between open sides of frame. Place spade tip
between tire bead and rim flange (fig. 3)
4. Lift ram until trunion engages frame shoulder
and move stop screw into support ram. Apply
pressure to ram and spade by means of pump
until spade has moved tire bead toward center
of rim assembly far enough to permit the placing
of a bead wedge between bead and flange on
Figure 4.
5. Release pump pressure. Remove spade and
ram assembly from frame. Loosen clamping
jaw bolts and remove from flange.
6. Move to spot approximately 90 from first

procedure. Repeat procedure until tire bead is
free.
Four to five applications usually
