Automatic Shutdown
At the completion of an irrigation run the engine will shutdown automatically if the sprinkler control selector
valve on the Gun Cart has been set to shut off the water supply. (See Page 15) Otherwise the engine will run un-
til it is manually stopped.
Maintenance
(
Note.
New engines are shipped
without
oil!!!) Use Type SAE30 Oil
Regularly check the engine oil level. Make periodic oil and air cleaner changes. Read the engine manufacturer's
manual for instructions and maintenance procedures.
Oil Alert
-
Please note the following:
The Honda engines used on the booster pumps are equipped with a low oil level switch. If the engine becomes
low on oil, it will stop. To avoid unwanted shutdown of the pump, it is important that the engine oil level be
kept full.
Note:
The dipsticks on the Honda engines are designed to indicate the proper oil level when the checking plug
is unscrewed. Remove the dipstick, wipe it clean and check the oil level without screwing it back into the en-
gine. Be sure to follow the engine manufacturers recommendations when checking the oil level. Just removing
the plug and checking the level may give a false reading that is higher than actual oil level.
Winterizing
The pump must be drained of water. To drain the pump, remove the plug from the bottom of the pump body.
Service the engine in preparation for the next season.
Booster Pump Operating Instructions
If the automatic shutdown feature is in use or the nozzle becomes plugged and the pres-
sure switch fails to stop the engine, the water inside the pump will become scalding hot.
The booster pump is equipped with a high temperature valve, which discharges a small
quantity of water to prevent the water in the pump from becoming too hot. The valve is
located on the pump volute as indicated in the drawing below. It can also be installed in
place of the drain plug. Do not operate this pump if this valve is not in place or is damaged.
Do not attempt to plug the discharge port of the high temperature valve!
