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 backow
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

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.

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.

INSTALLATION & PREPARATION
UNLOADER:
The unloader has been preset at the factory.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1. Check the oil level in the pump.
2. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply" pg. 15.
3. Check all hose connections to ensure they are securely tightened.
4. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See "Risk of Explosion or Fire" warnings, pgs.
4-5. Be sure that all damaged parts are replaced and that the mechanical
problems are corrected prior to operation of the unit. If you require service,
contact Customer Service.
5. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is
found, DO NOT USE HOSE! Replace hose before starting unit. See "Risk
of Injection" warnings, pg. 6. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of the
unit. If you require service, contact Customer Service.
