BEFORE STARTING THE UNIT
PRE-OPERATION SAFETY
1. This unit should only be placed on a level surface to ensure proper lubrication for the water pump while operating. Placing the unit on a level surface will also ensure that fuel, oil, and other fluids don’t spill during operation. NEVER spray water directly on the unit.
2. Do not use unit in an area:
a. with insucient ventilation. b. where there is evidence of oil or fuel leaks. c. where flammable gas vapors may be present.
This unit has multiple ignition sources that could cause a fire or explosion.
3. If using a wheel kit, be certain to block the wheels to prevent the unit from moving while operating.
4. Do not allow the unit to be exposed to rain, snow, or freezing temperatures. If any
part of the unit becomes frozen, excessive pressure may build up in the unit which could cause it to burst. This would result in possible serious injury to the operator or bystanders.
5. Pump oil level should be checked before each use. Make certain the oil is on the “Full”
mark on the dipstick or in the center of the oil sight glass. If the level appears to be low, fill with SAE30W non-detergent pump oil.
6. Your pressure washer is equipped with an Electric Starter. On initial start-up, wear
proper eye and skin protection when filling the battery with acid. Fully charge the battery to allow Electric Starter to function.

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
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.

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.

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.
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.
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.
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.

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 ma­chine.
Regardless of the starting method, remember to gradually move the choke lever back to the “open” position once the engine is running.

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.
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.
WARNING
The temperature of the water can become extremely hot during operation.
Use caution when operating the spray gun.
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.
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.

SHUTTING DOWN & STORAGE
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.
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.
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.

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.
