INSTALLATION INSTRUCTIONS

Getting Started
IMPORTANT : Proper initial installation of the equipment will assure more satisfactory performance, longer service life, and lower maintenance cost.
IMPORTANT : The use of a backflow preventer on the water supply hose is recommended and may be required by local code.
The pressure washer should be run on a level surface and in a protected area where it is not readily influenced by outside forces such as strong winds, freezing temperatures, rain, etc. The pressure washer should be located to assure easy access for filling of fluids, adjustments, and maintenance. Normal precautions should be taken by the operator to prevent moisture from reaching the pressure washer. It is recommended that a partition be made between the wash area and the pressure washer to prevent direct spray from the wand from coming in contact with the pressure washer. Moisture reaching the equipment will reduce the pressure washer’s service life. All installations must comply with the local codes covering such installations.
Venting
DANGER: DO NOT run the machine indoors or in an enclosed area, as exhaust fumes may be hazardous to your health.
DANGER: DO NOT operate the machine in areas where flammable vapors (gasoline, solvents, etc.) may be present, as this machine may ignite the vapors.
CAUTION : All venting must be in accordance with applicable federal and state laws, and local ordinances. Consult local heating contractors.
If the pressure washer is to be used in an enclosed area, a flue must be installed to vent the burner and engine exhaust to the outside atmosphere. Be sure the flue is the same size as the burner exhaust vent on the pressure washer. See Figure 1 for location. Poor draft will cause the pressure washer to soot and not operate properly. When selecting the location for installation, beware of poorly ventilated locations or areas where exhaust fans may cause an insufficient supply of oxygen. Proper combustion can only be obtained when there is a sufficient supply of oxygen available for the amount of fuel being
burned. If it is necessary to install the machine in a poorly ventilated area, outside fresh air may have to be piped to the burner and a fan installed to bring sufficient air into the machine. Locate the pressure washer so that the flue will be as straight as possible and protrude through the roof at a proper height and location to provide an adequate draft. This oil-fired pressure washer must have a draft regulator installed in the flue (available from most heating contractors). A draft regulator will permit the proper upward flow of exhaust flue gases.
In addition, the pressure washer should never be operated in an enclosed area where high ambient temperatures exist. High ambient temperatures (above 100° F) can cause engine oil failure and will greatly reduce the engine’s performance.

Gasoline Engine
The gasoline engine is preset for operation at altitudes below 1000 feet above sea level. If operated at higher altitudes, it may be necessary to install a high-altitude main jet in the carburetor. Contact an authorized engine sales and service center for details.
Pre-Operation Check

• Pump Oil (SAE 30W non-detergent oil)
• Cold Water Supply (3.5 GPM • 5/8″ • 20 psi)
• Hose, wand, nozzles (nozzle size per serial plate)
• Water filter (intact, nonrestrictive)
• Engine fuel (unleaded 86 or higher)
• Engine oil (SAE 10W40)
• Burner fuel (No. 1 or No.2 home heating fuel or diesel)

Wayne Oil Burner
Burner Air Adjustment:
The oil burner on this machine is preset for operation at altitudes below 500 feet. If operated at higher altitudes, it may be necessary to adjust the air band for a #1 or #2 smoke spot on the Bacharach scale.
To adjust, start the machine and turn the burner ON. Loosen two locking screws found on the air band and close the air band until black smoke appears from the burner exhaust vent. Note the air band position. Next, slowly open the air band until white smoke just starts to appear. Turn the air band halfway back to the previously noted position. Tighten locking screws.

• For higher altitudes, the air band opening may need to be increased; for lower altitudes, the .air band may need to be decreased.
• For higher humidity, the air band opening may need to be increased; for lower relative humidity, the .air band may need to be decreased.
• For higher ambient temperatures the air band opening may need to be increased; for lower ambient temperatures, the air band opening may need to be decreased.
• Adjust to your operating location’s environment as needed for the best smoke spot and performance compliant with local, state, and federal regulations.

Fuel Pressure Adjustment:
To adjust fuel pressure, First, install a pressure gauge into the port just after the pump fuel exit. Turn the adjusting screw (located at the regulator port) clockwise to increase, and counterclockwise to decrease.
Do not exceed 205 psi or lower the pressure below 130 PSI, when checked at the post-pump pressure port.
The fuel pressure may need to be adjusted due to altitude. For every 500 ft altitude above sea level, the boiling point of water goes down 1 °F. At high altitude environments, this boiling point change may require the heat input to be lowered so the water input does not turn to steam earlier than at the factory settings and activate the pressure sensors and pressure relief equipment when the unit is operated and much higher altitudes from factory settings or local dealer site settings. Check with your dealer before making local site fuel pressure adjustments.
Also, as ambient temperature changes seasonally, the fuel temperature in the feed tank and air temperature inlet can impact fuel flow. In more extreme temperatures, this local site adjustment may also require different fuel nozzles for fuel inlet temperatures that are at seasonal extremes (higher or lower) in locations where the temperature changes are beyond moderate temperatures of between 40°F and 90°F. Colder temperatures will make for a thicker flow and less fine fuel spray while hotter temperatures will make for a thinner flow and a more fine spray with the same nozzle. Consider alternate nozzle configurations from the baseline factory-supplied nozzle for operating in such temperature extremes if performance is not meeting needs with air band and fuel pressure settings alone.
NOTE : When changing the fuel pump, a by-pass plug must be installed in the return line port or the fuel pump will not prime.

OPERATION INSTRUCTIONS

Before Starting

1. Read all manuals provided with this pressure washer.
   Become familiar with the location and function of all operating and safety controls.
   WARNING : Check hoses, fittings, wand, trigger gun, and fuel connections daily for signs of wear, cracks, and looseness, and replace as required.

2. Connect the water supply hose to the garden hose connector located on the pump.
   The water faucet and supply hose must be capable of providing a minimum of 3.5 gallons per minute (GPM).

3. Fill the oil burner fuel tank. Use kerosene, #1 grade home heating oil, and #1 or #2 diesel fuel. DO NOT USE GASOLINE, CRANKCASE OIL DRAININGS, OR WASTE OIL.
   WARNING : DO NOT fill the engine fuel tank while the engine is running or hot. Let the engine cool before refueling or spontaneous fire may result. Fuel spillage or vapors could ignite if the engine is hot.

4. Fill the engine fuel tank. Do not overfill, fill to the bottom of the filler neck only. Use lead-free gasoline minimum 86 octane. DO NOT use gasoline containing more than 15% MTBE, 5% methanol, or 10% ethanol. Refer to the provided gasoline engine manual for additional details.

5. Check pump and engine oil levels.

6. If detergents are to be used, only use detergents intended for pressure washers. Follow the instructions on the detergent container.
   IMPORTANT : Before installing the pressure nozzle on initial start-up, turn on the water supply and allow water to run from the end of the wand until clear to prevent the pressure nozzle from clogging.
   IMPORTANT : If the pressure washer has not been used for an extended period of time, remove the pressure nozzle from the end of the wand and turn on the water supply. Allow water to run from the end of the wand until clear.

7.  Install the proper pressure nozzle for your cleaning needs on the end of the wand, refer to Figure 4.

IMPORTANT : The trigger gun provided with this pressure washer is equipped with a manual trigger lock to prevent accidental operation of the trigger gun. (Refer to Figure 4) The manual trigger lock should be used whenever the trigger gun is not in use.
To Start
DANGER : DO NOT point a wand or trigger gun at your- self or at any person. Bodily injury may result from water under high pressure.
WARNING : Wear eye, ear, hand, foot, and skin pro- tection at all times while operating the pressure washer.
IMPORTANT : The water must be turned on before starting. Running the pump dry will cause damage and void the warranty.
IMPORTANT : DO NOT allow the machine to run with the trigger of the trigger gun released for more than 10 minutes at any one time or damage to the pump may occur.

1. Turn ON the water supply.

2. Hold the wand firmly, and release the trigger of the trigger gun.

3. Place the engine ON/OFF switch in the ON position.

4. Open the fuel shutoff valve (if so equipped). Move the choke lever to the FULL CHOKE position, (a choke may not be needed on a warm engine). Move the throttle lever to the HALF THROTTLE position.

5. Pull the rope starter slowly until resistance is felt, then pull briskly. Do not allow the rope starter to snap back against the engine. Return it gently to prevent damage to the starter.

6. When the engine starts, move the choke lever until the engine runs smoothly. When the engine warms, move the choke lever to the NO CHOKE position. Move throttle the lever to the FULL THROTTLE position.
   IMPORTANT : To allow for proper burner operation, the throttle control must be kept in the full throttle position during operation.
   NOTE : If the engine fails to start, refer to the Troubleshooting Guide in this manual.

7. Squeeze the trigger of the trigger gun and allow air to purge from the system.

8. If HOT water is desired, adjust the thermostat to the proper temperature and turn the burner switch ON. The burner will light immediately with a small puff of smoke.
   You may need to initially adjust your burner for peak performance. See the Oil Burner section under Installation. If the smoke continues, contact Customer Service at 1-303-792-5200. When the trigger of the trigger gun is released or when the thermostat temperature setting is reached, the burner will automatically turn off.

To Clean
DANGER: DO NOT place hands or fingers in front of the high-pressure spray. Bodily injury may result.
The detergent injector valve operates by reducing the volume of water, thus a vacuum is achieved and detergent is drawn into the system. DO NOT reduce the water inlet flow so the pump cavitates due to water starvation.
Operating a pump with insufficient water will damage the pump seals.

1. Insert the detergent inlet line into a container of mixed detergent.

2. Completely open the detergent control knob located on the side of the detergent injector valve. Refer to Figure 5.

3. Start the detergent suction by rotating the water adjustment knob of the detergent injector valve.
   Refer to Figure 6. Turning the knob counterclockwise will pull detergent into the system. The flow may be observed through the clear detergent line. Secure the knob position with the knurled nut.

4. The side detergent control knob can now be adjusted to meter the desired amount of detergent.

5. Wash from the bottom to the top, using side-to-side motions. This washes away heavy dirt and allows the detergent to soak as you work toward the top.

6. Do not wash at a 90° angle to the work (straight at it). This will allow water to splash back at you and reduces your cleaning power. Wash at a 30° to 60° angle to the work. This will allow the water to splash away from you and the water will wash the dirt away faster and easier.

7. Use the width of the spray pattern to wash in a wide path. Overlap spray paths for complete coverage washing from side to side, using slow, steady
   motions.

8. The nozzle should be 12″ to 24″ from work, closer to tough areas. Be careful on painted or delicate surfaces, the pressure may damage the surface if nozzle is too close.

9. Small parts should be washed in a basket so the pressure does not push them away. Larger, lightweight parts should be clamped down so the pressure does not push them away.

10. Turn the side detergent control knob clockwise (CW) for detergent decrease. Wait for the detergent to clear always rinse with cold water after using the detergent. Rinse from the top to the bottom to prevent detergent from dripping onto a rinsed area. For the best results contact your Hotsy dealer to help you select the best detergent for your application.

To Stop

1. If detergents were used, draw clear water through the detergent inlet line to purge the detergent. Failure to do so may clog the detergent injector valve.
2. If a burner was used, turn OFF the burner switch and allow the pump to run cold water through the coil for several minutes.
3. Move the throttle lever to the idle position.
4. Turn the engine ON/OFF switch to the OFF position.
5. Close the fuel shutoff valve (if so equipped).
6. Turn the water supply OFF.
7. Squeeze the trigger of the trigger gun to relieve system pressure.

STORAGE

DANGER: DO NOT store flammable liquids (gasoline, diesel fuel, solvents, etc.) near a pressure washer, or in non-ventilated areas.
Protect from freezing by storing it in a heated area, or by flushing the system with antifreeze (use automotive engine antifreeze or windshield washer solvent to antifreeze). To flush the system with antifreeze, the following steps are to be followed:

1. Connect the water supply hose to the garden hose connector located on the pump. Turn on the water supply.

2. Place the detergent inlet line into a container of antifreeze.

3. Hold the wand firmly, and release the trigger of the trigger gun.

4. Start the engine. Place the throttle lever in the Full Throttle position.

5. Squeeze the trigger of the trigger gun and allow water to flow from the end of the wand. Watch for antifreeze to be drawn through the detergent inlet line. Allow the antifreeze to be drawn into the system for 5 to 10 seconds.

6. Release the trigger of the trigger gun and stop the engine.

7. Turn off the water supply and disconnect the water supply hose from the pump.

8. Attach a short length of hose (approximately 3 feet long) to the garden hose connector located on the pump. Install a funnel on the other end of the hose as shown in Figure 6.

9. Hold the wand firmly, and release the trigger of the trigger gun.

10. Start the engine. Place the throttle lever in the idle position.

11. Squeeze the trigger on the trigger gun.

12. Slowly pour antifreeze into the funnel. Continue to add antifreeze until antifreeze flows from the end of the wand.

13. Squeeze and release the trigger of the trigger gun several times to antifreeze the unloader system.

14. Release the trigger of the trigger gun. Stop engine.

15. Squeeze the trigger of the trigger gun to relieve system pressure.

For added protection, after anti-freezing, disconnect the pressure hose from the machine and remove the coil drain plug. After the coil has drained, replace the pressure hose and coil drain plug. If the pressure washer is not to be used for an extended length of time, it is recommended that the system be flushed with antifreeze for rust protection. Refer to the Gasoline Engine Manual for engine storage information.

MAINTENANCE

WARNING: Unauthorized machine modification or use of non-approved replacement parts may cause personal injury and/or property damage and will void the manufacturer’s warranty.
Pump
Lubrication: To lubricate the pump, use 30W non-detergent oil for the pump crankcase. The crankcase must be filled to the center of the red dot on the oil gauge found at the end of the pump, refer to Figure 7. During the break-in period, make sure the oil is changed after the first 40 hours of operation. After that, replace the oil every 3 months or 500 hours of operation, whichever comes first.

Proper Pump Care:

• DO NOT pump acids.
• DO NOT allow the pump to run dry.
• Winterize if storing in freezing temperatures, refer to Storage for details.
• Use a water softener on the water system is known to be high in mineral content.
• Use only high-quality detergents and follow the manufacturer’s mix recommendations.
• Flush the system with clear water immediately after using detergent solutions.
• Clean the filter screen on the detergent inlet line periodically.
• Flush the pressure washer system with antifreeze if storing for an extended period of time, refer to Storage for details.

Refer to the provided Gasoline Engine Manual for recommended maintenance.
Relief Valve
WARNING : The relief valve on this pressure washer has been factory set and sealed and is a field non-adjustable part. Tampering with the factory setting
may cause personal injury and/or property damage, and will void the manufacturer’s warranty. For replacement parts refer to Coil Outlet Assembly.
If pressure from the pump or thermal expansion should exceed safe limits, the relief valve will open, allowing high pressure to be discharged through a hose to the ground.
Caution: Inspect the relief valve annually for any obstruction.

Unloader Valve
WARNING : The unloader valve on this pressure washer has been factory set and sealed and is a field nonadjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer’s warranty.

Burner Fuel Filter
Drain any water which has accumulated in the fuel filter and clean or replace the filter element as needed.
Heating Coil
Coil Descaling: In hard water areas, scale buildup within
the heating coil will occur. Scale deposits will decrease the water temperature rise and may eventually clog the heating coil. Contact your local service center when descaling is needed.
Coil Desooting: Poor grades of fuel oil or inadequate combustion air will cause heavy soot buildup on the outside surface of the heating coil. These deposits will insulate the coil. This will restrict the airflow through the coil, further aggravating the soot buildup. Contact your local service
the center when decorating is needed.
Hour Meter
This hour meter will monitor the total hours of operation of the pressure washer to signal when routine maintenance is required.
