20-4. AIR-TO-OIL COOLER REPLACEMENT.
Prolonged contact with lubricating oil (MIL-L-2104) may cause a skin rash. Skin and
clothing that come in contact with lubricating oil should be thoroughly washed
immediately. Saturated clothing should be removed immediately. Areas in which
lubricating oil is used should be well-ventilated to keep fumes to a minimum.
Ensure engine is cool before performing this task or severe burns from hot hydraulic fluid
The main hydraulic system operates at pressures up to 3,675 psi (25,339 kPa). Never
disconnect any hydraulic line without first dropping pressure to zero. Failure to comply
may result in serious injury or death to personnel.
Equipment may be damaged by foreign matter if hoses and tubes are not plugged and
capped when being removed.
Prevent tubes on air-to-oil cooler from turning when disconnecting hoses. Failure to
comply will cause damage to equipment.
The fins and core of air-to-oil cooler and radiator are easily damaged. Use extreme caution
when removing or damage to equipment may occur.
