Maintenance & Troubleshooting

This section contains maintenance and troubleshooting information for your v30 laser.

Maintenance

The Maintenance section includes subsections:

•

Disabling the v30 laser

•

Daily inspections

•

Storage/shipping

•

Cleaning optical components

Disabling the v30 laser

Before performing any maintenance on your OEM v30 laser, be sure to completely disable the laser by
disconnecting DC power from the laser.

Daily inspections

1

For water-cooled lasers, inspect cooling tubing connections for signs of leakage. Check for signs
of condensation that may indicate the cooling water temperature is set below the dew point
temperature. Condensation will damage electrical and optical components inside the laser. See
Setting coolant temperature in the Getting Started chapter for details on preventing
condensation.

2

When using compressed air as a purge/assist gas for your beam delivery system, empty water
traps and oil separators on each filter and/or dryer between the laser and your compressed air
source. Compressed air must meet the gas purity specifications shown in the Technical Reference
chapter.

3

Inspect beam delivery components for signs of dust or debris and clean as required. When
cleaning the optical surfaces of beam delivery components, carefully follow the manufacturer’s
instructions.

4

Visually inspect the exterior housing of the laser to ensure that all warning labels are present.
Refer to Figure 1 in the Laser Safety chapter for label types and locations.
