For Safe Work

The precautions you must observe to ensure safe work are explained below.

Other precautions are found in the main text, accompanied by Danger, Warning, Caution

and Caution.

Use this machine at an inclination angle of within 5except when entering a field or installing the machine

on a truck.

(1) Overview

Carefully read the “Operation Manual (and

operation manual of each option installed),”

“Safety Manual”and instruction of the

agrichemical used, to carry out work correctly and

safely.

Caution

If the machine is to be parked or stored, do

not place anything underneath the booms.

The booms may drop down and damage the

item underneath them

[1] When carrying out work, be sure to wear protective

gears appropriate for each work (helmet, mask and

gloves) and proper clothes.

[2] Before inspecting/servicing or repairing the

machine, stop the engine on flat ground, apply the

parking brake and remove the ignition key. Failure

to do so may cause the machine to suddenly move,

resulting in an accident.

[3] Keep non-operators (especially children) away

from the area where pest control work is

performed. Failure to do so may lead to an

accident.

[4] Exercise due caution not to pollute water supply

systems, rivers, ponds, lakes, etc.

[5] Never refuel near a fire source as it may cause fire.

Refueling while smoking is strictly prohibited.

(2) Items to Note before Operation

[1] Carefully read the Operation Manual and become

familiar with the machine operation.

[2] Apply the parking brake on flat ground and be sure

to perform startup inspection to prevent problems

during pest control work.

Maintenance, P. **

[3] Wipe clean all spilled fuel or oil. If not, fire may

occur.

[4] Dust, fuel or mud attached or deposited on the

wires, muffler and engine area may cause fire, so

inspect and clean these areas before starting the

day’s work.

(3) Starting the Engine

[1] If the machine is operated indoors, exhaust gas will

pollute the air and may cause gas poisoning. Open

the windows and doors and provide sufficient

exhaust ventilation.

[2] Before starting the engine, look around carefully

and give a cue to others indicating that the machine

“will start moving.”

(4) Traveling

[1] This machine cannot travel on local road and must

be carried on a truck, etc., to the field.

[2] This machine can carry only one person. No one

except for the driver can ride the machine. Any

consequence of the machine carrying a person or

persons other than the driver will be the

responsibility of the user.

[3] Do not drive at high speed, take off suddenly,

accelerate rapidly, apply emergency braking or

make a sharp turn unless necessary.

[4] Do not carry a load exceeding the maximum

payload (reagent tank filled with water and

attachments installed). Excessive loading will not

only lead to machine damage, but it may also

cause an accident.

(5) Entering/Exiting a Field (Refer to P.**.)

[1] Enter the field at low speed by orienting the

machine vertically to the furrows.

[2] If there are large height gaps or the approach path

is soft, be sure to use footboards as you enter/exit

the field. Failure to do so may cause the machine to

tip over, creating a very dangerous situation.

[3] Maintain the approach path so that the inclination

angle of approach to the field is kept within 15

degrees.

(6) Loading/Unloading to/from a Truck

(Refer to P. **.)

[1] When loading the machine to a truck, empty the

reagent tank and drive the machine head in. When

unloading the machine, drive the machine slowly in

reverse.

[2] Use a truck whose payload is 2,000 kg or more.

[3] Move the machine slowly using anti-slip footboards

of sufficient strength, length and width (30 cm or

more).

[4] Securely hook the footboards by leaving no height

gap or misalignment on the load-carrying platform.

[5] If the engine of the machine stalls during loading or

unloading, immediately step on the brake pedal

and then gradually release the brake to lower the

machine onto the road.

[6] Choose flat ground and load/unload the machine in

the presence of/with guidance from the assistant.

(7) Chocking the Tires

Prepare concrete blocks, wooden blocks or other

objects that can be used to chock the tires so that the

machine can be parked safely.
