5.3 Beading the tires
Beading
means the initial grip of the tire bead on the rim,
in order to allow the infl ation operations and subsequent
settling in the seat on the rim.
Safety Precautions:
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.
WARNING:
DO NOT USE THE TIRE CHANGER TO
INFLATE TIRES.
COMPRESSED AIR DEVICES ON THE TIRE CHANGER
ARE ONLY DESIGNED TO FACILITATE THE TUBELESS
TIRE BEADING OPERATION.
NEVER EXCEED THE MAXIMUM PRESSURE ALLOWED
BY THE TIRE MANUFACTURER.
THE OPERATOR MUST STAND CLEAR FROM THE
WHEEL WHEN BEADING THE TIRE, AND PRESSURE
MUST BE MONITORED FREQUENTLY TO AVOID
EXCESSIVE PRESSURE.
BEFORE BEADING, CHECK THE CONDITION OF TIRE
AND RIM.
CHECK FOR CORRECT SEALING BETWEEN THE
VALVE AND THE FITTING AT THE END OF THE
AIR HOSE. AN AIR LEAK CAN GIVE INCORRECT
PRESSURE READINGS AND CREATE SAFETY
HAZARDS
CHECK THAT THE READING ON THE PRESSURE
GAUGE IS “ZERO” WHEN IT IS NOT IN USE.
THE COMPLETE SEATING THE BEAD ON THE RIM IS A
VERY DANGEROUS STAGE OF THE TIRE MOUNTING
PROCEDURE.
TO COMPLETE THE BEADING OPERATION AND
INFLATE THE TIRE CORRECTLY, PLACE IT IN AN
APPROPRIATE TYPE APPROVED CAGE.
A TIRE BURST, WHATEVER ITS CAUSE, CAN RESULT
IN SERIOUS INJURY OR DEATH.
AVOID MOUNTING TIRES THAT ARE 1/2” SMALLER
IN DIAMETER THAN THE RIM, DOING SO FAILS TO
ENSURE THAT THE BEADS ARE SEALED PROPERLY
IN THEIR SEATS: THIS COULD BE A SOURCE OF
DANGER WHEN DRIVING.
