Establishing a scientific cleaning procedure forms the foundation of maintenance work. Optical components require professional lens paper and cleaning fluid, gently wiping in circular motions from center to outer edges. Mechanical parts should be dusted with soft brushes, while metal surfaces need regular disinfection with anhydrous ethanol. Cleaning frequency should be adjusted according to the usage environment - high-dust environments require daily cleaning, while standard laboratories need cleaning at least twice weekly.

LED light sources require regular brightness stability checks, while traditional halogen lamps need usage time recording and timely replacement. Keep light source interfaces clean and dry to prevent oxidation affecting conductivity. Operate dimming devices gently, avoiding frequent drastic adjustments. Store backup bulbs properly to ensure quick replacement during emergencies.

Add specialized lubricant monthly to stage movement mechanisms to maintain smooth operation. Regularly inspect gear clearance in focusing mechanisms to prevent backlash. Ensure objective turret positioning accuracy, performing precision calibration when necessary. Conduct quarterly checks on all fastening screws to prevent loosening affecting stability.
