1 Put the 98F10103500000 CHOCK-MLG,ENGINE RUN-UP in position against the wheel.
2 Pull up the tow bar in the top position until it touches the weld stops.
(4) Make a visual check of the temperature sensors, fan inlet and exhaust areas. If snow or ice has collected in the fan duct, make sure that the fan turns freely. Also, make sure that the engine inlet, inlet lip, fan, spinner and fan exhaust duct are clear of ice or snow. If the fan does not turn freely, melt the ice or snow with hot air before an engine operation.

WARNING: DEICING/ANTI-ICING FLUID IS DANGEROUS. USE RUBBER GLOVES AND EYE PROTECTION. KEEP THE FLUID AWAY FROM HEAT AND AN OPEN FLAME. PROVIDE ADEQUATE VENTILATION.

CAUTION: USE ONLY GLYCOL ALCOHOL AS A DEICING/ANTI-ICING MIXTURE. METHANOL CAN CAUSE CORROSION TO ENGINE PARTS MADE OF TITANIUM.

(5) If it is necessary, deice or anti-ice the fan blades with Kilfrost ABC3 (Material No.CP2499) .
(a) Prepare the deicing/anti-icing fluid with the table given below:

4. Procedure
Subtask 71-00-00-710-054-B ** ON A/C NOT FOR ALL

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:

AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:

ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.

CAUTION: DO NOT OPERATE THE ENGINE IF THE FUEL INLET PRESSURE IS NOT POSITIVE. THE FUEL IS NECESSARY TO LUBRICATE THE ENGINE FUEL PUMP AND THE HMU AND THUS PREVENT DAMAGE.

CAUTION: MONITOR THE START CYCLE VERY CAREFULLY WHEN THE STARTER AIR INLET PRESSURE IS LOWER THAN RECOMMENDED (SPECIAL OPERATION CONDITIONS). THIS CAN CAUSE LONGER TIMES TO GO TO IDLE AND HIGHER EGT PEAKS.

A. Do this test:

ACTION	RESULT
1.On the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START.	On the lower ECAM display unit: The ENGINE page comes into view. Make sure that: . the air pressure is between 25 psi (1.7 bar) and 55 psi (3.8 bar). . the oil quantity is correct.
	If necessary, fill the oil tank (Ref. AMM TASK 12-13-79-610-001).
2.On the overhead CTL & IND panel 22VU: Push the ENG/MAN START/1(2) pushbutton switch.	The ON legend of this pushbutton switch comes on.
	On the lower ECAM display unit, on the ENGINE page: The symbol for the starter valve is in the open position.
3.Make sure that the engine operates.	On the lower ECAM display unit, on the ENGINE page: Make sure that the oil pressure indication is positive. NOTE: During cold weather, important oil pressure surges can occur. NOTE: The oil level in the oil tank can go down by 1.6 USgal (6 l). NOTE: If a starter air pressure is used that is less than the recommended level, slow N2 acceleration and subsequent rpm hangup can occur. NOTE: Make sure that you do not go over the starter limits that follow: no engagement of the starter when the core speed is above 20 percent. the acceptable duty cycles can be performed by using one the three following procedures: - 4 consecutive cycles, each of 2 minutes duration with a 20 second rest between 2 consecutive attempts. After 4 cycles, wait 15 minutes to allow starter to cool before you try a new start or motoring. - one 5 minute cycle followed by a cooling period of 2 minutes after the first motoring and a 10 minutes interval between the following ones. - one 15 minute cycle followed by a 15 minute cooling period before you try a new start or motoring. It is recommended to use the 15 minute cycle only for cooling the engine to do a borescope inspection.
4.At 20 percent N2, on the ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to ON. On the upper ECAM display unit: Monitor the main parameters N1, N2, EGT, FF. On the lower ECAM display unit: Monitor the oil pressure.	On the lower ECAM display unit, on the ENGINE page: The AB indication comes into view below IGN. At 50 percent N2: The symbol for the starter valve is in the closed position. The AB indication goes out of view. NOTE: Stall, low fan speed indications will be shown on the upper ECAM DU because Automatic start sequence is being bypassed, abort the start when parameters are close to or above limits. See notes NOTE: Engine light-off will normally occur within 2 to 3 seconds after you set the ENGMASTER control lever to the ON position. If light-off does not occur within 15 seconds, abort the start. NOTE: Immediately abort the start if a fast EGT increase, followed by slow N2 acceleration occurs. These can be symptoms of incorrect fuel scheduling, faulty instrumentation, engine damage, low starter air pressure or too much engine deterioration. Monitor the upper ECAM display unit for possible messages. You can continue starts with slow N2 acceleration from light-off to idle, and followed by a low EGT indication (unsatisfactory fuel schedule). You must correct any starts with temperatures of more than 725 deg.C (1337 deg.F). Normal start temperatures are less than 500 deg.C (932 deg.F)
5.When the engine idle speed is stable, on the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.
6.On the overhead CTL & IND panel 22VU: Release the ENG/MAN/START/1(2) pushbutton switch.	The ON legend of this pushbutton switch goes off. NOTE: It is recommended that the engine operate at or near idle for a minimum of 2 minutes before you increase to high power. You can use taxi-time at or near idle as part of the 2 minutes warm-up time.

5. Close-up
