opposite the bead head into the rim drop centre.

Continue to rotate the turntable until the top bead 

is mounted. Do not remove the tire tool or bead clamp 

until the foot pedal is released.

4.4  INFLATION OF TUBELESS TIRES.

Make sure that both beads are properly lubricated.

BEFORE INFLATING A TIRE, CHECK THE CONDITION 
OF THE TIRE AND THE RIM.

BEAD SEATING IS THE MOST DANGEROUS PART 
OF MOUNTING A TIRE.

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 
OR DEATH.

NEVER EXCEED THE MAXIMUM PRESSURE 
ALLOWED BY THE TIRE MANUFACTURER.

IF YOU CLAMPED THE RIM FROM THE OUTSIDE IT 
MUST BE UN-CLAMPED WHEN INFLATING BUT ONLY 
AFTER THE SRA IS IN PLACE.

NEVER INFLATE A TIRE USING ANYTHING BUT 
THE INFLATION HOSE ON THE TIRE CHANGER. 
INFLATION OF TIRES USING SHOP AIR IS ONLY 
RECOMMENDED IF THE TIRES ARE IN AN APPROVED 
SAFETY CAGE.

THE OPERATOR MUST STAND CLEAR FROM THE 
WHEEL WHEN INFLATING, AND PRESSURE MUST 
BE MONITORED FREQUENTLY TO AVOID OVER 
INFLATION.

Inf ate tire according to manufacturer’s recommendations.

Due  to unusual con f gurations  or the stacking of tires 

the inf ation process may be diff cult.  To assist with this 

problem the Tire Changers are equipped with bead seater 

jets integrated into the tabletop.

To utilize the bead seater proceed as follows:

A.

 Swing the SRA arm assembly (optional, if equipped) 

so the rubber retainer is centered over the rim.  Note that 

air pressure to the inf ation hose will not f ow until the arm 

is centered over the rim.
