NOTICE!
THESE LUBRICATION OPERATIONS ARE NECES-
SARY TO MOUNT THE TIRE CORRECTLY AND GET
A PROPER CENTERING ON THE RIM. BE SURE
YOU ARE USING APPROVED LUBRICANT ONLY.
NOTICE!
SOME TIRES HAVE A COLOR DOT THAT IS TO BE
KEPT ON THE OUTSIDE OF THE WHEEL AND IS TO
BE ALIGNED WITH THE VALVE STEM. IF THIS IS
THE CASE BE SURE TO ATTAIN PROPER ALIGN-
MENT PRIOR TO TIRE INFLATION.
NOTICE !
ON VEHICLES WITH TPMS SENSORS, LOCATE
THE SENSOR (USUALLY WITH STEM) 90 DEGREES
FROM THE MOUNT/DISMOUNT HEAD. DAMAGE
TO THE WHEEL AND/OR SENSOR WILL RESULT
IF THE BEAD CONTACTS THE TPMS SENSOR
DURING THE MOUNT PROCEDURE.
B. Lock the rim to the turntable and rotate it so that
the valve is at the 2 o'clock position. Place the tire
to be mounted on the rim. Swing the mount/demount
arm in so that the mount/demount head is in the
working position. (Fig. 20) Engage the lower bead
OVER the mount/demount head and UNDER the
mounting fi nger of the mount/demount head (Fig.20).
Turn the wheel clockwise (right pedal down) while
simultaneously pushing the tire down into the drop
center, opposite to the mount/demount head.

C. Mount the upper bead following the directions in
section B. With low profi le tires the bead holding clamp
(optional) can help to prevent the top bead from pre-
maturely seating during the mounting cycle.
NOTE: Bead Holding Clamp must be removed prior
to coming full circle and impacting the mount/demount
head.

4.3 INFLATION OF TUBELESS TIRES
Make sure that both beads are properly lubricated.
BEAD SEATING IS THE MOST DANGEROUS PART
OF MOUNTING A TIRE.
NEVER STAND OVER TIRE WHEN ATTEMPTING
TO SEAT BEADS OR DURING INFLATION
IT IS POSSIBLE TO INCORRECTLY MOUNT TIRES
THAT ARE 1/2" SMALLER IN DIAMETER THAN
THE RIM THAT THEY ARE MOUNTED ON. WHILE
THESE BEADS WILL SEAL, IT IS IMPOSSIBLE TO
GET THEM TO SEAT IN THEIR PROPER POSITION.
EXPLOSION OF A TIRE MAY CAUSE SEVERE IN-
JURY OR DEATH.
Infl ate tire according to manufacturers recommenda-
tions.
BEFORE INFLATING A TIRE, CHECK THE CONDI-
TION OF THE TIRE AND THE RIM.
NEVER EXCEED THE MAXIMUM PRESSURE AL-
LOWED BY THE TIRE MANUFACTURER.
THE RIM MUST BE UN-CLAMPED WHEN INFLATING.
THE OPERATOR MUST STAND CLEAR FROM THE
WHEEL WHEN INFLATING, AND PRESSURE MUST
BE MONITORED FREQUENTLY TO AVOID OVER
INFLATION.
Due to unusual confi gurations or the stacking of tires
the infl ation process may be diffi cult. To assist with
this problem the Snap-on EEWH312A and some other
Tire Changers are equipped with bead seater jets
integrated into the table top.
To utilize the bead seater proceed as follows:
A. Position the OPTIONAL safety restraint arm (if
equipped) over center of wheel assembly. The safety
