noZZle connection:
. Be certain the trigger gun is locked in the "OFF" position. (See WARNING,
right.)
2. Connect the lance assembly to the trigger gun assembly at this time.
Be certain the connection is securely tightened.
installation & preparation
water supply:
. 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 flow 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 backflow 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 (#851-0207) 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.
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 25 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 25°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.

noZZle reView:
. Selection of high pressure can be achieved by turning the protective
collar clockwise as shown in Figure , right. While in the high pressure
mode, water is directed solely through the 5° spray nozzle creating a
concentrated high pressure “fan” spray.
2. Selection of low pressure detergent application can be achieved by
turning the collar counterclockwise as shown in Figure 2, right. Once the
pressure is low enough, the detergent injector on the pressure washer will
draw detergent into the system. As the collar is turned, a water/detergent
mixture exits not only from the spray nozzle, but also around the nozzle.
This creates a “fan/cone” combination spray pattern.
