•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.

Check Gun and Nozzle Extension

Examine the hose connection to the spray gun and make sure it is secure.Test the trigger by pressing it and making sure it “springs back” into place when you release it. Put the trigger lock in the ON position and test the trigger. You should not be able to press the trigger.
