Step-by-step assembly

Step 1
Screw 4 cam bolts (118331) into the two posts.
Two in each post, by hand. You build two side frames — this is the first.

Step 2
Push 4 dowels (101345) into 2 rails and press them onto a post.
Use the thin 101345 dowels, not 101350.

Step 3
Push 12 dowels (101345) into the other 3 rails, then add the second post.
Two dowels in each end of these rails.

Step 4
Insert 4 cam locks (120076) and turn them clockwise.
Use the flat-head screwdriver.

Step 5
Screw 2 feet (107862) into the bottom ends of the posts.

Step 6 · manual step 1–5
Build the second side frame the same way.
4 cam bolts, 16 dowels, 4 cam locks and 2 feet.

Step 7 · manual step 6
Push 8 dowels (101350) into 2 shelves.
The thick 101350 dowels go into the 2 shelves without screw holes — see the manual, step 6.

Step 8 · manual step 7
Stand a side frame on its edge and press the 2 shelves in.
They go into the 2nd and 4th places.

Step 9 · manual step 8
Push 12 dowels (101345) into the other 3 shelves.

Step 10 · manual step 9
Fit the 3 shelves and fix them with 6 screws (110727).
Screw through the posts with the Allen key.

Step 11 · manual step 10
Fit the second side frame and fix it with 6 screws (110727).

Step 12
Carefully stand the shelf unit upright.

Step 13 · manual step 11
Place it against the wall and mark under the top shelf.
Mark the wall with a pencil at the underside of the top back rail.

Step 14 · manual step 12
Fix the strap (128481) to the wall at the mark.
Wall screws and plugs are not included — use ones suited to your wall.

Step 15 · manual step 13
Screw the strap to the top back rail with the washer and screw.
Push the unit back first. Use the Phillips screwdriver.
Tips & safety
- Always fix MUSKAN to the wall. Furniture tip-over can cause serious or fatal crushing injuries. Wall screws and plugs are not included.
- Heaviest things on the lowest shelves. Never let children climb or hang on the shelves, and never put a TV on the unit.
