Any improper handling of the tractor could lead to an accident.
Prior
to the operation of the tractor, be sure to read this Instruction
Manual carefully and have a thorough understanding of the description.
In particular, the instructions given
in "Safety Precautions" must be
strictly followed.
SAFETY PRECAUTION
fl When running the tractor at high speed or on roads, make sure the right and left
brake pedals are interlocked so that they will not be operated independently.
fl Make sure that a guard is in place when operating the belt pulley or P.T.O. driven
shaft.
fl Always wear relatively tight and belted clothing when operating the tractor. Loose
jackets, shirts sleeves or other loose clothing should not be worn because of the
danger of catching them in moving parts, engine or implement.
fl When leaving the tractor, be sure to stop the engine, apply the parking brake and
pull
out the starter key.
fl Never make a sharp turn at high speed.
fl When descending a slope in reverse, be sure not to abruptly operate the clutch or
the brake.
fl Never operate the differential lock when running on a public road.
fl When making a sharp turn, confirm that the differential lock is disengaged.
fl Never operate the tractor on a slope that seems to be dangerous. Do not operate the
clutch, brake, throttle lever and steering wheel abruptly on a slope as it is dangerous.
Be careful particularly when running on a slippery road.
fl Do not carry any persons on the tractor, nor on the linkage drawbars and
implement.
fl When towing, set the hitch point below the center line of the rear axle.
fl When refuelling, be sure to stop the engine. Also take special care so that fuel will
not catch fire.
fl Use a safe fuel container. Fill the tank outdoors and wipe up spilled fuel. Replace
the fuel cap securely.
fl Never touch engine parts after operating the tractor or the engine until parts have
had sufficient time to cool.
fl Always keep positive battery post covered with rubber boot on the end of the cable.
fl Never operate the tractor engine in a closed building where carbon monoxide fumes
can collect.
fl Do not allow children to operate the tractor, nor adults to operate it without
proper instructions.
fl When mounting an implement on the tractor, be sure to follow the instructions
given in "Safety Precautions" in the implement Operation Manual.

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.
