1. Read and observe all precautions concerning assembly, maintenance, and operation of the hydraulic system. Instructions are provided with the hydraulic pump and with the cylinder used in this unit.Contact Caterpillar Service Technology Group if such literature is missing or additional copies are needed.Jackstands shown above are in the shortest and tallest configuration, connected in parallel to the 4C5809 Pump Group.Each jackstand can lift 72186 kg (159000 lb) with the pump pressure at 68900 kPa (10000 psi). Power two jackstands with one 4C5809 Pump Group (10) and the 4C5807 Tee Connection (9) to lift one side or end of very heavy vehicles. This minimizes local stresses on the vehicle and provides best stability when the load is on the stands.Control the rate of lift for each jack using needle valves (25) in the Tee connection group.A single jackstand can be connected to the pump when load and stability requirements are lower. (The jack lifting speed will double.)* Be sure hoses and connections are undamaged and properly tightened before applying hydraulic pressure.* If necessary, use spacers (7) under the load cap (29) to extend the auxiliary extension a MAXIMUM of 254 mm (10") before starting to lift the load.* Lift the load no higher than necessary. Excessively high lifts usually result in greater side loading and reduced stability.* Control the lift rates with needle valve (25) when using parallel connection.* Place jackstands only at recommended points.* Never attempt to lift a load with stand transport wheels extended.* When the load is lifted to desired height, secure it with the two double pins (4) through column and extension.* NEVER leave the load on the stands without the locking pins installed.* Lower the load SLOWLY. Sudden release of hydraulic pressure will activate the fluid velocity valves, locking oil in the jack cylinders. Apply pressure to the cylinders to unlock the valves.* Lower the jackstand extensions fully after use. A special valve in the pump aids retraction of unloaded jack cylinders.* Before moving the jackstand to a new location, the long extension should be fully retracted to avoid the possibility
