TM 9--2350--292--10 PREPARATION OF HYDRAULIC SYSTEM FOR OPERATION IN EXTREME COLD WEATHER +32°F TO --25°F (0°C TO --31°C) 0077 00 THIS WORK PACKAGE COVERS: Preparation of Hydraulic System for Operation in Extreme Cold Weather +32°F TO --25°F (0°C TO --31°C) INITIAL SETUP: Personnel Required Three References WP 0012 00 WP 0056 00 WP 0045 00 WP 0076 00 Before operating hydraulic system in cold weather conditions below 0°F (--18°C), perform the following procedures: 1. Start main engine (WP 0012 00). 2. Close all doors and hatches to crew compartment, except operator’s hatch. 3. Start personnel heater (WP 0056 00) and set selector switch to HIGH position for approximately 30 minutes. 4. Open all hinged subfloor plates in crew compartment to allow the heat to circulate under the subfloor to all mechanical components. 5. Start main hydraulic system (WP 0045 00). 3 1 2 6. Move SPADE operating lever (1) to RAISE position and hold. This causes hydraulic oil to spill over relief valve and warm hydraulic fluid faster. 7. Start APU (WP 0076 00). 8. Move SYSTEM SELECTOR control lever (2) to REFUEL position. This warms auxiliary hydraulic system. 9. Continue to operate system as in step (6) above until hydraulic oil TEMP gauge (3) needle moves off 60°F (15°C), indicating hydraulic oil temperature is at least 60°F (15°C). 10. Operate the Main, Hoist, and Auxiliary winches at a slow speed forward then reverse several times to warm the oil in those units. END OF TASK 0077 00--1/2 blank
