OPERATION
NOTE: Before cleaning any surface, an
inconspicuous area should be cleaned to
test spray pattern and distance for
maximum cleaning results. If painted
surfaces are peeling or chipping, use
extreme caution as pressure washer may
remove the loose paint from the surface.
This Pressure Washer is equipped with
automatic delivery flow cut-off:
When the trigger is released, the dynamic
pressure automatically stops the motor.
When the trigger is pressed, the internal
pressure drop automatically starts the
motor and the spray pressure is restored
with a very slight delay.
