OPERATION
BEAD BREAKING
Lubricate the breaker handles before breaking the bead to avoid wear and tear.
1. Completely deflate the tire. Remove the valve
stem core to speed up this process.
2. Place the tire rim on the base’s triangular
wedge to hold it in place.
3. Set the bead breaker foot (#5) against the
edge of the tire’s rim.
a. It may be necessary to adjust the height
of the bead breaker receiver by
removing the lock pin (#8), adjusting the
receiver location in the bracket and
reinserting the lock pin.
4. Push down on the handle (#11) to separate the bead from the rim.
5. If the bead does not come off all at once, it may be necessary to turn the
tire and repeat the procedure in several locations. You may be able to push
down with your hands or feet to complete the bead separation.
6. Turn the tire over and repeat the above steps.
CLAMPING THE TIRE RIM
1. Adjust each fixed jaw clamp so it is approximately the correct distance to
accommodate the rim (Fig. 6).
2. Place the rim onto the fixed jaw so it rests in the hooks. The tire stem
should be on the topside.
3. Hold the rim up and turn the T-handle (#13) until the moveable jaw clamp
(#17) is resting against the rim (Fig. 7).
4. Insert either the small (#2) or large post (#3) into the receiver at the center
of the spider arms. Each post has two diameters (see Specifications). Use
the post that is appropriate for wheel’s axle opening.
