Setup and Installation
Follow these steps to install your new pressure washer pump:
- Preparation: Ensure the pressure washer engine is off and cooled down. Disconnect the spark plug wire for safety. Remove the old pump by unbolting it from the engine.
- Clean Shaft: Clean the engine's drive shaft thoroughly to remove any rust or debris.
- Install Shaft Key: Insert the provided shaft key into the keyway on the engine's drive shaft. Applying a small amount of lubricant to the shaft key can help it stay in place during installation.
- Mount New Pump: Carefully slide the new pump onto the engine's drive shaft, aligning the keyway on the pump with the shaft key. Ensure the pump seats fully against the engine.
- Secure Pump: Use the provided mounting bolts and lock washers to secure the pump to the engine. Tighten the bolts evenly and securely.
- Connect Hoses: Connect the water inlet hose to the pump's inlet port and the high-pressure outlet hose to the pump's outlet spin connector. Ensure all connections are tight.
- Install Thermal Relief Valve: Install the thermal relief valve into its designated port on the pump.
- Final Check: Double-check all connections and ensure the pump is securely mounted before proceeding to operation.
Operating Instructions
Once the pump is installed, follow your pressure washer's engine starting procedure. Ensure a continuous water supply is connected and turned on before starting the engine. Squeeze the spray gun trigger to purge air from the system before applying pressure. Refer to your pressure washer's main manual for specific operating instructions.
Maintenance
Regular maintenance ensures the longevity and performance of your pump:
- Water Supply: Always ensure a clean, adequate water supply to prevent cavitation and pump damage.
- Winterization: In freezing temperatures, drain all water from the pump or use a pump protector/antifreeze solution to prevent damage.
- Storage: Store the pressure washer in a dry, protected area when not in use.
- Leak Checks: Periodically inspect for leaks around connections and seals. Address any leaks promptly.
Troubleshooting
If you encounter issues, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No pressure or low pressure | Insufficient water supply, air in pump, clogged nozzle, worn seals | Check water source, purge air by squeezing trigger, clean/replace nozzle, inspect/replace seals. |
