4.3 Low Pressure Operation with Brush

When cleaning surfaces with a grease contamination - typically car
paintwork 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 Washing Brush (No.7c) to the Spray
Gun.
• Leave for 2-4 minutes for the detergent to have maximum effect.
• With or without the pressure washer switched on, brush down the
surface being cleaned, this physical agitation removes all trace of
traffic film.
• Finally revert to the high pressure operation with the Spray Lance
and complete the wash down.
We recommend the following cleaning method:
Step 1:
Remove loose dirt by washing over the surface to be cleaned with the
high pressure jet.
Step 2:
Spray on the detergent and leave for 1-4 minutes, so assisting the easy
removal of fine dirt and associated greasy adhesions.
Step 3:
Finally, spray off the loosened dirt with the high pressure spray.
