QUICK-CONNECT NOZZLES:
Various nozzles may be quick-connected into the end of the dual lance to change
the spray pattern. The detergent nozzle has been pre-installed at the factory.
When using quick-connects (Q.C.), be certain the connection is securely locked
as shown at right. 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 first two digits indicate
the spray fan degree: 00=0°, 15=15°, 25=25°, 40=40°, 65=65°.
. 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 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) :
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 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
aluminum siding, cleaning windows, washing vehicles, spraying sidewalks,
driveways, and patios.
4. The 25° nozzle (GREEN):
a. On standard units, 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 perational problems with the machine.
b. On units equipped with the 300°F Steam Option, this nozzle is
replaced with a steam nozzle assembly.
5. The 65° nozzle : (included in dual lance.)
This is a detergent nozzle. The broad spray pattern distributes solution
over vast areas. Uses: Detergent application, misting or rinsing.
NOZZLE CONNECTION:
. Ensure the trigger gun is locked in the OFF position.
2. Quick-connect nozzles can be connected or disconnected from the dual
lance assembly by retracting the locking ring on the quick-connect fitting.
When connecting the desired nozzle, push the locking ring over the quick
connect nozzle to secure connection.
