WARNING
The engine exhaust from this product contains chemicals known to the
State of California to cause cancer, birth defects, or other reproductive harm.
The engine governor is set at the factory. Do not tamper with any part which may increase the governed engine speed.
Power unit preparation-Electric Motors: Make certain the input power to your electric motor is proper, single phase or three phase, and is of the proper voltage according to the motor specification plate. Be sure of the proper motor rotation. Pump impeller should rotate counterclockwise, looking from the suction inlet side. For single phase motors consult the motor manufacturer’s instructions for wiring for counterclockwise rotation. Three phase motor rotation may be reversed by
III. PUMP OPERATING INSTRUCTIONS
When pumping dirty water or other liquids which may contain solids, always use a pump strainer on the end of the suction line specified by the manufacturer. If the suction strainer is likely to clog with dirt and debris, do one of the following: (a) Prepare a bed of rocks on-which to rest
the strainer. (see Figure #3.)
(b) Tie the strainer so that it stays off the
bottom of the pit, excavation, etc.
(c) Tie the strainer inside a basket or pail.
(see Figure #3.)
Drain the pump body whenever there is a danger of freezing. Always use rubber feet under portable pump when operating on a hard surface. This will prevent damage to the pump and power unit. Always flush out the pump at the end of operation if the liquid being pumped may leave a solid or sticky residue in the pump. If this is not done, damage to the pump may result.
CAUTION:
interchanging any two of the three power leads. Make certain that wiring for your electric motor complies with all existing local codes. Power unit preparation-Hydraulic and Pneumatic Motors: Consult the separate instruction sheet supplied with each hydraulic or pneumatic motor powered unit.

For liquids having specific gravities greater than 1.0, increase the rated horse-power (from catalog) by a factor equal to the specific gravity of the liquid being pumped. (Ex. Catalog HP x Specific gravity = Actual HP required)

KEEP PUMP SECURED AND FAR ENOUGH FROM BANK THAT SUCTION HOSE WILL NOT PULL IT INTO THE WATER. TIE PUMP DOWN IF NECESSARY.
CORRECT!
PUMP AND HOSE ARE SUP- PORTED. PUMP IS LEVEL AND A STRAINER IS USED.
SUPPORT HOSE OR PIPING
NOTE; PUMP CAN LIFT WATER FROM A DEPTH OF 25’. HOWEVER IT IS BETTER TO USE THE SHORTEST SUCTION LIFT POSSIBLE INCORRECT AND DANGEROUS! PUMP AND HOSE ARE NOT SUPPORTED, PUMP IS NOT SITTING LEVEL AND NO STRAINER IS USED.
Fill pump with clean liquid and try priming again. Shut off power source to pump. Shut off valves to and from pump. While observing all safety precau- tions for the liquid being pumped, disconnect suction and discharge lines and drain the pump completely. Fill the pump with water. Install a vacuum gauge in the suction port (see figure 4). Turn on power source. Vacuum should exceed 22” of mercury when pump shaft is rotating at 3450 RPM and should equal or exceed 11”of mercury with pump shaft at 1750 RPM. If vacuum is below these values, check the following: a. Leak at suction fitting b. Pump rotation. Impeller should rotate counter- clockwise when viewing through suction end. c. Pump speed. (Maximum vacuum performance drops off rapidly with decreasing RPM). d. Sealing of check valve gasket between body
and volute.
e. Check for worn impeller and or volute. If necessary,
replace these parts. (See items B.5., B.6. & B.7. of section V).
f. Worn shaft seal. If pump suction tests OK, attach suction line and check suction at end of suction line. Failure to get suction here indicates leaking connections, leaking hoses, pipes, or obstructions in the lines. Liners of suction hose will occasionally collapse inside the hose. Check same items as in 1, 2, and 3 above. Replace any worn or broken components; check clearance between impeller vanes and volute face (See section V #B.5.).

DIAGNOSIS TREATMENT A. Does not prime or does not pump B. Pump has insufficient flow
NOTE: Reducing pipe size will drastically reduce pump performance and can damage pump if overly restricted. The suction line should always be the same size or larger than the discharge line. For optimum pump performance the pipe size should remain the same as the port sizes.
Fill the pump body with liquid before starting. Do not run the pump dry; damage to the seal may result. There are no points on the pump which need lubrication. The shaft seal is self lubricating, and designed to handle clean liquids. Make certain that all hose and pipe connections are airtight. IMPORTANT: An
air leak in the suction line may prevent priming, and will reduce the capacity of the pump. Always place the pump as close as possible to the liquid to be pumped. Keep all lines as short and straight as possible. Avoid sharp bends in hoses. Keep the pump on a level foundation. See Figure #1. If flexible hose must be laid across a roadway, protect it with planking. Instantaneous shut-off pressures applied when a vehicle runs across an unprotected hose will cause“hydraulic shock”. This shock can damage the pump and/or damage the hose. See Figure #2.
