PRESSURE ADJUSTMENTS
The pressure setting is preset at the

these meth ods.

are, the less the pressure will be
on the surface to be cleaned.

nozzle delivers a less powerful
stream of water and a wider spray
pattern.

to increase pump
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
