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 10 to 11).
OPERATION
Observe the following precautions when operating the pump.
Keep the motor dry! Do not direct stream from pump
discharge onto the motor!
HAZARDOUS PRESSURE. Do not run the
pump with discharge shutoff, as hose may burst or pump
may be damaged due to high temperatures.
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.
DO NOT run pump dry; to do so may damage the seal.
To avoid internal damage to pump, Do not operate with
water temperature above 175° F.
