Cleaning Tips - AR Blue Clean AR620 Maintenance Manual

The gun nozzle supplied with the pressure washer provides optimum
cleaning for universal cleaning applications if used properly.
Cleaning agents are most effective when the surface is rinsed first
to loosen dirt. After pre-rinsing to loosen dirt, then clean with
detergent.
Detergent should be applied from the bottom to the top of the
washing area. Apply detergent and allow the detergent to react
with the dirt, then rinse from the top to the bottom. This detergent
applying and rinsing technique will help to avoid streaks and skips in
the washing area.
Never use more detergent than is necessary to clean the surface.
Always follow directions supplied by the detergent manufacturer on
the container.
For best spraying results, hold the gun 6-12" away from the washing
surface and use long, slow deliberate side to side strokes, similar to
using a paint sprayer. This technique will provide the most effective
cleaning impact and minimize streaks and skips in the cleaning
process. Waving the spray gun aimlessly across the surface wastes
water and expensive detergent and prolongs the cleaning process.
If the pressure washer is used to apply wax, the gun should be held
further from the surface to optimize the "misting" effect when
applying the wax. For best results, follow the directions supplied by
the wax manufacturer.

Hold the gun/wand in the normal operating position. Turn the
nozzle sleeve clockwise for a fan spray and counterclockwise for
a stream. (Pull the nozzle sleeve forward for high pressure while
pushing the sleeve away from the gun for low pressure.) After
shutting down the unit and draining the hose, spray a lubricant,
such as WD40, on the backside of the nozzle and work the nozzle
back and forth from high to low pressure. This will help prevent
the nozzle from sticking. Examine nozzle tip for blockage only with
pressure washer "OFF" and pressure relieved from system.
