NOTE: The best angle for spraying water against a cleaning
surface is 45°. Spraying head on tends to cause dirt particles
to embed in the surface. When working on vertical surfaces,
it is best to apply detergent starting at the bottom and
working upwards which will prevent the detergent from
sliding down and causingstreaks.
2. To stop the power cleaner, release thetrigger.
NOTE: Excessive pump pressure may be the result of a
clogged nozzle or brass coupling. Always turn off the power
cleaner and remove the battery before attempting to
unclog a nozzle or brasscoupler.
