speed or for transportation as the tractor may turn
over.
(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) Do not make sharp turns on a slope. It may cause
turnover of the tractor.
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 that 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.
(5) When traveling on a road where one or both shoul-
ders 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.

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 unloading it
in forward travel.
(4) Never depress the brake pedal during loading or
unloading operation, or the tractor may shift sideways, 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 stator
key, chock the wheels, and rope it securely 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 other than those included in the
specifications mentioned below, ask your ISEKI dealer for advice.

(8) Hook the ramps securely on the platform of the trac
tor with the top of the ramp level with the platform.
(9) Always prepare for even the worst, by never allowing
other persons near the tractor.
(10) Drive the tractor carefully at the moment the tractor
moves from the ramps onto the platform, for it
changes angle abruptly.
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. Especially
when operating with other persons, use the horn to
warn them.
(3) When crossing a ditch or a levee or when passing
through soft land, drive the tractor slowly and straight
so that it dose not slip or turn over.
(4) Do not touch dangerous parts such as rotating parts,
moving parts, hot parts (muffler, radiator, or engine,
etc.), or electric parts (battery terminals 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 ISEKI
dealer.
(6) When moving the machine toward an implement for
the purpose if installing the implement, never allow
any one to stand in between. When installing the
implement on the machine, be prepare to move away

INSPECTION AND MAINTENANCE
(1) When servicing the tractor or mounting or dismount-
ing an implement, place the tractor on level, hard
ground which is sufficiently illuminated, or unexpected
accidents may occur.
(2) When servicing the tractor, follow the instructions list-
ed 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.
(3) When servicing the tractor, use proper tools. Using
makeshift tools may lead to injuries or poor servicing,
which may result in unexpected accidents during
operation.
(4) The engine, muffler, radiator, etc. are very hot just
after operation, so wait until they cool down sufficiently to avoid burns.
(5) 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 releasing 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 vapour.
(6) Never fit unauthorized implements or attempt unau-
thorized modification.
(7) Be sure to reinstall the removed safety covers in
place as exposed dangerous parts may cause serious injury.
(8) Avoid high-pressure fluids. Escaping fluid under pres-
sure can penetrate the skin and cause serious injury,
so keep hands and body away from pin holes and
nozzles ejecting such fluids. Be sure to consult your
dealer about the hydraulic and fuel injection system
trouble.
When checking for leaks, use a piece of cardboard 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 or injury.
FIG. 1-20
TG5330,5390,5470

(9) 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 brake
the bead, or even the rim, with dangerous, explosive
force.
If tire have deep scratches, cuts or punctures, the
replaced by qualified personnel as soon as possible.
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 appro-
priate 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 inflammable must also be stored in a safe, fire-
resistant location.

MAINTENANCE OF THE ELECTRIC SYSTEM
TO MAINTENACE 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 discon-
nect 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 of 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 oxy
gen 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 clothing, 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.

When disconnecting the battery cables, disconnect the
earth cable (-) first without fail. When connecting the battery cables, connect the positive 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 following
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 engine.
Otherwise unexpected accidents may occur.
(3) Use booster cables with sufficient electrical capacity.
A cable of inadequate capacity will cause generation
of heat, which may lead to a fire.

INSTRUMENTS & CONTROLS
INSTRUMENT PANEL
FIG. 4-2: Arrangement of gauges. Control switches and
indicators located in instrument panel. Items are detailed
in the descriptions that follow:
Electric Fuel Shut-Off
Turning main switch to off position will stop engine.
Main Switch
FIG. 4-3: Main switch, 1, has the four following positions:
・ p OFF -Tractor engine and all electrical circuits
off.(except for head light, turn/hazard position light,
tail light, working lamp) Key can be removed.
・ O ON - Power supplied to all circuits. Normal operating
position. Linkage on fuel injection pump moves
(electrically) to the run position.
・ f START - Starter activated. This position spring
loaded to ON .
・ G GLOW - Energizes glow plugs to pre-heat combus-
tion chambers and assist starting.
NOTE: Main switch must be turned to ON before any
circuits will operate. PTO switch must be off and
gear shift lever in neutral before engine can be
started.
This tractor is equipped with an electric fuel shut
off. When main switch, 1, is turned to start , on ,
or glow position and gear shift lever is placed in
neutral, a solenoid moves the fuel linkage on
injection pump to run position to start engine.
When main switch is turned to off , solenoid
moves fuel linkage to off position to stop engine.
FIG. 4-4: When main switch, 1, is selected to GLOW
position, glow indicator, 2, will illuminate after several seconds to indicate the engine combustion chambers are preheated and allow cold engine to be started.

Indicator Light Strip
FIG. 4-5: Indicator light strip, 2, contains several warning
lights to monitor certain functions. Currently used positions (from left to right) are:
・ l Main (High) Beam - Illuminates when headlamps in
front grille are selected to high beam position
bylight switch.
・ M Power Take-Off (PTO) - Illuminates when PTO con-
trol switch is moved to engage PTO clutch pack
(PTO operating). Light will go out when PTO switch
is moved to off.
・ o Engine Oil Pressure - Illuminates if engine oil
pressure is low. If light comes on while engine is
running, shut off engine immediately and investigate cause.
・ b Battery Charge - Illuminates when main switch is
turned ON and will go out after engine starts, to
indicate battery is being charged.
Coolant Temperature Gauge
FIG. 4-6: Gauge, 3, indicates engine coolant temperature
when main switch is selected to ON
・ - Shows too cool temperature for severe work.
Allow to warm (needle in mid position) before
applying heavy load.
・ - Indicates overheating (red area on gauge).
Reduce engine speed to idle, allow to run at no
load several minutes and investigate cause (refer
to Troubleshooting ).
CAUTION: Do not service hot engine. Allow to
completely cool before servicing or removing
radiator cap.
Tachometer
FIG. 4-7: Gauge .4, indicates engine speed in crank shaft
revolutions per minute (rpm). Index is also provided to
show rear PTO speed of 540 at approximately 2430
engine rpm.
Normally, the PTO speed should be between 540 and
600. Operating the PTO at a speed above 600 is too fast,
and may result in a breakdown of the tractor or implement.
