     (a) Ground (earth) the fuel tanker/pump unit and the aircraft correctly (Ref. AMM TASK 12-34-24-869-001).
   (2) Bond the fuel tanker/pump unit to the aircraft (Ref. AMM TASK 12-34-24-869-001).
   (3) Make sure that the chocks do not touch the tires. The weight of the fuel can lower the aircraft and cause the chocks to catch.
   (4) Remove refuel/defuel coupling cap 41QM.
   (5) Make sure that the hose coupling of the fuel tanker/pump unit is clean.
WARNING: MAKE SURE THAT THE FUEL SUPPLY HOSE IS CORRECTLY CONNECTED TO THE COUPLING BEFORE YOU REFUEL/DEFUEL THE AIRCRAFT. DO NOT CONNECT THE FUEL SUPPLY HOSE IF THERE ARE SIGNS OF DAMAGE TO THE AIRCRAFT COUPLING LUGS OR SLOTS.

   (2) Make sure that the chocks do not touch the tires. The weight of the fuel can lower the aircraft and cause the chocks to catch.
   (3) Remove the refuel/defuel coupling-cap 101QM(41QM).
   (4) Make sure that the hose-coupling of the fuel tanker/pump unit is clean.
   (5) Connect the hose-coupling of the fuel tanker/pump unit to the aircraft refuel/defuel coupling.
   (6) Set the fuel tanker/pump unit to the refuel mode.
   (7) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
