How to correctly reinstall the high-pressure lance on the MAKITA HW132 pressure washer?

Question

Accepted Answer

Your MAKITA HW132 pressure washer uses a high-pressure connection system designed to withstand 130 bars. If the high-pressure hose has come off, here is the precise procedure to reinstall it correctly.

Before any intervention: Turn off the device and unplug it from the electrical outlet. This is a requirement according to the manual. Close the water tap and pull the trigger on the gun to release any residual pressure from the system until water stops coming out of the nozzle.

Inspection of parts: Carefully examine the high-pressure hose and the spray head connection. Check for any cracks, tears, or dirt residues that could prevent a proper seal. Gently clean the contact surfaces with a dry cloth. The internal sealing rings of the connection must not be damaged.

Correct reinstallation: Align the hose with the connection of the head. Firmly push the hose into the connection straight until you feel or hear a distinct click indicating that the attachment is secure. Depending on the model of the head, there may be a locking system to turn to permanently secure the connection. Ensure that the hose is well-centered and does not have an angle that could weaken the connection.

Checking the attachment: Before filling the tank or starting the device, pull firmly but gently on the hose several times to ensure that it cannot come off. The connection must be extremely solid and should not move at all.

If after these steps the hose continues to come off regularly, it means that the locking mechanism or the sealing rings are worn. In this case, contact an authorized MAKITA technical assistance center to have the worn parts replaced, as you cannot maintain a pressure of 130 bars with a faulty connection.
