SECTION 1. SAFETY PRECAUTIONS
REMEMBER: "SAFETY" IS ONLY A WORD UNTIL IT IS PUT INTO PRACTICE
Improper handling of the tractor could lead to an accident. Prior to the operation of the tractor, be sure to read this
Manual
carefully and have a thorough understanding of all of the contents. In particular, the instructions given in this
section entitled "Safety Precautions" must be strictly followed.
A. GENERAL OPERATING SAFETY PRECAUTION
A 1. Observe all the safety precautions in this manual
3.
4.
when operating the tractor.
Operate the tractor while wearing tight clothing
that allows easy movement. Avoid loose jackets,
mufflers, ties, scarves, or loose sh irt sleeves to
prevent from being caught by moving parts.
Always work when you are in good physical condi-
tion by taking sufficient rest to avoid overwork.
Do n'ot allow children or adults having no knowl-
edge
of the tractor or tractor operation, to operate
the tractor.
Never allow riders on the tractor, linkage drawbar
or attachments while travelling and operating
them.
B. BASIC SAFETY REQUIREMENTS FOR MAIN-
TENANCE
Always follow these maintenance instructions before
operating the tractor:
1. Immediately repair the head lights and work lamps
required to conform to traffic regulations where
the tractor is operated.
-1-
2. Keep
tractor steps clean to avoid accidents due to
slippage.
Cover the PTO shaft with a guard when not using.
Be sure to apply the brake and lower any attach-
ment or implement before disassembling any part.
Never adjust or service the tractor when it is in
motion or while the engine is running.
Always adjust the brake or clutch properly in
accordance with the adjusting procedure in the
instruction book.
Do not remove the radiator cap while the engine is
running. Shut down the engine and wait until it
cools sufficiently. For removal, turn the cap to
the first stop to relieve pressure. To replace the
coolant, use the coolant recovery tank.
A7. Hydraulic oil or fuel escaping under pressure can
penetrate the skin, causing serious injury. Before
disconnecting oil or fuel lines, be sure to relieve all
pressure. Before restoring pressure after repair,
be sure all connections are tight and all hydraulic
components are in normal condition.
If injured by leaked fluid, see a doctor immedi-
ately for proper treatment.
8. When refueling, be particulary careful first to stop
the engine completely to prevent the fuel from
igniting. Never refuel in the presence of an open
flame or while smoking. Always use funnel when
adding fuel and refuel only out of doors. When
refueling
is completed, wipe any spilled fuel off
the tractor and securely fasten the cap of the fuel
tank.

9. Before starting any work on electrical equipment
or work that may cause you to touch the electrical
part accidentally, first disconnect the battery
cables.
Never remove
the ru bber cap cover at the positive
terminal of the battery cable end.
Before connecting the battery to the charger,
make sure that the charger switch is in "OF'F"
position. Be sure to connect the charger to the
correct term inals on the battery, (positive to
positive, negative to negative).
A
great amount of hydrogen gas is generated by
the battery when it is being charged. Take precau-
tions against fire: do not have any exposed flame
in
the area where you are working.
Be sure not to cause any leakage of the electrolyte,
since it will corrode the skin or clothing. In case
of accident as described below, immediately seek
first
aid, and see a doctor immediately for proper
treatment.
a) If the diluted sulphuric acid from the battery
has gotten into the eyes:
Cleanse
the eyes with a lot of clean running
water for more than 15 minutes, while opening
the eyes widely.
b) If diluted sulphuric acid from the battery has
been swallowed:
Rinse the mouth with clean water immediately
and drink a lot of raw eggs or milk. Lie down
quietly.
c) If diluted sulphuric acid has gotten on the skin
or clothing:
Wash away the diluted sulphuric acid com-
pletely with a lot of clean running water and
neutralize with soap solution. Then rinse with
water.
d) If the diluted sulphuric acid is spilled:
Wash away with a lot of water or neutralize
with slacked Iime or bicarbonate of soda.
A 10. Stop the engine and make sure the PTO shift lever
is in Neutral before performing any of the follow-
ing services, including:
a) Removal of the propeller shaft between PTO
and any attachment,
b) Adjustment of PTO drive train and hitch.
c) Adjustment or cleaning of PTO driven attach-
ment.
11. The steering wheel always has built-in play to
some extent, which is required for smooth mesh-
ing
of sector gear and pinion gear. Always inspect
the amount of the play. Do not operate the
tractor if there is too much or too little play in the
steering.
C. OPERATION OF THE TRACTOR
Before driving the tracotr, follow these rules:
C-1 Before Starting and Driving the Tractor
A Operate the tractor only when seated properly in
operator's seat and keep a firm grip on the steering
wheel at all times. Never attempt to perform any
operation of the tractor from anywhere else, on or off
th e tracto r.
Always wear a "hard hat" when operating the tractor.
C-2 Starting and Driving the Tractor
-2 --
Always operate the tractor at the proper speed which
enables you to keep the tractor under your complete
control.

I
To start travelling, lower the engine speed and release
the clutch pedal slowly. Abrupt releasing causes the
tractor to jump off.
Before leaving the tractor, stop the engine, remove the
key, apply the parking brake and make sure that the
engine has come to a complete stop, and any attach-
ment is completely touching the ground.
A Slow down when operating the tractor on rough round.
A Never attempt to jump on or off a moving tractor.
A When starting the tractor, operating any attachment or
engaging the PTO make sure that no one is in the way,
especially children.
AWhen starting the engine in an enclosed area or build-
ing, ensure
proper ventilation by opening the doors
and/or windows to prevent carbon monoxide inhala-
tion. Mount the extension exhaust pipe on the tractor
which has a cabin.
-r,,)j/
f,") )
-3-

A If the tractor is equipped with ROPS fasten the seat
belt before using the tractor and keep it fastened while
in operation.
A Use of the seat belt is not recommended for ·tractor
without ROPS.
C-3 Travelling
on Roads and Streets
A For travelling on roads and streets be sure to lock both
brake pedals together before driving to prevent either
brake from acting independently.
-4-
A Never operate the differentiallock
speed or travelling on the road.
For drilling the 4-WD tractor on the road, be sure to
place the 4-WD shift lever in OFF position.
C4 Steering and Turning the Tractor
A Slow down your tractor and disengage the differential
lock
before going into a turn, being careful to prevent
any attachment mounted on the front or rear from
hitting anyone or anything.
C-5 Towing and Operating on Hills
A For towing work on downward slope, place the shift
lever in low speed and use engine brake. Never try to
reduce the speed with brake only.
A Towing a heavy object on a hill is highly hazardous.
Widen the tread of the tractor and mount the wheel
weight or chassis weight to increase the stability and
operate with extra caution.
A When operating the tractor on eigher a steep slope or
flat ground, be sure not to suddenly steer, brake or
operate clutch or attachments.
A Do not operate the tractor at the edge of cliff or steep
slope. Be particularly careful right after the rain when
soil is soft and may give way easily.
/
l
•

For towing, be su re to use the drawbar only. Set the
hitch point below the center line of the rear axle. When
using a chain, never try to move forward abruptly.
When using a long chain or cable to hitch the tractor to
the load, drive-the tractor forward slowly until all slack
is taken out.
Avoid operating the tractor on an extreme slope that
appears hazardous, when forced to operate on such
slope, use extra care.
Driving forward out of a ditch or mired condition or
up a steep slope could cause tractor to tip over rear·
ward. Back out of such situation if possible. If the
situation does not permit you to back out, use the
front wheel weight or the chassis weight for balancing
the tractor lengthwise. Also in case any extra-heavy
rear mounting attachment is used, try to obtain better
balance in this manner.
When backing down a slope in reverse gear or going up
the grade in forward gear, never operate the clutch,
brake, th rottle lever or steering wheel abruptly. Be
particularly careful on slippery roads.
A In any case of towing (by use of a rope or by hanging
up the front), be sure to place the both main shift lever
and sub shift lever at "NEUTRAL" position 50 long as
the rear wheels are on the ground.
* These shift levers shall not be placed at any other
speed range.
AWhen starting the engine by towing the tractor with a
battery as discharged, be sure to place the main shift
lever at the 3rd speed step and the sub shift lever at the
high speed step, then operate the clutch slowly.
/). * Never place the sub shift lever at the low speed step.
~ When towing the tractor, be sure to keep the safety
speed. It is advisable to operate at 10 km/h (6.3 mph)
or less in towing the tractor under 20 HP and at
20 km/h (12.4 mph) or less in towing the tractor over
20 HP.
A When towing or running on a steep downward slope, be
sure
to apply the engine brake to keep safety speed.
Never run by inertia (coasting) with main shift
lever placed "NEUTRAL" position or the clutch
disengaged.
C-6 Using
Attachment
To mount or operate attachments, follow the instruc-
tion manual for the particular attachment for safe
operation.
A When using agricultural chemicals with an attachment
on the tractor, always follow the instructions in the
manual for the attachment as well as the instructions
provided by the chemical manufacturer.
C-7 Roll Over Portective Structure (ROPS)
Strongly recommends a ROPS (RollOver Protective
Structure) install to your tractor. A ROPS frame is
available for these tractor. Tractors can be rolled over.
A Always tighten the bolts for ROPS mounting securely.
Exercise good care in seat belt installation as regard
belt strength and the bucket, which must not be
broken off or disconnected.
For further details, ask your delaer.
