Installation Instructions

Follow these steps to properly install your new pressure washer pump. Ensure the pressure washer engine is turned off and completely cooled before beginning installation.

1. Prepare the Pressure Washer: Disconnect the spark plug wire to prevent accidental starting. Drain any remaining water from the old pump and hoses.
2. Remove Old Pump: Locate the bolts securing the old pump to the engine. Typically, there are three bolts. Carefully remove these bolts and detach the old pump from the engine shaft. You may need to gently pry the old pump off if it is seized.
3. Inspect Engine Shaft: Clean the engine shaft thoroughly. Ensure there is no rust or debris. Check the keyway for any damage.
4. Install Shaft Key: If your engine shaft requires a key, insert the shaft key into the keyway on the engine shaft.

Operation

Once the pump is installed, follow your pressure washer's engine starting procedure. Ensure a continuous water supply to the pump before starting the engine to prevent damage.

• Water Supply: Always connect the garden hose to a reliable water source and turn it on fully before starting the pressure washer engine. Running the pump dry will cause severe damage.
• Engine Start: Follow the manufacturer's instructions for starting your specific pressure washer engine.
• Engage Spray Gun: Squeeze the trigger on the spray gun to release air from the system and allow water to flow smoothly.
• Adjust Pressure/Nozzle: Use appropriate nozzles for your cleaning task. The pump delivers 2500-2800 PSI, suitable for various cleaning applications.
• Chemical Injection: If using the chemical injector, ensure the detergent siphon tube is placed into a pressure washer safe detergent container. The chemical injector typically operates at low pressure.
