Demounting Tube Type Tires; Mounting Tube Type Tires - Snap-On EEWH306A Instructions

®
To utilize the bead seater proceed as follows:
A. Lock the wheel from inside. Outside locking reduces
efficiency.
B. Connect the inflation hose to the valve stem.
C. Lift the tire with both hands so that the upper bead is
sealed to the rim edge (Fig.21).
NEVER STAND OVER TIRE WHEN ATTEMPTING TO
SEAT BEADS OR DURING INFLATION

D. Press the inflation pedal (#1 Fig. 4.3-1) down swiftly
to the end of its travel to activate the bead seater jets.
The top bead is already sealed by the lifting motion.
Therefore, the air from the bead seater jets will enter the
tire impacting on the top sidewall and rebound into the
bottom sidewall driving it into place and creating a seal.
WHEN OPERATING THE BEAD SEATER, ALWAYS
WEAR SAFETY GLASSES TO AVOID INJURY TO EYES.
E. Install valve core, if removed. Complete inflation to
manufacturers suggested pressure. Never exceed
pressure listed on tire sidewall.

position.
NOTICE!

MOUNT/DEMOUNT TOOL, WHEN LIFTING THE BEAD
ON THE MOUNTING FINGER.
After demounting the first bead carefully, remove the tube
before demounting the second bead, as described in
340a
