WARNING
Certificate of
Authorization
Make sure to wear a helmet during flight. To
perform an aerial application, make sure to
wear clothing that is appropriate for the oper-
ation. Performing a flight and an aerial appli-
cation in clothing that is not appropriate for
the task could cause loss of visibility, maneu-
vering error, or cause your foot to slip, result-
ing in unexpected accidents. Furthermore, it
could harm your health through exposure to
agricultural chemicals.
WARNING
A minimum of 3 people is required for an
aerial application: a navigator who has been
briefed on the aerial application procedure,
an assistant who readies, mixes, and sup-
plies agricultural chemicals, and an operator.
Beware that an understaffed operation could
lead to an accident.
WARNING
R-max.book Page 3 Tuesday, January 17, 2012 3:08 PM
Safety Precautions
1-4
The operation of an unmanned helicopter
involves considerable mental fatigue. The
operator should not fly the helicopter contin-
uously for more than one hour, but should
take a rest every hour. Prolonged continuous
flight operation could cause the operator to
lose concentration and could lead to an acci-
dent.
WARNING
Do not fly the helicopter after drinking alco-
hol or taking a cold medicine, or if you are in
poor physical condition. Flying the helicopter
in poor physical condition could cause loss
of concentration, and could lead to an acci-
dent.
WARNING
R-max.book Page 4 Tuesday, January 17, 2012 3:08 PM
Safety Precautions
1-5
When operating an unmanned helicopter for the purpose of spraying agricultural chemicals, ensure safe oper-
ation, as well as the safety of humans, animals, agricultural products, and the environment during aerial appli-
cation.
General Flight Pattern for Aerial Application
Example: Disease and pest control of a rice paddy
• Flight altitude: 3 to 4 m
• Flying speed: 10 to 20 km/h
• Flying interval: 5 or 7.5 m
• Wind velocity: 3 m/s maximum
Spraying Precautions
Affirmative!
Just passed 10 meters,
and 5 meters
Flying speed between
10 and 20 km/h
Flying height between
3 and 4 meters
Flying interval 5 or 7.5 meters
Wind
When performing tasks such as refueling,
never approach (or allow others to approach)
within 20 m of the helicopter until the main
rotor has come to a complete stop and the
engine has stopped. Entering within 20 m of
the helicopter could cause a serious acci-
dent.
DANGER
R-max.book Page 5 Tuesday, January 17, 2012 3:08 PM
Safety Precautions
1-6
Using Registered Agricultural Chemicals
Use nationally registered agricultural chemicals,
and use them properly by reading the usage
instructions and precautions included in the manual
for each respective chemical.
Do not use agricultural chemicals other than
those registered. Failure to do so could
expose animals, plants, or people to agricul-
tural chemicals for which the operator will be
held socially responsible.
WARNING
Control and handle agricultural chemicals
strictly in accordance with their manuals.
Negligent control and improper handling of
agricultural chemicals could lead to chemical
pollution or health hazards.
WARNING
R-max.book Page 6 Tuesday, January 17, 2012 3:08 PM
Safety Precautions
1-7
Spray Chemical
Since the agricultural chemical is diluted at a low
dilution rate, make sure to observe the following:
(1) Agricultural Chemical
●Use nationally registered agricultural chemicals.
●In low-volume liquid spraying, the characteristics
of the agricultural chemical can easily change
when mixed with other agricultural chemicals,
and may produce solids or turn to a gum-like
state. When mixing, use agricultural chemicals
that have been checked in advance for physio-
chemical change, compatibility with the sprayer,
mixture toxicity, etc.
●Spreading agents (surface active agents) cannot
be added.
(2) Dilution Water
For dilution water, make sure to use tap water. Do
not use agricultural water, as this could lead to
debris clogging or characteristic change in the agri-
cultural chemical.
(3) Dilution Rate
For example, to make 8 of spray solution of an
agricultural chemical diluted to 8x, dilute 1 of
agricultural chemical with 7 of tap water (dilution
water). This will make 8 of spray solution.
Agricultural chemical: 8 × 1/8 = 1
Tap water: 8 - 1 (agricultural
chemical) = 7
Since flowable and water-dispersible chemicals can
easily precipitate, combine and mix them well just
before aerial application flight.

Pouring the Spray Solution
●Check the inside of the chemical tank (into which
the solution will be poured), the check valve, the
strainer section, and the filter for any debris or
sediments. If you find any debris or sediments,
make sure to remove them before pouring the
solution.
●Keep the chemical tank load to 8 or less per
side (16 combined for left and right tanks).
●For higher altitudes and temperatures,
decrease the load.
●For information on load capacity, see the
operation manual for the helicopter.

Stop the engine when replenishing the chemical.
When replenishing the chemical, make sure to stop
the engine. If this task takes longer than one
minute, turn OFF the main switch on the helicopter.
Securely mount the chemical tanks.
Prior to the flight, check that both chemical tanks
are securely mounted.
Do not apply excessive force on the boom.
When performing tasks such as replenishing the
chemical, use caution not to trip on the boom.
Usage Precautions
Never approach (or allow others to approach)
within 20 m of the helicopter until the main
rotor has come to a complete stop and the
engine has stopped. Entering within 20 m of
the helicopter could cause a serious accident.
DANGER
If the chemical tanks are not securely
mounted, they could come off during flight.
NOTICE
If an excessive force is applied against the
folding direction of the boom, it could
become damaged.

When the chemical tanks are plugged/unplugged,
or when the chemical is sprayed until the chemical
tanks are empty, air pockets will get entrained
inside the sprayer piping, causing the spraying con-
dition to deteriorate.
With the chemical tanks set in place, if the air pock-
ets are not completely released by discharging from
the nozzles, turn OFF the sprayer switch, and
release the air pockets as follows:
1Facing the rear of the helicopter, turn the three-
way cock handle on the rear of the sprayer so
that it points to your left.
2Turn ON the sprayer switch, and run the spray
pump for 5 to 7 seconds.
3Point down the three-way cock to the spraying
position, and verify that the discharge condition
from the nozzle is good.

Spraying Position (pointing down)
When releasing air pockets, do not perform
the task (or allow others to approach the heli-
copter) until the main rotor has stopped
rotating completely and the engine has
stopped.
If you are using the speed-dependent func-
tion and need to release air after receiving
the GPS signal, set the sprayer selector
switch to “”. After releasing air pockets,
return the sprayer selector switch to “”.

Switching Between Nozzles
Set the spray volume switch on the flight transmitter
to “1” (“out” position) to discharge from the right and
left nozzles. Set it to “1/2” (“in” position) to dis-
charge from the center nozzle.
To switch between nozzles, turn OFF the spray
switch, and perform the task after the spray pump
has stopped.

Using the Speed-Dependent Function
1Switch the sprayer selector switch on the flight
control panel to “ ”.
2Set the spray volume adjuster and the spray noz-
zle settings according to “Spray Specifications
Settings” on page 4-7.
If the GPS signal reception is poor (the outer GPS indicator lights are ON), the speed-dependent function
does not work, and the chemical is discharged at a constant rate set by the spray volume adjuster on the flight
transmitter.
During a GPS-controlled flight, if the GPS signal reception worsens (GPS indicator lights cycles a pattern
“outer lights ON > inner lights ON > OFF”), the speed-dependent function does not work, and the chemical is
discharged at a constant rate set by the spray volume adjuster on the flight transmitter.
In this case, immediately turn OFF the GPS control switch according to the operation manual for the helicop-
ter.
●The speed-dependent function can be used only when all of the following three conditions are
met:
• Low-volume liquid spraying at 7.5m spray width, 8L/ha
• Left and right nozzles are selected
• The GPS signal reception is good (i.e. the outer GPS indicator lights are ON)
The state of the flight mode selector switch on the helicopter and the GPS control switch on
the flight transmitter are irrelevant.
●When the center nozzle is used, the speed-dependent function does not work, and discharging is
done in proportion to a constant volume set by the spray volume adjuster on the flight transmit-
ter.
TIP
If the flight velocity exceeds 20km/h, only the
outer lights of the YACS warning lights illumi-
nate. If this happens, drop the flight velocity
to 20km/h or less.

●When you turn all the way towards the (b) direction, and start turning back towards the (a) direc-
tion, the first notch you reach is Level 1.
●Turning in the (a) direction increases the spray volume, and turning in the (b) direction decreases
the spray volume.
●Levels between 32 to 40 use maximum current, therefore, do not use continuously.
●After adjusting the volume, make sure to put the rubber cover back on.
●The spray specifications settings above are only to be used as a guideline. Before the actual
spraying task, make sure to check the spray volume for the chemical you are using.

1Turn the sprayer selector switch to “ ”.
2Mount the chemical tank filled with tap water,
and turn the main switch of the helicopter to
“START”. Press the “ ” switch on the con-
trol panel to clean the inside of the sprayer pip-
ing.
3To switch between the right/left nozzles and the
center nozzle, press the “ ” switch to tem-
porarily stop the pump, then use the “ ”
switch.
4Drain the chemical inside the spray piping
through the drain pipe, by pointing the three-way
cock handle to the right, thereby actuating the
spray pump.
5After draining out the chemical, point the three-
way cock handle to the spraying position (down).
6Remove the filter and nozzles, and wash them
with tap water. (See pages 5-3 and 5-4.)
7If you want to wash the sprayer thoroughly,
remove the sprayer and wash with tap water.
When doing this, use caution to keep the 2-pole
and 3-pole connecters from getting wet. (See
page 3-1.)
Control and handle the agricultural chemicals strictly in accordance with their manuals. Negligent
control and improper handling of agricultural chemicals could lead to chemical pollution or health
hazards.
WARNING
●Clean the sprayer after every spraying work, as the spraying performance could deteriorate due
chemicals solidifying onto the sprayer.
●Use a drain pipe to collect the leftover chemical and cleaning solutions from cleaning into a con-
tainer, and dispose it according to the operation manual for the chemical.
●During winter seasons, the pump or the filter cap may become damaged by frozen liquids. There-
fore, for long-term storage during winter seasons, drain the leftover chemical and remove the fil-
ter cap.
