GLOSSARY

PSI: Pounds per square inch is a unit of measure for pressure.

GPM: Gallons Per Minute (Flow Rate)

Cleaning Units: GPM x PSI

Vertical: A vertical pressure washer has the pump located underneath the engine.

Horizontal: A horizontal pressure washer has the pump located behind the engine.

Multi-Reg wand/lance: This type of wand/lance is black and has a spray nozzle which is adjustable from a pencil stream (0°) to a wide angle fan spray (60°). The spray can be adjusted by twisting the nozzle clockwise and/or counterclockwise. Also, the high and low pressure settings can be controlled by moving the nozzle in and out. See page 11.

Hi-Low:This type of lance has one chrome tube with a black knob on the nozzle end. The knob can be turned clockwise and counterclockwise to control the high and low pressure settings. It comes with a ¼” NPT, 15° nozzle. To obtain different spray pat- terns, the nozzle must be removed and replaced with one of the desired degree. The available patterns are 0°, 25°, and 40°. When replacing nozzles, be sure to use one of the same flow rating. Be sure to apply teflon tape to nozzle threads to prevent leaks. See page 11.

Dual Lance: This type of lance has two chrome tubes with a handle grip near the gun/lance connec- tion and two nozzles on the end. The handle grip can be turned clockwise and counter clockwise to control the high and low pressure settings. It also comes with a ¼” NPT, 15° high pressure nozzle. To obtain different spray patterns, the nozzle must be removed and replace with one of the desired degree. The available patterns are 0°, 25°, and 40°. NOTE: Be sure not to remove the chemical nozzle. It is the nozzle with the larger hole in it. When replacing nozzles, be sure to use one of the same flow rating. Be sure to apply teflon tape to nozzle threads to prevent leaks. See page 11.

Quick Connect: This type of lance is equipped with a female quick connect coupler on the end. This allows the user to quickly change out high-pressure nozzles for different spray patterns and change to the soap nozzle for low pressure and chemical/soap applications. See page 12 .

By Pass Mode: During normal operation, a continu- ous flow of cold water is needed to keep the pres- sure washer pump operating at a safe temperature. If the pressure washer is operated without an adequate water supply, or operated for more than two (2) minutes without pulling the trigger, the pump will overheat and cause serious damage. Any damage to the pump due to these causes will not be covered under warranty.
