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°.
1. 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 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.
b. On units with 250°F 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.
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:
1. 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.
WATER SUPPLY:
PRESSURIZED SUPPLY:
1. Select a water supply hose which is a quality grade of garden hose measuring
at least ¾" ID and no longer than 50 feet.
2. Ensure the water strainer is clean and free of obstructions. Check float
tank for any foreign objects or debris. If water flow becomes restricted to
the pump, cavitation can occur which will cause premature failure of the
pump packings.
