2. Mixing ratio of coolant
The freezing temperature of the long life coolant varied depending on the ratio of mixing it with
water.
In this machine, irrespective of the outdoor temperature, the long life coolant is mixed with water
with a mixing ratio of 49% at the time of shipment in order to maintain the rust prevention effect of
the cooling system.
In all areas and throughout the year, keep the mixing ratio of the long life coolant at 49%.
Further, use commercial tap water for mixing.
Minimum outdoor temperature (°C) -35
Mixing ratio (%) 49

3. Coolant Replacement Instructions
1)
Lower the attachment on to the ground, and stop the
engine.
2) Remove the radiator cap (1).
3) Open the drain cock (2) at the bottom of the radiator
and drain the water.
Next, open the drain cock (3) of the cylinder block and
drain the water.
4) Close the drain cocks at the two locations, pour tap
water and cleaning agent (radiator cleaner), and run
the engine for about 10 minutes at slightly higher
speed than low idling.
5) Stop the engine, open the drain cocks at the two
locations, and drain the water.
6) After draining the water completely, pour tap water and
clean until the drained water becomes clean.
7) Close the drain cocks at the two locations, pour the
coolant which is a mixture of tap water and LLC up to
the mouth of the radiator water inlet opening.
8) Run the engine at low idling for about 5 minutes and
stop the engine.
Since the water level decreases because the air inside
gets released, replenish coolant up to the mouth of the
radiator water inlet opening, and close the cap.
9)
Drain the cooling water in the supplementary tank (4),
clean the inside of the tank, and pour the coolant up to
the “FULL” mark.
