Operator Protective Equipment

Personal protective equipment helps make tire serv­icing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. 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.

Remember R.I.M.

Three Simple Steps To Help Keep Shops Safe

R.I.M. is a training program developed by Hennessy
Industries to help keep tire technicians safe. By follow­ing the basic principles of R.I.M., technicians can avoid
situations that can cause catastrophic accidents like
tire explosions.

R.I.M. stands for read, inspect, and mount:

Read the tire size on a new tire before mounting to

make sure it is the proper size for the wheel.

Inspect the wheel for cracks, rust, and or other dam­age that could cause an unsafe situation.

Mount the tire safely, making sure not to put any part
of your body over the tire during inflation.

The most serious of possible accidents is a tire explo­sion. This is often caused by a tire/rim mismatch.

If a tire explodes on a tire changer, pressure causes it
to fly straight up at tremendous speed. If a technician
is standing over the tire, he can be seriously injured or
killed.

Hennessy’s R.I.M. program allows the technician to
avoid situations that can cause tire explosions and
other accidents. The full program, including training
videos, brochures, posters, and other materials, is
available from Coats distributors nationwide.

For more details, contact your Coats distributor or e-mail us.

Operating Instructions

This 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 backside of
wheel may cause the wheel to be clamped
unleveled. This may result in the combination
Duckhead®contacting the rim causing
scratches. On alloy wheels, always rotate the
wheel one turn after setting the Duckhead to
insure proper wheel chucking.

B. Always review with the owner any nicks and
scratches on expensive wheel and tire combi­nations prior to servicing.

C. Review the performance wheel section of
this manual prior to servicing performance
tire/wheel combinations.

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.

1. Deflate the tire completely by removing the valve

core from the valve stem (figure 1). Be cautious and do
not smoke as a

flammable gas could have been intro-

duced into the tire at some time

.

Figure 1 - Remove Valve Core to Deflate Tire

Tires are always installed and removed from
the rim’s narrow side.

D. Always loosen the bead on the narrow side

of the wheel’s drop center first (tire removed in
figure 2 for clarity).

Figure 2 - Determine Narrow Side of Wheel

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. Actuate valve (or pull) to position the bead

loosener shoe away from the machine and roll wheel
into position. The valve stem should be in the 2 o’clock
position to accommodate a possible asymmetric
safety hump type rim. Position the bead loosener shoe
against the tire next to, but not on, the rim. Actuate the
bead loosener handle/button to position the shoe or
press the bead loosener pedal to position the shoe and
loosen the bead. It may be necessary to loosen the
bead in multiple locations around the tire (figure 3).

G. It will be easier to outside clamp the wheel
to the table top if the long side of the rim is
loosened last.

4. Apply tire manufacturer’s approved rubber lubri-

cant liberally to entire circumference of both tire beads
after loosening (figure 5).

Figure 5 - 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.
See figure 2 for more information on the drop center.

6. Place tire/wheel assembly on table top with

mounting side up (figure 6).

Figure 6 - Place Tire/Wheel Assembly on Table top

7. Use Robo Arm to apply pressure to aid in clamp-

ing rim (figure 7). 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.

8. 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 and 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 8).

9. The mount/demount head should be in contact

with the rim edge. Turn the swing arm adjusting knob
to move the mount/demount head away from the rim
1/8 to 1/4 inch (figure 9).

Figure 9 - Adjust Swing Arm to Position Head Roller

10. Check metal head positioning. Mount/demount

metal head should be positioned with 1/8 to 3/16 inch
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 10).

Figure 10 - Proper (Metal) Mount/Demount Head Position

11. Check plastic head positioning. Mount/demount

plastic head should be positioned with 1/16 to 1/8 inch
clearance between the top of the rim edge and the
bottom of the head, and 1/16 to 1/8 inch clearance

between the rim edge
and the inside surface of
the head. 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 11).

Figure 11 - Proper (Plastic) Mount/Demount Head Position

H. The 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.

J. 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.

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

At times during the mounting and
demounting procedure, the bead lifting tool
may encounter resistance and can be
thrown. Keep one hand firmly on the tool to
avoid possible tool disconnect. Use the
reversing feature to back out of jam-ups. A
thrown tool can cause injury.

12. Insert the smooth curved end of the bead lift-

ing tool over the forward end of the demount head and
below the top bead of the tire. Lift the bead up and
over the knob on the Duckhead (figure 12). Also, note
the valve stem position to the Duckhead. Use the Robo
Arm to push down on the tire opposite the Duckhead
to allow the bead to utilize the drop center area of the
rim, this position reduces stresses in the bead and
allows an easier bead lift.

Mounting

This information must be read and followed carefully
to prevent accidents and injuries during mounting.

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.

Check tire and wheel carefully before
mounting. Make sure the tire bead diame­ter and wheel diameter match exactly.
Consult the Tire Guide and/or Rubber
Manufacturer's Association for approved
rim widths for tire sizes.

Never mount a damaged tire. Never mount
a tire on a rusty or damaged wheel.
Damaged tires and/or wheels may explode.

When in doubt do not mount.

Never mount a tire and wheel handed to
you by anyone without checking both tire
and wheel for damage and to be certain the
sizes match. Do not let untrained persons
operate tire changer and keep bystanders
out of service area.

Forcing the tire onto the rim can cause bead
damage. If you damage the tire bead during
mounting, STOP!, remove tire and mark it
as damaged. Do not mount a damaged tire.

1. Before any mounting, inspect tire for damage and

verify size match between tire and wheel (fig. 16).

Figure 16 - Verify Size Match Between Tire and Wheel

2. Inspect wheel closely for damage. Clean the

wheel and remove any light corrosion or rubber residue
(figure 17). Do not attempt to service a heavily cor­roded wheel, damaged wheel, or bent wheel.

Figure 17 - Inspect and Clean the Wheel

3. Inspect valve stem and replace if necessary. Next

lubricate tire beads liberally with tire manufacturer’s
approved rubber lubricant (figure 18).

Inflation

Tire inflation is performed in three steps: BEAD
SEAL, BEAD SEAT, and INFLATION. These steps are
explained in detail on page 14. Read the explanation of
each step and understand them thoroughly before pro­ceeding.

Tire failure under pressure is hazardous. This
tire changer Will Not Restrain Exploding
Tires, rims or other related equipment.
Inspect tire and wheel carefully for match,
wear, damage, or defects before mounting.
Always use approved tire bead lubricant
during mounting and inflation.

The clip-on chuck allows the operator to
keep hands and entire body back from
inflating tire. The chuck must be an
open/freeflow style with all parts in proper
working order.

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.

The inflation pedal, located at the rear of the left side
of the machine, controls the flow of air through the
inflation hose, and has three positions.

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

Position 1 - 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 - 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 system and into the
tire for inflation. Correct 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 air­flate bead seal jets on the table top for bead sealing.

1. 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.

Use of bead sealing jets without a tire in
place can cause dirt and debris to be blown
into the air with enough force to injure
operator and/or bystander. Do not use the
bead sealing control position to inflate a
tire.

R. This 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 airflow 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. Do
not tamper with or attempt to adjust the pres­sure limiter. Tires requiring inflation beyond 60
PSI should be inflated in a safety cage.

Bead Sealing

1. Position valve stem in front of operator and con-

nect the inflation hose with the clip-on chuck. Hold tire
up against upper edge of the wheel. Be sure tire’s top
bead does not cover the bottom of the valve stem (fig­ure 24).

Figure 24 - Lift Tire Upwards for Bead Sealing

2. Depress inflation pedal to position 2 and hold

about one second to begin air flow through tire valve,
then depress pedal to position 3 and hold briefly —
less than one 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 pressure to recover before
attempting again.

S. If tire and wheel are properly lubricated and
operator cannot achieve bead seal after three
or four 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 clip-on
chuck and reinstall the valve core. Reattach the
clip-on chuck after core is installed.

CAUTION

12 • Important: Always read and follow the operating instructions.

Bead Seating

NEVER exceed 40 PSI to seat beads while
using this tire changer. If more than 40 PSI is
permitted by tire manufacturer, ALWAYS use
safety cage and clip-on chuck. NEVER
exceed recommended pressure after seat­ing beads. ALWAYS keep hands and entire
body back 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.

Check tire pressure frequently. 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.

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 (inflation pedal posi­tion 2) in short intervals. Check the pressure fre­quently. Stand back during bead seat. Keep hands,
arms, and entire body away from tire during this pro­cedure (figure 25).

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.

Figure 25 - Stand Back during Bead Seat

WARNING

DANGER

Important: Always read and follow the operating instructions. • 13

Inflation

NEVER exceed tire manufacturer's recom­mended air pressure. Tires can explode,
especially if inflated beyond these limits.
Use clip-on air chuck, 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 tires, the pressure limiter
will cease air flow at approximately 60 PSI. On smaller
volume tires the pressure may be higher.

4. Release air pressure from tire by pressing the

manual release valve button (inflation hose must be
attached to the valve stem, Figure 26). Never add or
adjust tire pressure using an air hose without a clip-on
air chuck and in-line valve. Do not use a hand-held style
chuck (figure 27).

5. Important: When inflating tires that require more

than 60 PSI, always use a safety cage and air hose with
a clip-on air chuck and in-line valve. The air hose must
have enough length between the chuck and the opera­tion/in-line valve to allow the operator to stand outside
the trajectory.

Note: If you change tires defined as truck tires, they

must be inflated per OSHA instructions.

Stages of Inflation on a

Conventional Tire and Rim

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

Bead sealing is the process of capturing air pressure between the
tire and the rim. The tire will usually contain about 1/2 to 2 PSI at ini­tial bead seal.

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 ready to be 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.

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

Usually last to “pop” is the mount side.

Requires visual
conformation of
bead seat.

Stand clear of the tire during bead seat and inflation.

Stand clear of the tire during inflation.

Requires rubber lubri­cant on both upper
and lower beads.

Important: Always read and follow the operating instructions. • 15

Mismatched Tires and Wheels

Never attempt to mount and inflate mis-matched tires
and wheels.

Mismatched tire and wheel combinations can explode,
causing personal injury or death to operator and/or
bystanders.

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 high-performance low­profile tires.

Pre-Operation Notes:

• Ensure all weights have been removed.

• Clamp wheel from the outside.

• Use ample lubricant for mount and demounting.

• Always review wheel nicks and/or scratches
with the owner before servicing.

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 2 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 2 and 28).

Figure 28 - Position Tire for Bead Loosening

AA. 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 29). Always loosen the beads near the
valve stem on both sides of rim.

Figure 29 - Asymmetrical Hump Wheel

AB. Some wheels/tires have a low pressure sen-

sor/transmitter strapped to the wheel (figure 30). This
is especially true on run-flat tire/wheel systems. The
sensor is positioned directly opposite from the valve
stem. Other low pressure warning systems have the
sensor as part of the valve. To avoid damaging the sen­sor, always loosen the top bead with the valve stem at
the 2 o’clock position first, then loosen the bottom
bead with the valve stem at the 2 o’clock position, and
then continue to loosen the remaining circumference
of the beads as necessary. Avoid loosening at 180 deg.
(opposite) the valve.

Aluminim and Custom Wheels

Follow instructions provided for standard steel

wheels, except:

AC. 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 32).

AD. 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.

4. Clamp wheel to the table top as described in item

AD. Always clamp custom wheels from the outside.

Figure 32 - Rotate Table Top to 12 o’clock

5. Depress the tire sidewall downward with the aid

of the robo foot providing clearance for the duckhead

®

to be positioned (figure 33). Move swing arm into
place. Increase the horizontal distance between the
demount head and the wheel an additional 1/16 to 1/8
inch with the adjustment knob.

Figure 33 - Helper Foot Depressing Sidewall of Tire

6. Lubricate upper bead liberally. Use the bead roller

tool to help push the tire bead down so bead area is
easier to reach for lubrication (figure 34).

Figure 34 - Lubricate Upper Bead

7. Locate the valve stem just before the demount

head before proceeding (figure 35).

Figure 35 - Position Valve Stem Under Demount Head

8. Insert the bead lifting tool between knob on

demount tool and tire bead (figure 36); use the helper
foot for extra clearance.

and over the knob and at the same time remove helper
foot (figure 37).

Figure 37 - Rotate Lifting Tool Down for Demount

10. Hold lifting tool in place, depress the table top

rotation pedal momentarily to jog the wheel a short dis­tance. Check the wheel and tire to verify that operation
is not causing damage. The lifting tool can usually be
removed after jogging the wheel a short distance.
Continue to jog the wheel to allow the tire sidewall to
flex as it crosses the rim edge. Continue short rotations
until top bead is completely demounted (figure 38).

Figure 38 - Rotate Lifting Tool Down for Demount

11. Demount lower bead. In most cases when

demounting performance tires, the lower bead will be
less difficult. Pay close attention to sensor/transmitter
location, and position it just before the demount tool
when starting the lower bead demount procedure (fig­ure 39).

Figure 39 - Rotate Lifting Tool Down for Demount

12. Use the upper side of the helper foot to hold the

bead in drop center while lifting the lower bead over
the demount tool (figure 40). Hold the lifting tool in
place and remove the helper foot. Depress the table
top rotation pedal momentarily to jog the wheel short
distances to complete the demounting process.

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.

AE. Mounting the top bead can be very difficult when

mounting new tires on performance and custom
wheels. Proceed slowly and cautiously.

3. For top bead installation, rotate table top until the

valve stem on wheel is 180 degrees ahead of the
Duckhead (9 o’clock position). Attach Duckhead roller
to the Duckhead using robo arm to assist (figure 41).

Custom and Special

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.

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 43).

Figure 43 - No Drop Center

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 44).

Figure 44 - 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 45).

Figure 45 - 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. 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.

Pressure Limiter Maintenance

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.

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.

The pressure limiter helps prevent inflation of stan­dard size or 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 certified tank with at least 250 PSI pressure rating.

3. Depress inflation pedal to position 1 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 airflow
automatically. Both gauges should read 60 PSI ± 5 PSI.

5. Release inflation pedal. 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.

Oil Injector Maintenance (If equipped)

The oil injector (on units so equipped) typically require
annual service. The oil level in the oil reservoir tank
should be checked regularly.

Add oil to oil reservoir tank when fluid level is a quar­ter full or below. Remove cap from the oil reservoir
tank and add Texaco Rando®HD 22 oil to full line (SAE
low non-detergent or air tool oil are acceptable substi­tutes). Replace cap and clean up any spilled oil.

Important: An air lock will form if the hose between
the reservoir and injector is ever empty of oil. In this
case, after filling the reservoir tank, the line must be
bled of air at the injector connection as follows:

1. Disconnect all power sources, both air and elec-

tricity inputs. Allow any stored air in the reservoir to
escape by depressing the inflate pedal.

2. Remove the side panel and locate the oil injector.

3. Prime the oil injector.

a. Oil Injector With Bleeder Screw

Loosen bleeder screw until oil drips from screw
and all air is relieved from the oil line hose.
Retighten the bleeder screw.

b. Oil Injector Without Bleeder Screw

Remove the oil line hose from the injector barb fit­ting. Allow air to escape from the hose by lowering
the hose end below level of reservoir until oil is
present. Drip oil into hose barb fitting on injector
until barb fitting is full. Reinstall oil line hose onto
oil injector barb fitting.

4. Reconnect air/electric sources and cycle the

clamp control pedal a few times checking for oil and air
leaks.

5. Test the machine for full function before returning

the machine to operation.

6. Monitor oil consumption to ensure oil is being

used in system.

DANGER

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.
