4.3 INFLATION OF TUBELESS TIRES.
Make sure that both beads are properly lubricated.
Place the wheel in an approved inflation restraint device
to inflate to the correct pressure. Inflate the tire and ensure
that both beads are properly seated.
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
INJURY
SAFETY RESTRAINT ARM (OPTIONAL) MUST BE
IN PLACE PRIOR TO ATTEMPTING BEAD SEATING
OR INFLATION.
NEVER EXCEED THE MAXIMUM PRESSURE
ALLOWED BY THE TIRE MANUFACTURER.
IF YOU CLAMPED THE RIM FROM THE OUTSIDE IT
MUST BE UNCLAMPED WHEN INFLATING BUT
ONLY AFTER THE SRA IS IN PLACE.
THE OPERATOR MUST STAND CLEAR FROM THE
WHEEL WHEN INFLATING, AND PRESSURE MUST
BE MONITORED FREQUENTLY TO AVOID OVER
INFLATION.
BEFORE INFLATING A TIRE, CHECK THE
CONDITION OF THE TIRE AND THE RIM.
Inflate tire according to manufacturer’s recommendations.
Due to unusual configurations or the stacking of tires
the inflation process may be difficult. To assist with
this problem the Snap-on EEWH315A and EEWH317A
Series Tire Changers are equipped with bead seater
jets integrated into the tabletop.
To utilize the bead seater proceed as follows :
A. Position the safety restraint arm (optional) over center
of wheel assembly. The safety arm is lifted upward by
grasping the safety restraint position knob and lifting
upward while simultaneously depressing the anti-
rotation lock arm. Swing SRA arm assembly so the
rubber retainer is centered over the rim. Note that air
pressure to the inflation hose will not flow until the arm
is centered over the rim.
B. Connect the inflation hose to the valve stem.
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. 4.2-3) Position the lower bead on top of
the mount/demount head and UNDER the mounting
finger of the mount/demount head (Fig. 4.2-3). 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 profile tires the bead holding clamp
(option EAA0247G11A Fig. 4.2-4) can help to prevent
the top bead from prematurely seating during the
mounting cycle.
NOTE : Bead Holding Clamp must be removed prior
to coming full circle and impacting the mount/demount
head.
