5. For longer no-load operation
Keep cooling water in the cylinder, and it will be possible to perform no-load operation at idling for about 10 minutes. In this mode of
operation, close the cylinder drain cock. In this operation in cold weather, put anti-freezing solution in the cylinder.
(Refer to P. 17 "CAUTIONS IN COLD WEATHER.)
STORAGE
(1) Set the water discharge valve to “HALF OPEN”, and open the water discharge valve and muffler drain cock. Push the water stop
valve drain button and drain water completely. After water drain, be sure to close each drain cock.
(2) After detaching the water suction pipe, re-start the engine. Run the vacuum pump 2 to 3 seconds. After discharging water in
the vacuum pump, stop the engine again.
(3) Set the fuel cock lever to "CLOSE".
(4) Dispose of drained fuel in overflow bottle. (Refer to the photo of the next page for overflow bottle.)
(5) Attach the suction port cap and cover the pump before storage.
Notes:
1. Incomplete water drain may cause damage due to freezing or corrosion.
2. After using muddy water or sea water, clean the pump with fresh water. Then, never fail to drain remaining water of all the
parts.
3. Keep a storage house off moisture.
4. Check the battery charging level and electrolyte level once a month. Charge the battery during storage. (Refer to P. 16
"HANDLING OF BATTERY AND BATTERY CHARGER".)
5. Perform water discharge operation once a month for 5 to 10 minutes with the throttle set at high speed.
6. For long storage, open the carburetor drain cock and drain fuel in the float chamber. (Refer to P. 13 “Carburetor”.) Use
completely fuel in the fuel tank or replace it within 3 months.
7. Before storage, confirm that water is completely drained. In operation in cold weather, put an antifreeze mixture in the
pump. (Refer to P. 17 "CAUTIONS IN COLD WEATHER".)
