To reduce friction losses to a minimum, inlet (suction)
line should be short and have as few elbows as
possible.

An inlet strainer will prevent suspended debris from
clogging pump.
The internal running surfaces of the pump and seals
require water lubrication for good, consistent operation.
Allowing pump to run dry will severely damage
pump and seals.
Install a pressure gauge in pump inlet line. Keep at
least two pounds per square inch pressure (2 PSI) in
inlet line whenever pump is operating. If this is not
possible, consult customer service representative.
LUBRICATION
It is not necessary to lubricate pump or motor. The
motor is equipped with sealed ball bearings, lubricated
for the life of the bearing. The mechanical shaft seal in
the pump is self-lubricating and requires no
adjustment. Disassemble pump to replace seal (See
“Maintenance”, Pages 7 and 8).
OPERATION
NOTICE: Observe the following precautions when
operating the pump:
1. Keep the motor dry! Do not direct stream from
pump discharge onto the motor!
2.
Hazardous pressure. Do not run the
pump with discharge shutoff, as hose may burst or
pump may be damaged due to high temperatures.
3. Do not use a standard trigger gun with this pump.
Use only trigger guns with an automatic weeping
feature. These are available as accessories and are
provided with three nozzles. The smallest nozzle
restricts the flow, allowing use of a smaller water
source. The two larger nozzles are used if the water
source will supply the pump’s full capacity.
4. Do not run pump dry; to do so may damage the
seal.
5. To avoid internal damage to pump, Do not operate
with water temperature above 175 degrees F.
