Tightening Couplings
To prevent air entry or water leakage, tighten the couplings
thoroughly.
B-3
Strainer
Always fit strainer to end of suction line and hold it with the
tightening band. The strainer should be regularly checked and
cleaned out to insure full liquid flow at all times.
B-4
Starting
The pump is ready for operation after completion of the
procedures outlined. Start pump by starting the engine as
outlined in the Engine Instruction Manual. Open fuel cock, close
engine choke, start engine.
NOTE:
QP pumps are self priming and no additional
priming is required as long as the casing is filled
with water and there are no suction line leaks.
B-5
Shutdown
Operation is stopped by stopping the engine as outlined in the
Engine Instruction Manual. Always operate at no load for 2 or 3
minutes to allow cooling before shutdown. When the pump has
been operating in freezing weather or in pumping liquid
containing considerable amounts of trash and /or foreign matter,
it is advisable to remove both the drain plug and the prime plug
and allow the body to drain. Flush solids out of the pump body.
Replace plugs.
Caution!
1. If flexible hose is laid across a
roadway protect if with
planking. Instantaneous shut
off pressure is applied when a
vehicle runs across an
unprotected hose and will
cause 'hydraulic shock'. This
can damage the pump and/or
the hose.
2. A relief valve should be used to
avoid 'hydraulic shock' if
sudden "shut off" cannot be
avoided.
3. Do not use QP Pumps with
pressure feed e.g. from a fire
hydrant.
