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.; 00=0”, 15=15°,
25=25°, 65=detergent/low pressure.
. The 0” nozzle (REd): This is a blasting nozzle. It delivers a
very concentrated stream of water. Be cautious when using the
straight narrow stream. It is not recommended for use on painted
or wood surfaces, or items attached with adhesive backings.
Uses: Removing weeds from sidewalk cracks, stubborn stains
from concrete, 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 swimming pool bottoms, degreasing engines.
4. The 65° nozzle (BlACK): This is a low pressure detergent
application nozzle. This broad spray pattern distributes solution
over vast areas under low pressure. Uses: Detergent application,
misting or rinsing.
