Package Contents
The DEVAISE 3-Drawer Mobile File Cabinet comes fully assembled, with the exception of the casters. Please verify that all components are present:
- 1 x DEVAISE 3-Drawer Mobile File Cabinet (Main Unit)
- 5 x Casters (4 swivel with brakes, 1 anti-tip)
- 2 x Keys for the locking mechanism
- 1 x Removable Hanging Bar for file drawer

Setup: Caster Installation
Your file cabinet is mostly assembled. Only the casters require attachment.
- Prepare the Cabinet: Carefully lay the cabinet on its side or back on a soft, clean surface to avoid scratching the finish. Ensure the bottom is accessible.
- Identify Casters: You will have four swivel casters (two with locking brakes) and one auxiliary anti-tip caster.
- Install Swivel Casters: Insert the stems of the four swivel casters into the designated holes at each corner of the cabinet's base. Twist clockwise until they are securely tightened. Ensure the two casters with brakes are installed on the front side of the cabinet for easy access.
- Install Anti-Tip Caster: Locate the central hole at the front underside of the bottom drawer. Insert the stem of the auxiliary anti-tip caster into this hole and twist clockwise until secure. This caster provides stability when the bottom drawer is fully extended.
- Upright the Cabinet: Carefully return the cabinet to its upright position.

Operating Instructions
Drawer Operation
The drawers feature full-extension slides, allowing them to open completely for easy access to contents. To open a drawer, gently pull the hidden handle located at the top edge of each drawer. To close, push the drawer firmly until it is fully seated.

Mobility and Stability
The cabinet is equipped with five casters for easy mobility. Two of the front casters have locking brakes. To move the cabinet, unlock the casters. To keep the cabinet stationary, engage the brakes on the front casters. The central anti-tip caster provides additional stability when the bottom drawer is open.

Maintenance
- Cleaning: Wipe the cabinet surfaces with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that may damage the finish.
- Casters: Periodically check casters for debris or hair that may impede movement. Clean as necessary.
- Drawer Slides: If drawers do not slide smoothly, a small amount of silicone-based lubricant can be applied to the slides.
