Improper operation, lubrication, maintenance or repair of this product can be dangerous and could result in injury or death.Do not operate or perform any lubrication, maintenance or repair on this product, until you have read and understood the operation, lubrication, maintenance and repair information.
Read all Warning labels on the suspension cylinders before servicing.The vehicle must be on level ground before releasing the nitrogen pressure.Do not check the oil in the suspension cylinder until all of the nitrogen pressure has been released.Do not remove valves, covers or plugs from the cylinder unless the rod is fully retracted and all of the nitrogen pressure has been released.Do not stand under the machine during suspension cylinder charging, discharging, or testing and adjusting procedures or while lifting or lowering the machine. Sudden movement upward or downward can cause the clearance above your head to change rapidly.Failure to heed this Warning could lead to injury or death.
Dry nitrogen is the only gas approved for use in the suspension cylinders. Charging the suspension cylinders with oxygen gas will cause an explosion. This danger will not happen if nitrogen cylinders with standard CGA (Compressed Gas Association, Inc.) Number 580 Connections are used.When you order nitrogen gas, be sure that the cylinders are equipped with CGA No. 580 Connections. Do not use color codes or other methods of identification to tell the difference between nitrogen cylinders and oxygen cylinders.Never use an adapter to connect your nitrogen charging group to a valve outlet used on both nitrogen, oxygen or other gas cylinders. Be sure you use dry nitrogen (99.8% purity).
When applying an oil charge or a nitrogen charge with the machine on the ground, the machine may suddenly move due to internal sticking of the suspension cylinders.
High Pressure Cylinder. Do not remove any grease fitting, valve or plug until the truck is supported and pressure is relieved or the truck may drop suddenly, resulting in personal injury.Suspension groups should only be serviced by properly trained personnel who have read and understand the service manual procedure to relieve pressure and to charge cylinders.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
