Barbecue Grills, Outdoor Power
Equipment & Gardening Tools
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher All Purpose Cleaner or
Degreaser, place detergent suction tube
directly into cleaning solution and apply
detergent at low pressure. Allow Kärcher
detergent to remain on surface 1-3 minutes.
Do not allow detergent to dry on surface.
Rinse at high pressure keeping the spray
nozzle approximately 3-6 inches from the
cleaning surface. For removing extremely
stubborn dirt, it may be necessary to move
the spray nozzle even closer to the surface
for greater dirt cutting action. To remove
caked on mud from garbage cans, lawn
mower blades, wheel barrels or other
non-sensitive metal surfaces, you may
want to experiment with different settings on
the Quattro Nozzle.
Optional cleaning accessories are available to further enhance your cleaning capabilities:

Patio & Lawn Furniture
(with or without detergent)
Pre-rinse furniture and surrounding area
with fresh water. If using Kärcher All
Purpose Cleaner, place detergent suction
tube directly into cleaning solution and apply
to surface at low pressure. Allow Kärcher All
Purpose Cleaner to remain on surface 1-3
minutes. Do not allow detergent to dry on
surface. If needed use special Wash Brush
Attachment to remove stubborn dirt. Rinse
at high pressure in a sweeping motion
keeping the spray nozzle approximately 3-6
inches from the cleaning surface. For best
results, clean from top to bottom and from
left to right.
Recommendations
• Before cleaning any surface an inconspic-
uous area should be cleaned to test spray
pattern and distance for maximum clean-
ing results.
• If painted surfaces are pealing or
chipping, use extreme caution as
pressure washer may remove the loose
paint from the surface.
• While using on surfaces which might
come in contact with food. Flush surfaces
with plenty of drinking water.
