DUAL LANCE ASSEMBLY WITH ADJUSTABLE PRESSURE
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 dam-
age. 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°,
40=40°, 65=65°.
1. The 0° nozzle (RED): This is a blasting nozzle. It delivers a very con-
centrated 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, alumi-
num 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 win-
dows, washing vehicles, spraying sidewalks, driveways, and patios.
This unit features a dual lance assembly with adjustable pressure which

INSTALLATION & PREPARATION
WATER SUPPLY:
1. Select a water supply hose which is a quality grade of garden hose measuring
at least 3/4" ID and no longer than 50 feet.
2 Check the water inlet strainer to ensure it is clean and free of any obstructions.
As a strainer becomes obstructed, it restricts proper ow of water to the
pump. This can result in cavitations which will prematurely cause failure
of pump packings.
a. Using a screwdriver, remove the screen from the water inlet.
b. Clean or replace if necessary.
3. Connect the hoses.
a. Connect one end of the water supply hose to the water inlet of the unit.
b. Connect the other end of the hose to your pressurized water supply.
NOTE 1: Do not use a non-pressurized water supply (i.e. from a pond or
well) with this unit.
NOTE 2: When connecting the water inlet to the water supply mains, local
regulations of your water company must be observed. In some
areas, the unit must not be connected directly to the public drinking
water supply. This is to ensure there is no feedback of detergents
into the water supply. (Direct connection is permitted if a backow
preventer is installed. Check with local authorities for approval.)
NOTE 3: If there is a high mineral content in your water, it is highly
recommended that a water softener and an additional water strainer
be added to the water inlet to help prevent the possibility
of excessive scale buildup inside the heat exchanger coil. Clean
both strainers before starting your pressure washer.
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
rst two digits indicate the spray fan in degrees, i.e.; 00=0”, 15=15°, 40=40°.
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 backings. 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.
NOZZLE CONNECTION:
1. Be certain the trigger gun is locked in the “OFF” position. See WARNING, left.
2. The nozzle assembly should be disconnected from the gun/wand assembly
at this by retracting the locking ring on the quick-connect tting to remove
the nozzle.

3. Connect the hoses.
a. Connect one end of the water supply hose to the water inlet of the
unit.
b. Connect the other end of the hose to your pressurized water supply.
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 pounds per square
Inch (PSI) and a maximum of 125 PSI. (A typical outdoor faucet will
generally supply this PSI if turned completely “ON”.)
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the pressure washer nameplate. (You can
check GPM by timing how long it takes to fill a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive
pump damage may result if the water temperature exceeds this
acceptable level.
5. Never allow the unit to operate without the incoming water line
attached and the water supply is completely turned on.
NOTICE
• If there is a high mineral content in your water, it is highly recommend-
ed that a water softener and an additional water strainer be added
to the water inlet to help prevent the possibility of excessive scale
buildup inside the heat exchanger coil.
UNLOADER
The unloader has been preset at the factory.
4. 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.

If oil appears dirty or milky, changes may be required in greater
frequency. Use SAE20 or 30 non-detergent pump oil and fill only to
the center of the oil sight glass. DO NOT overfill.
NOZZLE: Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. Nozzles should be
replaced whenever pressure is less than 85% of the maximum. The
frequency of replacement will depend upon such variables as mineral
content in the water and number of hours the nozzle is used.
CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump
oil after the first 50 hours of operation. After initial change, every 3
months or 500 hour intervals are recommended. If oil appears dirty or
milky, changes may be required in greater frequency. Use SAE20 or
30 non-detergent pump oil and fill only to the center of the oil sight
glass. DO NOT overfill.
REPLACE HIGH PRESSURE NOZZLE: Water flow through the spray
nozzle will erode the orifice, making it larger, resulting in a pressure
loss. Nozzles should be replaced whenever pressure is less than 85%
of the maximum. The frequency of replacement will depend upon such
variables as mineral content in the water and number of hours the
nozzle is used.
