QUICK-CONNECT NOZZLE REVIEW
HOW TO USE SPRAY TIPS
The quick–connect on the nozzle extension allows you to switch between five dierent
quick-connect spray tips. Spray tips can be changed while the pressure washer is
running once the spray gun trigger safety lock is engaged. The spray tips vary the spray
pattern as shown above.
FOLLOW THESE INSTRUCTIONS TO CHANGE SPRAY TIPS:
1. Pull back collar on quick–connect coupler and pull the current spray tip o. Store the
spray tips in the holder provided on the handle. Storing nozzles in the designated
holder will help prevent any debris from clogging the tip.
2. Select the desired spray tip:
• For a gentle rinse, select the white 40° spray tip.
• For light cleaning, select the green 25° spray tip.
• For high pressure cleaning, select the yellow 15° spray tip.
• To scour the surface, select the red 0° spray tip.
• To apply detergent, select the black spray tip. No other spray tip will draw soap.
3. Pull back on collar, insert spray tip and release collar. Tug on spray tip to ensure it is
securely in place.
USAGE TIPS
• For most eective cleaning, keep spray tip 8 to 24 inches away from cleaning surface.
• If the spray tip gets too close to the surface being cleaned, especially using a high
pressure spray tip (red or yellow), it may be damaged. Do not use the red spray tip on
glass. Doing so could result in broken or cracked glass.

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.

CONNECTING TO WATER SUPPLY
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 the flow of water to the pump. This can result
in cavitations which will prematurely cause failure of pump components.
a. Using a screwdriver, remove the screen from the water inlet.
b. Clean or replace if necessary.
3. Connect the garden hose to the inlet of your high pressure pump. Thread the
connection together by hand until tight. Ensure the connection is tight at both ends
(at the pump inlet and at the water supply source).
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 (Gallons Per Minute) 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).
5. Never allow the unit to operate without the incoming water line attached and the
water supply opened all the way.
NOTICE
• 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. This will help
prevent the possibility of excessive scale buildup inside the heat exchanger coil.
Pumps are water cooled. When the machine is running, ensure the trigger of the gun is
pressed to allow a constant flow of fresh water into and out of the pump. Do not let the
machine run for more than 30 seconds without pressing down on the trigger.
triplex pump
Most pumps are protected by a thermal valve. The thermal valve releases water if a
pump starts to run too hot. It will prevent catastrophic heat failure. However, the pump
may have suered damage and need maintenance, repair, or replacement. If it does not
reset and continues to leak water, the thermal valve may need to be replaced.

INITIAL START-UP & OPERATION
START-UP AND OPERATION (COLD WATER)
To start your pressure washer for the first time, follow these instructions step-by-step.
This starting information also applies if you have let the pressure washer sit idle for at
least a day.
1. Make sure the unit is level and placed on solid ground. Ensure the wheels are locked so
that it doesn’t move during operation.
2. Connect garden hose to water inlet on pressure washer pump. To do this, thread the
end of the hose into the inlet by hand until tight and secure.
3.Attach wand extension to spray gun. Tighten by hand.
4. Choose desired spray tip, pull back nozzle extension collar, insert spray tip and release
collar. Tug on spray tip to make sure it is securely in place. See Spray Tips on page 9
for more information.
NOTICE
DO NOT run the pump without the water supply connected and turned on. Failure
to follow this rule will result in damage to the pump. Damage caused by running the
pump without water is not covered by warranty.
5. Pull down on the collar of the quick-connect coupler, slide onto the gun connector
and let go of collar. Pull on hose to ensure the connection is tight.

6. Attach the other end of the high pressure hose to high pressure outlet (“A” on
diagram below) on pump. Pull down on collar of quick-connect, slide onto pump and
let go of collar. Note that some pumps require the hose to be threaded on. Tug on the
hose to ensure connection is secure.
7. Turn water supply on if you have not already done so. Point the gun in a safe direction
and squeeze the trigger to purge the pump of air and debris. Do this until water flow
is no longer erratic. Continue to hold trigger of gun down while starting the machine
to ensure there is no pressure build-up.
8. Take a final look at all connections to make sure there are no leaks or loose
connections. If there are any leaks in hoses, they must be replaced.
IMPORTANT: DO NOT siphon standing water for the water supply.

10. To start the machine, locate the electric ignition switch on the right side of the
engine. Insert the key and turn it to the “ON” position” until the unit starts. Do not
hold the switch to the “ON” position for more than 5 seconds as this can cause
damage to the engine. Check to ensure fuel valve is in the ON position and if starting
cold, move the choke lever to the “CLOSED” position. Reference the component
diagram below for the location of these parts.
11. If desired, the unit can also be started via the recoil starter. Ensure the fuel valve is
open and the choke is applied. Then, pull on the cord until resistance is felt, and then
pull the cord briskly. Return the cord to the engine by hand. Do not let it snap back
against the machine. Once the unit is running, it is now operating as a cold water ma-
chine.
Regardless of the starting method, remember to gradually move the choke lever back
to the “open” position once the engine is running.
*Engine Uses SAE 10W30 Oil

13
HOT WATER OPERATION
& DETERGENT
Now that the unit is running, it is operating as a cold water pressure washer.
When you wish to switch to hot water, turn the burner switch to the “ON” position.
WARNING
The temperature of the water can become extremely hot during operation.
Use caution when operating the spray gun.
NOTICE
Upon initial start-up, water will begin heating up in approximately 20 seconds. It
will reach maximum temperature within 2-1/2 minutes providing that the trigger is
continuously pressed down. The burner will not fire when the trigger is released.
1. Prepare detergent solution according to label directions. Never pump acids, alkaline,
abrasive fluids or solvents through the unit. Due to the unknown and often corrosive
characteristics of many detergents commonly used in the pressure washer cleaning
industry, it is recommended to use only mild detergents with this unit.
2. Fully immerse the detergent strainer into the detergent solution.
3. To apply solution, install the black soaper nozzle to the tip of the spray gun, unlock
the gun, and squeeze the trigger. After a few moments, a detergent/water mixture
will exit the nozzle. Start spraying the lower portion of the surface being cleaned and
move up, using long overlapping strokes. Applying from the bottom up helps avoid
streaking. Allow everything to soak briefly.
Avoid working on hot surfaces or in direct sunlight to minimize the chances of the
detergent drying, which may result in damaged surfaces. Be certain to rinse a small
section at a time.
4. To rinse, lock the trigger gun in the “OFF” position. From here, securely place the
white or green spray tip in the end of the spray gun. Unlock the trigger and spray.
It will take about 30 seconds to purge all detergent from the line. For best rinsing
results, start at the top and work down.
5. Siphon a gallon of water through the low pressure detergent injection system after
each use. This prevents the possibility of corrosion or detergent residue causing
mechanical problems during the next use.
APPLYING DETERGENT
NOTICE
This feature is designed for use with mild detergents only. Since the cleaning solution travels through
the heat exchanger coil, DO NOT use corrosives as they will cause extensive damage as well as pose a
considerable safety hazard.

14
CAUTION
Be certain the hoses and spray gun are not attached to the pump during application
of pump saver or use of the blowout tool. Having a hose attached greatly reduces the
amount of water/debris removed from the pump and coil.
SHUTTING THE UNIT DOWN
1. Move the burner switch to the “OFF” position.
2. Squeeze the trigger and discharge the water for three minutes to cool the heat
exchanger and high pressure hose. Insucient cool-down periods for the high
pressure hose will cause excessive wear and eventual rupture of the hose.
3. Do not close the choke to stop the engine. Backfire or engine damage may occur.
4. Move the engine key switch to the OFF position.
5. Turn o the water supply and pull the trigger of the gun to relieve trapped pressure.
Disconnect and drain the high pressure hose, gun, and lance. Wipe the unit clean and
store in a non-freezing environment.
SHUTTING DOWN & STORAGE
STORAGE & WINTERIZING
When storing the unit for winter, it is important to ensure it is stored in the right
environment. Ensure the storage area stays above freezing during cold weather, and try
to limit the amount of dust gathered on the unit via a cover.
You will need to ensure that the fuel is drained from the engine prior to storage. For the
steps required to do this, see the engine user manual.
Once the unit has been stored and the gasoline has been drained, the last thing to do is
to winterize your pump. This can be done in one of two ways:
• “Pump Saver” Solution (P/N: 85.490.046). This is an anti-freeze solution that is used
before storing the unit. It coats to inside of the pump to ensure that any residual
water doesn’t freeze. To use BE Pump Saver, follow the instructions written on
the bottle. Water freezing in the pump will damage seals and other internal parts.
Freezing damage is not covered by warranty.
• “Pump & Coil Blowout Tool” (P/N: 59.400.000). This tool utilizes compressed air to
forcefully remove any water left in the pump. One end of the tool attaches to an air
compressor, while the other attaches to the inlet of your water pump via an adapter.
Follow the instructions on the back of the packaging to use the Pump and Coil
Blowout Tool.

MAINTENANCE
SPECIFIC MAINTENANCE
ENGINE: The engine instructions that accompany your unit detail specific procedures
for maintenance of the engine. Following the engine manufacturer’s recommendations
will extend the engine’s life and ensure the best possible performance.
PUMP: Change the pump oil after the first 50 hours of operation. After the initial change,
every 3 months or 250 hour intervals are recommended. If oil appears dirty or milky,
changes may be required in greater frequency. Use SAE 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 over time, making it
larger. This will result in a reduction of pressure. 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. Every 3-6 months tends to be a standard interval for replacement.
BURNER AIR ADJUSTMENT: The air shutter has been factory preset for proper
operation between sea level and 2000 feet elevation at standard conditions (60°F
ambient water and air temperatures). In colder temperatures or higher altitudes, it
may be necessary to adjust the air supply to the combustion chamber. This adjustment
will maximize burner eciency and avoid inecient operation or excessive sooting
of the heat exchanger coil. A smoke spot test is recommended during any air shutter
and band adjustment. If you do not have the equipment to perform a smoke spot test,
follow the procedures listed below.
1. The machine must be running and the burner ON.
2. Loosen the Locking Screw (#3 at left) on the shutter.
3. Check for smoke from the heat exchanger exhaust. If smoke is not present, slowly
close the Air Shutter (#1 at left) by moving the dial counterclockwise to a lower
number. Continue moving the dial until smoke appears.
4. Record this setting.
5. Open Air Shutter (#1 at left) two increments. Example: If Air Shutter was set at 2,
move it to 4.
6. Slowly trigger the gun on and o. This will cause the burner to turn on and o. Look
for a smoke pu when the burner ignites.
7. Repeat steps 5 and 6 until you see a pu of smoke. Record the Air Shutter Setting.
8. The dierence between the recorded settings in steps 4 and 7 is the combustion
window. Set the dial 1/2 way between these settings.
