one or two minutes. A suction lift of 20 feet can take 5 minutes running time to pick up a prime. If pumping does not start within this time, shut off the engine, let unit cool down about 5 minutes, refill pump casing and retry. If engine does not start, refer to Engine Manual. If pump does not prime after 2 tries, refer to “Troubleshooting Chart” in this man- ual.
6.Properly fueled and lubricated, the pump/engine unit will run automati- cally without attention to the con- trols. The gasoline engine has a built- in governor and will adjust the speed of the engine automatically depend- ing on the volume of water being delivered.
Even though this unit will operate
with minimal supervision, it should not be left operating by itself. Depending on the application and area unit is operating (high traffic, people in area, etc.) will dictate the necessity of having someone watching over the unit.
Maintenance
To prevent accidental starting always
remove spark plug, or disconnect and ground spark plug wire before attempting to service or remove any compo- nent.
1.If the pump is located in an area sub- ject to freezing temperature, the pump should be drained when not in operation. Also, the pump should be
2.Clean the suction line strainer at reg- ular intervals.
3.If the gas engine is equipped with a spark arrestor screen in the muffler, it should be inspected for wear peri- odically, and replaced when neces- sary.
NOTE: For information pertaining to the engine and engine parts, consult the Engine Manual or contact the nearest authorized service representative or the manufacturer.
4.Periodically check nuts and bolts on engine, mounting frame and pump. Since this is a gas engine pump, vibration levels tend to loosen nuts and bolts faster than normal. Use Loctite (thread sealant) on threads or lockwashers if necessary.

Refer to Figures 1, 2, and 3.
IMPORTANT: Replace seal seat, (Ref. No. 22) and seal head (Ref. No. 23) at the same time to ensure proper mating of mechanical seal components!
1.Unthread fasteners (Ref. No. 16), nuts (Ref. No. 25) and remove casing (Ref. No. 15) and casing seal (Ref. No. 7) from adapter (Ref. No. 3). Unthread fasteners (Ref. Nos. 11 and 19) and remove volute (Ref. No. 20) and volute seal (Ref. No. 6) from adapter.
