than on the breaker side, the fluid return ball is lifted
off the seat and the breaker rod retracts in Step 4.
Retraction is due to an internal spring and pressure

tongue.
The

rod
retracts first, followed by the clamping rod.
The

is
capable

on the rim before allowing the bead breaking action.
Do not continue to operate the air/hydraulic pump
once

is
completely
extended.
Failure
