BCleaning Transmission Strainer
When changing the transmission fluid, disassemble and
rinse the strainer with nonflammable solvent to completely
clean off filings.
Check O-rings, replace if damaged, cracked or hardened.
When reassembling be careful not to damage the parts.
A Since the fine filings in the oil can damage the
precision component parts of the hydraulic system, the
end of the suction line is provided with an oil strainer.

If it freezes, coolant can damage the cylinders and
radiator. If the ambient temperature falls below 0 (32 F)
or before a long-term storage, let out cooling water
completely, or mix fresh water with long-life coolant and fill
the radiator and reserve tank with the mixture.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again. Repeat
this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in cooling water in the percentage (%) for
a target temperature. When mixing, stir it up well, and
then fill into the radiator.
4. 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.
A When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
