Hydraulic Feed Operating Instructions
Fluids
Handle pressurized hydraulic fluid carefully. Escaping pressurized hydraulic fluid has sufficient force to penetrate skin causing serious injury. This fluid may also be hot enough to burn. Serious infection or reactions can develop if proper medical treatment is not administered immediately.
Premium hydraulic fluids containing high quality rust, oxidation, and foam inhibitors are required. These include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic transmission fluids meeting Allison
Hydrostatic Pump Start Up Procedure
Hydrostaticpressure controlledbythe crossoverreliefvalveis factorysetat1750PSI. A 2000 PSI shim kit is availableforextreme conditions.
Follow this
1.Make sure all system components (reservoir, fittings, etc.) are clean before starting the hydrostatic pump.
2.Fill the reservoir with recommended hydraulic fluid (filter before filling).
3.Fill the inlet line leading from the reservoir to the charge pump before
Warning! Do not start engine unless pump is in neutral or detent position on the cable.
4.Start the engine and run at the lowest possible RPM.
5.Refill the reservoir as necessary. The oil level in the reservoir drops and bubbles appear in the fluid as air purges from the unit.
6.Run the unit in both directions for several minutes until any remaining air is purged from the unit. Refill the reservoir as necessary.
7.Loosen a motor fitting and
8.Disengage PTO, check for and correct any fluid leaks, and check the reservoir level. Add fluid if necessary.
•The hydrostatic pump is now ready for operation.
