How to use

Confirm that your pressure washer, hose and nozzle are rated for pressures up to 345 bar before connecting the gun. Securely attach the 20 mm connection to the hose or fitting and ensure all threaded or quick-connect joints are tightened according to the hose/fitting manufacturer instructions. Use the trigger to start and stop water flow; modulate pressure by combining the gun control with the pressure washer’s built-in settings or adjustable nozzle. Inspect seals and connections for leaks before each use and avoid sudden impacts or bending forces on the gun and connection.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. Do not exceed the specified maximum pressure and avoid using the gun with incompatible chemicals or abrasive media unless the materials are rated for such use. Regularly check O-rings and seals and replace worn parts to maintain a safe, leak-free connection.
