OPERATING INSTRUCTIONS

The unit must be properly operated and properly
maintained 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.

BEAD LOOSENING AND DEMOUNTING

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.

Remember to remove all weights from both sides of
the wheel. Weights left on back side of wheel may
cause the wheel to be clamped unlevel. 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.

NOTE: Always review nicks and scratches with
owners of expensive wheel and tire combinations
prior to servicing.

IMPORTANT: 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 (Figure 1).

Figure 1 - Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a partially or
fully inflated tire is unsafe and causes excess
movement and friction against the bumper pads
and excessive wear on pivots. Deflate the tire
completely to prolong the life of your machine.

NOTE: Always loosen the bead on the narrow
side of the wheel's drop center first. See Figure
4 for more information on the drop center.

REMEMBER: The clamps on the table top may
extend beyond the table top itself. To avoid
damaging the clamps, move them to their full
inward position before positioning a tire for bead
loosening.

NOTE: Use extra care in positioning the bead
loosener 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.

2. Pull the bead loosener shoe away from the
machine and roll wheel into position. The valve
stem should be in the 3 o'clock position. Position
the bead loosener shoe against the tire next to,
but not on, the rim. Depress the bead loosener
foot pedal to actuate the shoe and loosen the
bead. It may be necessary to loosen the bead in
multiple locations around the tire (Figure 2).

Figure 2 - Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat loosening
procedure on the other side of the wheel. This
should be the long side of the drop center (see
Figure 4).

TIP: It will be easier to clamp the wheel to the
table top if the lower bead is loosened last.

4. Apply tire manufacturer's approved rubber
lubricant liberally to entire circumference of both
tire beads after loosening.

5. Determine the mounting side of the wheel. The
mounting side is the narrow side of the drop
center. (Tire removed in Figure 4 for clarity.)

Figure 4 - Determining Mounting Side of Wheel

6. Place tire/wheel assembly on table top with
mounting side up (Figure 5). Use the clamp
control pedal to move the clamps inward (push
pedal down) or outward (toggle pedal up).
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.

Figure 5 - Place Tire/Wheel Assembly on Table Top

7. Move the swing arm into position. Pull the
locking handle forward to release the slide.
Push down on the top of the vertical slide to
move the demount head into contact with the
rim edge. Push the locking handle back to lock
the slide into place. As the slide is locked, the
mount/demount head will move upward
approximately 1/8 inch from the rim edge.

Figure 6 - Position Mount/Demount Tool

8. The mount/demount head roller should be in
contact with the rim edge. Turn the swing arm
adjusting knob to move the roller away from the
rim 1/8 to 1/4 inch.

Figure 7 - Adjust Swing Arm to Position Head Roller

9. Check head positioning. Mount/demount head
should be positioned with 1/8 to 3/16" clearance
between the top of the rim edge and the bottom
of the head, and 1/8 to 1/4 inch clearance
between the rim edge and the head roller. This
clearance will be maintained as long as the
locking handle and adjustment knob are not
changed. The operator may swing the arm out
of the way and back into place again without
needing to reposition the head (when changing
the set of same wheels).

Figure 8 - Proper Mount/Demount Head Position

IMPORTANT: The vertical tool clearance may
change with machine use and should be
inspected often. Failure to maintain the proper
clearance may result in damage to the wheel
rim and/or tire.

10. Insert the smooth curved end of the bead lifting
tool over the forward end of the demount head
and below the top bead of the tire. Use your free
hand to press down on the tire opposite the
head to help with tool insertion (Figure 9).

11. Push the bead lifting tool down towards the
wheel to lift the tire bead up and over the knob
portion of the demount head. Hold the tool and
bead in this position (Figure 10).

Figure 10 - Lift Bead Over Demount Head

12. Depress the table top pedal to rotate the wheel
clockwise. The demount tool will guide the
upper bead up and over the edge of the wheel.

NOTE: Push down on the tire across from the
demount head during table top rotation to utilize
the drop center area of the wheel. This reduces
the tensional force on the bead during demount.

13. Lift and hold the tire at an angle so that the
lower bead is resting in the drop center directly
across from the demount head, and is loose
below the demount head (Figure 11). Insert the
smooth curved end of the bead lifting tool down
over the forward end of the mount/demount tool
and below the lower bead. Lift the bead up and
over the knob on the demount head (Figure 11).

Figure 11 - Demounting Lower Bead

14. Depress the table top pedal to rotate the wheel.
The demount tool will guide the bead up and
over the edge of the wheel. Continue rotation
until lower bead is demounted.

NOTE: With tube-type tires, demount the upper
bead and remove the tube before demounting the
lower bead.

NOTE: Table top rotation can be stopped at any
time by removing your foot from the pedal.

NOTE: Normal table top rotation for demounting is
clockwise. Depress the table top pedal to rotate this
direction. To rotate the table top counterclockwise,
lift the pedal up with your toe.

At times during the
mounting and

demounting proce­dure, the bead lifting tool may encounter resis­tance or come under load. Keep one hand firmly
on the tool to avoid possible tool disconnect.
Use the reversing feature to back out or jam ups.

After successfully completing the demount
process, proceed to Mounting (page 6).

Operator Protective Equipment

Always wear durable work clothing during tire
service activity. Shop aprons or shop coats may
also be worn, however, loose fitting clothing should
be avoided. Tight fitting leather gloves are
recommended to protect the operator's hands
when handling worn tires and wheels. Sturdy
leather work shoes with steel toes and oil resistant
soles should be used by tire service personnel to
help prevent injury in typical shop activities. Eye
protection is essential during tire service activity.
Safety glasses with side shields, goggles, or face
shields are acceptable. Back belts provide support
during lifting activities and are also helpful in
providing operator protection.

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. Mis-matched tires and wheels explode.

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 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).

Figure 14 - 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.

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.

INFLATION

Tire inflation is performed in three steps: Bead Seal,
Bead Seat, and Inflation. These steps are explained
in detail on page 13. Read the explanation of each
step and understand them thoroughly before
proceeding.

Check for proper infla­tion gauge 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 out-

side for tire mounting,
release the clamps, lift the tire, and move the
clamps to the center of the table top.

If the wheel/tire has a

diameter larger than

14 inches and is diffi­cult to bead seal, the clamps should be moved
to the center of the table top for the bead seal
operation.

Tire failure under pres-

sure 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 rear of the left side
of the machine, controls the flow of air through the
inflation hose.

NOTE: The clip-on chuck on the end of the hose
should always be an open style with all parts in
proper working order.

Position 1 - At Rest – 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.

Position 2 - Tire Inflation – This is the first
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
into the tire for inflation. Tire pressure is not
indicated on the gauge in this position.

Position 3 - Bead Sealing – This is the second and
last 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 air-flate bead seal jets on the table
top for bead sealing.

Use Position 3 for
bead sealing only. Do

not use this position
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 the position to inflate a tire.

IMPORTANT: The unit is equipped with a pressure
limiter to assist the operator with proper tire inflation.
When the inflation pedal is held in position 2, the
pressure limiter cycles the machine between
position 2 (inflation) and position 1 (at rest, no air
flow to tire). This cycling helps to prevent over
inflation of the tire. Tires can still be over inflated
and explode with the use of this pressure limiter if all
of the instructions in this manual are not followed
completely. 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
operator's responsibility to follow all instructions and
to control inflation pressure as specified in these
instructions. Check the function of the pressure
limiter regularly and maintain it according to the
instructions provided in this manual for safe and
proper operation. Tires that require inflation beyond
60 PSI should be inflated in a safety cage.

Bead Sealing

1. Connect the inflation hose to the tire valve stem.

Hold the tire up against the upper edge of the
wheel. Be sure the top bead of the tire is over
the bottom of the valve stem (Figure 15).

2. Depress the inflation pedal to position 2 and
hold about 1 second to begin air flow, then
depress pedal to position 3 and hold very briefly
– less than 1 full second. The blast of air from
the jets will expand the tire and seal the beads.

3. Remove your foot from the inflation pedal and
allow it to return to position 1. Verify that both
beads are completely sealed to the wheel.
Repeat these steps if beads have not sealed.

NOTE: If tire and wheel are properly lubricated and
the operator cannot achieve bead seal after 3 or 4
attempts, the valve core may be removed from the
valve stem to allow more air into the tire to assist
with bead seal. After bead seal is achieved, remove
the chuck and reinstall the valve core.

Bead Seating

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.

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 both the tire and wheel,
correct any problems found, relubricate both tire
beads, and reattempt Bead Seal and Bead Seat
procedures. Follow all safety instructions in this
manual and on machine.

1. Once tire pressure is indicated on the air gauge

(inflation pedal in position 1; 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.

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.

Inflation

NEVER exceed tire

manufacturer's

recommended air
pressure. Tires can explode, especially if inflated
beyond these limits. Keep hands, arms, and
entire body back 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.

1. Make sure both beads are seated. When both

beads are seated, the tire is ready for inflation.

2. Replace the valve core if it was removed.

3. Depress the inflation pedal to position 2 to

inflate the tire. The pressure limiter will cycle the
air flow as described earlier. On most passenger
car tires, the pressure limiter will cease air flow
at approximately 60 PSI. On smaller volume
tires, the limiter pressure may be higher.

NOTE: Release air pressure from the tire by
pressing the manual release valve button (inflation
hose must be attached to the valve stem).

PERFORMANCE, CUSTOM, AND
ALUMINUM WHEELS

Only tire technicians
with experience and

training on custom
wheels should attempt to service expensive
custom alloy or aluminum wheels and high­performance low-profile tires.

Pre-Operation Notes:

• Ensure all weights have been removed.

• Assistance will be required on wide wheels.

• Clamp wheel from the outside.

• Use ample lubricant for mount and demounting

• Always review wheel nicks and/or scratches

with the owner before servicing.

Aluminum and Custom Wheels

Follow instructions provided for standard steel
wheels, except:

A. After loosening and lubricating both beads,

rotate the table top until the clamps are in the
12, 3, 6, and 9 o'clock positions.

Figure 17 - Rotate Table Top to 12 O'clock

B. Clamp wheel from the outside. Position rim

edge into clamp at 12 o'clock position. Lower
the wheel and depress the clamp control pedal.
Slowly move the clamps inward until they
securely contact the outside edge of the rim.

TIP: This is usually accomplished by crouching
down in front of the tire changer, holding the
wheel with the right hand, and operating the
clamp control pedal with the left hand. This
allows the operator to watch the clamps as they
move to ensure proper, damage-free clamping.

Performance Tires and Wheels • Demounting

Follow these instructions for performance type tires
and wheels, including run-flat tires and their
associated wheels, and asymmetrical hump wheels.

1. Remove the valve core and completely deflate
the tire.

2. Pull the bead loosener shoe away from the
machine and roll the tire into position against the
bumper pads. Position the tire with the valve
stem in the 3 o'clock position (in direct line with
the bead loosener shoe). Always loosen the
bead on the narrow/mounting side of the wheel
first (Figures 4 and 18).

Figure 18 - Position Tire for Bead Loosening

NOTE: Wheels with an asymmetrical hump
have a larger "ledge" type hump around the
wheel except at the valve hole making them
more difficult to mount and demount (Figure 19).

NOTE: Some wheels have a low pressure
sensor/transmitter strapped to the wheel. This is
especially true on run-flat tire/wheel systems. The
sensor is positioned directly opposite from the valve
stem. To avoid damaging the sensor, always loosen
the top bead at the valve stem first, then loosen the
bottom bead at the valve stem, and then continue to
loosen the remaining circumference of the beads as
necessary (Figure 20).

Figure 20 - Wheel with Low Pressure Sensor/Transmitter

3. Loosen bottom bead, starting with valve stem
positioned directly next to the loosener shoe
(Figure 21).

Figure 21 - Loosen Bottom Bead

4. Liberally lubricate the bottom bead of the tire
(Figure 22).

Figure 22 - Lubricate Bottom Bead

5. Clamp the wheel to the table top as described in

item B on page 9. Always clamp custom wheels
from the outside.

6. Lubricate upper bead liberally. Use the bead

lifting tool to help push the tire bead down so the
bead area is easier to reach.

Figure 23 - Lubricate Upper Bead

7. Move swing arm into place and adjust as
described on page 4, steps 7, 8, and 9. Increase the
distance between the demount head and the wheel
an additional

1/16 to 1/8 inch with the adjustment
knob. Locate the valve stem directly under the
demount tool before proceeding.

Figure 24 - Position Valve Stem Under Demount Head

8. Insert bead lifting tool between knob on

demount tool and tire bead. Pull lifting tool down
over wheel to lift bead up and over the knob.

NOTE: On asymmetrical hump wheels and stiff
sidewall performance tires, it may be necessary
to use 2 optional drop center tools (part
#435685) to hold tire in the drop center so that
the bead can be lifted over the demount tool.

Figure 25 - Insert Bead Lifting Tool (Optional Drop Center
Tools Shown)

9. Hold lifting tool in place and depress the table

top control pedal momentarily to jog the wheel a
short distance.

• 5035 A/E Rim Clamp Tire Changer

Figure 26 - Pull Lifting Tool Down and Rotate Wheel

10. The lifting tool can usually be removed after
jogging the wheel a short distance. Continue to
jog the wheel to allow tire to flex where it
crosses the rim edge. Continue short rotations
until top bead is completely demounted.

Figure 27 - Remove Drop Center Tools

11. Demount lower bead. In most cases when
demounting performance tires, the lower bead
will be less difficult. Use help to lift, position, and
hold tire. Pay close attention to
sensor/transmitter location, and position it
directly below the demount tool when starting
the lower bead demount procedure.

Figure 28 - Use Help on Lower Bead, Watch Sensor

Performance Tires and Wheels - Mounting

1. Lubricate both tire beads liberally. Performance
tires will require more lubrication than standard
passenger car tires.

2. Mount the lower bead. In most cases, the lower
bead will mount easily.

Figure 29 - Mount Lower Bead, Use Lifting Tool

3. Position the valve stem directly across from the
mount/demount tool for top bead mounting. Lift
the top bead over the rear of the mount head.
Use the lifting tool to help push and keep the top
bead in the drop center during mounting, or use
an optional drop center tool to help hold the
bead in the drop center (Figure 29 & 30). Rotate
the wheel in short steps to mount lower bead.

NOTE: Mounting the top bead can be very
difficult when mounting new tires on many
performance and custom wheels.

Figure 30 - Mount Top Bead

4. Mount the top bead using short rotations of the
wheel. As the wheel progresses, a second drop
center tool should be added to keep the bead in
the drop center.

Figure 31 - Add Second Drop Center Tool

5. On extremely tight tire and wheel combinations,
it may be necessary to use the hooked end of
the bead lifting tool to flip the tire over the rim
flange (Figure 32).

6. After beads are mounted, unclamp wheel, lift it
slightly, and move the clamps to the center of
the table top. With the tire/wheel loose on the
table top, follow the detailed instructions
provided in the Inflation section of this manual
for bead sealing, bead seating, and inflation.

CUSTOM AND SPECIAL WHEELS

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 in
jury or death. If you attempt to mount/demount this
type of wheel, use extreme caution.

Figure 33 - No Drop Center

European Performance Wheels
(Asymmetrical Hump)

Some European wheels have very large humps
except near the valve hole. On these wheel, the
beads should be loosened at the valve hole on both
the upper and lower sides first.

Figure 34 - Asymmetrical Hump on European Wheels

Wheels with Low Pressure Warning System
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.

Figure 35 - Wheels with Low Pressure Sensor

TUBE TYPE TIRES

Mounting

1. Avoid pinching or forcing the tube.

2. Apply rubber lubricant to the beads of the tire.

3. Mount the bottom bead.

4. Put a small amount of air into the tube to round
it out.

5. Apply rubber lubricant to the tube.

6. Insert the tube into the tire.

7. Mount the top bead.

Demounting

1. After tire beads are loosened, lubricate the
beads and rim liberally.

2. Position the demount head and bead lifting tool
as described in steps 7 through 11 on pages 4
and 5. Depress the table top pedal and rotate
only a short distance at a time. This allows you
to stop the process should the tube get pinched.

3. After the upper bead is demounted, remove the
tube and demount the lower bead.

Do it Now

Make sure the instruction
and warning decal is
clean and clearly visible
to operator.

Bead Sealing

A 140 PSI air blast from the table jets creates an air
curtain to aid in bead sealing. Never exceed 10 PSI
in the tire during bead sealing. The tire will contain
about 2 PSI when bead seal is obtained.

STAGES OF INFLATION

Review these descriptions and diagrams carefully. Refer to them as necessary during bead sealing, bead
seating, and inflation to verify that you are proceeding properly and safely.

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 operating pressure.

Most European import cars and many aftermarket
alloy wheels are very tight and may be difficult to
bead seat. Also note that asymmetric hump and

run-flat tires are extremely difficult to bead seat.

Follow tire manufacturer's recommended procedure
for bead seating.

Inflation
After the beads are seated, the tire is inflated. Do
not inflate the tire above the manufacturer's

recommended pressure as stamped on the tire
sidewall. The typical inflation pressure for automobile
tires is between 24 and 45 PSI. Light truck inflation
pressure typically covers a wider range.

MIS-MATCHED TIRES AND WHEELS
Never attempt to mount and inflate mis-matched
tires and wheels.

Requires rubber lubricant on
both upper and lower beads.

Air flow through valve
requires about 140
PSI air pressure drop
to ensure sufficient
flow on difficult tires.

Lift tire up to assist
seal on top side.

Usually last to "pop" is top side

Requires visual conformation of bead seat

Do not stand
over tire during
bead seat and
inflation.

Table top jets

Do not stand over tire
during inflation.

Mis-matched tire and
wheel combinations

explode, causing
personal injury or death to operator and
bystanders. For safety, do not attempt to mount
and inflate mis-matched tires and wheels.

MAINTENANCE INSTRUCTIONS

Read and follow all the maintenance instructions
provided in this manual to keep the machine in good
operating condition. Refer to the other materials
received with the unit and to the service bulletins
from the manufacturer for additional instructions on
proper maintenance and service. Regular
inspections and proper maintenance are essential to
preventing accidents and injuries.

Before making any
inspection, adjust-

ment, or repair, dis­connect the power source and block out all mov­ing parts to prevent injury.

Keep the machine

and the immediate

work are clean. Do
not use compressed air to remove dirt and
debris from the machine. Foreign material may
