Personal injury or death can result from sudden suspension cylinder movement.Sudden movement, up or down, can cause the clearance above your head to change rapidly.Read all warning labels on the suspension cylinders before servicing. Do not check the oil in the suspension cylinder until all the nitrogen pressure has been released.Do not, under any condition, remove valves, cover or plugs from the cylinder unless the rod is fully retracted and all the nitrogen pressure is released.Do not stand under the machine when testing or adjusting the suspension cylinders.
The suspension system on the machine consists of two suspension cylinders and an suspension accumulator. When the suspension system is charged with the proper amount of oil and nitrogen, the suspension system should provide an easier ride for the operator.Note: These procedures are intended to be used in order to maintain the correct suspension system charge. See Testing And Adjusting, "Suspension Cylinder Oil Requirements" for procedures for assembly of a new suspension cylinder or of a rebuilt suspension cylinder.Conditions For Servicing
