XII. Maintenance and Operations

By following these steps, vehicle owners will obtain the longest life and best results from their air

springs.

1. Check the air pressure weekly.

2. Always maintain Normal Ride Height. Never inflate beyond 100 p.s.i.

3. If you develop an air leak in the system, use a soapy water solution to check all air line connections and the inflation

valve core before deflating and removing the air spring (see page 6).

4. When increasing load, always adjust the air pressure to maintain the Normal Ride Height. Increase or decrease

pressure from the system as necessary to attain Normal Ride Height for optimal ride and handling. Remember that

loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried

directly over the axle.

IMPORTANT

: For your safety and to prevent possible damage to your vehicle,

do not exceed maximum Gross

Vehicle Weight Rating (GVWR), as indicated by the vehicle manufacturer.

Although your air springs are rated at a

maximum inflation pressure of 100 p.s.i. The air pressure actually needed is dependant on your load and GVWR,

which may be less than 100 p.s.i. Check your vehicle owners manual and do not exceed the maximum load listed

for your vehicle.

6. Always add air to springs in small quantities, checking the pressure frequently. Air springs require less air volume

than a tire and inflate quickly.

Should it become necessary to raise the vehicle by the frame, make sure the system is at minimum pressure (10

p.s.i.) to reduce the tension on the suspension/brake components. Use of on-board leveling systems do not require

deflation or disconnection.

8. IMPORTANT:

Check and re-torque all mounting hardware, especially the beam U-bolts, after 100 and 3,000

miles.

10 p.s.i. 100 p.s.i.

Failure to maintain correct minimum pressure (or pressure proportional to load), bottoming

out, over-extension, or rubbing against another component will void the warranty.
