Remember R.I.M.
Three Simple Steps To Help Keep Shops Safe
READ INSPECT MOUNT
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, are available from
Coats distributors nationwide.

by means of the adjustment knob, start turning manually the conical terminal thus acting on the expanding nut.
Then, release the button and keep on turning the conical terminal until the button pops up again.
12 • Important: Always read and follow operating instructions.
Positioning the Valve
Fig. 6 shows a rim in the form of a clock. In the following
Mounting and Demounting process steps, you will position
the rim with clock directions, so that the valve and pressure
sensor do not get damaged.
CAUTION
To avoid damaging the valve and pressure sensor,
(if installed) you must always arrange the valve in
the position indicated, following the instructions
when mounting and demounting the tire. fig.6
Tire Classifi cation
LOW PROFILE tires (UHP) are those in which the height (H) and the width (C) have a ratio lower than 0.5 (i.e.
low profile series 45 stands for a ratio of H/C = 0.45).
For tires to be considered as LOW PROFILE (UHP), they must also have a maximum speed code of equal to
or higher than V.
RUN-FLAT tires are those which, even when they have no internal pressure, allow you to continue to drive the
vehicle for a preset number of miles and at a preset speed. These parameters change from one manufacturer to
another. The market currently offers 2 different types of RUN-FLAT tires:
• Those with REINFORCED SIDE (SELF-SUPPORTING) where, thanks to a different mix and a reinforced
structure, the shoulder of the tire is able to bear the weight of the vehicle even when the pressure in the tire
is zero.
• Those with INTERNAL SUPPORT have a ring inside the rim that bears the side of the tire when there is no
pressure inside it. The internal support may be made of plastic or metal.
The tire changer is able to handle all types of LOW PROFILE (UHP) and all types of RUN-FLAT tires with
REINFORCED SIDE; for other types, refer to the specific instructions of the dedicated accessories, if available.
The mounting and demounting procedure is the same, be it a RUN-FLAT tire with REINFORCED SIDE (SELFSUP-PORTING) or a LOW PROFILE tire (UHP).
CAUTION
It is crucial to follow the instructions very carefully in order to avoid irreparable damages to the tire,
which could compromise the vehicle’s safety.
Important: Always read and follow operating instructions. • 13
Tire Pressure Monitoring System (TPMS)
TPMS, Tire Pressure Monitoring System is an electronic system designed to monitor the air pressure inside the
tires through special sensors mounted inside the wheels, which provide real-time tire-pressure information and
inside temperature data to the vehicle’s electronic control unit. Tire pressure system alerts the driver when the
tire pressure falls 20% below the recommended pressure, thus increasing your safety on the road.
This chapter describes the correct positioning of TPMS valve during the different working stages, in order to
avoid any damage.
Bead Loosening:
Place TPMS valve at “2:00 o’clock” position.
Start pushing on the tire bead using the upper
bead loosening disk.
Demounting tool positioning:
Place TPMS valve at “2:00 o’clock” position. Bring the
demounting tool into working position. While spinning the
wheel, insert the demounting tool into the drop center
level. Stop tire rotation when the valve reaches 11 o’clock
position.
Upper Bead demounting:
Spin the clamping chuck (clockwise) by pressing pedal 1
until the valve reaches “1 o’clock” position (at about 10 cm
from the demounting tool) so as to avoid possible damages
to the TPMS valve.
Warning: Rim and Tire must spin together as one,
during bead demounting operations, to avoid displacement
of TPMS sensor.
Lower Bead demounting, with demounting tool:
Place TPMS valve below the demounting tool at
“12:00 o’clock” position.
Lower Bead demounting, with bead loosening disk:
Place TPMS valve towards the bead loosening disk.
Lower Bead mounting:
Place TPMS valve at “5:00 o’clock” position, in any case
at about 10 cm from traction point.
Upper Bead mounting:
Place TPMS valve at “5:00 o’clock” position, in any case
at about 10 cm from traction point.
14 • Important: Always read and follow operating instructions.
Bead Loosening
Ensure the tire is completely deflated before starting any operation on the wheel.
Before lifting and positioning the wheel onto the clamping chuck, use the proper tool to remove any weights
from the rim, paying attention to not damage the rim.
Before starting any operation, check for the presence of a pressure sensor. If equipped, check its operation with
a dedicated diagnostic tool.
It is possible to unlock the disk support and enable a spring loaded movement, changing the angle of the disk,
increasing its penetration inside the rim. Particularly effective with soft tires.
Upper Bead Loosening
Check the correct centering and locking of the wheel onto the clamping chuck.
Check that the upper disk arm is in the working position.
Turn switch 6 to unlock the bead loosener and position it by pressing buttons 8, 9, 10 and 11 on the
console, so that the distance between the upper disk and the rim edge is 5 mm (fig. 1), then lock the bead
loosener by turning switch 6 again.
Pay special attention to the valve sensor position, if any, during bead breaking operations.
Wrong movements of the bead loosening disks could damage the sensor.
Spin the clamping chuck until the valve is in the
3 o’clock” position.
Lower the bead loosener disk until it touches the tire using
controls 10 for lifting and 11 for lowering.
Start spinning clockwise.
Note: the clamping chuck can spin at 2 different speeds, according to operator’s preferences.
While spinning the wheel, push the upper bead loosener
disk down below the edge of the rim, then press and hold
down the “over-run” function button 5 while gradually lowering the bead loosener disk until the bead is removed from
the rim.
As soon as enough space is available, a proper tire lubricating paste should be carefully applied to both the inner
surface of the rim and the tire bead (fig. 2).
Avoid contacting pressure sensor with lube paste if installed.
Once the bead is loosened, using button 10 to raise the upper bead loosening disk and move away.
Important: Always read and follow operating instructions. • 15
Lower Bead Loosening
Keep the bead loosener system set up as for upper bead
loosener disk procedure: the lower bead loosener disk is
always aligned with the upper one, and it is already positioned
at 3-4 mm from lower rim edge.
Lift the lower bead loosener disk until it touches the lower tire
bead using controls 13 for lifting and 12 for lowering.
Rotate wheel clockwise.
While spinning the wheel, push the lower bead loosener disk
up above the edge of the rim, then press and hold down the
“over-run”function button 5 while gradually lifting the bead
loosener disk until the bead is removed from the rim.
As soon as enough space is available, carefully apply tire lube paste to both to the rim inner surface and to the
tire bead (fig. 2).
NOTE: For a better view and control of the lower bead loosening, use the mirror mounted on the main frame.
fi g. 2
While lossening the bead, just press on the bead and never on the side of the tire.
Match Mounting
Driving could be affected by vibrations caused by
deformations of the rim and/or tire. To optimize the
wheel-balancing, it is necessary to position the wheel
onto the Tire Changer again to bead loosen and lubricate
the rim and the tire, spinning the tire around the rim to a
proper position.
Both upper and lower disks make this process easier,
by gently holding the tire steady while the clamping
chuck spins the rim until the correct matching position is
reached.
16 • Important: Always read and follow operating instructions.
Tire Demounting
Once the bead loosening process is completed, and the wheel is already positioned on the clamping chuck,
check and ensure its locked and centered.
Upper Bead Demounting
Bring the tilting tower close to the wheel by pressing pedal 1, while simultaneously placing the mounting tool
over the rim edge using the handle (fig. 1). Set the locking button 19 to position 1 (fig. 2) to lower the
operating arm, then lock everything by setting the locking button in position 2. In this way the mounting tool will
automatically move to the right distance from the rim, at about 2 mm.
Rotate the clamping chuck by pressing pedal 2 until the valve is in the “1 o’clock” position (roughly 10 cm dis-
tance from the mounting tool) in order to avoid possible damages to the valve or pressure sensor - if equipped.
Lower the lever 20 to insert the mounting tool between the bead and the rim edge. The mounting tool should
penetrate enough to hook the tire bead to let the operator complete the tire demounting.
Slowly spin the clamping chuck until the mounting tool is positioned correctly. This will facilitate mounting tool
penetration and tire hooking.
By gently pushing the lower bead loosener disk against the tire lower sidewall and the pneumatic bead pressing
arm against the upper sidewall at the “6 o’clock” position, it will be easier to fit the tool into position (fig. 4).
As soon as the bead is perfectly hooked, lift the mounting tool using the
lever 20 to pull out the bead.
To make the lifting easier, set the bead pressing arm at “6 o’clock”
position and press the sidewall (fig. 4) using pneumatic bead pressing
arm.
Press down pedal 2 to rotate the wheel clockwise until the upper bead is
completely off the wheel rim.
NOTE: Rim and Tire must spin together as one. To help the upper bead off
the Rim and reduce the stress to the Tire, insert the plastic lever
(fig. 5) and spin the wheel clockwise while lifting the tire with the lower
bead loosener disk.
Important: Always read and follow operating instructions. • 17
Lower Bead Demounting
Press pedal 1 to move the mounting arm away from the
working position.
Before pulling out the lower bead, spin the clamping chuck
to let the valve reach “1” or “2” o’clock position in order to
avoid possible damages to the valve and the pressor sensor
- if equipped.
Raise the lower bead loosening disk to lift the tire until the
lower bead is 1 cm over the upper rim edge (fig. 1).
Spin the wheel clockwise until the tire is completly off Rim.
Check the pressure sensor - if equipped - and replace if
necessary.
NOTE: Rim and Tire must spin together as one.
To help the lower bead off the Rim and reduce the stress to the Tire,
insert the plastic lever and spin the wheel clockwise while lifting the
tire by the lower bead loosener disk.
Tire Mounting
Check the rim and the tire carefully, as per instructions on pg. 4.
If the rim has been removed, lock it again onto the centrer plate
per instructions on pg. 12.
Carefully lubricate the whole inner surface of the Rim and the
beads of the Tire, both externally and internally around the
circumference, for a width of at least 3 cm.
Avoid contacting pressure sensor with lube paste if equipped.
Lower Bead Mounting
Put the Tire on the Rim with it tilted at “12 o’clock” position in
order to make both upper and lower beads go under the upper rim
edge.
Press pedal 1 to approach the mounting arm and position the
mounting / demounting tool on the Rim edge.
Incline the tire down at the “3 o’clock” position, driving the lower
bead on the mounting tool in order to put the lower bead over its
left side and under it on its right side.
Rotate the wheel clockwise by pressing the pedal 2, while
pressing the tire manually at “5 o’clock” position until the lower
bead reaches the drop center level. Keep the tire pressed while
rotating up to “8 o’clock” position to complete the lower bead
mounting.
18 • Important: Always read and follow operating instructions.
Upper Bead Mounting
Keep the mounting arm and the mounting tool in working position and proceed with mounting of the upper
bead, then put the tire bead on the rim slightly tilted down to “3 o’clock” position, so that the upper bead rests
on the left side and under the right side of the mounting tool (fig. 1).
Bead correctly positioned over the left side of the
mounting tool and under it on its right side.
Press the pedal 2 to rotate the wheel clockwise, contemporarily press the tire manually from “5 o’clock”
position to force the upper bead at drop-centre position. Keep it pressed while rotating up to “8 o’clock” position
to complete the upper bead mounting (fig. 2).
It is advisable to use the pneumatic bead pressing arm (fig.2) for standard tires that are particularly difficult to
bead loosen. (fig. 3).
Press the buttons (fig. 4) to use using the bead pressing tool to push on the tire bead at “5 o’clock” position,
press pedal 2 and rotate the tire until it is completely mounted. Once the bead has been mounted, the bead
pressing tool will automatically return to the rest position.
Bead correctly positioned over the left side of the
mounting tool and under it on its right side, thus it
can be slightly lowered for easy tire mounting.
Ensure that the Rim and Tire always spin together.
Important: Always read and follow operating instructions. • 19
Infl ation
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.
Manual Release Valve
If you change tires defined as truck tires,
they must be inflated per OSHA instructions.
1. Ensure 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 deflation button (fig. 27). Inflation hose must
be attached to the valve stem. 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 28).
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.
Figure 27 - Location of Deflation Button
Figure 28 - Do Not Use a Hand-held Style Air Chuck
Explosion Hazard
Never exceed 40 PSI while
seating beads. If you use
more than 40 PSI always
use safety cage.
Remember R.I.M.
(see page iv and back cover)
Explosion Hazard
Never infl ate tire
above
manufacturer’s
recommended
pressure after
bead is seated.
20 • Important: Always read and follow operating instructions.
Stages of Infl ation 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. For tires requiring more than 40
PSI to bead seat use safety cage.
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.
Important: Always read and follow operating instructions. • 21
Mismatched Tires and Wheels
Never mount and inflate mis-matched tires and
wheels.
Mismatched tire and wheel combinations will explode,
if you attempt to force a bead seat, causing personal
injury or death to operator and/or bystanders.
22 • Important: Always read and follow operating instructions.
NOTE: Sometimes, regular inflation may not be enough to seat the bead of tubeless tires.
This problem may be solved by using the optional accessory TUBELESS INFLATING DEVICE.
Tubeless Tire Infl ation
In order to properly use the optional Tubeless Inflating Device:
Press the safety valve against the rim border, push the activating
button on the handle to blast air and press the inflating pedal 4
to provide air to the wheel valve.
During the inflation stages (and especially during the bead seating operation), you must wear
appropriate personal protective equipment to protect your hearing from possible blast injuries
and from noise levels that sometimes exceed the permitted threshold.
Also use appropriate protection equipment to protect your eyes from possible debris that might
fly due to the high pressure air involved in tire bead seating.
Due to the high pressure air that comes out of the jet when operating the inflating device,
hold the handle firmly with your hand to avoid any backlash.
Important: Always read and follow operating instructions. • 23

Standard Maintenance
Routine maintenance according to the following instructions is of crucial importance to ensure the correct
operation and lasting life of the Tire Changer.
Unplug the unit from electrical power source and compressed air supply before servicing it.
Release the compressed air from the circuit by pressing the deflation button 14 for a few seconds.
On daily basis, keep the machine clean of any dirt to ensure the smooth movement of slides,
carriages, and tools and to ensure the correct functioning of clamping chuck and locking systems.
On daily basis, check for worn or damaged plastic mounting tool inserts and plastic and rubber
protections in order to protect alloy rims.
In case of wear or damage, replace them with new inserts and new protections.
Every 2-3 days, check the oil
dropping into the cup (1 drop
every 4-5 activations of the bead
pressing arm or of the bead
loosening system). If necessary,
turn the screw on the top of the
cup with a screwdriver.
Periodically check the oil level which should be kept above
the container trasparent part.
If necessary, unscrew the cup
and topoff by adding oil for
pneumatic systems.
(Chevron Regal® R&O 32)
For long lasting correct
functioning of the pressure
limiter device, check on
regular basis and discharge
the condensation when
needed.
If necessary, drain the
condensation by turning the
drain tap clockwise (keep
the pneumatic supply ON to
perform this adjustment).
On monthly basis, unplug
the machine from pneumatic supply and remove
the filter cup to clean it of
possible solid impurities.
On periodical basis, clean the sliding guides of the bead loosener carriage with naphtha and lube them with oil
or proper grease. Perform the same cleaning and lubricating actions on every junction and mechanical slide.
On periodical basis, check the tensioning of clamping chuck rotation driving belt. If necessary, use a 13mm
wrench to loosen the mounting bolts of the motor support plate, then adjust the belt tension by turning the
tensioning screw and retighten the mounting bolts.
Important: Always read and follow operating instructions. • 27

ONE WORD FOR SAFETY
R.I.M.
READ INSPECT MOUNT
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.
BE CAREFUL OF THESE SITUATIONS:
1. Damaged Bead or
Beads.
2. Rusty Wheels.
(particularly in the
bead seat area)
3. Bent or Cracked
Wheels.
4 A. Mismatched.
(A mis-match of a
16-inch tire to a 16.5inch rim causing an
explosion)
4 B. Mismatched.
(16.5-inch tire on a
16-inch rim)
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.
5. Walk-In Tire and
Rim.
6. Back Injuries.
7. Hand or Finger
Injuries.
(Hands or fingers too
close to inflating tire
or bead seats which
may cause injury.)
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.
8. Standing Clear.
(Never put any part
of your body over the
tire changer during
inflation.)
9. Beads will not
Seat at 40 PSI.
10. Improper
Inflation.
Remember R.I.M. (Read, Inspect, Mount) for every tire.
