EHP Series Operation Instructions
TURNTABLE & CABINET FEATURES
TURNTABLE PLATFORM - Provides easier access to tires
lower bead during the tire changing process.
INTEGRATED BEAD SEATING JETS -Airinflationjets are
integrated into the turntable clamping jaws to insure full bead seating
force directly into the tire cavity regardless of tire diameter.
ADJUSTABLE BEAD BREAKER OPENING-Simple two
position bead breaker pin adjustment allows for readjusting breaker
to fit larger OD tires. (System III only)
TWIN CYLINDER CLAMPING POWER - Two cylinders provide
uniform clamping pressure throughout the stroke (regardless of rim
sizes) as well as providing 25% more clamping power than most
single clamping cylinder tire changers. Additionally two samller
cylinders reduce the critical turntable to cabinet distance, reducing
the stress on the transmission.
WHEEL CLAMPS
UNIQUE SIX POINT CONTACT CLAMPS
Provide better gripping capability regardless of dirt and
moisture.
REDUCEDANGLECLAMPS
Increases clamping contact area with rim insuring no slippage.
NYLON INSERT SOFT TOUCH CLAMPS
Single sided nylon insert in the clamping jaws provides non-
metal touch in critical customer visible areas.
VALVE CORE/TIRE TOOLSTORAGE
On tire changer storage area for valves, tools, caulk, etc.
IN-COMINGAIRPRESSUREGAUGE
Ergonomically located air gauge allows easy monitoring of incoming
air pressure.
INTEGRATEDPRESSURELIMITER
Integrated safety pressure limiter stops air flow once tire pressure
has reached approx. 55 PSI preventing accidential tire over-inflation.
MOUNT/DEMOUNT ARM ASSEMBLY
SURGE TANK IN THE TOWER - Space saving design integrates
the air storage surge tank in the tower allowing for flush to wall tire
changer installation
ADJUSTABLE SLIDEWAY - Unique adjustable mount/demount
shaft slideway allows for easy operator adjustment to compensate
for any cumulative wear in the slideway causing mount/demount
head movement.
NON-SCRATCH NYLON INSERT - Integrated into the mount/
demounthead is a replaceable scratch resistent nylon insert
protecting against accidental rim contact.
SAFETY RESTRAINT ARM (Optional)
TIRE/RIM ASSEMBLYRESTRAINT - Safety Restraint Arm
positively restrains tire and rim assembly to the tire machine during
the inflation process reducing potential for injury caused by the
unlikely event of castrophic tire or rim failure.
SIMPLE SWING ARM DESIGN - SRA arm easily swings to the
left when not in use allowing the technician to quickly and safely
perform the inflation process without disrupting the tire changing
procedure.
GRAVITY LOCK - SRA lock mechanism operates without any
mechanical cam system eliminating the possibility of system
deterioration or misadjustment from mechanical wear.
POSITIONING SAFETY INTERLOCK SWITCH - Integrated
switch insures that SRA arm is centered on the tire/rim assembly
before the inflation process can begin.
ANTI-ROTATION LOCK - Prevents SRA from rotating during
inflation process.
CONSTRUCTIONDESIGNEDFORDURABILITY
RUST PROOF VALVES AND CYLINDERS - Critical bead
breaking cylinder is lined with rust-proof polyfiber liner for years of
rust free operation. Non-lined cylinders will pit causing bead
breaker power loss.
LIFETIME LUBRICATED POLYMER VALVES - Critical
footvalves fabricated from glass/fiber self lubricating material
providing years of maintenance free operation.
WATER SEPARATOR ANDAUTOMATIC OILER - Lubricates
all air used for machine operation, does not lubricate air used for tire
inflation, as do some competitive models.
HIGH TORQUE 1HP MOTOR - Industrial strength high torque
turntable drive motor eliminates tire remount stalling on low profile
high performance tires (UL/CSA approved ).
5 YEAR TRANSMISSION WARRANTY - Designed for
extremely heavy use the critical motor to turntable transmission
linkage carries a full five (5) year replacement warranty.

factory dismounted for a more compact shipping pack-
age.
A. Cut the plastic tie strap which secures the Breaker
Arm to the cabinet pivot.
B. Remove the “C” clip from the top of the pivot pin, slip
the pin out of the hole.
C. Place the Breaker Arm into position and insert the
pivot pin through the top and bottom holes.
D. Replace the “C” clip retainer onto the pivot pin.
E. Locate the spring located at the rear of the pivot
mount. Place the free end of the spring onto the “ear”
located on the Breaker Arm just forward of the pivot.
HINT: You may tie a small rope or cord onto the free end
of the spring, run the cord through the hole. Pull the
spring end toward the ear and loop free end over.
2.3 AIR INSTALLATION
THE AIR INSTALLATION MUST BE MADE ONLY
BY QUALIFIED PERSONNEL.
EXCESSIVEAIR PRESSURE CAN SERIOUSLY IN-
JURE PERSONNEL AND DAMAGE THE MACHINE.
Ensure that the line pressure is within the limits re-
quired by the machine. If the pressure exceeds 170 psi
(12 bar) it is mandatory to install a pressure regulator
before the air inlet of the machine.
If the air pressure is lower than the minimum required
of 110 psi (8 bar) the clamping power of the turntable
and the bead breaker power may be insufficient for cer-
tain tires and substantially reduces tire changer perfor-
mance.
It is suggested that the air supply be equipped with a
water separator/dryer type modification for maximum
performance.
After ensuring all the above proceed as follows:
A. Connect the machine to the air supply with a rubber
hose (rated for the pressure) with an internal diameter
of no less than 1/2" (12.5mm).
WARNING!
BEFORE CONNECTING THE
MACHINE TO THE AIR SUP-
PLY BE SURE ALL PERSON-
NEL ARE CLEAR OF THE MA-
CHINE AND NO ITEMS ARE
LEFT ON THE TURNTABLE.
B. It is recommended that an air valve shut-off be in-
stalled between the shop air supply and the tire changer
in case of air line or filter failure.
C. Should you install any optional accessories, please
refer to the relevant instructions.
D. Ensure the functional ability of the air lubricator by
ensuring that the glass site bowl is filled with air lubri-
cant.

4.0 MOUNTING AND DEMOUNTING PRECAUTIONS
IMPORTANT!
BEFORE MOUNTINGATIRE ONA RIM, PAYATTENTION
TOTHE FOLLOWING:
A.THE RIM MUST BE CLEANAND IN GOOD CONDITION:
IF NECESSARY CLEAN IT AFTER REMOVING ALL
WHEEL-WEIGHTS INCLUDING ‘TAPE WEIGHTS’INSIDE
THE RIM.
B. THE TIRE MUST BE CLEANAND DRY, WITHOUT ANY
DAMAGETO THE BEAD.
C. REPLACE THE RUBBER VALVE STEM WITH ANEW
ONE OR REPLACE THE ‘O’RING IF THE VALVE STEM IS
MADEOF METAL.
D. IF THE TIRE REQUIRES A TUBE, MAKE SURE THE
TUBE IS DRY AND IN GOOD CONDITION.
E. LUBRICATION IS NECESSARY TO MOUNT THE TIRE
CORRECTLYAND GETAPROPERCENTERING.BE SURE
YOUARE USINGAPPROVED LUBRICANT ONLY.
F. MAKE SURE THE TIRE IS THE CORRECT SIZE FOR
THE RIM.
4.1 DEMOUNTING TUBELESS TIRES
A. Remove all wheel-weights from the rim. Remove the
valve stem or valve stem core and deflate the tire (Fig.11).
535a
Fig.11
B. Break both beads.
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 12). Ensure that the Tire/rim assem-
bly is against the rubber breaker pads on the side of the
machine. Make certain that the bead breaker blade is
not over the top of any portion of the rim. Now activate
the bead breaker pedal. As soon as the bead dislodges
from the rim, release the breaker foot pedal. It may be
necessary to rotate the tire 90 degrees and repeat the
above procedure to dislodge all beads.
Pay extra attention during this operation as it easy to
mistakenly keep your foot on the bead breaking pedal
too long. This could potentially result in bead or rim
damage
(Fig.12)
536
Fig.12
NOTICE!
ON “RUN FLAT”TYPE WHEELS WITH THE OPTIONAL
LOW PRESSURE SENSOR INSTALLED, BREAK THE
BEADAT 90DEGREES OFFSET FROMTHE VALVESTEM.
DAMAGE TO THE WHEEL AND/OR SENSOR WILL RE-
SULT IF THE BEAD IS BROKEN ATANY OTHER POINT
ON THE RIM.
C. Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the outside and ex-
pand clamps to clamp from the inside.
When clamping small wheels (14" or smaller) from the
outside, set the clamps at a diameter nearly equal to
the rim diameter, before placing the wheel on the
clamps. This will help avoid the possibility of pinching
the tire as the clamps retract.
NOTICE!
TO MINIMIZE THE RISK OF SCRATCHING ALLOY OR
CLEAR COATED RIMS, THESE RIMS SHOULD BE
CLAMPED FROM THE OUTSIDE.

D. Liberally lubricate both beads. Place the wheel WITH
DROP CENTER UP (Fig.13a) on the turntable, and clamp
in position. Hold the tire and wheel down while clamping.
331
Fig.13 Fig. 13a
E. Gently position the mount/demount head in contact
with rim edge, now manually push the lock lever up and
lock it into place. The tool automatically moves verti-
cally up and away from the rim edge. Turn the swing
arm adjustment knob until the mount/demount head
moves horizontally away from the rim flange by approxi-
mately 1/16" (2mm): this is necessary to avoid any rim
contact during the changing process. (Fig.14).
332
Fig.14
NOTE:
EVERY MACHINE IS EQUIPPED WITH SEVERAL RE-
PLACEMENT PLASTIC INSERTS (INSIDE STANDARD
EQUIPMENTPACK). THE PLASTIC INSERTS WILLHELP
AVOID DAMAGE FROM ACCIDENTAL CONTACT BE-
TWEEN THE MOUNT/DEMOUNT HEAD AND THE RIM.
THE PLASTIC INSERTS WILL NEED TO BE PERIODI-
CALLYREPLACED.
MAINTENANCENOTE:
IF THE MOUNT/DEMOUNT HEAD NYLON INSERTS ARE
WEARING OUT PREMATURELY, THE CAUSE IS THE OP-
ERATORS FAILURE TO CORRECTLY SET THE SWING
ARM ADJUSTMENT KNOB, CAUSING THE INSERT TO
INCORRECTLY CONTACT THE RIM.
NOTE:
ONCE THE MOUNT/DEMOUNT HEAD IS POSITIONED
PROPERLY, IDENTICAL WHEELS MAY BE CHANGED
WITHOUT HAVING TO RESET THE HEAD.
F. Insert the mount/demount tool under the bead and
over the support of the mount/demount head. Lift the
bead onto the mount/demount head. To make this op-
eration easier, insure that the bead of the tire, directly
across from the mount/demount head, is in the drop
center of the wheel. Push the tire into the drop center
with your hand or bead depressor tool if necessary.
If desired, the mount/demount tool can be removed af-
ter lifting the bead onto the mount/demount head
(Fig.15), or you may remove the tool after the bead has
been removed.
