Please read and understand all safety instructions before assembling or using the file cabinet. Failure to follow these instructions may result in injury or damage to the product.
- Always assemble the cabinet on a flat, stable surface.
- Use appropriate safety gear when lifting and moving the cabinet due to its heavy weight.
- Do not overload the cabinet beyond its 440 lbs total capacity.
- Keep the cabinet away from heat sources.

The FOSTOKO 4-Drawer Lateral File Cabinet requires assembly. Each part is labeled with a code, and clear instructions are included in the package. It is recommended to assemble the cabinet on a soft, clean surface to prevent scratches.
General Assembly Steps:
- Unpack and Identify Parts: Carefully remove all components from the packaging. Verify that all parts listed in the package contents are present. Refer to the included diagram for part identification.
- Assemble the Cabinet Frame: Attach the side panels to the bottom panel, followed by the back panel and top panel, using the provided hardware. Ensure all connections are secure.
- Install Drawer Slides: Attach the drawer slides to the inside of the cabinet frame according to the instructions. Ensure they are level and aligned.
- Assemble Drawers:
- Attach the drawer fronts to the side panels of each drawer.
- For the drawer backs, ensure the larger flange is facing down and towards the back/wall, then push firmly to lock into place from the inside out.
- Attach the drawer bottoms.
- Install the drawer portion of the slides onto each assembled drawer.

Anti-Tilt System:
- For safety, the cabinet is equipped with an anti-tilt system that allows only one drawer to be opened at a time.
- Do not attempt to open a second drawer while another is already extended, as this will engage the safety mechanism and prevent further opening.
6. Maintenance
Regular maintenance will help preserve the appearance and functionality of your file cabinet.
- Cleaning: Wipe the cabinet surfaces with a soft, damp cloth. For stubborn marks, a mild soap solution can be used, followed by drying with a clean cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the powder-coated finish.
- Drawer Slides: Periodically check the drawer slides for any debris or dust. If necessary, clean them with a dry cloth. Lubrication is generally not required for ball-bearing slides but can be applied sparingly if movement becomes stiff.
- Hardware: Occasionally check all screws and fasteners to ensure they remain tight. Retighten if necessary.
- Rust Prevention: The cold-rolled steel construction with powder coating is designed to resist rust. Keep the cabinet in a dry environment to further prevent corrosion.
