Maintenance Guide for Handheld Fiber Laser Cleaning Machines

Proper maintenance is essential for ensuring the stable performance, long service life, and high cleaning efficiency of any handheld laser cleaning machine. Whether you are using a continuous laser cleaning machine, or  pulse laser rust remover, following a professional maintenance routine can prevent unnecessary downtime, protect core optical components, and maintain cleaning quality.

To avoid personal injury or equipment damage, all maintenance operations should be performed by trained professionals. 

Maintenance of the Handheld Laser Cleaning Head

The handheld cleaning head is the most frequently used part of a fiber cleaning machine, and it directly affects the cleaning result. Routine inspection helps prevent issues such as lens burning, weak cleaning, or beam distortion.

1. Daily Inspection

  • Check the protective lens before every use.
  • If dust, oil, or foreign particles are found, clean the lens with a dust-free cotton swab dipped in industrial alcohol.
  • If there is coating wear, scratches, or visible damage, replace the protective lens immediately. 
  • A clean lens ensures stable power output and prevents damage to internal optical components.

2. Regular Inspection

  • If the fiber laser cleaner has been idle for a while, inspect the internal optical module before powering on.
  • Ensure all optical components are free from dust, mold, moisture, or abnormalities. 
  • This avoids beam instability and protects the expensive core components.

3. Checking the Laser Spot

  • Use black image paper to regularly observe the laser output spot.
  • If the spot appears uneven, distorted, or misaligned, arrange for repair or recalibration immediately. 
  • This ensures consistent, high-efficiency cleaning.

Maintenance of the Water Chiller for Fiber Laser Cleaning Machines

The water chiller ensures safe temperature control for the 1500W / 2000W / 3000W continuous fiber laser cleaning machines. Proper cooling prevents overheating, optical module failure, and beam attenuation.

1. Clean the Condenser & Dust Filter

Dust accumulation reduces cooling efficiency. Clean these components periodically to maintain optimal heat dissipation.

2. Drain Coolant When Necessary

If the machine will be transported or unused for a long period, drain the coolant to prevent contamination or blockage.

3. Winter / Low-Temperature Precautions

When ambient temperature drops below 2°C:

Ensure the chiller is functioning before starting the machine.

Frozen coolant can damage the laser source, output head, or water chiller. 

This step is critical for users in cold climates.

4. When to Replace Coolant

Replace coolant if:

It appears cloudy or discolored

The machine has been idle for a long time

There are signs of contamination or reduced cooling performance

Using clean, high-quality coolant improves laser stability and extends the lifetime of the equipment.
