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.
Front Suspension Cylinder

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) Distance of exposed chrome | |
Measure the distance of exposed chrome (X) for the front suspension cylinders. Compare the present distance to the distance from the previous time. If you do not have those dimensions, 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.
Rear Suspension Cylinder

(Y) Distance between the pins | |
Measure distance (Y) for the rear suspension cylinders. Compare the present distance to the distance from the previous time. If you do not have those dimensions, 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.
