Nozzle Review
Various nozzles may be quick-connected into the end
of the wand to change the spray pattern or use the
detergent feature. When using Quick Connects (Q.C.),
be certain the connection is securely locked. If not,
the high pressure water may shoot the nozzle from the
wand, causing severe injury or serious damage.
To determine spray fan, refer to the actual number
stamped on the nozzle. The first two digits indicate the
spray fan in degrees, i.e.; 0=0°, 15=15°, 25=25°, 40 =
40°, 65=detergent/low pressure.
The 0° nozzle (RED): This is a blasting nozzle. It deliv-
ers a very concentrated stream of water. Be cautious
when using the straight narrow stream. It is not recom-
mended for use on painted or wood surfaces, or items
attached with adhesive backings. Uses: Removing
weeds from sidewalk cracks, stubborn stains from con-
crete, masonry, aluminum and steel, caked mud from
equipment, and cleaning lawn mower undersides.
The 15° nozzle (YELLOW): This is a chiseling nozzle.
The spray should be directed at a 45° angle to the
surface and used like a scraper to remove paint, grease
and dirt. Uses: Surface preparation (removing mildew
stains and paint chips).
The 25° nozzle (GREEN): This is a flushing nozzle.
This pattern is best suited for flushing dirt, mud, and
grime. Uses: Wet sweeping leaves from walks, curbs
and driveways, cleaning stable floors, washing swim -
ming pool bottoms, degreasing engines.
The 40° nozzle (WHITE): This is a wash nozzle. This
wide spray pattern disperses the water pressure over a
large area and is recommended for moderate washing.
Uses: Washing down aluminum siding, cleaning win-
dows, washing vehicles, spraying sidewalks, driveways
and patios.
The 65° nozzle (BRASS 1/4” NPT): This is a low pres-
sure detergent application nozzle. This broad spray
pattern distributes solution over vast areas under low
pressure. Uses: Detergent application, misting or rins-
ing. Factory Installed.
The Rotoblast nozzle: Rotating nozzles increase your
cleaning power and decrease your cleaning time.
They offer 0° spray impact with 25° coverage. Nozzles
include filter with quick connect and offer heavy-duty
components for long life and reliability. Uses: Sidewalks,
driveways, track vehicles, muddy areas, old peeling
paints and concrete surfaces.
