Side Adjustment
When you assemble your Footrest, and tighten all 8 screws firmly, the sides should be straight up and down. Do not over-tighten the screws. Attempting to further tighten the screws when they are already firm can cause damage.
Usually, tightening the 4 “wide apart” screws on the permanent shelf VERY firmly will keep the sides straight, and nothing more is needed. Try this first.
But wood can flex and bow slightly after production. It is possible for the sides to be slightly farther apart up by the handles, compared to the lowest slots.
In an extreme case, the shelf may not rest firmly in the top couple slots, and can fall down on one side.
If that happens, here is a simple adjustment to bring the handles back in together permanently:
1) Turn the assembled Footrest upside down, resting on the handle area of the sides.
2) Loosen all 8 screws with the hex wrench until the sides wobble, and seem “loose.”
3) Take two of the black/yellow foam footpads, and trim one thin slice off the end of each one.
4) Slip one slice of foam on each side, between the support crossbar, and the sides. If you can’t slip it in easily, loosen the screws on that side a little more. They will fit between the 2 crossbar screws.
5) Slide the foam down, so most of it is out of sight. Once in place, snug the 2 crossbar screws. Do both sides. Don’t crank on them, just snug them down. (They are the 2 screws very close together.)
6) Now re-tighten the 2 screws holding the permanent shelf. (They are the screws very far apart.) Do not try to tighten them past firmly tight.
7) Then snug the 2 crossbar screws again more firmly.
8) When you have done this on both sides, you will have angled the sides inward just slightly up by the handles, and created a tighter fit for the movable shelf at the upper slots.
9) If you find the handles are now too close together for the shelf to slide easily in the top slot, you can simply remove a foam shim from one side, to reduce the angle.
10) Keep the hex wrench handy, since wiggly feet can loosen screws over time. If you like, a drop of “blue” Loctite on the threads will keep the screws from loosening, while still allowing dis-assembly in the future. (“Red” Loctite is permanent, and is not recommended.)
