Beading the tyres

Beading means the initial grip of the tyre bead on
the rim, in order to allow the infl ation operations and
subsequent settling in the seat on the rim.
Safety Precautions:
WARNING: DO NOT USE THE TYRE CHANGER TO
INFLATE TYRES.
THE COMPRESSED AIR DEVICES ON THE TYRE
CHANGER ARE ONLY DESIGNED TO FACILITATE
THE TUBELESS TYRE BEADING OPERATION OR
THE SETTLEMENT OF THE TUBE, BASED ON THE
TYPE OF WHEELS.
NEVER EXCEED THE MAXIMUM PRESSURE
SPECIFIED BY THE TYRE MANUFACTURER.
THE OPERATOR MUST STAND SAFELY CLEAR
FROM THE WHEEL WHEN BEADING THE TYRE,
AND PRESSURE MUST BE CHECKED FREQUENTLY
TO AVOID EXCESSIVE PRESSURE.
BEFORE BEADING, CHECK THE CONDITION OF
TYRE 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 OF THE BEAD ON THE
RIM IS A VERY DANGEROUS STAGE OF THE TYRE
MOUNTING PROCEDURE.
TO COMPLETE THE BEADING OPERATION AND
INFLATE THE TYRE CORRECTLY, PLACE IT IN AN
APPROPRIATE TYPE-APPROVED CAGE.
A TYRE BURST, WHATEVER ITS CAUSE, CAN
RESULT IN SERIOUS INJURY OR DEATH.
AVOID MOUNTING TYRES THAT ARE 1/2"
SMALLER IN DIAMETER THAN THE RIM, BECAUSE
OTHERWISE IT IS NOT POSSIBLE TO ENSURE
THAT THE BEADS ARE SEALED PROPERLY IN
THEIR SEATS: THIS COULD BE A SOURCE OF
DANGER WHEN DRIVING.
