•Some adjustments will need to be made periodically to properly maintain your pressure washer.

•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 and check the spray gun and adjustable nozzle extension assembly for wear.A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.

WARNING

The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation.

•NEVER repair high pressure hose. Replace it.

•Replacement hose rating MUST exceed maximum pressure rating of unit.

Check Chemical Injection Hose

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.

Cleaning Chemical Injection Hose

If you used the chemical injection hose, you must flush it with clean water before stopping the engine.
