Operators Protective Gear and 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.
WARNING
Failure to follow danger, warning, and caution instructions may lead to
serious personal injury or death to operator or bystander or damage to

CHAPTER BEAD LOOSENING, DEMOUNT AND MOUNT TIRE
OPERATING INSTRUCTIONS
The unit must be properly operated and properly maintained to help avoid
accidents that could damage the unit and injure the operato r o r b ysta
nders. This se ction of the Ope rating Instructions manual reviews the 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.
CAUTION – This machine may operate differently from machines you have pre
viously operated. Practice with a regular steel wheel and tire combination to
familiarize you with the machine’s operation and function. 4.1 BEAD LOOSENING,
and DEMOUNT TIRE 4.1.1 Deflate the air in the tire completely and pull out the
core. Use the special tool to detach any wheel weights on the rim (FIG17).
NOTE: Loosening the beads on a partially or fully inflated tire is unsafe and
causes excessive wear on pivots with friction against the bumper pads. Deflate
the tire completely to prolong the life of your machine.
FIG 16
FIG 17
FIG 18
4.1.2 Place the tire between the bead breaking blade and tire pressing runner
clog. (Fig18) Then step down the tire press pedal to detach the rim from the
tire(fig2-10 or 3-10). WARNING Watch your fingers and legs! Repeat the same
operation on the other parts of the tire to make the tire completely detached
from the rim. Place the wheel with the tire detached from the rim on the
turntable and step the clamp pedal(fig2-9; 3-9) to clamp the rim. Place the
wheel WITH DROP CENTER UP on the turntable, and clamp in position. Press the
wheel down while clamping. You can select the outer clamp and inner clamp to
clamp the wheel according to the rim type. To detach the lip smoothly,
you can use the brush to spread the lubricant or thick soap liquid between the
lip and rim.
WARNING – TO MINIMIZE THE RISK OF SCRATCHING ALLOY and PAINTED RIMS, THESE SHOULD BE CLAMPED FROM THE OUTSIDE.
WARNING! – ON CHEVROLET CORVETTE WHEELS WITH THE OPTIONAL LOW PRESSURE SENSOR INSTALLED, BREAK THE BEAD AT 90 DEGREES OFFSET FROM THE VALVE STEM. DAMAGE TO THE WHEEL WILL RESULT IF THE BEAD IS BROKEN AT ANY OTHER POINT ON THE RIM.
4.1.3 Position the hexangular shaft (FIG 2-3) to the working position to make
the demount tool close to the rim of the wheel. And use the hand wheel (FIG
7-2) to push against the rocker arm and then use the lock handle( FIG 2-12) to
lock. Position the mount/demount head in contact with the rim edge and lock it
into place: the tool automatically moves away from the rim edge vertically.
Turn the adjustment knob until the mount/demount head clears from the rim
flange about 2 mm (1/16″): this is necessary to avoid rim damage (FIG19).
The angle of the demount tool has been calibrated according to the standard
rim. Adjust as necessary for different size rims.
FIG 19
FIG 20
4.1.4 Use the bead lifting crowbar to detach until the lip to the hump of the
demount tool (FIG20). Press down the turntable rotation pedalFIG2-8to rotate
the turntable clockwise until the entire lip completely detached. Depress
the tabletop pedal to rotate the wheel clockwise. The demount head will guide
the upper bead up and over the edge of the wheel. 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. If desired, the bead lifting tool can be removed after lifting
the bead onto the finger.
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. 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. 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.
CAUTION
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 of
jam ups.
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.
In the process of demounting tire, you should keep your hands and the other
parts of your body as well as clothing from the movable parts to prevent
injury. 4.1.5 If handling the tube tire, to avoid the damage on the tube, you
should keep the valve stem of the tire 10cm from the right side of the demount
tool when demounting. When handling the tube tire, take out the tube and then
move the lower lip upwards to the upper edge of the rim and then repeat the
above steps to detach the other lip. 4.2 MOUNT TIRE 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. Attempts to force a bead
seat on mismatched 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.
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. WARNING – LIBERAL LUBRICATION OF THE TIRE AND RIM IS NECESSARY TO MOUNT
TIRE CENTERING CORRECTLY AND GET A PROPER ON THE RIM. BE SURE YOU ARE USING
APPROVED LUBRICANT ONLY. WARNING – OBSERVE THE ROTATION DIRECTION OF THE TIRE,
IF REQUIRED. SOME TIRES HAVE A COLOR DOT THAT MUST BE KEPT ON THE OUTSIDE OF
THE WHEEL. 4.2.1 Clean the dirt and rust on the rim and lock it on the chuck.
Lock the rim on the turntable. 4.2.2 Spread the lubrication liquid or soap
liquid around the tire beads. Tilt the tire against the rim and keep the front
end upwards. Press down the hexangular shaft to move the demount arm to
contact with the rim and lock. The left lip above the tail of the demount tool
and the right lip will be positioned under the front end of the demount tool
(FIG 21). 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.
FIG 21
For top bead, rotate the table top until the valve stem is at the 5 o’clock
position. Lift the upper bead up and over the rear of the mount head. 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.
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. 4.2.3If there is tube, place it in the tire and plug
the core. And assemble the lip according to the above mentioned
step (FIG22). In the process of clamping the rim, do not reach your hands in between the rim and the claw to avoid the damage to the personnel.
FIG 22
FIG 23
4.2 INFLATION
CAUTION, WARNING, DANGER
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. THE
RIM MUST BE UNCLAMPED WHEN INFLATING BUT ONLY AFTER BEADS HAVE BEEN SEATED.
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 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.
ATTENTION! WHEN OPERATING THE BEAD SEATER IT IS MANDATORY TO WEAR SAFETY
GLASSES TO PROTECT EYES.
The Inflation pedal operates in 3 positions as described below.
Position 1 (All the way up at rest) – 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.
Position 2 (Pushed down to the mid level) – 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. The pedal must be released to read pressure.
Position 3 (Pushed down all the way to lowest level) – 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 inflate 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 this
position to inflate a tire.
When the inflation pedal is held in position 2, the pressure should be checked
every few seconds to prevent over inflation. This cycling helps to prevent
over inflation of the tire. Tires can still be over inflated and explode with
the use of this technique and if all of the instructions in this manual are
not followed completely. It is the operator’s responsibility to follow all
instructions and to control inflation pressure as specified in these
instructions. Tires requiring inflation beyond 60 PSI should be inflated in a
safety cage.
Tire inflation is performed in three steps: Bead Seal, Bead Seat, and
Inflation.
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. 2. Depress inflation pedal to position 2 and
hold about 1 second to begin air flow through tire valve, then depress pedal
to position 3 and hold briefly less than 1 full second. The blast of air
from the jets will expand tire and seal the beads. 3. Release 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.
It may be necessary to wait a few seconds for the air storage tank to recover
before attempting again. Note: 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 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 tire and wheel, and 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.
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. THE RIM MUST BE UNCLAMPED
WHEN INFLATING BUT ONLY AFTER BEADS HAVE BEEN SEATED.
This machine is equipped with an inflation gauge for monitoring the inflation
of the tire and the inflation pressureFIG 22. 1. Connect the inflation hose
with the tire air core. See FIG23. 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. Release air pressure from tire by pressing the manual release valve
button (inflation hose must be attached to the valve stem).
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.
Requires rubber lubricant on both upper and lower beads
Table top jets
Air flow through valve requires about 140 PSI air pressure drop to insure
sufficient flow on difficult tires.
Lift tire up to assist seal on top side
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.
Usually last to “pop” is top side Do not stand over tire during inflation.
Requires visual confirmation of bead seat
Do not stand over tire during inflation.
DANGER!

Mismatched tire and wheel combinations explode, causing personal injury or
death to operator and bystanders.
For safety, do not attempt to mount and inflate mismatched tires and wheels.
Even Size Wheels 14.0, 15.0, 16.0,
17.0, etc.
Even Size Tires 14.0, 15.0, 16.0,
17.0, etc.
Note the gap in this area
Note 15° Bead Seat
Bead will not seat properly
Half Size Wheels 14.5, 15.5, 16.5,
17.5, etc.
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 wasn’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.
