Were to fill laser gearbox oil?

The location to fill laser gearbox oil depends entirely on the specific make and model of the laser system. There's no universal answer. Laser systems, especially those with moving parts requiring gearboxes, have varying designs.

To find the oil fill point, you should:

1. Consult the laser system's manual: This is the most reliable source of information. The manual will have diagrams and instructions specifically for your model.

2. Look for fill plugs or dipsticks: These are common features on gearboxes. They might be located on the side, top, or bottom of the gearbox housing. They often have markings or are easily identifiable as access points.

3. Check for labels near the gearbox: Manufacturers sometimes label the fill point directly on the gearbox or the surrounding casing.

4. Contact the manufacturer or a qualified service technician: If you can't locate the fill point yourself, contacting the manufacturer or a technician specializing in laser systems is the best course of action. Improperly filling the gearbox could damage the equipment.

Important Safety Note: Working with laser systems requires caution. Never attempt to service a laser system unless you are properly trained and understand the potential hazards. Improper maintenance could lead to injury or equipment damage.
