GLOSSARY OF TERMS
AUTO START/STOP
– Unit will automatically start when the trigger is pulled, and it will stop
the motor on time delay after the trigger has been released in order to prevent the pump from
bypassing and overheating.
PSI
– Pounds per square inch. Pressure washers are designed and rated to operate at a specific
PSI. Operating at pressures exceeding the maximum rating could result in damage to the unit
and/or SEVERE PERSONAL INJURY.
GPM
– Gallons per minute. The orifice on the pressure wand assembly has been selected to
deliver up to the maximum GPM for your machine.
PRESSURE WAND ASSEMBLY
– This refers to the gun, wand, and nozzle.
PUMP
– The pump moves the water through the system and delivers it to the pressure wand
assembly.
UNLOADER VALVE
– Is a valve located at the head of the pump for unloading water back
into the bypass when the trigger gun is shut off. It also reduces the load on pump when gun is
off.

SAE 30 W Non Detergent (for GP Pumps) or Hydraulic 68 (for EK Pumps) in the pump.
BACK FLOW PREVENTER

MAXIMUM WORKING PRESSURE -

valve which prevents over pressurization of the high pressure system. It is an important safety
device and must not be tampered with in any way.
PRESSURE SWITCH -
A pressure switch is used to control the motor for the auto stop/start
feature (see diagram).
FLOW SWITCH
– A flow switch is installed on the outlet of the high pressure pump and will
shut off the pump and motor in the absence of water flow as well as turning it back on when flow
is detected
(by squeezing the trigger).
