Your new pump is a rugged, well-tested tool, but it requires some routine care and maintenance. Please read this
manual before operation.
WARRANTY

Pump Operation
1. Important: Fill crankcase with oil (There is no oil in the crankcase when you receive the pump).
Approx. 1.5 quarts/1.4 liters (verify oil level with the oil dipstick)
• Summer: use SAE 30 Oil.
• Winter (under 40
o
F or 4oC): use SAE 5W-20 Oil.
2. Fill gas tank. Briggs & Stratton recommends using a lead-free gasoline (minimum of 85 octane). Allow
1/4" or 6 mm of tank space for fuel expansion.
3. To Start Engine
A. Open fuel line valve. Turn fuel line valve to "ON" position. It is located above the throttle control.
B. Move throttle control to "FAST" position. The throttle control is located on the side of the engine. Move
the throttle lever to the full right position.
C. Grasp rope handle and pull slowly until resistance is felt. Then pull cord rapidly to overcome compression,
prevent kickback and start engine. Repeat if necessary.
D. After engine is warmed up, adjust throttle as needed FAST or SLOW.
NOTE: Minor adjustments to the carburetor and governor may be necessary to get pump running to specs.
Please refer to Briggs & Stratton engine Owner's Manual which was enclosed with this document.
4. Place pump in water and start for fastest prime.
A. Pump may fail to prime properly if started in fast idle position on shore first.
5. To Stop Engine
A. Move throttle control to "SLOW" position (throttle lever to full left position)
Operating Notes:
• Do not submerse the muffler in water. May cause damage to the engine.
• Use a 3" dia. discharge hose. Chief pumps are low pressure/high volume. Anything less than 3" dia. will
restrict flow and reduce GPM output.

placed in water.
f. If pump does not prime while starting on shore, place pump
in water prior to starting engine.
g. Check engine speed. Throttle should be fully open. Engine
speed should be 3600 rpm at no load.
a. Check spark plug wire.
b. Check gas level and fuel line valve is open.
Too much oil or grey colored oil:
Pump no longer achieves manufactureres
performance spec.s
