a. Preparation.
The hydraulic oil filter is changed as part of AOAP or whenever the blocked filter warning indicator on instrument panel
is lit.
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 relieving system pressure to zero. Failure to
comply may result in serious 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.

To raise the temperature of hydraulic system oil, operate FEL or backhoe for 5 min.
Ensure hydraulic system is at normal operating temperature. This can be determined by feeling the hydraulic reservoir. It
should be warm.
