SECTION 15 INFLATION PEDAL OPERATION INFLATION INSTRUCTIONS The inflation pedal located at the front of the checks air pressure in the tire; controls the flow of air through the inflation hose. (See Fig. 15.1) Tire inflation is performed in four steps: Restraint, Bead Seal, Bead Seat, and Inflation. Read the explanation of each step and understand them thoroughly before proceeding. DANGER! Fig. 15.1 CHECK INFLATION GAUGE FOR PROPER OPERATION.
SECTION 16 Fig. 16.6 STAGES OF INFLATION Review the following descriptions and diagrams carefully. Refer to them as necessary during wheel restraint, bead sealing, bead seating, and inflation to verify that you are proceeding properly and safely. STAGE TWO / BEAD SEALING WARNING! 1. Remove the Valve Stem Core and position Valve Stem and connect the Inflation Hose. (See Fig. 16.7) THIS DEVICE ACTS AS A RESTRAINT DEVICE ONLY.
3. TIRE INFLATION Position the Turbo-Blast Nozzle to direct air towards the Rim Center just under the Rim lip. (See Fig. 16.9) 4. Depress inflation pedal and open the Turbo-Blast Valve Fig. 16.9 WARNING! KEEP BALL VALVE CLOSED WHEN TURBO BLAST SYSTEM IS NOT IN USE WARNING! CHECK THE FUNCTION OF THE PRESSURE LIMITER REGULARLY AND MAINTAIN IT ACCORDING THE INSTRUCTIONS PROVIDED IN THIS MANUAL FOR SAFE AND PROPER OPERATION. DO NOT TAMPER WITH OR ATTEMPT TO ADJUST THE PRESSURE LIMITER.
STAGE THREE / BEAD SEATING Bead seating usually occurs on the long tapered side of the wheel first and the shorter side last. Bead seating will usually require at least 7 PSI in the tire. 40 PSI is the maximum safe pressure at this stage regardless of tire operating pressure. Most European import cars and many aftermarket alloy wheels are very tight and can be difficult to bead seat. Also note that asymmetrical hump and run-flat tires are extremely difficult to bead seat.
STAGE FOUR / TIRE INFLATION 1. Make sure both beads are seated. When both beads are seated, the tire is ready for inflation. WARNING! 2. Replace the valve core if it was removed. CHECK TIRE PRESSURE FREQUENTLY. NEVER EXCEED 40 PSI WHILE SEATING BEADS. ONCE SEATED, NEVER EXCEED TIRE MANUFACTURER’S RECOMMENDED AIR PRESSURE. TIRES CAN EXPLODE, ESPECIALLY IF THEY ARE INFLATED BEYOND THEIR LIMITS.
SECTION 17 t Check function of the inflation hose pressure limiter/regulator monthly. Always secure/stow the cover if adjustments are made. The pressure regulator should never be adjusted to exceed 60 PSI. MAINTENANCE INSTRUCTIONS Read and follow all the maintenance instructions provided in this manual to keep the machine in good operating condition. Regular inspections and proper maintenance are essential to preventing accidents and injuries. These instructions will help you service the unit.
Mount/Demount Head Cleaning Oiler Adjustment NOTE: This adjustment will require two persons to perform. 1.
