4) Make the numerical value by comparing the test paper which hue has changed with the
color list of label on storage bottle.
5) By comparing the hue changed into yellowish green or so with the green color indication
of test paper storage bottle, confirm the density. (Then, the density indication must be in
the hue range of 33% to 50%).
6) The brown at the middle of test paper and the lower pink color indication represent the
additive state for rust prevention, and the proper range is that the meeting numerical
value of brown (vertical) and pink color (horizontal) locates in the range of 0.3 to 0.8 at
the color list of label on the test paper storage bottle.
7) In case of less than 0.3, replenish the additive for rust prevention (DCA4), and in case of
more than 0.8, pour out the cooling water about 50% and then readjust the density after
refilling with clean fresh water.

2.1.2. Fan belt
•
Use a fan belt of specified dimensions, and replace if damaged, frayed, or deteriorated.
•
Check the fan belt for belt tension.
If belt tension is lower than the specified limit, adjust the tension by relocating the alterna-
tor. (specified deflection: 10 ~ 15 mm when pressed down with thumb)
2.1.3. Engine oil
•
Check oil level with the oil level gauge and replenish if necessary.
•
Check the oil level with the engine cooled. If the engine is warm, allow time for 5 ~ 10
minutes for oil drain into the crankcase before checking oil level. The oil level must be
between Max and Min. lines on the gauge.
•
Engine oil should be changed at the specified intervals. (800 hr) Oil in the oil filter should
be changed simultaneously.
- First oil change : 50 hr operating
•
The oil viscosity grades should be selected SAE NO.15W40 and API CD or CE.
