4.1 High Pressure Operation
• Switch on the pressure washer (No.4)
• Ensure the Spray Lance with the Pressure Regulator (No.16) is attached
securely to the Spray Gun (No.12) and the nozzle is set to the required
setting (+).
• Aim the lance towards the object to be cleaned making sure the
recommended working distance is used (for reference see Page 11).
Release the Safety Lock Device (No.13) on the Spray Gun and
squeeze the lever.
The pressurised water jet alone is capable of fulfiling most
cleaning tasks around the garden or on building work but
detergent and wash brush are advantageous when cleaning
vehicles or other paint finishes.
4.2 Low Oressure Operation without Brush
• Fill the Detergent Tank (No.11) with the selected detergent,
ensuring it is the correct concentration (See Page 10 or read
recommended dosage on label)
or
Dilute the detergent to the required concentration before filling the
Detergent Tank. (The correct dilution is dependent on the degree of
soiling of surface and is best determined by experience).
• Set the Spray Lance (No.16) to the lowest working pressure setting "–".
• Set the Detergent Dosing Valve (No.10) to the desired dosage.
• Switch on the pressure washer (No.4)
• Aim the nozzle towards the object to be cleaned, release the Safety
Locking Device on the Spray Gun and squeeze the lever to apply the
detergent to the working area.
• To rinse the detergent away increase the nozzle setting towards “+”
setting. (No detergent will be drawn in with high working pressure).
Spray with the required jet spray setting until no trace of detergent
can be found.
