Handle pressurized hydraulic fluid carefully. Escaping pressurized
hydraulic fluid can have sufficient force to penetrate your 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 C-
3 or Caterpillar TO-2, and certain specialty agricultural tractor fluids.
Follow this start-up procedure when starting a new installation or when restart-
ing an installation in which the hydrostatic pump has been removed from the
system.
1. Before starting the hydrostatic pump, make sure all system components
(reservoir, fittings, etc.) are clean.
2. Fill the reservoir with recommended hydraulic fluid, which should be
filtered before entering the reservoir.
3. The inlet line leading from the reservoir to the charge pump must be filled
before start-up. Loosen the fitting on this inlet line until oil bleeds out.
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. As air is purged from the unit, the oil level in the reservoir will drop and
bubbles may appear in the fluid. Refill the reservoir as necessary.
6. Run the unit and move the control arm in both directions for several
minutes until any remaining air is purged from the unit. Refill the reservoir
as necessary.
Note: A motor fitting may have to be loosened and oil-bled to remove air
from the system (use same procedures as steps 3-5).
7. Check to ensure feed roller stops when control arm is in the neutral
position. Adjust the cable clevis or anchor if the feed roller doesn't stop.
8. Shut down the engine, check for and correct any fluid leaks, and check
the reservoir level. Add fluid if necessary. The hydrostatic pump is now
ready for operation.
