Replace the anti-corrosive zinc when it has been reduced to less than 1/2 of its original

size.

If there is only a little bit of wear, clean the surface by sanding off any corroded areas.

5. Replace plug.

6. Open the Kingston cock and check water leakage.

Inspection • • every 500 hours.

4.4 Inspection of the Electrical Parts

4.4.1 Inspection of Battery

Check the level of fluid in the battery.

When the amount of fluid nears the lower limit, fill with battery fluid (available in the market)

to the upper limit. If operation continues with insufficient battery fluid, the battery life is

shortened, and the battery may overheat and explode.

Battery fluid tends to evaporate more quickly in the summer, and the fluid level should be

checked earlier than the specified times.

If the engine turns over at a slower than usual rate and refuses to start, recharge the battery.

If the engine still will not start after charging, replace the battery.

Inspection • • daily (before start-up)

4.4.2 Checking the Tension of the V-Belt of the Alternator

When there is not enough tension in the V-belt, the belt will slip making it impossible for the

alternator to generate power.

Additionally, the fresh water pump will not work causing the engine to overheat.

Check the tension of the V-belt in the following manner.

1. Press the V-belt down with your thumb at the middle of the belt to check the tension.

The give in the V-belt should measure about 8 • 10mm at the depression.

2. To adjust the V-belt tension, loosen the set bolt and move the alternator.

3. Replace the belt if it is damaged.

Inspection • • every 500 hours

Replace • • every 2000 hours
