MOUNTING
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
Check tire and wheel
c a r e f u l l y b e f o r e
mounting. Make sure
the tire bead diameter and wheel diameter match
exactly. Consult the
Rubber Manufacturer's
Association for approved rim widths for tire
sizes. Mis-matched tires and wheels explode.
Never Mount a tire
and wheel handed to
you by anyone with-
out checking both tire and wheel for damage and
compatibility. Be extra cautious of persons with-
out knowledge of tire service. Keep by-standers
out of service area.
Never mount a damaged
tire. Never mount a tire
on a rusty or damaged
wheel. Damaged tires and/or wheels may explode.
If you damage the
tire bead during
mounting, STOP!,
remove the tire and mark it as damaged. Do not
mount a damaged tire.
1. Inspect the wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber
residue (Figure 12). Do not attempt to service
heavily corroded wheels.
Figure 12 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying close attention
to the beads. Verify size match between tire and
wheel (Figure 12).
3. Lubricate tire beads liberally with tire manufac-
turer approved lubricant (Figure 13).
Figure 13 - Lubricate Beads
4. Place tire over wheel and move swing arm into
position. Position the tire so that the lower bead
is above the rear extension of the
mount/demount head and below the front knob
(Figure 14).

5. Depress table top pedal and rotate the wheel to
mount the lower bead. Use the drop center of
the wheel to reduce the tensional force on the
bead by pressing down on the tire directly
across from the mount head.Rotate table top
until lower bead is fully mounted.
6. For top bead, rotate the table top until the valve
stem is directly across from the mount head. Lift
the upper bead up and over the rear of the
mount head. With your left hand press down on
the tire between the mount head and the valve
stem to hold the tire in the drop center. Depress
the table top pedal and rotate the tire until the
bead is mounted. Continue to press down on
the tire during the remaining mounting process.
Do not force the tire
onto the rim. Bead
damage could result
making the tire unsafe and/or creating the risk of
injury.
NOTE: If table top rotation stalls, reverse the table
top momentarily until the tire bead is again loose on
the wheel. Reposition the mount head, make sure
the bead is correctly positioned in the drop center of
the wheel, then attempt mounting again.
NOTE: For low profile or stiff sidewall tires, it may be
advantageous to use the bead lifting tool to initially
hold the upper bead down in the drop center, or use
drop center tools as shown in Figure 30, page 11.
NOTE: For tube type tires, mount the lower bead
first, move swing arm out, install the tube, and then
mount the upper bead.
When you have completed the mounting
process, proceed to Inflation, page 7.
