QUICK-CONNECT NOZZLES:
Various nozzles may be quick connected into the end of the lance 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 lance, causing severe injury or serious
damage. To determine spray fan, refer to the actual number stamped on the
nozzle. The rst two digits indicate the spray fan in degrees, i.e., 00=0°,
15=15°, 25=25°, 40=40°.
1. The 0° nozzle (RED) (OPTIONAL): 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 backing. Uses: Removing
weeds from sidewalk cracks, stubborn stains from concrete, masonry,
aluminum and steel, caked mud from equipment, and cleaning lawn
mower undersides.
2. The 15° nozzle (YELLOW) (STANDARD): 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).
3. The 25° nozzle (GREEN) (OPTIONAL):
a. This is a ushing nozzle. This pattern is best suited for ushing
dirt, mud, and grime. Uses: Wet sweeping leaves from walk,
curbs and driveways, cleaning stable oors, washing swimming
pool bottoms, degreasing engines.
b. On units with steam option, this nozzle is used for 250°F Wet
Steam operation. This nozzle is sized for operation with the
unloader and steam valve (where applicable) to provide high
pressure wet steam. Replacement of this nozzle with an
improperly sized nozzle may cause operational problems with
the machine.
4. The 40° nozzle (WHITE) (OPTIONAL): 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, washing vehicles, spraying sidewalks, driveways, and patios.
1. Ensure the trigger gun is locked in the OFF position.
2. The quick-connect nozzle should be disconnected from the lance at this
time. As shown below, retract the locking ring on the quick-connect tting
to remove the nozzle.
