“USE AND DISPOSAL” POLICY CONCERNED WITH ENVIRONMENT PRESERVATION

We try our best to preserve the environment, and are always concerned about our environmental impact at

each step of planning, development, production, distribution, use and disposal of products, and for our over-

all operations through an “environmentally friendly” management system. We comply with international en-

vironmental regulations, environmental regulations designated by country and local authorities and other re-

quirements with which we are in agreement, and we work towards the prevention of environmental pollution

and the conservation of resources. We provide environmental education and have an awareness campaign

to raise environmental awareness among all our employees and members of the supporting companies.

We introduce the “Use and Disposal” policy concerned with environment preservation as follows.

1. Please read the operator’s manual though for global environment protection. Overload on the machine shortens the prod-

uct life and increases the harmful exhaust gas which cause air pollution due to the incomplete combustion.

2. When replacing various uids (for engine, transmission, hydraulics, etc.) by yourself, don’t dispose the used oil to any-

where not recommended. It can pollute the ground and water. Please contact your local dealer to dispose it legally.

3. Observe the operator’s manual and store or dispose the waste product properly. Rust, oil, etc leaked from waste product

improperly stored can pollute the ground and water. Accordingly for a waste product disposal, contact the necessarily “ap-

proved waste collection and recycling facility” to discard the used materials legally.

CAUTION

DPF REGENERATION SWITCH

(1) DPF Regeneration Switch

The DPF (Diesel Particulate Filter) collects

soot contained in the engine exhaust and

reduces exhaust smoke. The soot collect-

ed in the filter must be burned periodical-

ly to prevent the lter from clogging and to

ensure

that the lter can continue collecting

soot. The DPF is regenerated by increasing

the back pressure in the engine and raising

the temperature of the exhaust.

Holding the button down for more than 3

seconds initiates regeneration; the lamp

turns o󰀨 in 30 minutes when automatic re

generation is complete.

parking brake, switch o󰀨 the engine, and

conrm that the PTO lever is on the “OFF”

position.

5. When towing something, make sure to

use the draw-bar.

6. Increase the wheel tread on a slope or

when towing.

7. Depending on the implement, the overall

length may become very long. Pay par

ticular attention to people or objects near-

by when making a turn.

Do not substitute the balance weight with

a person or anything else. Always use

the recommended balance weight.

9. For front loader work, mount an imple-

ment on the rear to keep the balance of

the tractor

10. Read the instruction Mec. of the imple-

ment mounted to the tractor.

CAUTION



High pressure oil leaking under pres-

sure can penetrate the skin and cause

severe

wounds. Avoid danger by re-

ducing pressure before disconnect-

ing hydraulic or other wires. Tighten all

connections before applying pressure.



To check for leakage, use a piece of

cardboard and protect your hands and

feet from the pressurized uid.



3. Fill up the fuel tank. Empty space in the

fuel tank will produce dewdrops that will

produce condensation that will be the

cause of rust formation. And lock the fuel

cock to “C”. (Closed)

4. Disconnect the battery completely

and store it away from the tractor in a

well-ventilated, dry, dark place if possible.

When the battery is attached to the trac

tor, make sure to connect the (+) terminal

rst.

. Change the engine oil and run the en-

gine to circulate oil throughout all the en-

gine parts for about 5 minutes.

. Drain the coolant from the radiator. Af-

ter draining the coolant, attach a tag of

"No coolant, do not start" to the steering

wheel.

If there is anti-freeze in the cool-

ing system, it is not necessary to drain it.

Check the bolts and nuts for looseness,

and tighten if necessary.

8. Add oil, fluid and fuel to each part ac-

cording to the maintenance chart.

Apply a slight coat of grease or oil onto

the tractor parts where is easy to be rust

such as bare metal surface.

10. Inate the tires to a pressure a little high-

er than usual.

1. Place chocks behind and in front of the

rear wheels.

12. Store it in a dry indoor place to avoid

rain or snow and cover the body.

13. Keep the clutch pedal in a depressed

position to avoid rust on the clutch.

14. Put all controls into the neutral position.

STORAGE AND DISPOSAL

USAGE AND DISPOSAL

It is recommended to keep the following to

protect the environment:

1. Overload on the machine shortens the

product life and increases the harmful

exhaust gas which causes air pollution

due to the incomplete combustion.

2. When changing the fluid (engine oil,

transmission/hydraulic oil, and engine

coolant) by yourself, be careful not to

spill it and dispose used oil and cool

ant properly according to the applicable

regulations.

Otherwise, it can pollute the

ground and water.
