WARNING
Operator Protective Equipment
Personal protective equipment helps make tire
changing safer. However, equipment does not take
the place of safe operating practices. 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 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. Consideration should also be given to
the use of hearing protection if tire service activity
is performed in an enclosed area, or if noise levels
are high.

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.
A. 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.
B. Always review nicks and scratches with owners of
expensive wheel and tire combinations prior to
servicing.
C. 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.
D. 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.
E. 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.
F. 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. Press the button on
the bead loosener 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).
G. 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 (Figure 3).
Figure 3 – Apply Rubber Lubricant to Tire Beads

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 inwards (push
pedal down) or outwards (toggle pedal up).
Clamp steel wheels from the inside (clamps
push outwards against wheel). Clamp mag and
custom wheels from the outside (clamps push
inwards 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 rim edge (Figure 6).
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).
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
a like set of wheels) (Figure 8).
Figure 8 - Proper Mount/Demount Head Position
Figure 8A – Depicts proper mount/demount
head positioning with the standard 6065 head.
Figure 8B – For additional protection on
decorative wheels, the nylon "bootie" (part
#182963) should be used. The clearance may
also be reduced when using the "bootie."
Figure 8C – For maximum protection on
decorative wheels, the optional nylon head
should be used (part #182960). This head
replaces the metal head. The vertical locking
mechanism "lift" feature must also be reduced to
1
⁄
16".
H. 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.

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).
Figure 9 - Insert Bead Lifting Tool
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 (Figure 10). The
bead lifting tool may now be removed from
between the tire and the wheel.
Figure 10 - Lift Bead Over Demount Head
12. Depress the table top pedal to rotate the wheel
clockwise. The demount head will guide the
upper bead up and over the edge of the wheel.
J. 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 top or first bead
during demount (Figure 9).
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 12).
Figure 11 - Demounting Lower Bead
14. Depress the table top pedal to rotate the wheel.
The demount head will guide the bead up and
over the edge of the wheel. Continue rotation
until lower bead is demounted.
Figure 12 - Guide Lower Bead Over Tool Head
K. With tube-type tires, demount the upper bead and
remove the tube before demounting the lower bead.
L. Table top rotation can be stopped at any time by
removing your foot from the rotation pedal.
M. 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.
The bead lifting tool may
encounter resistance or
come under load at times
during the mount and demount procedures.
Keep one hand firmly on the tool to avoid
possible tool disconnect. Use the reversing
feature to back out of jam ups.
After successfully completing the
demount process, proceed to Mounting
(page 6).

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 tire bead
diameter and wheel diameter match exactly.
Consult the Rubber Manufacturers Association's
charts or The Tire Guide for approved rim widths
for tire sizes (contact information included with
Table of Contents).
Attempts to force a bead
seat on mis-matched tires
and wheels can cause the
tire to explode violently, 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.
Never mount a damaged
tire. Never mount a tire on
a rusty or damaged wheel.
Damaged tires and/or wheels may explode
during bead seat and or inflation.
If you damage 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 13). Do not attempt to service
heavily corroded wheels.
Figure 13 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying close attention
to the beads. Verify size match between tire and
wheel (Figure 13).
3. Lubricate tire beads liberally with tire
manufacturer approved lubricant (Figure 14).
Figure 14 - Lubricate Beads
4. Place tire over wheel and move swing 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 15).
Figure 15 - 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 16 - 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 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
table top pedal and rotate tire until the bead is
mounted. Continue to press down on tire during
the remaining mounting process (Figure 16).
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 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 32, page 11.
R. For tube type tires, mount the lower bead first,
move swing arm out, install the tube, and then
mount the upper bead.

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 outside
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
pressure is hazardous.
This tire changer is not
intended to be a safety device to contain
exploding tires, tubes, wheels, or supplemental
bead sealing equipment that may be attached to
the tire/wheel assembly. 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
bead sealing jets and the inflation
hose to achieve bead seal.
The bead seating/inflation hand
control valves are located on the
back side of the
Inflation Guard.
These valves control
air pressure flow
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. On open style
chuck is on that allows air flow when not
attached to a valve, and will flow air when the
foot valve or hand valves are actuated.
Use the bead seal pedal
for bead sealing only. Do
not use this control to
bead seat or inflate the tire. Inflating the tire with
this feature bypasses the pressure liminting
features and could lead to over inflation and
possible tire explosion. Do not use this pedal
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.
S. The unit is equipped with a pressure limiter to
assist the operator with proper tire inflation. When
the inflation valves are pushed open simultaneously
and held, the pressure limiter cycles the air flow on
and off, checking the tire pressure during the off
cycle. 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. Do not tamper with or attempt to
adjust the pressure limiter. Tires requiring inflation
beyond 60 PSI should be inflated in an inflation
chamber/safety cage, or securely mounted on the
vehicle if such a device is not available.
Bead Sealing
1. Position valve stem in front of operator and
connect the inflation hose. Hold tire up against
upper edge of the wheel. Be sure tire’s top bead
is over the bottom of the valve stem (Figure 17).
Figure 17 - Lift Tire Upwards for Bead Sealing
2. Depress the bead seal pedal and hold for about
2 seconds. The blast of air from the jets will
expand the tire and seal the beads to the rim.
3. Release the bead seal pedal. 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.

CAUTION
Page 10
T. If tire and wheel are properly lubricated and
operator cannot achieve bead seal after 3 or 4
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.
Bead Seating
Operator should always stand
behind Inflation Guard and keep
hands, arms, and entire body
away from the tire during the remaining bead seat and
inflation procedures. Do not permit anyone to stand over the
tire as personal injury could result.
Operating a tire changer with a
defective, improperly adjusted,
or by-passed pressure limiter
could cause an operator to accidentally over-pressurize a
tire, resulting in a tire explosion with severe injury or death
to the operator or bystanders. Always be sure that the
pressure limiter is present and is operating properly on the
machine at all times.
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 the tire and wheel for defects and make
sure that the tire and wheel size match. Correct any
problems found, relubricate both tire beads, and reattempt
bead seal and seating procedures.
1. Once the tire is sealed to the rim, move to the
area behind the Inflation Guard and push the
inflation valves simultaneously. Both valves
must be actuated to inject air into the tire.
Continue to inject air into the tire in short
intervals, checking the pressure frequently.
Stand behind Inflation Gaurd 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 for defects
and make sure the tire and wheel sizes match.
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, stay behind the Inflation Guard and 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. Stay behind
Inflation Guard and 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 inflation valves simultaneously and
hold to inflate tire. 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 pressure may be higher.
U. Release air pressure from tire by pressing the
manual release valve button (inflation hose must be
attached to the valve stem, Figure 18).

Performance, Custom, and Aluminium
Wheels
Only tire technicians with
experience and training
on custom wheels should
attempt to service expensive custom alloy or
aluminum wheels and high-performance lowprofile 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:
AA. 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 19 - Rotate Table Top to 12 O'clock
AB. The normal position for all clamps is position 1
(or the most inward position). This provides
outside clamping of wheels 10 to 17.5 inches in
diameter, and inside clamping of wheels from 12
to 20 inches in diameter
Use position 2 only on large diameter wheels.
This provides outside clamping of wheels 14 to
21 inches, and inside clamping of wheels from
16 to 24 inches in diameter.
Figure 20 - Adjustable Clamp Positions
AC.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 valve core and completely deflate 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). Reposition the bead
loosener positioning pin for wheels over 10
inches wide. Always loosen the bead on the
narrow/mounting side of the wheel first (Figures
4 and 21).

AD: 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 22).
Figure 22 - Asymmetrical Hump Wheel
AE: 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 23).

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 32 - Mount Upper 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 (Figures 32 and 33).
Rotate the wheel in short steps and apply extra
lubricant to mount upper bead.
AG: Mounting the top bead can be very difficult
when mounting new tires on performance and
custom wheels. Proceed slowly and cautiously.

4. Mount the top bead using short rotations of the
wheel. On stiff sidewall tires, add a second drop
center tool to keep the bead in the drop center.
Figure 34- 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 35).
Figure 35 - Use Hooked End of Bead Lifting Tool
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
If a custom wheel is
damaged in mounting or
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 (Figure 36).
Figure 36 - No Drop

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 (Figure 37).
Figure 37 - Asymmetrical Hump on European Wheels
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 (Figure 38).

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. Round out the tube with a small amount of air.
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 demount head and bead lifting tool as
described in steps 7 through 11 on pages 4 and
5. Depress 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 upper bead is demounted, remove tube
and demount lower bead.

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 Sealing
A 140 PSI air blast from the table top 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 1/2 to 2 PSI when bead seal is
obtained.
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.
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.
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.

Separator/Lubricator Maintenance
Check oil and water levels regularly, and perform
these maintenance items weekly:
A. Disconnect air supply to machine.
B. Drain water from the separator by unscrewing
the petcock on the bottom of bowl. Allow water
to drain and tighten petcock securely by hand.
C. Add oil to the lubricator if the fluid level is more
than 1/4” from the top of the gauge. Remove the
filler plug on top of the lubricator and add SAE
10W non-detergent oil or an air tool oil to bring
the level up to 1/4” from the top of the gauge.
Replace filler plug and clean up any spilled oil.
D. Adjust the oil flow by pulling the red flow
adjustment ring up and turning it to increase or
decrease the flow. Push the ring down to lock.
Watch the formation of oil drops in the seethrough oil chamber. Reconnect the air supply
and continually cycle the bead loosener through
full strokes and count the drips during the
cycles. The delivery of oil to the air line should
be about 1 drop per 10 cylinder cycles. Adjust
flow as required.
Mount/Demount Head Cleaning
Clean dirt and debris from the mount/demount tool
(duckhead) roller with small screw driver or pick.
Pressure Limiter Maintenance
The pressure limiter helps prevent inflation of
standard size of larger tires or tubes beyond 60 PSI
to minimize risk of explosion. This device is for the
safety of the operator and bystanders. Proper
operation of the pressure limiter is essential to safe
operation of the machine.
Check operation of the pressure limiter as shown
and described below at least monthly:
1. Remove tires and/or wheels from the machine.
2. Connect the inflation hose to an empty service
tank with a pressure gauge (gauge should read
0). Use a tank with a 250 PSI pressure rating.
3. Actuate inflation valves to start air flow through
the hose and into the tank. Maintain a steady
pressure for constant flow.
4. Watch the rising pressure on the tank gauge
and the gauge on the machine. Machine gauge
should cycle between check and inflation
pressures while tank gauge climbs steadily. As
tank pressure reaches 60 PSI, the pressure
limiter should stop the air flow automatically.
Both gauges should read 60 PSI ± 5 PSI.
5. Release inflation valves. Check manual release
valve function by pressing the button and
releasing pressure from the tank until it reaches
50 PSI. Disconnect inflation hose, and release
air inside tank.
6. Replace pressure limiter if it fails to cycle
properly during inflation, if it fails to shut air
supply off at 60 PSI, or if it malfunctions in any
other way. Do not operate machine with a faulty
pressure limiter.
Operating a tire changer
with a defective,
improperly adjusted, or
by-passed pressure limiter could cause an
operator to accidentally over-pressurize a tire,
resulting in a tire explosion with severe injury or
death to the operator or bystanders. Always be
sure that the pressure limiter is present and is
operating properly on the machine at all times.
Never inflate tire above
manufacturer’s
recommended pressure
after bead is seated. Pressure limiter is set at 60
PSI. Any required inflation above 60 PSI should
be performed in an inflation chamber/safety
cage or securely mounted on the vehicle if an
inflation chamber is not available. A tire
explosion may cause personal injury or death to
operator or bystanders may occur.

READ…
Mounting and inflating the
wrong size tire can get
you hurt. Read the size on
the tire and make sure it
matches the rim. Be especially careful about putting
a smaller tire on a larger
rim, such as a 16-inch tire
on a 16.5-inch rim.
Inflation of a mismatched
tire and rim can cause an
explosion.
INSPECT…
Before you put any tire on
a rim, inspect the rim for
rust, tough spots, bent
edges, or cracks that
could prevent the tire from
seating right. If you spot
any of these problems,
don’t mount the tire until
the rim has been checked
by your shop foreman.
Inspect the tire for bead
damage.
MOUNT…
Once you’ve made sure the tire is OK
and the right size and the rim is OK,
mount the tire safely. NEVER, ever
lean over the tire when you’re inflating
it. If a tire does explode, it will go
straight up. You don’t want to be over
the tire if that happens. Also, never
over-inflate the tire, even if the bead
doesn’t seat. Never inflate over 40
PSI. If the tire hasn’t seated, something is wrong. Deflate the tire and
check it and the rim again. If it doesn’t
work the second time, try another tire.
