It will aid in locating the bead lifting on lower bead of the tire (figure 14.
Tire Mounting 1. Before any mounting, inspect tire for damage and verify size match between tire and wheel (figure 16). This information must be read and followed carefully to prevent accidents and injuries during mounting. Mounting a mismatched tire and wheel will cause an explosion before it bead seats during inflation.

Infl ation The inflation pedal, located at the rear of the left side of the machine, controls the flow of air through the Tire inflation is performed in three steps: BEAD SEAL, inflation hose, and has three positions. BEAD SEAT, and INFLATION. These steps are explained Note: The clip-on chuck on the end of the hose is a in detail on page 14.
Bead Sealing 1. Remove the valve core from the valve stem to allow more air flow into the tire to assist with bead seal. Use of bead sealing jets without a tire in 2. Position valve stem in front of operator and con- place can cause dirt and debris to be blown nect the inflation hose with the clip-on chuck.
Bead Seating 1. Once tire pressure is indicated on the air gauge (inflation pedal in position 1; foot removed from pedal), continue to inject air into the tire (inflation pedal posi- tion 2) in short intervals. Check the pressure frequently. Stand back during bead seat.
Inflation WARNING NEVER exceed tire manufacturer’s recom- mended air pressure. Tires can explode, especially if inflated beyond these limits. Use clip-on air chuck, keep hands, arms and entire body back from inflating tire. Avoid distraction during inflation. Check tire pressure frequently to avoid over infla- tion.
Stages of Infl ation on a Conventional Tire and Rim Review these descriptions and diagrams carefully. Refer to them as necessary during bead sealing, bead seating, and inflation to verify that you are proceeding properly and safely. Bead Sealing Bead sealing is the process of capturing air pressure between the tire and the rim.
Mismatched Tires and Wheels Never mount and inflate mis-matched tires and wheels. Mismatched tire and wheel combinations will explode, if you attempt to force a bead seat, causing personal injury or death to operator and/or bystanders. 16 • Important: Always read and follow operating instructions.
