Generac Portable Products 2,100 PSI High Pressure Washer GENERAL MAINTENANCE RECOMMENDATIONS CAUTION! Water spraying from a leak is capable of injecting material into skin. Inspect hose each time before using it. Never repair a high pressure hose. Replace it with another hose that exceeds the maximum pressure rating of your pressure washer. The pressure washer warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the high pressure washer as instructed in this manual.
Check Detergent Siphoning Tube Some adjustments will need to be made periodically to properly maintain your high pressure washer. Check the spray gun and adjustable nozzle extension assembly for wear. Examine the filter on the detergent tube and clean if clogged. The tube should fit tightly on the barbed fitting. Examine the tube for leaks or tears. Replace the filter or tube if either is damaged. All maintenance in this manual and the engine owner’s manual should be made at least once each season. Once a year you should clean or replace the spark plug, clean or replace the air filter.
A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer. Please refer to your engine owner’s manual for more details. Cleaning Detergent Siphoning Tube If you used the detergent siphoning tube, you must flush it with clean water before stopping the engine. Place the chemical injection siphon/filter in a bucket full of clean water. BEFORE EACH USE Check engine oil level. Check water inlet screen for damage. Check in-line filter for damage.
