2. Safety Information
Your SANODESK EC4 is equipped with advanced safety features to ensure secure operation. Please read the following information carefully before use:

This mechanism prevents collisions between the lifting platform and objects, improving safety performance and better ensuring the safety of both the user and objects.
- Ensure the desk is placed on a level surface.
- Keep hands and fingers clear of moving parts during height adjustments.
- Do not overload the desk. The maximum load capacity is 100 kg (220 lbs).
