4.3 Infl ation 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.
Infl ate tire according to manufacturers recommendations.
WARNING
NEVER EXCEED THE MAXIMUM PRESSURE
ALLOWED BY THE TIRE MANUFACTURER.
For safety reasons a quick-infl ating valve preset to 4,5
bar is fi tted upstream of the pressure gauge for the
pedal-operated infl ating device.
THE RIM MUST BE UNCLAMPED WHEN
INFLATING BUT ONLY AFTER BEADS HAVE
340a.tif
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 confi gurations or the stacking of tires
the infl ation process is sometimes diffi cult.
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 effi ciency.
NOTE: Use Light alloy rim protector to prevent
any possible damage to the rim when
operating on light alloy rims.
B. Connect the infl ation 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 infl ation 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 infl ation as described at §4.3.A.
