5. Operating Instructions
5.1 Starting the Unit
- Ensure the water supply is fully open and there are no kinks in the hose.
- Squeeze the trigger on the spray gun to purge air from the system until a steady stream of water emerges.
- Turn the power switch on the unit to the "ON" position. The motor will start when the trigger is squeezed and stop when released (Total Stop System - TSS).
5.2 Adjusting Pressure
The Imdot X99 features an adjustable pressure control via a twist-button on the unit, allowing you to select pressure from 2500 PSI to 5000 PSI.
- Locate the pressure adjustment dial on the front of the unit.
- Rotate the dial towards "MIN" for lower pressure (2500 PSI) suitable for delicate surfaces.
- Rotate the dial towards "MAX" for higher pressure (5000 PSI) for tough cleaning tasks.
- Always start with a lower pressure setting and gradually increase it to prevent surface damage.

5.3 Using Nozzles
The unit includes four quick-connect nozzles for different spray patterns:
- 0° (Red): Pin-point jet for intense cleaning of stubborn stains. Use with extreme caution.
- 15° (Yellow): Narrow spray for concentrated cleaning on hard surfaces.
- 25° (Green): Medium spray for general cleaning of decks, patios, and vehicles.
- 40° (White): Wide spray for gentle rinsing or cleaning large, delicate areas.
- Ensure the pressure cleaner is off and the trigger is locked before changing nozzles.
- Pull back the collar on the spray gun wand and insert the desired nozzle. Release the collar to lock it in place.
- Test the spray pattern on an inconspicuous area first.

5.4 Using the Foam Cannon
The included foam cannon is ideal for applying detergent or soap for vehicle washing or pre-soaking surfaces.
- Fill the 500ml soap bottle with appropriate pressure washer detergent.
- Attach the foam cannon to the spray gun wand.
- Operate the pressure cleaner. The foam cannon will mix detergent with water to create a rich foam.
- After applying detergent, remove the foam cannon and attach a rinsing nozzle (e.g., 25° or 40°) to rinse the surface thoroughly.
