Inflating Tubeless Tires - John Bean EHP System IV-E Manuel D'utilisation

4.3-1
4.3 Inflation of tubeless tires
Make sure that both beads are properly lubricated.
WARNING: BEAD SEATING IS THE MOST
DANGEROUS PART OF MOUNTING A TIRE.
IT IS POSSIBLE TO MOUNT TIRES THAT ARE 1/2"
SMALLER IN DIAMETER THAN THE RIM 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.
Inflate tire according to manufacturers recommendations.
WARNING
NEVER EXCEED THE MAXIMUM PRESSURE
AllOWED bY THE TIRE MANUFACTURER.
For safety reasons a quick-inflating valve preset to 4,5
bar is fitted upstream of the pressure gauge for the
pedal-operated inflating device.
THE RIM MUST BE UNCLAMPED WHEN
INFLATING BUT ONLY AFTER 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 TIRE AND RIM.
Due to unusual configurations or the stacking of tires
the inflation process is sometimes difficult.
To assist with this problem the JBC EHP System V is
equipped with bead seater jets incorporated into the
tabletop.
To utilize the bead seater proceed as follows:
A. If possible lock the wheel from inside. Outside
locking reduces efficiency.
NOTE: Use Light alloy rim protector to prevent
any possible damage to the rim when
operating on light alloy rims.
b. Connect the inflation hose to the valve stem.
C. Lift the tire with both hands so that upper bead is
sealed to the rim edge (Fig. 4.3-1).
D. Press the inflation pedal down swiftly. The top bead
is already sealed by the lifting motion. The air from the
bead seater jets will rebound into the bottom sidewall
driving it into place and creating a seal.
ATTENTION!
WHEN OPERATING THE bEAD SEATER WEAR
SAFETY ATTIRE TO AVOID INJURY TO bODY OR
EYES.
E. Complete inflation to manufacturer's suggested
pressure. Never exceed pressure listed on tire sidewall.
