FAQs
Is this kit compatible with my Bosch pressure washer model XYZ?
This kit is specifically designed for the Bosch AQT series of domestic pressure washers that use the AQT bayonet fitting. Please check your pressure washer's manual or look for the AQT designation and bayonet connection type to confirm compatibility. It is not suitable for standard Bosch or other brands' pressure washers.
What is the maximum pressure this trigger gun can handle?
The specifications indicate a maximum pressure of 1750 PSI (120 Bar).
Can I use this with a non-Bosch pressure washer hose?
No, this kit is designed exclusively for Bosch AQT pressure washers and compatible Bosch AQT bayonet hoses. It will not connect securely or function correctly with hoses from other brands or non-AQT Bosch hoses.
How do I adjust the spray pattern on the nozzle?
The variable nozzle typically rotates. Turn the nozzle head to adjust the spray pattern from a wide fan for broader coverage to a narrow jet for concentrated cleaning power.
What does 'ergonomic design' mean for the trigger gun?
An ergonomic design means the trigger gun has been shaped and balanced for comfort and ease of use, reducing strain on your hand and wrist during operation.
What is included in the kit?
The kit includes one trigger gun, one lance extension, and one variable nozzle.
How do I clean the nozzle if it gets clogged?
Disconnect the nozzle from the lance. You can try rinsing it with water. If debris is lodged, use a thin, non-metallic object (like a wooden toothpick) to carefully dislodge any blockages from the nozzle opening.
Troubleshooting
Trigger gun not spraying water
Ensure the pressure washer is powered on, water supply is on, and the trigger is fully depressed. Check that the bayonet connection to the hose is secure and that the variable nozzle is not set to 'off' or a fully closed position.
Low water pressure or weak spray
Check that the water inlet filter on the pressure washer is clean. Ensure the variable nozzle is adjusted to a finer spray setting. Verify the connection to the pressure washer hose is fully secured. Check for any kinks in the hose.
Leaking from the trigger gun or lance connection
Ensure the bayonet fittings are completely locked into place. Inspect the O-rings on the fittings for damage or wear and replace if necessary. Do not overtighten connections.
Difficulty attaching or detaching parts
Make sure you are using the correct Bosch AQT bayonet fittings. Press and hold the release button firmly when detaching. Ensure debris is not blocking the connection points.
