- To lock all drawers: Ensure all drawers are fully closed. Insert the key into the lock on the top drawer and turn it clockwise until the lock engages. Remove the key.
- To unlock all drawers: Insert the key into the lock on the top drawer and turn it counter-clockwise until the lock disengages.

Mobility and Caster Locks
The cabinet is equipped with smooth-rolling casters for easy relocation. Each standard caster includes a locking mechanism.
- To move the cabinet: Ensure all caster locks are disengaged.
- To secure the cabinet in place: Press down on the lever located on each caster to engage the lock. This prevents unintended movement.
Maintenance
- Cleaning: Wipe the cabinet surfaces with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as they may damage the rust-proof coating. Dry thoroughly after cleaning.
- Drawer Slides: Periodically check the drawer slides for any debris. If drawers become stiff, a small amount of silicone lubricant can be applied to the slides.
- Casters: Keep casters free of hair and debris to ensure smooth movement.
- Locks: Do not force the key if it feels stuck. Ensure the key is fully inserted and aligned before turning.
