Page 24: Options: High Pressure Detergent
OPTIONS: HIGH PRESSURE 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. Refer to “Risk of Bodily Injury / Detergents” pg. 11-12. Be certain to wear protective safety attire as stated on pg. 15. 2. Prepare detergent solution according to label directions. (Never pump acids, alkalines, 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.) 3. Fully immerse the detergent strainer into the detergent solution. 4. To apply solution; unlock the trigger gun and squeeze the trigger. In 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 to soak briefly. (Avoid working on hot surfaces or in direct sunlight to minimize the chances of the detergent drying, which may result in damaging painted surfaces.) Be certain to rinse a small section at a time. 5. To rinse; lock the trigger gun in the “OFF” position, securely quick- connect the desired high pressure nozzle into the end of the wand. Unlock the trigger gun 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. 6. 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. DETERGENT METERING VALVE... -
Page 25: Maintenance
Storage & Maintenance Instructions 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 engine work life. PUMP: Change the pump oil after the first 50 hours of operation. After 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 SAE20 or 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, making it larger, resulting in a pressure loss. 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. MAINTENANCE - EVERY 3 MONTHS CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump oil after the first 50 hours of operation. After initial change, every 3 months or 500 hour intervals are recommended. If oil appears dirty or milky, changes may be required in greater frequency. Use SAE20 or 30 non-detergent pump oil and fill only to the center of the oil sight glass. DO NOT overfill. REPLACE HIGH PRESSURE NOZZLE: Water flow through the spray nozzle will erode the orifice, making it larger, resulting in a pressure loss. 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. BELT INSPECTION: Ensure unit is off and remove the beltguards. Inspect the v-belt for wear and tightness. If the v-belt needs to be replaced or tightened, follow the procedures listed below: Replacement: 1. Loosen the four pump mounting bolts (A). - Page 26 BELT TENSION ADJUSTMENT: To maintain peak performance of your pressure washer, it may be necessary to adjust the belt tension on occasion. Follow the procedure outlined below. 1. Remove the belt guard and loosen the two nuts on each side of the pump (Reference A). There are a total of 4 nuts. 2. Turn the cap screw (Reference B) clockwise until a 1/4 inch belt deflection is noticed between the pulleys. 3. Tighten the side nuts (Reference A). 4. Put a straight edge across both pulleys. Pulley alignment is critical for proper performance and service life. If necessary, loosen one set of pulley screws and adjust in or out to properly align. Tighten the pulley screws and check the tension again. 5. Replace the beltguard and tighten the fasteners securely. 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 efficiency and avoid inefficient 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 off. This will cause the burner to turn on and off. Look for a smoke puff when the burner ignites. 7. Repeat steps 5 and 6 until a smoke puff is noticed. Record the Air Shutter Setting. 8. The difference between the recorded settings in steps 4 and 7 is the combustion window. Set the dial 1/2 way between these settings. NOTICE If you are unable to detect a setting on either step 3 or 7, more or less ...
