MOUNTING
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
Check tire and wheel
carefully before 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.
Attempts to force a bead
seat on mis-matched tires
and wheels can cause the
tire to violently explode, causing serious
personal injury or death to operator and/or
bystanders.
Never mount a tire and
wheel handed to you by
anyone without checking
both tire and wheel for damage and
compatibility. Be extra cautious of persons
without 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 14). Do not attempt to service
heavily corroded wheels.
Figure 14 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying close attention
to the beads. Verify size match between tire and
wheel (Figure 14).
3. Lubricate tire beads liberally with tire
manufacturer approved lubricant (Figure 15).
Figure 15 - Lubricate Beads
4. Place tire over wheel and move tower arm into
position. Position tire so that the lower bead is
above the rear extension of the mount/demount
head and below the front knob (Figure 16).
Figure 16- Position Tire Against Mount/Demount Head
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.
Figure 17 - Mounting Top Bead
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 R.H. helper roller, press down
on the tire near the mount head. With L.H.
helper, press down on the tire near the R.H.
roller to hold the tire in the drop center.
NOTE: Move the swirel joint to almost touch
vertical shaft. This will eliminate rubbing of the
tire sidewall by the L.H. helper arm.
The L.H. helper shoe will follow the tire during
rotation. Depress table top pedal and rotate tire
during rotation. Depress table top pedal and
rotate tire until the bead is mounted (Figure 17).
Do not force the tire onto
the rim. Bead damage
could result making the
tire unsafe and/or creating the risk of injury.
N. If table top rotation stalls, reverse the table top
momentarily until the tire bead is again loose on the
wheel. Reposition the tire on the mount head, make
sure the bead is correctly positioned in the drop
center of the wheel, then attempt mounting again.
P. For tube type tires, mount the lower bead first,
move the tower back, install the tube, and then
mount the upper bead.
