiftly to the end of its travel
to activate the bead seater jets. (#6 Fig.10)
The top bead is already sealed by the lifting motion. There-
fore, 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 creating a seal.
WHEN OPERATING THE BEAD SEATER, ALWAYS WEAR
SAFETY GLASSES TO AVOID INJURY TO EYES.
F. Install valve core, if removed. Complete infl ation to manu-
facturers suggested pressure. Never exceed pressure listed
on tire sidewall.
5.0 DEMOUNTING TUBE-TYPE TIRES
A. For breaking the bead operate as described for the tube-
less tires in section 4.1.A to 4.1.F.
In this case the valve is part of the tube.
NOTICE!
BE CAREFUL NOT TO DAMAGE THE TUBE DURING THE
BEAD-BREAKING OPERATION. THE VALVE SHOULD
BE OPPOSITE TO THE BLADE OF THE BEAD BREAKER.
B. To demount the fi rst bead, place the valve at 2 o’clock
position.
NOTICE!
BE CAREFUL NOT TO CATCH THE TUBE WITH THE
MOUNT/DEMOUNT TOOL, WHEN LIFTING THE BEAD
ON THE MOUNTING FINGER.
After demounting the fi rst bead carefully, remove the tube
before demounting the second bead, as described in sec-
tion 4.1.
