Step-by-step assembly

Step 1
Push 16 wooden dowels into the ends of four panels.
Top, bottom, fixed middle shelf and plinth — 2 dowels in each end.

Step 2
Screw 12 cam bolts into the two side panels.
6 in each side, turned in with a Phillips screwdriver.

Step 3
Stand the plinth, bottom and fixed shelf on one side panel.
Dowels and bolts go into the holes. Check which way round each panel goes (manual inset).

Step 4
Insert 4 cam locks (119081) and turn them clockwise.
In the bottom and fixed shelves, next to the side on the floor.

Step 5
Fit the top panel, then lock it with 2 cam locks.
Cam-lock holes face inwards, towards the fixed shelf.

Step 6
Lay the second side panel on top.
The dowels and cam bolts line up with the holes in the panel ends.

Step 7
Insert 6 cam locks (119081) and turn them clockwise.
Two in each panel, on the new side. Tighten them all.

Step 8
Turn the frame onto its front.
Lay it face-down so the back edges point up.

Step 9 · manual step 8
Mark the middle of the fixed shelf on both side edges.
Use a pencil — you’ll need these marks for nailing the back panel.

Step 10 · manual step 9
Unfold the back panel flat.

Step 11 · manual step 9
Slide the back panel into the grooves in the sides.
Push it in from the bottom end all the way to the top.

Step 12 · manual step 10
Draw a line across the back between the two marks.
Use a ruler — it shows where to nail into the fixed shelf.

Step 13 · manual step 11
Hammer in 18 nails (101201).
6 along the top, 6 on the line at the fixed shelf and 6 along the bottom. Keep the back edges flush (manual inset).

Step 14 · manual step 12
Stand the bookcase upright.
Get help — it is tall and heavy.

Step 15 · manual step 12
Push 16 shelf supports (131372) into the side holes.
4 per shelf, at the height you want each shelf.

Step 16 · manual step 13
Lay the 4 shelves on the supports.
Press each shelf down so it locks onto its supports.

Step 17 · manual step 14
Screw 2 wall brackets (106989) to the top panel.
Each with a screw (109041) and a washer (100832), close to the wall side.

Step 18 · manual step 14
Fix the brackets to the wall.
Wall screws and plugs are not included — use ones suited to your wall (with a washer, 100823).

Step 19 · manual step 15
Screw 6 mounting plates (109221) inside the front edges.
3 on each side, 2 screws (113287) per plate — see the manual, step 15, for the holes.

Step 20 · manual step 16
Lay the doors face down. Screw 3 hinges (109336) onto each.
2 screws (100349) per hinge, the cup in the round hole.

Step 21 · manual step 17
Clip the hinges onto the mounting plates, then tighten the screws.
Slide each hinge onto its plate until it clicks.

Step 22 · manual step 18
Fix a knob (148904) to each door.
One screw (114667) through each door from the inside.

Step 23 · manual step 19
Press on the 6 bumpers (102384), then close the doors.
3 on the back of each door, along the opening edge.
Tips & safety
- Always fix BILLY to the wall. Furniture tip-over can cause serious or fatal crushing injuries. Wall screws and plugs are not included — use ones suited to your wall.
- Doors not lined up? Turn the hinge screws with a Phillips screwdriver to move each door up/down, in/out or sideways (manual p. 21).
