2.6 Place the pump on level, firm foundation, putting it 

as near as possible to the level of the liquid which is 

to be pumped, but never higher than 25 feet (7.5 me-

ters). Keep all lines straight and as short as possible. 

Avoid sharp bends.

3. Operating Instructions

3.1 STARTING – See Engine Manual
3.2 PRIMING TIME – with a suction lift from 5 to 10 

feet (1.5 to 3 meters)*, the pump should discharge 

liquid in less than a minute; a suction lift of 25 

feet (7.6 meters)*, requires less than 2 minutes. To 

further reduce priming time the engine speed may 

be increased, after the engine is properly broken in. 

If pumping does not start within this time, shut off 

engine and check to find the difficulty (see Trouble-

shooting).

3.3 CONTROL – On high suction lifts, a higher engine 

speed is necessary. On shallow lifts or when there is 

but a little liquid to pump, save fuel and engine life 

by reducing the engine speed. (See Engine Manual)

3.4 CHECK VALVE – If discharge line runs vertically 

more than 30 feet (9 meters), it is advisable to install 

a check valve in the discharge line near the pump to 

stop destructive water hammer when pump is shut 

down. If this is done, it may be necessary to vent the 

top of the pump so that air can be expelled during 

automatic re-priming. This air bleed may be accom-

plished by providing a ¼" (.5 cm) line from the top 

of the pump back to the liquid source. We will not 

assume any responsibility for damage to the pump if 

no check valve is used in the discharge line. Properly 

fueled and lubricated, your pump will run without 

attention.

3.5 If flexible hose must be laid across a roadway, protect 

it with planking. Instantaneous shutoff pressure ap-

plied when a vehicle runs over an unprotected hose 

will cause “hydraulic shock”, which may damage the 

casing or seals.

3.6 Drain the pump body whenever there is danger of 

freezing.

3.7 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.
