b. Release FEL Lift and Tilt Cylinder Hydraulic System Pressure.
· The IHMEE hydraulic system operates at oil pressures up to 3,000 psi (20 680 kPa). Never
disconnect any hydraulic line or fitting without first dropping system pressure to zero. Failure to
comply may result in injury or death to personnel.
· Hydraulic fluid (Dexron III) is TOXIC. Wear protective goggles and gloves; use only in
well-ventilated area; avoid contact with skin, eyes, and clothes. Skin and clothing that come in
contact with hydraulic oil should be washed immediately. Saturated clothing should be removed
immediately. Failure to comply may result in injury to personnel.
Release hydraulic pressure in tilt cylinders by rotating load-holding valve (1) one-quarter to one-half turn only on
both tilt cylinders. After pressure is released, tighten load-holding valve (1) on both tilt cylinders.
Loosen hydraulic fitting (2) one-quarter to one-half turn only between load-holding valve and cylinder on both
FEL lift cylinders. After hydraulic pressure has been released, tighten both hydraulic fittings (2).
c. Follow-On Maintenance.
