Section 14 MOUNTING TUBE TYPE TIRES DANGER! 1. Lubricate the beads and rim liberally. The clip-on air chuck on the end of the Inflation Hose and all inflation related components should be checked weekly for proper operation. DO NOT USE this machine for tire inflation if any parts are damaged or appear not in proper working order. INFLATION GUN OPERATION The Inflation Gun located checks air pressure in the tire; controls the flow of air through the Inflation Hose and releases air pressure in the tire.
Section 16 3. Pull the Inflation Trigger and hold about to begin air flow through tire valve, the blast of air will expand tire and seal the beads. (See Fig. 16.3) TIRE INFLATION Fig. 16.3 Stages of Inflation Review the following 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. This machine is not intended to be a restraining devise for exploding tires, tubes, or rims.
STAGE THREE / TIRE INFLATION Keep hands and FINGERS clear. Keep entire body away from the tire WARNING! 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. At all pressure levels when inflating through the valve stem, keep hands, arms, and entire body away from inflating tire.
1. Make sure both beads are seated. When both beads are seated, the tire is ready for inflation. 2. Replace the valve core if it was removed. 3. Depress the inflation Trigger Pedal to inflate the tire. Do not stand over tire during inflation. 4. Do not inflate the tire above the manufacturer’s recommended pressure as stamped on the tire sidewall. The typical inflation pressure for automobile tires is between 24 and 45 PSI. Light truck inflation pressure typically covers a wider range.
