Frequently Asked Questions - KXA1810G Vevor

What type of oil should I use in the pump?

Use non-detergent pump oil (SAE 30 or specific pressure washer oil). Refer to the manual for the exact amount; typically about 8 oz.

How do I connect the high-pressure hose correctly?

Attach the hose to the gun first, then connect the other end to the pump outlet. Ensure the collar screws are finger-tight and the O-ring is seated properly to prevent leaks.

Can I use the pressure washer with a water tank instead of a garden hose?

Yes, it supports self-priming from a water source. Use a separate water inlet hose with a filter and prime the pump by running it with the nozzle open until water flows steadily.

What does the adjustable nozzle do?

The nozzle allows you to change the spray angle from a narrow 0° jet for stubborn dirt to a wider 40° fan for gentle rinsing. Rotate it to match the cleaning task.

How often should I clean the water filter?

Inspect and clean the inlet filter every month or more often if the water source is sandy. A clogged filter reduces pressure and can damage the pump.

The washer won't start—what should I check?

First ensure it's properly plugged into a working outlet and the GFCI is reset. Check the power cord, trigger lock, and that the unit is not in thermal overload after extended use.

Can I use bleach or other cleaners with this pressure washer?

Do not use bleach, solvents, or flammable liquids. Only use detergents labeled for pressure washers, and use the built-in detergent tank with the low-pressure nozzle.

How do I store the pressure washer for winter?

Flush the unit with clean water, then disconnect all hoses and drain the pump. Store in a dry, frost-free location. Add antifreeze specifically designed for pressure washers if freezing is unavoidable.

What safety gear should I wear while operating?

Always wear safety goggles and closed-toe shoes. Hearing protection is recommended for long sessions. Never point the high-pressure spray at people or pets.

Is the pressure washer self-priming?

Yes, it can draw water from a container via the self-priming function. Attach a suction hose with a filter, fill the pump chamber with water manually, and keep the suction end submerged.
