Frequently Asked Questions

Do I need to assemble anything before first use?

Yes. You must connect the hose, inlet connector, spray gun, and ensure the machine is correctly powered and supplied with water before operation.

Why is no water coming out of the spray gun?

This usually happens if:

• The water supply is not fully turned on.
• The hose is not properly connected.
• Air is trapped in the system (needs priming).

Can I run the pressure washer without water?

No. Running the machine without water can cause serious damage to the pump.

Why does the machine need priming?

Priming removes air from the system and ensures a steady flow of water through the pump before pressure is applied.

What should I do if there is a leak?

Check that:

• All hose connections are hand-tight.
• The inlet connector is properly seated.
• The washer is not damaged or cracked at connection points.

Can I change spray patterns while using it?

Yes. You can switch nozzles or adjust the spray pattern depending on the cleaning task, but always release the trigger before changing attachments.
