How to Setup the WashR PRO

Setting up your Bigboi WASHR PRO is straightforward. Follow these steps to ensure your pressure washer is ready for use:

Step 1: Refer to Adding Oil to the Triplex Pump

Step 2: Connecting Spray Wand to Spray Gun

1. Pull back the slip ring on the quick-connect socket on the pressure gun.
2. Insert the quick-connect plug on the gun lance into the socket.
3. Release the slip ring on the female quick-connect socket and twist. Listen for a CLICK to ensure both quick-connects are coupled.
4. Pull the lance and gun in opposite directions to ensure they do not separate.

Step 3: Attaching High-Pressure Hose to Spray Gun

1. Attach the quick-connect socket end of the pressure hose onto the pressure gun. Pull on the hose to ensure a tight connection.

Step 4: Connect Hose and Water Supply to Pump

1. Attach the other end of the high-pressure hose to the high-pressure outlet on the pump. Pull down on the collar of the quick connect, slide it onto the pump, and let go of the collar. Pull on the hose to ensure a tight connection.
2. Before connecting the garden hose to the water inlet, inspect the inlet screen. Clean the screen if it contains debris or replace it if damaged. DO NOT run the pressure washer if the inlet screen is damaged.
3. Run water through your garden hose for 30 seconds to clean out any debris.

IMPORTANT: DO NOT siphon standing water for the water supply. Use ONLY cold water (less than 104°F/40°C). 4. Connect the garden hose (not to exceed 50 feet in length and with an ID no less than 1/2") to the water inlet. Tighten by hand. 5. Turn ON the water, squeeze the trigger to purge the pump of air and impurities.

Step 5: Connect the Electric Supply

1. Push the switch to the "OFF" position.
2. Connect the power cord to the socket on the main power source. Extension cords are not recommended.

Step 6: Using Extension Cords

If extension cords are used, ensure they feature IPX5 protection level. The cross-section of the extension cable should be proportionate to its length. The longer the cord, the greater its cross-section should be. Using extension cords that are too long can cause a voltage drop, resulting in the motor running slower and potentially causing damage. Using extension cords with a smaller than recommended wire gauge can overheat, melt, and/or cause fires.

By following these steps, you ensure your WASHR PRO is set up correctly and safely. If you encounter any issues, refer to our troubleshooting guide or contact our support team for assistance.
