RELIEVING HYDRAULIC SYSTEM PRESSURE
If necessary, stop vehicle engine. Place SPRUNG/UNSPRUNG control lever (1) in SPRUNG
Relieve pressure from main accumulator by slowly moving SPRUNG/UNSPRUNG control lever (1)
toward UNSPRUNG position until a hissing can be heard. Hold in that intermediate position until
hissing ceases, then place SPRUNG/UNSPRUNG control lever (1) in SPRUNG position.
Operate each of the four control levers (2) several times, through all positions, to relieve any residual
pressure in hydraulic subsystems.
Slowly loosen hydraulic tank dipstick (3) to allow air pressure to escape. Tighten dipstick (3).
