3. Place o-ring into recess. Push o-ring snugly against inline filter screen. 4. Assemble nozzle extension to spray gun, as described earlier in manual. Nozzle Maintenance A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive pump pressure.The principal cause of excessive pump pressure is a nozzle clogged or restricted with foreign materials, such as dirt, etc.To correct the problem, immediately clean the orifice following these instructions: 1. Shut off engine and turn off water supply. 2. Remove orifice from end of nozzle extension. Separate nozzle extension from spray gun.Twist nozzle clockwise to stream position. Using a 2mm (5/64) allen wrench, remove orifice from end of nozzle extension (Figure 14). 3. Remove in-line filter from other end of nozzle extension. 4. Use a small paper clip to free any foreign material clogging or restricting orifice (Figure 14). 5. Using a garden hose, remove additional debris by back flushing water through nozzle extension (Figure 15). Back flush between 30 to 60 seconds.Turn adjustable nozzle extension to stream spray and move nozzle from low to high while flushing. 6. Reinstall orifice and in-line filter into nozzle extension. DO NOT overtighten orifice with allen wrench. 7. Reconnect nozzle extension to spray gun. 8. Reconnect water supply, turn on water, and start engine. 9. Test pressure washer by operating with nozzle in high and low positions. O–Ring Maintenance Purchase an O–Ring/Maintenance Kit, part number 191922GS by contacting the nearest authorized service center. It is not included with the pressure washer.This kit includes replacement o-rings, rubber washer and water inlet filter. Refer to the instruction sheet provided in the kit to service your unit’s o-rings. Pump Oil Maintenance This model does not require any pump maintenance.The pump is pre-lubricated and sealed, requiring no additional lubrication for the life of the pump. Orifice Figure 14 — Removing and Cleaning Orifice Figure 15 — Backflushing the Nozzle • NEVER repair leaking connections with sealant of any kind. Replace o-ring or seal. The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation. WARNING SpeedClean™ 2000 PSI Pressure Washer ENGINE MAINTENANCE Protecting the Pump See the engine operator’s manual for instructions on how to properly maintain the engine. CAUTION Avoid prolonged or repeated skin contact with used motor oil. • • Used motor oil has been shown to cause skin cancer in certain laboratory animals. Thoroughly wash exposed areas with soap and water. KEEP OUT OF REACH OF CHILDREN. DON'T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS. PREPARING THE UNIT FOR STORAGE Water should not remain in the unit for long periods of time. Sediments or minerals can deposit on pump parts and “freeze” pump action. If you do not plan to use the pressure washer for more than 30 days, follow this procedure: 1. Flush detergent siphoning tube/filter by placing filter into a pail of clean water while running pressure washer in low pressure mode (adjustable nozzle in forward position). Flush for one to two minutes. 2. Shut off engine and let it cool, then remove high pressure and garden hoses. Disconnect spark plug wire from spark plug. 3. Place the spray gun, nozzle extension and high pressure hose in the accessory storage bag. 4. Empty pump of all pumped liquids by pulling recoil handle about 6 times.This should remove most liquid in pump. 5. Use PumpSaver to prevent corrosion build up and freezing of pump. 6. Store unit in a clean, dry area. To protect the pump from damage caused by mineral deposits or freezing, use PumpSaver to treat pump.This prevents freeze damage and lubricates pistons and seals. NOTE: PumpSaver is available as an optional accessory. It is not included with the pressure washer. Contact the nearest authorized service center to purchase PumpSaver. To use PumpSaver, make sure the pressure washer is turned off and disconnected from supply water. Read and follow all instructions and warnings given on the PumpSaver container. CAUTION You must protect your unit from freezing temperatures. • • Failure to do so will permanently damage your pump and render your unit inoperable. Freeze damage is not covered under warranty. CAUTION Read and follow all cautions and warnings on the PumpSaver can label. • Always wear eye protection when using PumpSaver. CAUTION PumpSaver will drip from pump after treatment and will stain wood and concrete. • Protect surfaces from dripping PumpSaver. NOTE: If PumpSaver is not available, draw RV antifreeze (non-alcohol) into the pump by pouring the solution into a 3-foot section of garden hose connected to inlet adapter and pulling recoil handle twice.
