The unit is equipped with a device that prevents more than one drawer or shelf from being extended at any one time. Do not try to override or disconnect this device as the file may tip.
When the files are used side by side, or back to back, it is recommended that they be fastened together (ganging) and if used against a wall, that they be anchored to the wall.
When loading the empty cabinet with filing material, do so by evenly distributing the material among all openings, staring with the bottom openings first. Fully loading the top opening first, and then extending it, may cause the file to tip.
