OPERATION
It is essential that the lock-ring is seated correctly.
Put the wheel assembly into a safety cage and inflate the tyre
●

Visually check the lock-ring is still seated correctly and there
●
is no clearance between it and the loose flange Fig. 3.

●
as the lock-ring may be ejected from the groove resulting in
possible injury.
Deflate the tyre and repeat the procedure.
If the lock-ring is correctly positioned continue to inflate the
tyre to the value given in the previous table.
Before removing the wheel assembly from the safety cage
●
repeat the visual check.
