MAKING YOUR TRACTOR A SAFE VEHICLE
How to Maintain Safety
(1) Never attempt to do the following:
• Modification of the structure of the tractor
• Installation of other type of engine
• Installation of tires of other than the original tire
size.
Any malfunctions or failures of the tractor due
to unauthorized modification are not covered
by the warranty.
(2) This machine cannot be driven on a public road
without authorization by a local government
agency, etc.
When transporting an unauthorized machine on a
public road, load it on a truck.
When traveling with an implement wider than the
tractor, put red caution markers such as flags (red
lamps at night) in the most visible locations on
both sides of the implements, and place a “SLOW
MOVING VEHICLE” sign in a place where it is
easily seen by other drivers. Operate the machine
carefully keeping in mind that the implement is
wider and may roll easily. If the implement can
be folded, fold it beforehand. If there are road or
railway crossings where the visibility is poor, you
should install on the machine a mirror to give a
view ahead of you so that you do not need to
move your machine too far into the intersection.
(3) When you travel on a road, you must turn work
lights off if the law requires it.

Starting Engine and Operating Tractor
(1) Before starting the engine indoors, make sure
that there is proper ventilation because exhaust
fumes contain poisonous carbon monoxide, which
cause lethal poisoning.
(2) Before starting the machine, confirm that the
transmission gear has been shifted to the ap-
propriate speed, that there is no one near the ma-
chine, and that the implement is securely installed
on the machine.
Always operate the machine from the operator’s
seat. Never leave the seat except in an emer-
gency when operating the machine.
(3) Before starting to move, pay attention to safety
conditions around the machine to avoid injury to
bystanders or damage to property. Never move
abruptly.
When Traveling
(1) Below are cases where the tractor may overturn.
This list is not exhaustive.
• When you travel on roads, latch the brake ped-
als, 1, together by using interlocking plate, 2, or
the tractor may overturn by 1 wheel locking.
• When you travel on roads, ensure the differen-
tial lock is off.
• Do not make sharp turns when operating at
high speed or for transportation.
• Do not make sharp turns on a slope.

(2) When traveling in a hill, drive the tractor carefully.
• When climbing up a hill, shift the speed change
lever to the most suitable speed. Start moving
the tractor as slowly as possible.
• While climbing up a hill, never shift speeds
along the way.
• When starting to move the tractor on an up-hill
slope, be sure that the front wheels do not lift
up.
• When going down a hill, drive the tractor at
slower speed than used to climb up the hill.
• While going down a hill, never shift into neutral,
and never try to control the speed only with the
brakes; use the engine brake effectively.
(3) When operating on poor footing such as a rough
road, a slope, a road along a ditch or river, or
undeveloped land, drive the tractor at low speeds
and operate it carefully.
(4) When traveling on a road where one or both
shoulders are slanted and which run along a
ditch, look out for softened shoulders especially
when the ditch is full of water and be careful not
to let the machine slip sideway.
(5) Never allow other persons to get on the machine
or the implement except when the machine or the
implement is provided with a seat or a platform
for persons to sit or stand on, and only within the
capacity specified.
Never allow persons to get on the implement
while traveling on roads.
(6) When parking the tractor, you have to park it on
hard, level ground and provide sufficient safety
measures by grounding the implement, removing
the key, applying the parking brakes, and chock-
ing the wheels securely.
(7) Keep inflammable away from the engine during
operation. Especially during stationary operation
do not operate the engine at high speeds so as
not to set fire to grass or straw with a heated ex-
haust pipe or exhaust fumes.
(8) When you have to operate the tractor at night,
make sure of the location of the controls. If not,
the tractor might work unexpectedly by mistake.

Loading onto or Unloading from a Truck
(1) When loading the tractor onto a truck or a trailer,
turn off the truck’s engine and apply the parking
brakes to the truck or the trailer.
Otherwise, the truck could move and the tractor
falls to the ground.
(2) Pay sufficient attention to the safety conditions
around the tractor and have it guided by someone
to assist the operation. Never allow other persons
to approach the tractor, especially in front of or
behind it.
(3) When loading or unloading the machine on / off
a truck, set slip-proof ramps at the same angles
and drive the tractor straight at sufficiently slow
speeds.
Loading the tractor in reverse travel and unload-
ing it in forward travel.
(4) Never depress the brake pedal during loading or
unloading operation, or the tractor may shift side-
ways, which may cause it to fall of the ramps.
(5) If the engine stalls unexpectedly on the ramps,
depress the brake pedal immediately and roll the
tractor to the ground by manipulating the brake
pedal. Start the engine on the ground and try
again.
(6) When the machine is loaded on the truck, stop
the engine, apply parking brakes, and withdraw
the starter key, chock the wheels, and rope it se-
curely to the truck. During transportation, do not
make sharp turns needlessly so as not to shift the
loaded tractor.
(7) Use ramps with the same or better specifications
mentioned below. When the machine is equipped
with attachments, consult your ISEKI dealer for
advice.
Specifications of the Ramps
• Length.....more than 4 times the height of the plat-
form of the truck
• Width (effective width).....more than 35 cm
• Capacity (1 ramp).....more than 1700 kg
• Ramps should have anti-skid surfaces
(8) Hook the ramps securely on the platform of
the truck with the top of the ramp level with the
platform.
(9) Always prepare for even the worst, by never al-
lowing other persons near the tractor.
(10) Drive the tractor carefully at the moment the trac-
tor moves from the ramps onto the platform, for it
changes angle abruptly.
FIG. 16
FIG. 17

SAFETY
13
During Operation
(1) During operation, never allow other persons in
the vicinity of the tractor, because the tractor itself
or flung pieces may cause injury.
(2) Pay attention to safety around the tractor to avoid
injury to bystanders or damage to property. Espe-
cially when operating with other persons, use the
horn to warn them.
(3) When crossing a ditch or a levee or when pass-
ing through soft land, drive the tractor slowly and
straight so that it does not slip or overturn.
(4) Do not touch dangerous parts such as rotating
parts, moving parts, hot parts (muffler, radiator,
or engine, etc.), or electric parts (battery termi-
nals and other live parts), or you may be injured
seriously.
(5) If you use a trailer, use a proper one which suits
your tractor. Using an improper trailer may cause
serious accidents. Never attempt to haul beyond
the tractor’s capacity. If you have a question,
please consult your ISEKI dealer. Follow strictly
the instructions outlined in the operator’s manual
of the mounted or trailed machinery or trailer,
and do not operate the combination tractor
- machine or tractor - trailer unless all instructions
have been followed.
(6) When moving the machine toward an implement
for the purpose of installing the implement, never
allow anyone to stand in between. When installing
the implement on the machine, prepared to move
away promptly in the event of an emergency.
The brakes should be applied securely during
installation.
(7) When front loader is attached, be aware of the
risk of falling object from the loader bucket. Wear
protective headgear such as a helmet. You are
advised to use Falling Objects Protective Struc-
ture (FOPS).
(8) Though tractor is primarily used in agriculture, it
may be used occasionally in a forestry applica-
tion. Pay special attention to the identified below
hazards:
• Toppling trees, primarily in case a rear mounted
tree grab-crane is mounted at the rear of tractor.
• Penetrating objects in the operator’s enclosure,
primarily in case a winch is mounted at the rear
of tractor (e.g. snapping of winch cable).
Falling Objects Protective Structure (FOPS) and
Operators Protection Structure (OPS) are not
standard equipments.
When using FOPS or OPS, consult your ISEKI
dealer concerning the fixation points on tractor for
the FOPS or OPS.

Inspection and Maintenance
(1) Never allow persons listed below to inspect and
maintain the machine.
If any work carried out by unauthorized per-
sons as below would affect the warranty on the
machinery.
• Persons with mental disease
• Persons who cannot inspect and maintain the
machine properly because of fatigue, illness, or
drowsiness from medication, etc.
• Young persons or children too young
(2) When servicing the tractor or mounting or dis-
mounting an implement, place the tractor on level,
hard ground which is sufficiently illuminated, or
unexpected accidents may occur.
(3) When servicing the tractor, follow the instructions
listed below:
• Stop the engine.
• Apply parking brakes.
• Disengage all PTO.
• Place all gear shift levers in neutral.
• Remove the starter key.
• Lower the implement fully, if equipped.
If not, your hands or clothes may be caught or
sandwiched between.
(4) When servicing the tractor, use proper tools. Us-
ing makeshift tools may lead to injuries or poor
servicing, which may result in unexpected acci-
dents during operation.
(5) The engine, muffler, radiator, etc. are very hot just
after operation, so wait until they cool down suf-
ficiently to avoid burns.
(6) Never remove the radiator cap while the engine is
hot or running. Wait until the engine cools down
and then relieve the radiator pressure by releas-
ing the radiator cap. Carelessly pouring cooling
water into the heated radiator can cause serious
damage to the radiator and the engine. Careless
removal of the radiator cap can cause serious
injury because of overheated water vapor.
(7) Never fit unauthorized implements or attempt
unauthorized modification.
(8) Be sure to reinstall the removed safety covers in
place as exposed dangerous parts may cause
serious injury.
(9) Avoid high-pressure fluids. Escaping fluid under
pressure can penetrate the skin and cause seri-
ous injury, so keep hands and body away from pin
holes and nozzles ejecting such fluids. Be sure to
consult your ISEKI dealer about the hydraulic and
fuel injection system trouble.
When checking for leaks, use a piece of card-
board or wood without fail. If any hydraulic fluid
is injected accidentally into the skin, it must be
removed within a few hours by a doctor familiar
with this type of injury. FIG. 22

SAFETY
15
(10) When servicing wheels and tires, the tractor and /
or implement must be supported on suitable
blocks or stands. Not a hydraulic jack.
Do not attempt to service a tire unless you have
the proper equipment and experience to perform
the job. Have the work carried out by your ISEKI
dealer or a qualified repair service.
When seating tire beads onto rims, never exceed
the maximum inflation specifications specified on
the tire. Inflation beyond this maximum pressure
may break the bead, or even the rim, with dan-
gerous, explosive force.
If tire have deep scratches, cuts or punctures,
replace it by qualified personnel as soon as pos-
sible. Wear suitable protective clothing, gloves,
eye / face protection.
Storage
(1) Never cover a hot machine just after operation
with a tarpaulin or the like, or the heated engine
and related parts may cause a fire.
(2) Before storing the tractor for a long period of time,
disconnect the battery cables to prevent them,
in case they are gnawed by a rat, from causing
a short circuit, which may lead to a fire. When
disconnecting the cables, disconnect the negative
(-) cable first.
(3) Safe storage of dangerous objects
• When storing dangerous implements, take ap-
propriate safety measures to prevent accidents
by covering with tarpaulin.
• Store fuel in a safe place with caution signs
such as “PREVENT FIRE” or “INFLAMMABLE”.
• All inflammables must also be stored in a safe,
fire-resistant location.
Dismantling and Disposal
When the machine or its parts completes their useful
life, consult your ISEKI dealer for dismantling and
disposal. If you try to dismantle and dispose by your-
self, be aware of the necessity of hazards and safety
precautions.

MAINTENANCE OF THE ELECTRIC SYSTEM
To Maintain Electric Wiring
(1) When servicing the electric wiring, stop the engine
without fail. Otherwise your hands or clothes may
be caught in or sandwiched between rotating parts.
(2) Before manipulating electric parts, be sure to
disconnect the earth battery cable (-), or you may
get an electric shock or be injured by sparks.
(3) Loose electric terminals or connectors may not only
lower electrical performance but also cause short
circuit or leakage of electricity, which may lead to
a fire. Promptly repair or replace damaged wiring.
(4) Remove chaff or dust from the battery, wiring,
muffler, or engine. Otherwise it could result a fire.
To Handle the Battery
(1) When working around the battery, avoid smoking.
The battery generates explosive hydrogen and
oxygen gases when it is being charged. Keep the
battery away from sparks or open flames.
(2) The battery should be inspected before starting
the engine. Be careful not to touch the electrolyte
when removing the vent plugs. If the battery
electrolyte makes contact with the skin or cloth-
ing, wash it off immediately with water and then
consult a doctor.
(3) When replacing or inspecting the battery, stop the
engine and turn the main switch off, or electrical
parts may be damaged or unexpected accident
may occur. FIG. 24

(4) When disconnecting the battery cables, discon-
nect the earth cable (-) first without fail. When
connecting the battery cables, connect the posi-
tive cable (+) first. Disconnecting or connecting in
wrong order may lead to a short circuit or sparks.
To Handle Booster Cables
When using booster cables, pay attention to the fol-
lowing items for safe operation:
(1) Before connecting cables, remove the vent plugs.
This will lower the force in case of explosion.
(2) Before connecting cables, be sure to stop the en-
gine. Otherwise unexpected accidents may occur.
(3) Use booster cables with sufficient electrical capacity.
A cable of inadequate capacity will cause genera-
tion of heat, which may lead to a fire.
