3. Setup
Before connecting the gun, ensure your pressure washer unit is turned off and depressurized. Always wear appropriate personal protective equipment (PPE), including safety glasses, before beginning setup.
- Inspect Components: Verify that the gun and all connecting hoses are free from damage, cracks, or blockages.
- Connect High-Pressure Hose: Attach the high-pressure hose from your pressure washer to the 3/8 NPT F inlet on the Mi-T-M 16-0445 gun. Ensure the connection is secure and hand-tightened, then use a wrench to tighten an additional quarter turn if necessary, being careful not to overtighten.
- Attach Nozzle/Wand (if applicable): If your setup requires a separate wand or nozzle, connect it to the outlet of the gun. Ensure it is firmly seated and locked into place to prevent accidental detachment during operation.
- Check for Leaks: Once all connections are made, slowly turn on the water supply to the pressure washer and check for any leaks at the connection points. Address any leaks before proceeding.
4. Operating Instructions

Operation Steps:
