Discard used engine oil and other oils properly.
13.6.2. Cooling System
A. Changing Coolant
(1.) To drain coolant, always open both drain cocks and
simultaneously open the radiator cap as well. With the
radiator cap kept closed, a complete drain of water is
impossible.
(2.) Remove the overflow pipe of the radiator pressure cap to
drain the reserve tank.
(3.) An improperly tightened radiator cap or a gap between the
cap and the seat quickens loss of coolant.
(4.) Coolant (Radiator cleaner and anti---freeze).

B. Remedies for quick decrease of coolant
(1.) Check any dust and dirt between the radiator fins and tube.
If any, remove them from the fins and the tube.
(2.) Check the tightness of the fan belt. If loose, tighten it
securely.
(3.) Check the internal blockage in the radiator hose. If scale
forms in the hose, clean with the scale inhibitor or its
equivalent.
C. Checking Radiator Hoses And Clamp
CAUTION
BE SURE TO CHECK RADIATOR HOSES AND HOSE
CLAMPS PERIODICALLY. IF RADIATOR HOSE IS DAMAGED
OR COOLANT LEAKS, OVERHEATS OR SEVERE BURNS
COULD OCCUR.
Check to see if radiator hoses are properly fixed every 200 hours
of operation or 6 months, whichever comes first.
(1.) If hose clamps are loose or water leaks, tighten hose clamps
securely.
(2.) Replace hoses and tighten hose clamps securely, if radiator
hoses are swollen, hardened or cracked.
Replace hoses and hose clamps every 2 years, or earlier, if
checked and found that hoses are swollen, hardened or cracked.
D. Precaution At Overheating
Take the following actions in the even the coolant temperature is
nearly or more than the boiling point, what is called
“Overheating”. Take these action if the engine‘s alarm buzzer
sounds or the alarm lamp lights up.
(1.) Stop the engine operation in a safe place and keep the
engine unloaded idling.
(2.) Do not stop the engine suddenly. Stop it after about 5
minutes of unloaded idling.
(3.) If the engine stalls within about 5 minutes of running under
no load, immediately leave and keep yourself away from the
machine. Do not open the hood and any other part.
(4.) Keep yourself and others well away from the engine for
further 10 minutes or while the steam blown out.
(5.) Checking that there gets no danger such as burn, get rid of
the causes of overheating see 14. TROUBLESHOOTING
section of this manual. And then, start again the engine.
E. Cleaning Radiator Core (Outside)
If dust is between the find and tube, wash it away with running
water.
NOTE
Do not clean radiator with firm tools such as spatulas or
screwdrivers. They may damage specified fin or tube. It can
cause coolant leaks or decrease coolings performance.
F. Anti---freeze
CAUTION
WHEN USING ANTI---FREEZE, PUT ON SOME PROTECTION
SUCH AS RUBBER GLOVES.
IF SHOULD DRINK ANTI---FREEZE, THROW UP AT ONCE
AND TAKE MEDICAL ATTENTION.
WHEN ANTI---FREEZE COMES IN CONTACT WITH THE SKIN
OR CLOTHING, WASH IT OFF IMMEDIATELY.
DO NOT MIX DIFFERENT TYPES OF ANTI---FREEZE.
KEEP FIRE AND CHILDREN AWAY FROM ANTI---FREEZE.
BE MINDFUL OF THE ENVIRONMENT AND ECOLOGY.
BEFORE DRAINING ANY FLUIDS, FIND OUT THE CORRECT
WAY OF DISPOSING BY CHECKING WITH LOCAL CODES.
ALSO, OBSERVE THE RELEVANT ENVIRONMENT
PROTECTION REGULATIONS WHEN DISPOSING OF OIL,
FUEL, COOLANT, BRAKE FLUID, FILTERS AND BATTERIES.
If it freezes, coolant can damage the cylinders and radiator. It is
necessary, if the ambient temperature falls below 0 ˚ C (32 ˚ F), to
remove coolant after operating or to add anti---freeze to it.
(1.) There are two types of anti---freeze available; use the
permanent type (PT) for this engine.
(2.) Before adding anti---freeze for the first time, clean the
radiator and engine interior by pouring fresh water, and
draining it a few times.
(3.) The procedure for the mixing of water and anti---freeze
differs according to the make of the anti---freeze and the
ambient temperature. Refer to SAE J1034 standard, more
specifically also to SAE J814c.
(4.) Mix the anti---freeze with water, and then fill into the radiator.
NOTE
When the anti ---freeze is mixed with water, the anti ---freeze
mixing ratio must be less than 50%.

:
At 1,013 hPa (760 mmHg) pressure (atmospheric).
A higher boiling point is obtained by using a radiator pres-
sure cap which permits the development of pressure within the
cooling system.
NOTE
The above data represents industry standards that necessitate a
minimum glycol content in the concentrated anti ---freeze.
