Principal Operating Parts
4 • COATS Heavy Duty Tire Changer
Operating Instructions
Tubeless Tire Bead Loosening
Remove the valve core and allow tire to deflate com-
pletely. Remove all weights from wheel.
3. For most tires, one operation of the bead loosener
shoes will loosen both beads. However, some difficult
tires on rusty rims may require an additional operation
to loosen the second bead. Here are three methods
that can help loosen the second bead.
1. Install rim stop in the appropriate position for tube-
less tires. See illustration.
Position tire between bead loosener shoes: short drop
center side toward shoe with rim stop.
WARNING
Do not place any part of body between bead
loosening shoes while machine is running.
2. Adjust shoes and loosen beads: using handle,
adjust bead loosener shoes on tire sidewalls 1/4-inch
from rim contour. Depress left side of foot pedal to
loosen beads. Depress right side to retract shoes. Note:
for handling several wheels of the same size, an adjustable stop is provided for convenience. (See arrow.)
Spin Wheel: Retract shoes completely. Roll wheel
back, spin 180 degrees and loosen opposite side as in
step 2 above.
Roll Wheel: Retract shoes completely. Roll wheel
forward firmly against the rollers and rotate it to a new
position. Reposition and loosen bead as in step 2 above.
CAUTION
Never allow both bead loosening shoes to
contact rim, since this could cause rim damage.
Angle Tire: (not recommended for aluminum rims) The
shoe with the rim stop may itself be used as a rim stop.
Angle the wheel so that this shoe contracts the rim and
the opposite shoe contacts the unloosened bead.

4. Disengage bead loosener shoes and turn tire 90
WARNING
degrees and repeat steps 1, 2, & 3 until bead is loosened.
Allowing both shoes or one shoe and the
rim stop to contact the rim during bead loosening may cause rim damage.
Multiple Piece Rim Bead Loosening
CAUTION
Before attempting to loosen beads, remove
the valve core and be sure the tire is completely deflated. Do not place any part of the
body between bead loosener shoes.
1. Place rim stop in tube type tire position; see illus-
tration.
5. Use bead loosener shoes to hold tire and remove
lock ring.
6. To loosen other bead, remove wheel assembly
from between the shoes and pivot tire 180 degrees
to position the ring side of the wheel near rim stop.
Repeat steps 2, 3, and 4 above.
WARNING
Always inflate tires inside a safety inflation cage. Tire explosion during inflation can
cause serious injury or death.
Clamping
2. Position tire between bead loosener shoes with
the ring(s) toward the kicker shoe.
Position bead loosener shoe with 1/4" of lock ring.
CAUTION
Do not let shoes push on rim or lock ring(s).
Rim or rings may become warped and damaged.
3. Actuate bead loosener so that the bead loosener
shoe pushes bead in. As the kicker shoe passes the
ring, pull handle to bring the kicker shoe up to the bead.
Continue to full stroke of bead loosener.
1. Raise working table: Raise working table to almost
vertical position by pulling back on the control handle.
Open clamps by twisting the control handle counterclockwise.
2. Clamp Adjustment: Adjust all three clamps to the
proper wheel diameter range. The front hole position
is for 19.5" to 24.5". The rear hole position is for 16" to
19.5".
6 • COATS Heavy Duty Tire Changer
3. Position Wheel: Roll wheel onto the safety skirt as
close to the working top as possible. Position rim flange
into the lower clamp.
Aluminum Wheels: Many aluminum wheels are
designed for the tire to be mounted from either side.
For these wheels it is recommended to clamp with
the disc side down. However, if the wheel does have
a short drop center side, it should always be clamped
with this side up.
5. Lubricate both beads thoroughly: Both beads and
the rim flange should be thoroughly lubricated with an
approved tire lubricant before attempting to demount
the tire. It may be easier to lubricate the bottom bead
while the tire is in the bead loosener.
4. Clamp Rim: With the left hand on the top front of
the rim, push the rim toward the upper two clamps.
Then close the clamping jaws by twisting the control
handle clockwise. Observe the clamping action to make
sure all three clamps are properly engaged. Lower
working table to desired angle by pushing forward on
control handle.
CAUTION
Make sure the short drop center side of the
wheel is toward the operator. Attempting to
demount tire from the long drop center side
may damage the tire bead.
Demounting
1. Install Mount/demount Tool: Insert mount/demount
tool in square drive socket and position tool head on the
rim flange. Rotate the tool head to approximately a 12
o’clock position by depressing either foot pedal.

CAUTION
Always demount by rotating tool clockwise.
5. Remove Tire: The demounted tire can now be
removed. On heavier tires raising the working table will
help lift the tire to a vertical position.
Mounting
1. Before mounting tire on a used rim, be sure
flange area (particularly the bead seat area) is clean and
smooth. Remove any buildup of rust, corrosion or old
rubber with wire brush.
CAUTION
3. Demount Top Bead: Holding the bead lifter down
as shown, depress the front side of either foot pedal
thus rotating the tool head clockwise and demounting
the top bead. Make sure mount/demount tool does not
rotate into bead lifter during the operation.
4. Demount Bottom Bead: Return mount/demount
tool to the 12 o’clock position and insert bead lifter
under bottom bead to the left of head. Again, make sure
the opposite side of the bottom bead goes into drop
center. Lift bottom bead over tool blade. Hold the bead
lifter mount/demount tool clockwise and demounting
bead. Make sure tool does not rotate into bead lifter
during the operation.
Never mount a tire on a rim where any parts
show cracks, damage, or have been repaired
by welding or brazing. Thoroughly inspect
inside of casing for damage or foreign material. Make sure that the tire is completely dry,
as moisture deteriorates the cord fabric of the
tire and may result in eventual failure of the
tire. Lubricate both beads with an approved
rubber lubricant. Never use silicones, antifreeze, or petroleum base solutions.
