Step 3

Disconnect the laser tube grounding wire.

Step 4

• Detach the cables of the laser tube and the laser PSU.

Step 5

Remove the laser tube holders. (3mm hex screws x 4pcs)

Step 6

Place the rags or paper towels on both sides of the laser tube close to the water hoses and some on the table.

Step 7

Detach the connected water hoses at the left side of the laser tube.
The water will leak after detaching, so please prepare a water container to catch the water.

Step 8

Drain the water inside the laser tube and remove the laser tube from the machine.

• Remove the hose clip and snip off the cable tie on the water hose at the other side of the tube.
• Raise the tube and slowly detach the water hose. The water will be drained at the other side of the tube.
• Make sure the water hose on the left side is in the container.

Ensure that you attach it to the correct side with the white connector.
Please refer to the video below.

Place the new laser tube.

• The white connector will be on the left side.
• The suggested position of the tube will be that the right edge of the tube is at the center of the water pump cap.
• Ensure the water inlet of the tube is horizontal.

Step 12

Reinstall the laser tube holders.

Step 13

On the right side of the tube (Low-pressure side), connect the water hose to the tube.

Step 14

On the left side of the tube (High-pressure side), connect the water hoses together.

Connect the cables for the laser tube and the laser PSU.
After connecting, make the space as neat as possible by placing the white connector into the hole in the left corner and pushing the water hose inside the machine to make it shorter. Please refer to the video.
