Flying Procedure

Precautions for First Flight After Periodic Inspection

Fuel

After your dealer performs the complete inspection flight for the periodic inspection, the fuels are drained from
the fuel tank and the carburetor, to prevent the fuel from becoming old during your storage.
When flying for the first time, create a mixed fuel with fresh gasoline purchased at a gasoline station shortly
before flying (within 1 week), and refuel to maximum capacity.
Never use leftover fuel as it could cause the engine to stop or operate poorly.

Onboard Battery

Since the fuel has been drained, it will take a while before the fuel circulates into the carburetor.
If the engine does not start within 5 seconds after pressing the starter switch, wait about 10 seconds to allow
the battery voltage to recover and the starter motor to cool down. Then, press the starter switch again.
If the rotation of the starter motor is weak, replace the onboard battery, or have your dealer recharge it with the
dedicated recharger.
Never charge with a recharger for car batteries, or connect to a car battery using a jumper cable.
The electronics (computers) in the helicopter could malfunction.

First Flight Procedure

In the periodic inspection, various parts of the helicopter are inspected, and a complete inspection flight is per-
formed. However, when flying for the first time after a periodic inspection, at a practice session, for example,
fly the helicopter gently as a means for the operator to familiarize himself with the various areas of the helicop-
ter as well as its maneuverability.
1 Fill up the tank with fresh fuel. Keep the chemical and water load to one half of the normal load.
2 Perform pre-flight inspection.
3 After the engine starts, take off and hover no higher than 1 m above the ground for 2 minutes or longer.
4 Next, while hovering 2 to 3 m above the ground, fly gently with flare angle of 10 degrees or less, at a flight
velocity of 10 km/h or less, for 10 minutes or longer. During this time, make sure that there is no vibration in
the helicopter, abnormal sound, or other abnormal behavior in response to the various stick operations.
5 When landing for tasks such as refueling, always wait until the engine has stopped, and the main rotor has
stopped rotating, then open the side cover to visually check the coolant and oil leakage.
6 After the flight, perform post-flight inspection, cleaning and servicing tasks.
