4. Setup Instructions

1. Unpack Components: Carefully remove all parts from the packaging and inspect for any damage.
2. Assemble Handle: Attach the handle assembly to the cleaning head according to the diagrams provided in the packaging. Ensure all fasteners are securely tightened.
3. Connect High-Pressure Hose: Connect one end of the high-pressure hose to the inlet on the cleaning head and the other end to the outlet of the trigger spray gun. Ensure connections are tight to prevent leaks.
4. Connect to Pressure Washer: Attach the trigger spray gun to your pressure washer's high-pressure hose. Verify that your pressure washer meets the required specifications:
   • Pressure: Up to 4000 PSI
   • Flow Rate: 3.0 to 5.0 GPM

   Note: Using a pressure washer with insufficient GPM may result in reduced cleaning performance and the unit not operating optimally.

5. Water Supply: Connect your pressure washer to a suitable water supply.

5. Operating Instructions

1. Prepare Area: Clear the cleaning area of any loose debris, furniture, or obstacles.
2. Start Pressure Washer: Follow your pressure washer's instructions to start the engine/motor and prime the pump.
3. Engage Surface Cleaner: With the pressure washer running, depress the trigger on the spray gun. The rotating spray bar inside the cleaning head will begin to spin.
4. Begin Cleaning: Place the surface cleaner flat on the surface to be cleaned. Guide the cleaner slowly and steadily over the area, overlapping each pass slightly to ensure even cleaning. Avoid lifting the cleaner off the surface while the trigger is depressed, as this can cause uneven cleaning patterns.
5. Hot Water Use: This unit is compatible with hot water pressure washers. Follow your pressure washer's guidelines for hot water operation.
6. Stop Operation: To stop cleaning, release the trigger on the spray gun. To completely shut down, turn off your pressure washer and relieve any remaining system pressure.

6. Maintenance

The Mi-T-M AW-7020-8003 Rotary Surface Cleaner is designed for low maintenance, featuring a heat-treated sealed pressure swivel that requires no regular lubrication or servicing.

• Nozzle Inspection: Periodically inspect the spray nozzles located on the rotating bar for clogs or damage. If a nozzle is clogged, carefully remove it and clear any debris using a small wire or nozzle cleaning tool. Replace damaged nozzles immediately to maintain optimal performance.
• Hose and Connection Check: Regularly inspect the high-pressure hose and all connections for wear, leaks, or damage. Replace any worn or damaged components.
• Storage: After each use, flush the unit with clean water to remove any chemical residues. Store the surface cleaner in a clean, dry place, protected from freezing temperatures.

7. Troubleshooting

• Uneven Cleaning / Streaks:
  • Cause: Clogged or damaged spray nozzles.
  • Solution: Inspect and clean or replace nozzles.
  • Cause: Moving the cleaner too quickly.
  • Solution: Guide the cleaner at a slower, more consistent pace, ensuring slight overlap between passes.
• Poor Cleaning Performance / Low Rotation:
  • Cause: Insufficient GPM or PSI from the pressure washer.
  • Solution: Ensure your pressure washer meets the minimum requirements of 3.0 GPM and adequate PSI for the task.
  • Cause: Clogged nozzles.
  • Solution: Inspect and clean nozzles.
• Leaks from Connections:
  • Cause: Loose connections or worn O-rings/seals.
  • Solution: Tighten all connections. Inspect and replace O-rings or seals if damaged.
