Turntable & Cabinet Features - Snap-On EEWH311A Instructions D'opération

EEWH311A Tire Changer Operation Manual
INTEGRATED BEAD SEATING JETS - Air inflation jets 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.
TWIN CYLINDER CLAMPING POWER - Two 3" clamping 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 these two smaller 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.
REDUCED ANGLE CLAMPS
Increases clamping contact area with rim insuring no slippage.
NYLON INSERT SOFT TOUCH CLAMPS
Single sided nylon insert in the clamping jaws provides Nonmetal
touch in critical customer visible areas.
VALVE CORE/TIRE TOOL STORAGE CABINET
On tire changer storage area for valves, tools, caulk, etc.
INCOMING AIR PRESSURE GAUGE
Ergonomically located air gauge allows easy operator monitoring
of incoming air pressure.
INTEGRATED PRESSURE LIMITER
Integrated safety pressure limiter stops air flow once tire pressure
has reached approximately. 55 PSI preventing accidental 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 vertical mount/
demount hex 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/
demount head is a replaceable scratch resistent nylon insert
protecting against accidental rim contact.
CONSTRUCTION DESIGNED FOR DURABILITY
RUST PROOF VALVES AND CYLINDERS - Critical bead breaking
cylinder is lined with rustproof 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 AND AUTOMATIC OILER - Lubricates all
air used for machine operation, does not lubricate air used for tire
inflation, as do some competitive models.
Operation Manual
1.2.1 TURNTABLE & CABINET FEATURES
EEWH311A
HIGH TORQUE 1HP MOTOR - (air-electric models) Industrial
strength high torque turntable drive motor eliminates tire remount
stalling on low profile high performance tires (UL/CSA approved ).
3-YEAR TRANSMISSION WARRANTY - Designed for extremely
heavy use, the critical motor to turntable transmission linkage
carries a full three (3) year replacement warranty.
PNEUMATIC BEAD ASSIST ARM
Up/Down Control Switch - Toggle switch allows single finger
operation of all pneumatic PBA functions, with or without gloves.
Top Bead Roller - Provides easily controlled pneumatic power to
drive upper beads down into the wheel drop center (while tire is
turning) for easy lubrication prior to dismounting. Also provides
pneumatic power assistance for safely remounting second bead
on extremely low profile and Run Flat design tires.
Bead Depressor - Provides easily controlled pneumatic power to
depress the tires sidewall during the remount cycle. This will prevent
premature bead seating before the entire bead has been reinstalled
on the wheel. Provides an added level of safety by keeping the
technicians hands away from the bead area during this potential
pinch point procedure. Additionally the Bead Depressor "follows"
the tire around while turning to guarantee successful remount first
time everytime.
Bottom Bead Roller - Provides easily controlled pneumatic power
to unseat stubborn lower beads which may have accidentally
reseated after the original bead breaking procedure. Also allows a
technician to raise and hold wider tires up, to assist in safely and
easily getting the second bead up onto the mount/demount head.
Wheel Centering Depressor - Provides downward pressure on a
rim when working to clamp a low profile tire/rim combination. Will
assist the technician in correctly seating the rim clamps between
the tire and the rim when clamping from outside in where it is difficult
to depress the tire sidewall enough to expose the rim edge.
SAFETY RESTRAINT ARM (OPTIONAL)
TIRE/RIM ASSEMBLY RESTRAINT - Safety Restraint Arm
restrains tire and rim assembly to the tire machine during the
inflation process reducing potential for injury caused by the unlikely
event of catastrophic 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 mis-adjustment 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 horizontally
during inflation process.
