MAINTENANCE 4.14 EVERY 3000 OPERATING HOURS HOWEVER AT LEAST ONCE A YEAR 4.14.1 SWING GEARS AND MOTOR ADAPTER HOUSING - CHANGE OIL I Legend for illustration Z22882 Swing gears (A) Position of oil level gauge for checking the oil levels (1) Oil level gauge (2) Oil filler plug (3) Breather filter (10) Drain couplings or evacuation nozzles for Wiggins system Motor Adapter Housing (4) Oil level gauge and filler opening. This opening can also be used for connecting a suction pump when changing the oil. (5) Breather filter (6) Oil drain plug Swing Gears, change oil: 1. Use adequate working platform for draining the oil. Place receptacles of sufficient capacity (approx.
100 liter) below drain couplings (10). Attach drain hose (part of tool set) to drain coupling (10). Remove parts (1, 2 and 3) to speed up draining. On swing gears with evacuation nozzle (10), use the Wiggins system for changing the oil. 2. Clean breather filter (3) with compressed air from inside to outside and re-install. 3. After the oil is completely drained, flush the gear with the reg- ular gear oil. 4. Remove drain hose from coupling (10) and attach the protec- tion cap onto the drain coupling. 5. Fill gear housing through filler opening (2) up to the "MAX" mark on level gauge (1) with fresh oil and re-install plug (2).
NOTICE For checking the oil level insert the level gauge (1) but DO NOT screw in, see detail (A). 6. After short operating period check oil level and housings for leaks. 453
