This pressure washer is designed for light-to-medium duty residential cleaning tasks. Before use, ensure the machine is on a stable surface, the water supply is connected, and the GFCI power cord is tested. Always wear safety gear, including eye and hearing protection, and non-slip footwear.
Product Overview
The unit features a trigger gun, adjustable nozzle, and a Total Stop System (TSS) that automatically turns the motor off when the trigger is released to save energy and protect the pump.

Assembly

- Handle: Slide the handle into the alignment grooves on the top of the machine and secure it with the two provided Phillips head screws.
- Holders: Slide the trigger gun holder and cord holder into their respective positions on the machine body.
Connections
- Spray Gun: Attach the spray wand to the trigger gun and lock it by turning the rotatable end-piece.
- High-Pressure Hose: Connect one end to the trigger gun until it clicks, and screw the other end onto the water outlet on the machine.
- Water Supply: Attach the garden hose adapter to the water inlet, then connect your garden hose. Ensure the water supply is clean and not hot.
Operation
Before starting, ensure the motor switch is in the OFF (0) position. Plug the unit into a GFCI-protected outlet and reset the GFCI if necessary. Turn on the water supply, unlock the safety lock on the trigger, and squeeze the trigger to bleed air from the system. Once water flows steadily, turn the switch to the ON (I) position while keeping the trigger pressed.
Using Nozzles
The washer includes an adjustable nozzle. You can adjust the pressure and spray pattern (from pencil spray to fan spray) by turning the adjustment knobs on the nozzle.
Maintenance


- Filter: Regularly check and clean the water inlet filter by rinsing it with warm water to prevent clogging.
- Nozzle: If the nozzle becomes clogged, use the provided needle clean-out tool to remove debris.
Storage and Winterizing
Always store the unit indoors in a frost-free area. If storing in temperatures below 32°F (0°C), flush the system with non-corrosive/non-toxic anti-freeze or a pump protector to prevent freeze damage, which is not covered by the warranty.
Troubleshooting
If the machine fails to start, check the power connection and GFCI. If pressure fluctuates or the machine pulsates, check for air in the hose, clean the water filter, or ensure the water supply is adequate. If the machine stops, it may be due to the thermal sensor; allow it to cool for 5 minutes.
