4.1 High Pressure Operation
• Switch on the pressure washer (No.13)
• Ensure the Spray Lance with the Pressure Regulator (No.4) is attached
securely to the Spray Gun (No.3) 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 9).
Release the Safety Lock Device (No.2) 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 Pressure Operation without Brush
• Dilute the detergent in a suitable container to the required concentra-
tion before using. (The correct dilution is dependent on the degree of
soiling of surface and is best determined by experience).
• Hang the Detergent Suction Tube (No.7) in the Detergent container.
Always ensure the Spray Gun is closed before changing the nozzle setting
• Set the nozzle to the lowest working pressure setting (-).
• Switch on the pressure washer (No.13)
• 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, close the Spray Gun, increase the
nozzle setting towards “+” setting. No detergent can be drawn in
with a high working pressure. Spray with the required jet spray
setting until no trace of detergent can be found.
