6 -  2  Cooling  water

(X)  W ater  for  cooling

Use  the  mixture  of the good  quality  soft  w ater  like  city  water  and  the  Long  Life  Coolant 

(LLC)  of anti-freeze  and  anti-rust  for  the  aluminum  radiator.

Percentage  of LLC  must  be  30%  to 50%,  Under  the  30%,  the  anti-rust effect  will 

decrease,  and  over  the  50%,  the  anti-freeze  effect  will  decease.

The  following  percentages  are  recommended for each  ambient  temperature;

30%:  - 1 0 1  

40%:  - 2 0 1:

50%:  - 3 0 ‘C

In  case  of replenishment,  use  LLC  of  the  same  brand  and  the  same  density.

Normally  LLC  should  be  replaced  every  2  year.

(2)  Total  quantity  of cooling  water 

Total  cooling w ater  quantity

# 2   Diesel  Fuel

[Note]

If other  kinds  of fuel  is  used  or  fuel  being  used  contains  w ater  or  dust,  it  deteriorates  the 

engine  performance  or leads  to  a  serious  trouble.
