8.3 OPERATOR CONTROLS
The vertical (up/down) angle of the spray can be manually adjusted at the spray head,
using the black knob to tighten the spray head in the required position.
The oscillation controls are located on the side of the oscillation unit, comprising an
Off/On switch and “stroke” selector.
The former Stops/Starts the oscillation action.
The latter determines the length/ angle of the stroke and thus the extent of the spray
area – either a Long (L), Medium (M) or Short (S) stroke.
In addition, a valve is provided where the oscillation water supply is connected to the
HP pressure washer outlet which allows the water supply to the oscillation unit to be
turned on and off.
Adjustments should only be made to the oscillation unit and/or spray angle with
the water isolated and/or engine of the washer stopped
.
Refer to the 500D operators manual for details of the pressure washer itself.
