Replacing a worn pump restores cleaning performance while reducing equipment downtime.

Installation & Service Notes

• Shut down the pressure washer and disconnect the spark plug before servicing.
• Relieve all system pressure.
• Verify compatibility with the engine shaft, F7 flange mount, horsepower, and pressure requirements.
• Install the pump according to the manufacturer's specifications.
• Connect the water inlet and high-pressure discharge plumbing.
• Fill the crankcase with the recommended pump oil if required.
• Prime the pump with water before startup.
• Verify proper operation and inspect for leaks after installation.

Important: Never operate the pump without an adequate water supply. Running the pump dry can quickly damage internal plungers, seals, and valves, significantly reducing pump service life.

Maintenance Recommendations

• Check pump oil level and change oil according to AR maintenance schedules.
• Inspect seals, valves, and fittings during routine maintenance.
• Maintain clean, filtered inlet water to reduce internal wear.
• Flush the pump after use when pumping dirty or corrosive water.
• Use only genuine OEM AR replacement parts and approved lubricants to maintain optimum performance, reliability, and long service life.
