The air in the pump will work itself back to tank.
10. Perform pump start-up. See below.
Pump Start-up
1. Start the engine and let it idle. Do not allow the engine to
surge or run excessively fast during the initial start-up.
DO NOT OPERATE ANY HYDRAULIC FUNCTION AT
THIS TIME.
2. Let the pump run for about 60 seconds to release any air
that might be in the hydraulic system. Check the suction
hose connections for loose clamps, fittings, etc.
3. Adjust the pump to deliver system pressures. Follow the
instruction under “Adjusting Hydraulic Pressure
Settings,”.
4. Check the level of hydraulic oil in the hydraulic oil tank. If
low, add only pre-filtered hydraulic oil.
NOTE: The variable displacement pump and all other
components require clean, filtered hydraulic oil for
proper operation. Contaminated hydraulic oil may
cause damage to the pump and other components.
Before adding any oil to the hydraulic tank, be sure
it is filtered through a 10 micron (absolute) or less
filter.
