Proper Management
This unmanned helicopter for industrial applications has been manufactured for the purpose of aerial applica-
tion of agricultural chemicals, fertilizers, and seeds.
Secure a storage location for the helicopter and its auxiliary devices, to prevent theft and illegal use outside of
its intended purpose, such as criminal acts.
To select a storage site, consider factors such as
sources of fire or spark, temperature, humidity,
dust, theft, and the presence of any stacked loads
in the area.
We recommend that you provide a dedicated cabi-
net for storing the auxiliary devices.
In addition to protecting the helicopter from damage
and theft, or the auxiliary devices from loss, these
measures will facilitate the monitoring of their main-
tenance conditions and ensure efficient preparation
for the next flight.
• Store the helicopter, rotors, and transmitters in
separate, lockable locations so that they will not
be stolen or subject to other criminal acts.
• If the helicopter is stolen, immediately file a theft
report with your local police department, followed
by a report to your dealer.
Storage Precautions
Proper Management
8-2
Daily storage procedure
1Perform post-flight inspections (Refer to pages
7-3 to 7-19) and record the results in the flight
log.
2Clean the helicopter. (Refer to page 6-1.)
3Place the cover (sold separately) on the helicop-
ter, and store it indoors, in an area that is not
damp.
4Clean the flight transmitter and remove its bat-
tery. (Refer to page 7-2.)
Long-term storage procedure
If the helicopter will not be operated for a few
months, follow the storage procedure given below
in preparation for the subsequent operation.
1Perform a post-flight inspection (Refer to pages
7-3 to 7-19) and record the results in the flight
log.
2Clean the helicopter. (Refer to page 6-1.)
3Remove the battery from the helicopter and
charge it with a dedicated charger (sold sepa-
rately) (Refer to page 7-1.).
Store the charged battery in a cool, dark area,
and recharge it every 3 months.
4Fuel must be drained from the fuel tank. Request
this operation to be performed by your dealer.
5Place the cover (sold separately) on the helicop-
ter, and store it indoors, in an area that is not
damp.
6Clean the flight transmitter and remove its bat-
tery. Store the battery in a cool, dark area.
The proper procedure for removing the bat-
tery is to first disconnect the negative termi-
nal, followed by the positive terminal.
Reversing this order can cause a short circuit
in the battery.
NNOTICE
Proper Management
8-3
Operating the helicopter after long-term storage
To operate the helicopter after storing it for a few
months, perform the following preparations:
1Install fully charged batteries in the helicopter
and the flight transmitter, after making sure the
main switch on the helicopter is turned OFF.
2Pour fresh fuel in the fuel tank. (Refer to page 4-
4.)
●Have a periodic inspection performed on
the helicopter if you will be operating it
after prolonged storage of 1 year or more.
●If a deletion of registration was filed, apply
for a renewal registration.
●Contact your dealer for details.
TIP
●Do not interchange the cables to the posi-
tive and negative terminals of the battery,
as it can cause a fire or malfunction.
●The proper procedure for connecting the
battery is to first connect the positive ter-
minal, followed by the negative terminal.
Reversing this order can cause a short cir-
cuit in the battery.
NNOTICE
Positive terminal side
Connect the negative
terminal afterward.
Never use old leftover fuel.
This could cause the engine to start or oper-
ate poorly.
NNOTICE
Proper Management

3Perform pre-flight inspections. (Refer to pages 7-
3 to 7-19.)
4Start the engine.
Repeat the cycle of operating the starter motor for 5
seconds and waiting 10 seconds, a few times. This
will allow the fuel to reach the carburetor and the
engine to start.
If the engine does not start within 5 seconds
after the starter switch is pressed, allow the
starter to rest for about 10 seconds. This is
done to allow the battery voltage to recover.
Then, press the starter switch again.

The prescribed types of inspections are described
below.
• Pre-flight and post-flight inspections are to be
performed by the operator.
• For the 30-hour free inspection and yearly peri-
odic inspection, contact your dealer or an autho-
rized service facility for Yamaha unmanned
helicopters for industrial applications.
A Yamaha-authorized service facility for unmanned
helicopters for industrial applications is a service
facility staffed by certified service technicians for
Yamaha industrial unmanned helicopters and
equipped with the prescribed service equipment.
Pre-flight inspection
Ensures that the helicopter and the auxiliary equipment are free of problems before a flight.
See pages 7-3 to 7-19 for details on the inspection.
Inspection Types and Descriptions
For the 30-hour free inspection, periodic
inspection, or general repair, contact your
dealer or an authorized service facility for
Yamaha unmanned helicopters for industrial
applications. Having the helicopter inspected
or serviced by a person who is not autho-
rized to service unmanned helicopters can
lead to a helicopter malfunction or accident.
●Do not fly or perform an aerial application
without having a yearly periodic inspec-
tion performed.
●Failure to perform the inspections
described below invalidates your product
warranty, so be sure to have them per-
formed.

ment are free of problems after a flight.
See pages 7-3 to 7-19 for details on the inspection.
If a problem is detected, promptly contact your
dealer.
Record the results of the inspection on the flight
log. Failure to do so will invalidate your product war-
ranty.

Troubleshooting
The problems listed here can be handled primarily
by the user.
Problems or causes that are not listed here are
handled by your dealer. If such problems occur,
cancel the flight and contact your dealer to have the
helicopter inspected and repaired.
Starter motor does not operate
Unable to start the engine
●Make sure to follow the instructions given
in the “User Action” column, and do not
take any actions that are not documented.
●If you have any questions, be sure to con-
tact your dealer. If an inspection, adjust-
ment, or part replacement is performed by
a person who does not possess the know-
how and proficiency to service the heli-
copter, it could lead to a serious accident.

Warning Lamp Indications
Main Cause User Action
1 Identifiable through the warning lamp operation pattern.
Immediately stop the flight and take appropriate
actions in accordance with the contents of “Various
Types of Warning (Warning, Indication) and Actions”.
Main Cause User Action
1 Fuel temperature is too high
The fuel in the fuel tank gets hot under a scorching
sun. Therefore, keep the fuel tank in a shaded area.
The sensors may operate improperly, depending on
the temperature (they revert to normal when the tem-
perature drops).
2 Possibility of state-of-charge warning of transmitter battery
The state-of-charge warning of the transmitter bat-
tery has the same contents. (The transmitter beeps 4
times (*).) Immediately replace it with a fully charged
transmitter battery.
(* Three sets of 4 beeps, a 4-second pause, and 3
sets of 4 beeps repeated thereafter.)
Speed Control
Main Cause User Action
1 GPS radio signals are not properly received.
Speed control is disabled in this condition. It may be
a temporary matter caused by the surrounding con-
ditions. If it does not revert to normal, contact your
dealer. Moreover, even if it does not revert to normal,
the helicopter can be flown under postural control.
Main Cause User Action
1
Proper GPS radio signals are not being received due to a
poor location of the GPS satellites or the presence of
obstacles.
Immediately turn OFF the GPS switch to see if the
helicopter becomes stable. Often, these situations
are temporary. Wait a while and turn the GPS switch
back ON.
