Operation

1. Adjustable Pressure Control

The pump features an upgraded unloader for easy pressure adjustment without tools. Simply twist the knob by hand:

• Turn counterclockwise to reduce pressure for lighter tasks like washing vehicles.
• Turn clockwise to increase pressure for tougher jobs such as cleaning driveways.

This image illustrates the hand-adjustable unloader, allowing users to easily increase or decrease pressure for different cleaning tasks.

2. Self-Priming Function

This pump includes a self-priming feature, allowing it to draw water from various sources beyond a direct faucet connection. This provides flexibility for use with buckets, pools, or tanks, making it suitable for remote locations or agricultural work.

Maintenance

1. General Care

The pump is constructed from durable die-cast aluminum, designed for rust resistance and long-term use. A thermal relief valve is integrated to prevent overheating by releasing hot water and allowing cooler water to enter, protecting the pump during operation.

2. Oil Changes

Regular oil changes are crucial for maintaining pump performance and extending its lifespan. It is recommended to change the pump oil every 200 hours of operation.

This image highlights the necessity of adding oil for lasting performance and indicates the recommended oil change interval of every 200 hours.

Troubleshooting

If you encounter issues with your WOJET Pressure Washer Pump, consider the following common troubleshooting steps:

• No Water Flow: Check that the water supply is fully open and free of kinks. Ensure all hose connections are secure and not leaking. Verify the inlet filter is clean and not obstructed.
• Low Pressure: Confirm the pressure adjustment knob is set to the desired level (clockwise for higher pressure). Inspect the spray nozzle for blockages or wear. Ensure the engine is running at its optimal RPM.
• Pump Overheating: Check the water supply for adequate flow. Ensure the thermal relief valve is functioning correctly. Avoid prolonged bypass operation without spraying.
• Leaks: Inspect all connections for tightness. Check O-rings and seals for damage and replace if necessary.
• Engine Issues: Refer to your pressure washer engine's specific instruction manual for engine-related troubleshooting.

For persistent issues, please contact customer support.
