 Only use mild, environmentally friendly detergents intended for use
with pressure washers. Never use aggressive chemicals (like bleach),
abrasive detergents, or similar to avoid damage to your health, the
product, and the environment.
6.4 PRESSURE REGULATOR
The pressure is preset from the factory to optimize cleaning power and efciency. If
you need a lower pressure output you can:
 Stand further from the surface to be cleaned;
 Use a wider spray nozzle;
 Use the pressure regulator to further lower the pressure (BW3500 and
BW4400 only). Turn the regulator counter-clockwise to lower to the
desired pressure. To raise the pressure back to the factory setting turn
the pressure regulator clockwise until it stops.
