Operating Instructions
⚠WARNING
Risk of finger entrapment and laceration.
Wear ANSI Z87.1 compliant protective goggles and equipment.
Ensure the wheel is stable and the work area if free and clear of debris.
Secure and fully support any vehicles.
The bead breaker uses a long stroke and high force. Be careful not to damage or bend rim parts,
like the flange butt weld, when using the bead breaker.
1. Connect the air-driven hydraulic pump to the bead breaker with the hydraulic oil pipe and quick
coupling. Check that all parts are in good condition and
not leaking. Connect the air compressor with the air-
driven hydraulic pump.
2. Unload the truck and lift it with the jack. Have the wheel
in pensile position with strong support on truck, and
release the tire pressure.
3. Hold the bead breaker to the rim, insert the head into
gap between tire rim and detachable side ring. Lock
the screw (part #22) tightly, as indicated in photo.
4. Turn on the air-driven hydraulic pump switch. Place the pump in working position. The push rod in
both sides of breaker will push forward.
5. Continue to push the rod in both sides of the breaker with the pump in working condition, till the
detachable side ring takes off. Pay attention that the stroke of the push rod is 100mm. It is helpful
to extend the product life by stopping operation before the stroke reaches 100mm.
6. Treadle the air-driven hydraulic pump to the oil return and release the pressure. The hydraulic
push rod will be retracted.
7. Take off the bead breaker. Repeat this process around the rim as many times as needed to
completely break the detachable side ring from tire rim.
⚠CAUTION
To prevent damage to the rim, do not use the bead breaker within 12 inches of the flange butt
weld.
1. Apply enough pressure to the bead breaker to completely break the tire bead.
2. Release the hydraulic pressure.
Note: If you have gone all the way around the tire and the tire bead does not break, repeat the steps
in the Activating the Bead Breaker and the Continuing to Break the Tie Bead sections above, with
more hydraulic pressure.
