14.
With the tire in position (note that the valve stem
is under the Duckhead tool), rotate lever down to posi-
tion the bead on top of the Duckhead tool. Depress the
foot pedal to rotate the tire. The Duckhead mount/de-
mount tool will guide the lower tire bead off of the rim.
Note
With tube-type tires, demount the upper bead
and remove the tube before demounting the lower
bead.
Note
After successfully completing the demount pro-
cess, proceed to MOUNTING.
Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
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.
Check tire and wheel carefully before
mounting. Make sure the tire bead diameter
and wheel diameter match exactly. Consult
the Tire Guide and/or Rubber Manufactur-
er’s Association for approved rim widths for
tire sizes.
Never mount a damaged tire. Never mount
a tire on a rusty or damaged wheel. Dam-
aged tires and/or wheels may explode.
When in doubt do not mount.
Never mount a tire and wheel handed to
you by anyone without checking both tire
and wheel for damage and to be certain the
sizes match. Do not let untrained persons
operate tire changer and keep bystanders
out of service area.
Forcing the tire onto the rim can cause bead
damage. If you damage the tire bead during
mounting, STOP!, remove the tire and mark
it as damaged. Do not mount a damaged
tire.
1.
Before any mounting, inspect the tire for damage
and verify size match between tire and wheel (fi g. 14).
Figure 14 - Verify Size Match Between Tire and Wheel
2.
Inspect the wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber residue
(fi gure 15). Do not attempt to service a heavily corroded
wheel, damaged wheel, or bent wheel.
