TASK 24-21-00-920-803-A
Remove and Discard Scavenge and Charge Filter Elements

WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.

WARNING: WEAR GOGGLES, INSULATED GLOVES AND OTHER PROTECTIVE CLOTHES. HOT OIL CAN BURN YOUR EYES AND SKIN. IF OIL TOUCHES YOUR EYES OR SKIN, GET MEDICAL AID.

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.

CAUTION: USE ONLY NEW CANS OF OIL WHEN YOU FILL THE IDG WITH OIL OR ADD OIL TO THE IDG. THE CONTAMINATION IN OIL THAT STAYS IN OPEN CANS CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL DECREASE THE LIFE OF THE IDG.

CAUTION: DO NOT USE SOLVENTS THAT CONTAIN CHLORINE TO CLEAN THE EQUIPMENT (PUMP, HOSES, TANK AND FUNNEL) USED TO FILL THE IDG WITH OIL. CHLORINE CONTAMINATION OF THE OIL CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL DECREASE THE LIFE OF THE IDG.

CAUTION: DO NOT OPERATE THE IDG:

IF IT CONTAINS TOO MUCH OIL
IF IT DOES NOT CONTAIN ENOUGH OIL

IF YOU DO, YOU CAN CAUSE DAMAGE TO THE IDG.

CAUTION: DO NOT DO THE SERVICING OF A DISCONNECTED IDG. CONTINUED OPERATION OF A DEFECTIVE IDG CAN CAUSE DAMAGE.

NOTE: Airbus recommends that you do not do the servicing of more than one Integrated Drive Generator (IDG) at a time.
