2. Important Safety Instructions
Read and understand all safety warnings and operating instructions before using this parts washer. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Solvent Compatibility: This parts washer is designed exclusively for use with water-based, non-corrosive cleaning solutions. Using volatile solvents such as gasoline, toluene, diesel, or mineral spirits will damage the pump and may create a fire hazard.
- Electrical Safety: Ensure the unit is connected to a properly grounded 110V-120V, 60Hz electrical outlet. Do not operate with damaged cords or plugs. Keep the power cord away from heat, oil, sharp edges, or moving parts.
- Ventilation: Operate the parts washer in a well-ventilated area to prevent the buildup of fumes from cleaning solutions.
- Personal Protective Equipment: Always wear appropriate personal protective equipment, including safety glasses and chemical-resistant gloves, when operating the parts washer.
- Lid Closure: Keep the lid closed when the unit is not in use to prevent evaporation and contamination.
- Children and Bystanders: Keep children and bystanders away from the operating area.

3. Setup Guide
Follow these steps to set up your Redsun Portable Parts Washer:
- Unpack Components: Carefully remove all components from the packaging. Verify that all parts are present: the main tank, hinged lid, removable parts shelf, parts basket, flow-thru brush with tube, and pump assembly.
- Position the Washer: Place the parts washer on a stable, level surface in a well-ventilated area. Ensure there is sufficient space around the unit for safe operation and access.
- Install Removable Tray: Place the removable parts shelf and basket inside the tank. These are designed to hold parts during cleaning and allow debris to settle below.
- Connect Flow-Thru Brush: Connect the flow-thru brush hose to the pump outlet. Ensure the connection is secure to prevent leaks.
- Fill with Cleaning Solution: Pour the recommended water-based, non-corrosive cleaning solution into the tank. Do not exceed the maximum fill line, which is approximately 3.5 gallons (13.2 liters) of solvent capacity, or 5 gallons total tank capacity. Ensure the pump is fully submerged.
- Connect Power: Plug the power cord into a grounded 110V-120V, 60Hz electrical outlet.

4. Operating Instructions
Once the parts washer is set up and filled with the appropriate cleaning solution, follow these steps for operation:
- Power On: Flip the water-resistant power switch to the 'ON' position. The pump will begin circulating the cleaning solution.
- Position Parts: Place the parts to be cleaned on the removable parts shelf or in the parts basket. For smaller items, the basket is ideal.
- Use Flow-Thru Brush: Direct the flexible metal nozzle of the flow-thru brush towards the parts. The 180-degree rotating nozzle allows for precise application of the cleaning solution. Use the brush to scrub away dirt, grease, and grime.
- Soaking: For heavily soiled parts, you may allow them to soak in the cleaning solution for a period. Ensure the parts are fully submerged.
- Inspect and Rinse: After cleaning, inspect the parts. For best results, rinse cleaned parts with clean water and dry them thoroughly to prevent rust.
- Power Off: When finished cleaning, flip the power switch to the 'OFF' position.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your parts washer.
- Draining and Cleaning: After extended use or when the cleaning solution becomes excessively dirty, drain the tank. Remove the parts shelf and basket, and clean the interior of the tank. Dispose of used cleaning solution according to local environmental regulations.
- Pump Inspection: Periodically inspect the pump for any blockages or damage. The pump has a grating that acts as a coarse filter; ensure it is clear of large debris.
- Storage: When not in use, especially for prolonged periods, it is recommended to drain the cleaning solution, clean the tank, and allow it to dry. Leaving the unit full with solution for extended periods, particularly with metal parts inside, may lead to paint degradation or rust on hinges due to moisture. Store with the lid open to allow air circulation if completely dry.
- Exterior Cleaning: Wipe down the exterior of the parts washer with a damp cloth to remove any spills or grime.
6. Troubleshooting
Refer to this section for common issues and their solutions.
- No Power:
- Check if the power cord is securely plugged into a functional electrical outlet.
- Ensure the power switch is in the 'ON' position.
- Verify the circuit breaker or fuse for the outlet has not tripped.
- Pump Not Circulating / Low Flow:
- Ensure the tank has sufficient cleaning solution and the pump is fully submerged.
- Check the pump intake for blockages from debris. Clean if necessary.
- Inspect the hose and nozzle for kinks or obstructions.
- Confirm that only water-based solvents are used. Non-compatible solvents can damage the pump.
- Excessive Splashing:
- Adjust the angle of the flexible nozzle to reduce splashing.
- Ensure the parts are positioned correctly within the tank.
