E254.1 is the preferred lubricant in rotor heads and transmissions only. Use E253 only if E254.1 is not available.
Hydraulic System Servicing
1.
Use fire-resistant hydraulic fluid MIL-H-83282 (E199) (if installed), to service the utility and flight control hydraulic systems. Its
higher flash point provides a greater margin of safety than hydraulic fluid MIL-H-5606 (E197). The two fluids are fully compatible;
however, the presence of more than 3 percent MIL-H-5606 will reduce the fire resistance of MIL-H-83282 proportionately.
2.
The viscosity of MIL-H-83282 increases as temperature decreases. Because of this, it should not be used below -50 F (-46 C). If
temperature drops below this limit control motions may become stiff and sluggish. If this happens, cycle the controls to agitate the
fluid. This along with radiant heat from engines and transmissions, may warm the fluid enough to permit satisfactory operation.
3.
If the controls remain sluggish after cycling and warming, drain the system and service with MIL-H-5606.
