Proper setup is crucial for safe and effective operation.

Inspect Components: Before each use, inspect the trigger gun, hoses, and all connections for any signs of damage, wear, or leaks. Do not use if damaged.
Connect Inlet Hose: Connect the high-pressure hose from your pressure washer pump to the 3/8" FPT inlet of the trigger gun. Ensure the connection is tight and secure to prevent leaks under high pressure.
Connect Outlet Nozzle/Wand: Attach your desired spray nozzle or wand to the 1/4" FPT outlet of the trigger gun. Twist or click into place securely, depending on your accessory type.
Water Supply: Ensure your pressure washer has an adequate and continuous water supply.

5. Operating Instructions

Follow these steps for safe operation of your Landa Pressure Washer Trigger Gun:

Start Pressure Washer: Turn on your pressure washer according to its manufacturer's instructions. Allow the system to build pressure.
Engage Trigger: Aim the nozzle away from yourself and others. Squeeze the trigger to begin the flow of high-pressure water.
Safety Lock: The trigger gun features a safety lock (often a yellow lever) to prevent accidental discharge. Engage this lock when the gun is not in use or when moving the unit. Disengage it before operating.
Control Spray: Maintain a firm grip on the gun. Adjust your distance from the cleaning surface to control the intensity of the spray.
Shut Down: To stop operation, release the trigger. To completely shut down, turn off the pressure washer and release any remaining pressure in the system by squeezing the trigger until water stops flowing.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your trigger gun.

Rinse After Use: After each use, flush the trigger gun with clean water to remove any chemical residues or debris.
Inspect Connections: Regularly check the inlet and outlet connections for wear, corrosion, or damage. Replace O-rings or fittings as needed.
