HOW TO USE NOZZLES
The quick–connect on the nozzle lance allows you to switch
between different nozzles. Nozzles can be changed while power
washer is running once spray gun trigger is locked in the safety
position. The nozzles vary the pressure and spray pattern.
For most effective cleaning, keep nozzle from 8 to 24 inches (20
to 61 cm) away from cleaning surface.
• If you get nozzle too close, especially using a high pressure
nozzle (RED), you may damage surface being cleaned.
The high pressure stream of water that this equipment
produces can cut through skin and its underlying
tissues, leading to serious injury and possible

• NEVER exchange nozzles without the trigger lock being engaged on
the spray gun.
• DO NOT twist nozzles while spraying.
