OPERATING INSTRUCTION
BEAD LOOSENING AND DEMOUNTING
Remember to remove all weights from both sides of the
wheel. Weights left on the back side of the wheel may cause
the wheel to be clamped un-level. This may result in the
combination mount/demount head contacting the rim
causing scratches. On alloy wheels, always rotate the wheel
one turn after setting the head to insure proper wheel
chucking.
Always review nicks and scratches with owners of
expensive wheel and tire combinations prior to servicing.
Review the performance wheel section of this manual
prior to servicing performance tire/wheel combinations.
1. Deflate tire completely by removing the valve core from
the valve stem. (See Fig. 1).
2. The clamps on the table top may extend beyond the table
top itself. To avoid damaging the clamps and/or wheel,
move the clamps to their full inward position before
positioning a tire for bead loosening.
3. Always loosen the bead on the narrow side of the wheels
drop center first. ( See Fig. 4 for better description of the
drop center.)
4. Use extra care in positioning the bead breaker shoe on
larger wheels/tires, and on alloy wheels. Make sure the
shoe rests next to but not on the rim, and not on the tire
sidewall.
5. Pull the bead breaker shoe away from the machine and
roll the wheel into position. The valve stem should be in the
2 o’clock position.
6. Position the bead breaker shoe against the tire next to,
but not on, the rim. Press the breaker pedal to actuate the
shoe and loosen the bead. It may be necessary to loosen
the bead in multiple locations around the tire. (See Fig. 2).
7. Turn wheel around and repeat procedure on the other
side of the wheel. This should be the long side of the drop
center. It will be easier to clamp the wheel to the table top if
the lower bead is loosened last. (See Fig. 3).
8. Determine the mounting side of the wheel. The mounting
side is the narrow side of the drop center. The tire is
removed for clarity. (See Fig. 4).
11
The unit must be properly operated and main-
tained to help avoid accidents that could damage
the unit and injure the operator or bystanders.
This section of the Operating Instructions manual
review basic operations and use of controls.
These instructions should be reviewed with all
employees before they are allowed to work with
the machine. Keep these instructions near the
machine for easy reference.
This machine may operate differently from
machines you have previously operated.
Practice with a regular steel wheel and tire
combination to familiarize yourself with the
machine’s operation and function.

9. Place tire/wheel assembly on table top with mounting
side up (See Fig. 1)
10. Use the clamp control pedal to move the clamps inward
(pedal down) or outward (pedal up). (See Fig. 2.)
11. Apply tire manufacturer’s approved rubber lubricant
liberally to entire circumference of both beads after loosening
bead and placing on table top. Using the mount/demount
roller to hold down the top bead while rotating the turntable
will make lubrication easier. (See Fig. 3)
12. Use the lower bead helpers to assist in the bottom bead
lubrication. (See Fig. 4)
13. After the wheel is secured to the turntable, pull the over-
head swing arm into position so that the mount/demount
head is directly over the edge of the rim. Push down on the
vertical slide until the mount/demount head comes in con-
tact with the edge of the rim. . ( See Fig. 5 )
14. Push the vertical slide down and position the demount
head into contact with the rim edge. (See Fig. 6-7)
15 .Push up on the locking handle to lock the slide into
position. As the slide is locked, the mount/demount head
will move upward approximately 1/8 inch and backward 1/8
inch from the rim edge. The mount/demount head roller
should not be in contact with the rim edge. (See Fig. 1)
12
NOTE
Clamp steel wheels from the inside (clamps
push outward against wheel). Clamp mag and
custom wheels from the outside (Clamps push
inward against the outside rim edge). Refer to
the Performance Tires and Wheels section.

16. Move the left hand top helper into position opposite the
mount/demount head positioning the edge of the helper just
outside the rim edge. (See Fig. 2-3)
17. Press down on the left hand control valve. (See Fig. 4)
18. Power the left top helper down to force the tire bead into
the drop the center of the wheel. (See Fig. 5-6)
19. Insert the smooth curved end of tool bar over the right
end knob of the mount/demount head and below the top
bead of the tire. (See Fig. 7 & 8)
20. Push the tool bar down toward the wheel to lift the tire
bead up and over the right -side knob portion of the demount
head. Hold the tool bar in this position.(See Fig. 9-10)
NOTE
This clearance will be maintained as long as the
slide lock remains locked. The operator may swing
the arm out of the way and back into place again
without needing to reposition the head when chang-
ing a like set of wheels. The tool clearance may
change with machine use and should be inspected
often. Failure to maintain proper clearance may
result in damage to the wheel rim or tire.

Note:
The Following Procedures show
optional equipment being used;
The Tire Changer you are using may not have the
Assist Tower Option.


CUSTOM AND SPECIAL WHEELS
If a custom wheel is damaged in dismounting, STOP, and
avoid damaging the other wheels. Continue only when the
cause is identified and corrected.
Alloy Wheels
Some manufacturers offer wheels with little or no drop
center. These are not DOT approved. The tire or wheel - or
both - can be damaged and the tire could explode under
pressure, resulting in serious injury or death. If you attempt
to mount/demount this type of wheel, use extreme caution.
European Performance Wheels (Asymmetrical Hump)
Some European wheels have very large humps except near
the valve hole. On these wheels, the beads should be
loosened at the valve hole on both the upper and lower
sides first.
Wheels with Low Pressure Warning Sensors
Performance wheels on some vehicles (including Corvette,
BMW, Lamborghini Diablo) have a pressure sensor
strapped to the rim opposite the valve hole. On these
wheels, the beads should be loosened at the valve hole on
both upper and lower sides first.
DEMOUNTING TUBE TYPE TIRES
1. After both tire beads are loosened, lubricate the beads
and rim liberally.
2. Position the demount head and bead lifting tool as
described earlier paying careful attention not to pinch the
tube. Depress the table top pedal and rotate only a short
distance at a time. This allows you to stop the process
should you suspect the tube is getting pinched.
3. After upper bead is demounted, remove tube and
demount lower bead.
MOUNTING
This information must be read and followed carefully to
prevent accidents and injuries during mounting.
FOR TUBE-TYPE TIRES
With tube-type tires, demount the upper bead
and remove the tube before de-mounting the
lower bead.
NOTE
Table top rotation can be stopped at any time by
removing your foot from the rotation pedal.
Normal table top rotation for demounting is
clockwise. Depress the table top pedal to rotate
this direction. To rotate the table top counter-
clockwise, lift the pedal up with your toe.
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
bystanders out of service area.
15
Never mount a damaged tire. Never mount a tire
on a rusty or damaged wheel. Damaged tires
and/or wheels may explode.

1. Inspect the wheel closely for damage. Clean the wheel
and remove any light corrosion or rubber residue. Do not
attempt to service heavily corroded wheels. ( See Fig. 1)
2. Inspect tire for damage, paying close attention to the
beads. Verify size match between tire and wheel.
( See Fig. 2)
3. Lubricate both tire beads liberally with tire manufacturer
approved lubricant. ( See Fig. 3)
4. Place tire over wheel and move tower and
mount/demount head into position as described earlier.
Position tire so that the lower bead is above the left
“duckbill” side of the mount/demount head and below the
right front knob. ( See Fig. 4)
5. Manually force the tire down into the drop center of the
wheel directly across from the mount head to reduce the
tensional force on the bead. Depress the table top pedal and
rotate the wheel to mount the lower bead. Rotate the table top
until the lower bead is fully mounted. ( See Fig. 5-6)
6. For the top bead, rotate the table top until the valve stem
is directly across from the mount head. Lift the upper bead
above the left “duckbill” side of the mount/demount head
and below the right front knob. ( See Fig. 7-8)

8. With the left side helper, press down on the tire near the
right side assist roller to hold the tire in the drop center.
( See Fig. 1)
9. Depress the table top pedal and rotate the tire until the
bead is mounted. The left side helper shoe will follow the tire
during rotation. ( See Fig. 2-5)
MOUNTING TUBE TYPE TIRES
1. Lubricate the beads and rim liberally.
2. Position the demount head and bead lifting tool as
described earlier. Mount the bottom bead first.
3. Round out the tube with a small amount of air. Avoid
pinching or forcing the tube. Apply rubber lubricant to the
tube.
4. Insert the tube into the tire paying careful attention not to
pinch the tube.
5. Depress the table top pedal and rotate only a short
distance at a time. This allows you to stop the process
should you suspect the tube is getting pinched.
6. Mount the top bead.
INFLATION INSTRUCTIONS
Tire inflation is performed in four steps: Restraint, Bead
Seal, Bead Seat, and Inflation. Read the explanation of
each step and understand them thoroughly before
proceeding.
Do not force the tire onto the rim. Bead damage
could result making the tire unsafe and/or
creating the risk of injury.
Fig. 1
Fig. 2
Fig. 3
Fig. 4
Fig. 5
Check inflation gauge for proper operation .
Accurate pressure readings are important to safe
tire inflation. Refer to the Operating Maintenance
section of this manual for instructions. If the rim
has been clamped from the outside for tire
mounting, release the clamps once bead seal is
obtained, lift the tire, and move the clamps to the
center of the table top.
Tire failure under pressure is hazardous. This tire
changer is not intended to be a safety device to
contain exploding tires, tubes, wheels, or bead
sealing equipment. Inspect tire and wheel carefully
for match, wear, or defects before mounting.
Always use approved tire bead lubricant during
mounting and inflation. The inflation pedal, located
at the center of the left side of the machine,
controls the flow of air through the inflation hose.
17

INFLATION PEDAL OPERATION
The three-position inflation pedal located at the center of the
left side of the machine serves three different functions. It
checks air pressure in the tire; controls the flow of air
through the inflation hose; and operates the “Jet-Blast” bead
sealing nozzles . ( See Fig. 1 )
Position One - Tire Pressure – With the inflation hose
attached to the tire valve and the pedal in this position, the
air gauge will register the air pressure in the tire. Whenever
your foot is removed from the pedal, it will return to this
position. ( See Fig. 2 )
Position Two - Tire Inflation – This is the first activated posi-
tion. With the inflation hose attached to the tire valve and the
pedal in this position, line pressure is allowed to flow through
the valve and into the tire for inflation. Tire pressure is not
indicated on the gauge in this position. ( See Fig. 3 )
Position Three - Bead Sealing – This is the second ( pressed
all the way down ) activated position. With the inflation hose
attached to the tire valve and the pedal in this position, line
pressure is allowed to flow through the valve and to the “Jet-
Blast” nozzles on the table top for bead sealing. ( See Fig. 4 )
TIRE INFLATION
The unit is equipped with a pressure limiter/regulator to
assist the operator with proper tire inflation. The pressure
limiter will keep most car and light truck tires from inflating
beyond 60 PSI (smaller tires may reach higher pressures).
It is the operators responsibility to follow all instructions and
to control inflation pressure as specified in these
instructions. (See Fig. 5)
18
Fig. 1
Fig. 2
Fig. 3
Fig. 4
Do not use the “Jet-Blast” bead sealing nozzles
without a tire and wheel positioned on the table
top. Dirt and debris could be blown into the air with
enough force to injure the operator or bystanders.
Do not use this position to inflate a tire.
Fig. 5
The clip-on air chuck on the end of the inflation
hose and all inflation related components should
be checked weekly for proper operation. DO NOT
USE this machine for tire inflation if any parts are
damaged or appear not in proper working order.

STAGES OF INFLATION
Review the following descriptions and diagrams carefully.
Refer to them as necessary during wheel restraint, bead
sealing, bead seating, and inflation to verify that you are
proceeding properly and safely.
STAGE ONE / WHEEL RESTRAINT
As an added safety precaution, a wheel restraint devise has
been added to protect operators during tire inflation.
1. Raise the left helper and support assembly and insert the
restraint devise as shown. (See Fig. 1)
2. Make sure the restraint tool is centered in the center hub
of the wheel then press down on the left hand control valve.
(See Fig. 2-3)
STAGE TWO / BEAD SEALING
1. Position valve stem in front of operator and connect the
inflation hose. (See Fig. 4)
2. Hold tire up against upper edge of the wheel. Be sure tires
top bead is over the bottom of the valve stem. (See Fig. 5)
3. Depress inflation pedal to position two and hold about one
second to begin air flow through tire valve, then depress pedal
to position three and hold briefly – less than 1 full second. The
blast of air from the jets will expand tire and seal the beads.
(See Fig. 6-7)
Check the function of the pressure limiter
regularly and maintain it according to the
instructions provided in this manual for safe and
proper operation. Do not tamper with or attempt
to adjust the pressure limiter. Tires requiring
inflation beyond 60 PSI should only be inflated in
a safety cage.
This devise is a restraint devise only. It will not
protect operators in the event of catastrophic
tire/wheel rupture or failure. Always use extreme
caution during the inflation procedure. As an added
safety precaution, safety cages that conform to
OSHA standard 1910.177 are recommended.
Hold the restraint tool firmly in place when
installing and/or removing from the left helper
assembly. The unit can drop suddenly to the floor.
Be sure to keep feet clear at all times.

4.
Release the inflation pedal and allow it to return to posi-
tion one. Verify that both beads are completely sealed to the
wheel. Repeat these steps if beads have not sealed. It may
be necessary to wait a few seconds for the air storage tank
to recover before attempting again. If tire and wheel are
properly lubricated and operator cannot achieve bead seal
after a few attempts, the valve core may be removed from
the valve stem to allow more air flow into the tire to assist
with bead seal. After bead seal is achieved, remove the
chuck and reinstall the valve core.
STAGE THREE / BEAD SEATING
Bead seating usually occurs on the long tapered side of the
wheel first and the shorter side last. Bead seating will
usually require at least 7 PSI in the tire. 40 PSI is the
maximum safe pressure at this stage regardless of tire
operating pressure. Most European import cars and many
aftermarket alloy wheels are very tight and can be difficult to
bead seat. Also note that asymmetrical hump and run-flat
tires are extremely difficult to bead seat. Follow tire
manufacturer's recommended procedure for bead seating.
1. Once tire pressure is indicated on the air gauge (inflation
pedal in position one; foot removed from pedal), continue to
inject air into the tire in short intervals. Check the pressure
frequently. Stand back during bead seat. Keep hands, arms,
and entire body away from tire during this procedure. Tire
beads should move outward and "pop" into their bead seat
position as pressure inside the tire increases. If this does not
happen, a problem exists. Investigate carefully. (See Fig. 1)
KEEP HANDS AND FINGERS CLEAR.
Keep entire body away from the tire
2. Release air pressure from the tire by pressing the manual
release valve button. NOTE: The inflation hose must be
attached to the valve stem during this procedure. (See Fig. 2)
20
Operator should keep hands, arms, and entire
body away from the tire during the remaining
bead seat and inflation procedures. Do not
stand over tire, as personal injury could result.
from inflating tire. Avoid distraction during
inflation. Check tire pressure frequently to avoid
over inflation. Excessive pressure can cause
tires to explode, causing serious injury or death
to operator or bystander.
Fig. 7
Fig. 1
Fig. 2
Check tire pressure frequently. Never exceed 40
PSI while seating beads. Once seated, never
exceed tire manufacturer's recommended air
pressure. Tires can explode, especially if they
are inflated beyond their limits. At all pressure
levels when inflating through the valve stem,
keep hands, arms, and entire body away from
inflating tire. An exploding tire, wheel, or bead
sealing equipment may propel upward and
outward with sufficient force to cause serious
injury or death to operator or bystander.
NEVER increase air pressure to exceed 40 PSI
when attempting Bead Seat. If operator is
unable to obtain Bead Seat, something is wrong.
Deflate tire completely, inspect tire and wheel,
correct any problems found, relubricate both tire
beads, and reattempt Bead Seal and Seat
procedures. Follow all safety instructions in this
manual and on machine.
MIS-MATCHED TIRES AND WHEELS
Never attempt to mount and inflate mis-matched
tires and wheels. Mis-matched tire and wheel
combinations can explode, causing personal
injury or death to operator and bystanders. For
safety, do not attempt to mount and inflate
mis-matched tires and wheels.
