CAT Electric Pressure Washer 1800 PSI 2.0 GPM Instruction Manual

1. Important Safety Information

Always read and understand all safety warnings and instructions before operating the pressure washer. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.

• Electrical Safety: This unit is equipped with a Ground Fault Circuit Interrupter (GFCI) plug for your safety. Always ensure the GFCI is reset before plugging into an electrical outlet. Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and the power requirements of the pressure washer.
• Water Connections: Ensure all water connections are secure and leak-free. Use only the recommended 1/4" M22-15mm rubber hose. Using incompatible hoses (e.g., M22-14mm) may cause leaks and damage to the unit.
• High Pressure Hazard: The pressure washer produces a high-pressure stream that can cause serious injury. Never direct the spray at people, pets, or electrical devices. Always wear appropriate eye protection.
• Chemical Use: When using detergents, follow the manufacturer's instructions for dilution and application. Avoid contact with skin and eyes.
• Stability: Operate the pressure washer on a stable, level surface to prevent tipping.

3. Setup

Follow these steps to correctly set up your pressure washer before first use.

1. Unpack Components: Carefully remove all parts from the packaging. Ensure all accessories listed in the product overview are present.
2. Connect High-Pressure Hose: Attach one end of the 20-foot high-pressure rubber hose (M22-15mm) to the high-pressure outlet on the front of the pressure washer unit. Securely twist until tight. Attach the other end to the spray gun.
3. Connect Water Supply: Connect your garden hose (not included) to the water inlet located at the rear of the pressure washer. Ensure this connection is hand-tight to prevent leaks.
4. Fill Detergent Tank (Optional): If using detergent, unscrew the cap of the 600ml foam blaster and fill it with your desired pressure washer-safe detergent. Reattach the cap securely.
5. Attach Nozzle: Select the appropriate quick-connect nozzle for your task (0°, 15°, 25°, or 40°) and insert it into the end of the spray lance until it clicks into place. If using the foam blaster, attach it directly to the spray gun.
6. Electrical Connection: Before plugging in, ensure the GFCI plug is reset (press the 'Reset' button if needed). Plug the 35-foot electric cord into a suitable outdoor electrical outlet.

4. Operating Instructions

Once the pressure washer is set up, follow these steps for safe and effective operation.

1. Turn on Water Supply: Fully open the water faucet connected to your garden hose. Allow water to flow through the spray gun for a few seconds to purge any air from the system.
2. Power On: Press the power button on the pressure washer unit to turn it on. The motor will start.
3. Begin Cleaning: Aim the spray gun at the surface to be cleaned, keeping a safe distance. Squeeze the trigger to start the high-pressure water flow. Adjust your distance and angle for optimal cleaning without damaging the surface.
4. Using Detergent: If using the foam blaster, ensure it is attached and the detergent tank is filled. The pressure washer will automatically mix the detergent with the water. Apply detergent to the surface, allow it to soak for a few minutes (do not let it dry), then rinse thoroughly with a high-pressure nozzle.
5. Changing Nozzles: To change nozzles, release the spray gun trigger and engage the safety lock. Pull back the collar on the lance, remove the current nozzle, and insert the new one until it clicks into place.
6. Shutting Down: When finished, release the spray gun trigger and engage the safety lock. Turn off the power switch on the unit. Turn off the water supply. Squeeze the spray gun trigger to release any remaining pressure in the system. Disconnect the hoses and store the unit.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pressure washer.

• After Each Use: Always drain all water from the pump and hoses to prevent damage, especially in freezing conditions.
• Nozzle Cleaning: Periodically clean the nozzles to remove any blockages that may affect spray pattern or pressure.
• Hose Inspection: Regularly inspect the high-pressure hose for any signs of wear, cuts, or leaks. Replace immediately if damaged.
• Winterization: If storing the unit in an area where temperatures may drop below freezing, it is crucial to winterize the pump. Use a pump protector or an anti-corrosion/antifreeze product specifically designed for pressure washers.

6. Troubleshooting

If you encounter issues with your pressure washer, refer to the following common problems and solutions:

• Unit Does Not Turn On:
  • Check if the GFCI plug needs to be reset. Press the 'Reset' button.
  • Ensure the power cord is securely plugged into a working outlet.
  • Verify the power switch on the unit is in the 'ON' position.
• Water Leakage:
  • Confirm that the correct 1/4" M22-15mm rubber hose is being used. Incompatible hoses (e.g., M22-14mm) can cause leaks.
  • Tighten all hose connections securely.
  • Inspect O-rings and seals for damage and replace if necessary.
• Low Pressure:
  • Ensure the water supply faucet is fully open and the water flow is adequate.
  • Check for kinks or blockages in the garden hose or high-pressure hose.
  • Clean or replace clogged nozzles.
  • Ensure the water inlet filter is clean and free of debris.
• Detergent Not Dispensing:
  • Ensure the foam blaster is correctly attached and the detergent tank is filled.
  • Do not overfill the detergent tank; some users report better foaming when filled halfway.
  • Verify that a low-pressure nozzle (or the foam blaster itself) is selected, as detergent typically dispenses only under low-pressure settings.
