Stop the machine gradually on a level surface without using the brakes.
Engage the parking brake and stop the engine.
Note: All of the suspension cylinders that are shipped from the factory receive a preliminary charge of nitrogen and a preliminary charge of oil. During field assembly, the suspension cylinders must be charged with nitrogen.

Personal injury or death can occur if personnel are trapped between the wheel and the frame. The steering system is hydraulically controlled and wheels can crush personnel during movement. Use caution when working between the wheels and the frame. If the wheels must be turned, ensure that all personnel are clear of the machine before any movement. |

| (X) Dimension of exposed chrome | |
Measure the dimensions of exposed chrome (X) for the front suspension cylinders. Compare this measurement to the previous measurement of dimension (X). If the dimensions do not match the previous dimensions or if you do not have dimensions from a previous measurement, perform the charging procedure. See Testing And Adjusting, "Suspension Cylinder (Front) - Purge and Charge" for the charging procedure.
Note: There are two relief valves for the grease on the forward side of the front suspension cylinder. These relief valves are located 180 degrees from the lubrication fitting. Do not plug the grease passage of the relief valves.

| (Y) Distance between pins | |
Measure dimension (Y) for the rear suspension cylinders. Compare this measurement to the previous measurement of dimension (Y). If the dimensions do not match the previous dimensions or if you do not have dimensions from a previous measurement, perform the charging procedure. See Testing And Adjusting, "Suspension Cylinder (Rear) - Purge and Charge" for the charging procedure.
Note: When the rear suspension cylinders are properly charged, the left rear suspension cylinder will not show as much chrome as the right rear suspension cylinder. This is due to the rigid frame and to the weight of the cab.
