Coil Outlet Rupture Disk Pressure Hose Figure - Pressure Hose Installation 7
OPERATOR S MANUAL PRESSURE WASHER Getting Started IMPORTANT: Proper initial installation of 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 machine indoors or in an enclosed area, as exhaust fumes may be hazardous to your health. DANGER: DO NOT operate 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 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 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 Installation Instructions 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 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 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 00 o 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 3000 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 0W40) Burner fuel (No. or No.2 home heating fuel or diesel) 8
Oil Burner Burner Air Adjustment: The oil burner on this machine is preset for operation at altitudes below 3000 feet. If operated at higher altitudes, it may be necessary to adjust the air shutter and air band setting. Adjust the air shutter for a # or #2 smoke spot on the Bacharach scale. To adjust, start machine and turn burner ON. Loosen two locking screws found in the air shutter openings and close air shutter until black smoke appears from burner exhaust vent. Note air shutter position. Next, slowly open the air shutter until white smoke just starts to appear. Turn air shutter halfway back to the black smoke position previously noted. Tighten locking screws.

CAUTION: If white smoke appears from burner exhaust vent during start-up or operation, discontinue use and readjust air bands. NOTE: If a flue is installed, have a professional serviceman adjust your burner for a # or #2 smoke spot on the Bacharach scale. 9
OPERATOR S MANUAL PRESSURE WASHER Before Starting. Read all manuals provided with this pressure washer. Become familiar with 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 water supply hose to the garden hose connector located on pump. The water faucet and supply hose must be capable of providing a minimum of 3.5 gallons per minute (GPM). 3. Fill oil burner fuel tank. Use kerosene, # grade home heating oil, # or #2 diesel fuel. DO NOT USE GAS- OLINE, CRANKCASE OIL DRAININGS, OR WASTE OIL. WARNING: DO NOT fill engine fuel tank while engine is running or hot. Let engine cool before refueling or spontaneous fire may result. Fuel spillage or vapors could ignite if engine is hot. 4. Fill the engine fuel tank. Do not overfill, fill to the bottom of filler neck only. Use lead free gasoline minimum 86 octane. DO NOT use gasoline containing more than 5% MTBE, 5% methanol or 0% 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 instructions on the detergent container. IMPORTANT: Before installing 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 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 wand, refer to Figure 4. Manual Trigger Lock Operation Instructions Pressure Nozzle Figure 4 - Nozzle Installation/Manual Trigger Lock 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 wand or trigger gun at yourself or at any person. Bodily injury may result from water under high pressure. WARNING: Wear eye, ear, hand, foot and skin protection at all times while operating pressure washer. IMPORTANT: The water must be turned on before starting. Running the pump dry will cause damage and void warranty. IMPORTANT: DO NOT allow the machine to run with trigger of the trigger gun released for more than 0 minutes at any one time or damage to pump may occur.. Turn ON water supply. 2. Hold wand firmly, release trigger of trigger gun. 3. Place engine ON/OFF switch in the ON position. 4. Open fuel shutoff valve (if so equipped). Move choke lever to full choke position, (choke may not be needed on warm engine). Move throttle lever to 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 choke lever until engine runs smoothly. When engine warms, move choke lever to NO CHOKE position. Move throttle lever to 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 engine fails to start, refer to Troubleshooting Guide in this manual. 7. Squeeze trigger of trigger gun and allow air to purge from system. 8. If HOT water is desired, adjust the thermostat to the proper temperature and turn 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 Oil Burner section under Installation. If smoke continues, contact Customer Service at -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. 0
To Clean DANGER: DO NOT place hands or fingers in front of 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.. Insert detergent inlet line into container of mixed detergent. 2. Completely open detergent control knob located on the side of the detergent injector valve. Refer to Figure 5. Water Adjustment Knob Water Increase Detergent Off Figure 5 - Detergent Injector Valve 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 o 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. Operation Instructions Water Decrease Detergent On Detergent Control Knob 8. The nozzle should be 2" to 24" from work, closer for tough areas. Be careful on painted or delicate surfaces, the pressure may damage 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. 0. Turn the side detergent control knob clockwise (CW) for detergent decrease. Wait for detergent to clear. Always rinse with cold water after using 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. If detergents were used, draw clear water through the detergent inlet line to purge detergent. Failure to do so may clog detergent injector valve. 2. If burner was used, turn OFF burner switch and allow pump to run cold water through coil for several minutes. 3. Move throttle lever to idle position. 4. Turn engine ON/OFF switch to the OFF position. 5. Close fuel shutoff valve (if so equipped). 6. Turn water supply OFF. 7. Squeeze trigger of trigger gun to relieve system pressure. STORAGE DANGER: DO NOT store flammable liquids (gasoline, diesel fuel, solvents, etc.) near pressure washer, or in non-ventilated areas. Protect from freezing by storing in a heated area, or by flushing the system with antifreeze (use an automotive engine antifreeze or windshield washer solvent to antifreeze). To flush the system with antifreeze, the following steps are to be followed:. Connect the water supply hose to the garden hose connector located on the pump. Turn on water supply. 2. Place the detergent inlet line into a container of antifreeze. 3. Hold wand firmly, release trigger of trigger gun. 4. Start engine. Place throttle lever in Full Throttle position. 5.
