3. Setup
- Charge the Battery: Connect the battery to the charging station and plug it into a power outlet. Ensure the battery is fully charged before first use.
- Attach the Water Inlet Hose: Securely connect the water inlet hose to the designated port on the cleaning machine.
- Prepare Water Source:
- Bucket Use: Place the filter end of the water inlet hose into a bucket filled with clean water. For optimal performance, ensure the filter remains submerged at the bottom of the bucket. Adding a small weight to the filter may help keep it submerged and prevent air intake.
- Direct Hose Connection: If using a direct water hose, attach the appropriate adapter (if included) to the water inlet hose and connect it to your garden hose.
- Attach Spray Nozzle/Accessory: Select the desired spray nozzle (e.g., 0-degree, 40-degree, or foam dispenser) and securely attach it to the end of the spray wand.
- Insert Battery: Slide the charged battery into the battery compartment on the main unit until it clicks into place.
4. Operating Instructions
- Power On: Press and hold the power button (or trigger) to start the machine. The pump will begin to draw water.
- Prime the Pump: If using a bucket, it may take a few seconds for water to be drawn and for the pressure to build. Point the nozzle away from people and objects until a steady stream of water is achieved.
- Select Spray Pattern: Rotate the nozzle head to switch between different spray patterns (e.g., direct jet, fan spray).
- Apply Detergent (Optional): If using the foam cleaning attachment, fill the soap dispenser with appropriate car wash soap or cleaning solution. Attach it to the machine and spray evenly over the surface.
- Clean the Surface: Hold the machine at an appropriate distance from the surface to be cleaned. Move the spray in a consistent pattern to remove dirt and grime.
- Rinse: After applying soap or cleaning, switch to a rinse spray pattern (e.g., fan spray) and thoroughly rinse the surface until all soap residue is gone.
- Power Off: Release the power button/trigger to stop the machine. Remove the battery when finished.
5. Maintenance
- Clean the Filter: Regularly inspect and clean the stainless steel filter on the water inlet hose to prevent blockages and ensure optimal water flow. Rinse it under running water to remove debris.
- Rinse After Use: After using soap or chemicals, run clean water through the machine for a few minutes to flush out any remaining residue and prevent corrosion.
- Battery Care: Store the battery in a cool, dry place. Do not expose it to extreme temperatures. Recharge the battery periodically if not used for extended periods to maintain its lifespan.
- Storage: Disconnect all hoses and attachments. Drain any remaining water from the machine. Store the unit and accessories in a dry, protected area, away from direct sunlight and freezing temperatures.
6. Troubleshooting
- No Water Flow or Low Pressure:
- Check if the water inlet hose filter is clean and not clogged.
- Ensure the water inlet hose is fully submerged in the water source (if using a bucket) and that the filter is at the bottom. Air intake can prevent proper priming.
- Verify that all connections are secure and there are no kinks in the hose.
- Ensure the battery is fully charged.
- Machine Not Turning On:
- Check if the battery is properly inserted and fully charged.
- Ensure the power button/trigger is being pressed correctly.
- Leaking Connections:
- Tighten all hose and attachment connections.
- Inspect O-rings and seals for damage and replace if necessary.
