Maintenance
The ROBOTIME Marble Run Lift Coaster requires minimal maintenance to ensure smooth operation and longevity.
General Care:
- Keep the model clean and free from dust. Use a soft, dry cloth to gently wipe surfaces.
- Avoid exposing the model to direct sunlight, extreme temperatures, or high humidity, as this can cause the wood to warp or crack.
- Do not use water or chemical cleaners on the wooden parts.
Lubrication (Optional):
If the gears or moving parts become stiff over time, a small amount of paraffin wax or a dry lubricant (like graphite powder) can be applied to contact points to improve smoothness. Avoid using oil-based lubricants, as they can attract dust and damage the wood.
