TREATMENT OF A NEW TRACTOR
All components of SATOH tractors model S-470 & S-470D are subject to
stringent checking during assembly in the factory. However, a new
tractor should be carefully checked over by the operator himself. For the
first 25 ~ 50 hours operation, heavy duty work should be avoided. If
heavy duty work is unavoidable, drive in a gear one stage lower than you
would normally use, and run the engine at lower speed.
50-HOUR SERVICE
When the tractor is brand new, after the first 50 hours running, the
following service, maintenance and checking should be carried out.
(1) Replace the engine oil filter and engine oil.
(2)
Replace the transmission oil and clean the hydraul ic oil filter.
(3) Retighten all bolts and nuts.
(4) Check and adjust the fan belt tension.
(5) Check the wheels to see if their condition is good and tire pressure is
correct.
(6) Retighten the cylinder head bolts and adjust valve clearances.
(7) Front axle diff. case and gear case oil replacement of 4-wheel drive
tractor.
(8) Cooling water replacement.
(9) Air cleaner element cleaning.
(10) Clean the fuel filter.
(11) Check the front hub for end-play.
(12) Check the battery electrolyte.
This 50-hour Service is an essential procedure for keeping the tractor in
top condition, so it must be done properly.

SECTI N 1.
STARTING AND STOPPING THE ENGINE
Before starting the engine, be sure to check the following points.
1. Confirm that the fuel tank is filled with sufficient fuel.
2.
Check the amount of oil in the engine, and transmission and check
cooling water level.
3.
Always perform the daily maintenance described in SECTION 2.
STARTING
On the S-470 and S-4700, the safety starter switch is provided for pre-
venting unforeseen accidents from breaking out in starting the engine.
Installed between the starter switch and starter motor, the safety starter
switch works as a kind of circuit breaker by which, in case that the
clutch is not disengaged completely, the electric circuit in the engine
starter motor can hardly be closed even when the starter key is turned to
START.
1. Set the throttle lever at the center between idling and high speed.
2. After applying the parking brake, place the main shift lever and
PTa shift lever in neutral. Then, fully depress the clutch pedal.
3. Insert the starter key into the key switch and turn it counterclock-
wise and hold it at "Heat" position to heat the glow plugs. As soon
as the glow signal lamp on instrument panel glows red, about 30
seconds later rapidly turn the key to the "Start" position and the
starter motor will rotate and the engine will start.
-6-

4. When the engine is started, take your hand off the key and the key
then automatically returns to the "ON" position. The key must be
in the "ON" position while the engine is running.
Never
rotate the engine at high revolutions. Run the engine at
approximately 1 ,300 ~ 1,500 rpm and after the engine temperature
rises, shift the throttle lever to SLOW (900 rpm).
5.
After starting the engine, make sure the battery charge warning
lamp,
water temperature warning lamp and engine oil pressure
warning lamp are off.
If anyone of the lamp will not turn off or
light up, stop the engine immediately, check for the cause and then
take necessary countermeasures.
6. If the engine does not start on the first attempt, do not rotate the
starter motor continuously more than 10 sec. Then heat the glow
plug well and
restart the engine.
7. Warm
up the engine especially in cold weather, before working.
STARTING IN COLD WEATHER
1.
Shift the speed control lever to the position of the maximum revolu-
tion, and then the injection pump smoke set is automatically released
and fuel injection is increased.
When
the engine starts the smoke set is automatically reset.
2.
To start the engine in cold weather, heat the glow plug long enough
to raise the temperature sufficiently in the combustion chamber.
NOTES: ________________________________________ _
1)
After the engine has started comfirm that the engine is running
smoothly listening carefully to ascertain if nothing abnormal sounds,
and inspect for oil and water leakage.
2)
In case fuel runs out, be sure to bleed. the fuel system after refilling
the fuel tank; otherwise the engine may not be started (or even
stopped soon after started). (See SECTION 3. BLEEDING THE
FUEL SYSTEM)
IMPORTANT:
h Never use ether to start the engine of model S-470 & S-470D trac-
.. tors.
-7-

STOPPING
After idling the engine for a while by setting the speed control lever at
the appropriate position, bring the throttle lever fully to the "STOP"
position, and fuel is then cut off and the engine will stop.
Be sure to turn the starter key "OFF" when the engine has been stopped.
When the operator leaves the tractor, be sure to apply the parking brake
and take out the key.
INSTRUMENTS AND CONTROLS
TRACTOR METER
The tractor meter, which reads the engine speed and hours of operation,
is mounted on the instrument panel.
The engine speed meter is in the upper portion which indicates the
engine speed in rpm. The hour meter located in the lower center shows
the accumulated running hours at rated engine speed.
-8-

OIL PRESSURE WARNING LAMP
When the starter key
is switched "ON", this lamp glows yellow. When oil
is circulating normally while the engine is running, the lamp turns off. If
the lamp still glows yellow after the engine has been started, stop the
engine immediately and check the engine lubrication oil level.
If that is
OK, check the oil pressure switch and cabling. If there are any defective
switches or cables, replace them.
BATTERY CHARGE WARNING LAMP
When
the starter switch is set to "ON", this lamp glows red. When the
battery is being charged normally while the engine is running the lamp
turns off. If the lamp continues to glow, stop the engine immediately and
check
the alternator, regulator and cabling.
If anything defective is found, replace it.
WATER TEMPERATURE WARNING LAMP
Under normal operating condition,
the warning lamp will not turn on
with
the starter key at "ON" position. When the coolant temperature
rises abnormally, the warning lamp lights up, indicating overheating.
Check
the coolant capacity and fan belt, and recondition, as required.
NOTE:
Utmost care should
be taken when removing the radiator cap with the
engine overheated.
LIGHT SWITCH
The headlight switch
is located on the left side of the instrument panel.

NOTE: ____________________ ~ ____________________ ___
The switch for the working lamp (optional) is incorporated in the light
itself.
SAFETY STARTER SWITCH
As
mentioned previously in this buck, the safety starter switch is pro-
vided on SATOH S-470 and S-470D tractors for preventing unforeseen
accidents at star~ing the engine. Assembled in the engine starting system
betweer, the starter switch and the starter motor, the safety starter
switch works as a circuit breaker in relation to the clutch pedal ope-
rations; unless the clutch pedal is fully depressed to completely interrupt
the power from the engine to the transmission, the safety starter switch
remains off, keeping the starter motor circuit to open even when the
starter key is turned to START.
GLOVlt PLUG
The engine of the SATOH tractors model K3B is fitted with sheathed
type glow plugs wh ich preheat the combustion chamber so that the
engine may be started easily even in cold weather.
-10 -

GLOW SIGNAL LAMP
The glow signal lamp which indicates the heating state of the glow plug
in the combustion chamber is installed on the instrument panel. It is
easily seen from the heating condition of the glow signal lamp resistance
wire.
SPEED CONTROL lEVER
When the speed control lever is pulled fully toward the operator, the
engine speed reaches the maximum of 2,800 rpm.
The rated speed of the engine model K3B is 2,600 rpm. This engine
speed
is not only the most appropriate one to get the longest service life
from your tractor but also the most economical one. It is the best there-
fore,
to run the engine at the rate of 2,600 rpm.
FOOT SPEED CONTROL PEDAL
The foot speed control pedal is installed on the right side of the step.
When the hand throttle lever is in the idling position, the engine speed
can be controlled freely within the range by depressing the pedal.
NOTE:
__________________________________________ __
When the hand speed control lever is in a high rev. position, the foot
speed control pedal also moves into the position for those rev. When this
is done the revolution cannot be controlled by means of the foot pedal
within the range below the rev. set by hand lever.

Depress the clutch pedal fully to bring the machine to a complete halt
when shifting the gear in the transmission for changing the machine
propelling speed. For shifting the PTO gears and shifting the 4-WD gear
follow the similar manner.
Lowering the speed, when the tractor is overloaded, by half engaging the
clutch or changing gear at high speed will damage the clutch lining.
De-clutching must be performed completely in one clean quick move-
ment with the engine revs. lowered as much as possi ble.
NOTE: __________________________________________ __
When the tractor is not used, the clutch should be disengaged by de-
pressing the clutch pedal and the clutch lever should be hooked so that
clutch linings will not get stuck.
BRAKE
The brake on SATOH tractors model S-470 & S-470D is of internal
expansion type and is dirt-and water-proof.
There are two pedals provided on the right side of the transmission case
which are interlocked by a locking plate. The brake is applied by depres-
sing these pedals. To stop the tractor, lower the engine revolutions,
depress the clutch pedal and then the brake pedal. To shorten the
braking distance, lower the engine revolutions quickly, depress the brake
pedal and then the clutch pedal just before the engi ne stops.
For turning in a confined space the right and left axles can be braked
independently by removing the locking plate interlocking the right and
left brake pedals. When travelling at high speed or on roads make sure
that the right and left brake pedals are interlocked by means of the lock-
ing plate.
