4.1 High Pressure Operation

• Ensure the Spray Lance (No. 6a) or the Dirt Blaster (No. 6b) are attached

securely to the Spray Gun (No. 8).

• 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 ratchet on the Spray Gun and squeeze the trigger.

• Switch on the pressure washer (No. 2)

The pressurised water jet alone is capable of fulfilling 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 with Detergent

• Dilute the detergent in a suitable container to the required concentrati-

on 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. 1) in the Detergent container.

• Remove lance from the spray gun. Note that the Lance and Dirt Bla-

ster are not for use in Low pressure Operation.

• Aim the spray gun towards the object to be cleaned, release the Safe-

ty Locking Device on the Spray Gun and squeeze the trigger to apply
the detergent to the working area.

• Switch on the pressure washer (No. 2)

4.3 Low Pressure Operation with Brush

When cleaning surfaces with a grease contamination - typically car paint-
work that always has a greasy traffic film covering. Follow the
procedure of:
• Washing loose dirt away with the clean water high pressure spray.
• Apply the detergent in low pressure mode by removing the bayonet fit

spray lance and fitting the Wash Brush to the Spray Gun.

• Leave for 2-4 minutes for the detergent to have maximum effect.
