What you need

Step 1

              Remove the screws on one Side
  • Remove the two screws on one side of the armchair, at the ends of the armrest using the T25 screwdriver
  • The upper screw is a short one
  • The lower screw is a long one

Step 2

              Removing the armrest
  • Loosen the top side of the armrest, so it can move if necessary
  • With a decent amount of force, pull the armrest parallel to the screws.
  • The armrest should slide down of the two axis (where the screws where)
  • The lower axis is that holds the armrest mostly in place, so to prevent braking the plastic armrest, apply the force as close to the bottom screws axis as possible!

Step 3

              Removing the armrest on the other side
  • Remove the two screws from the other side of the chair (on the other, remaining armrest)
  • Remove the armrest similarly to the other side, along the screw axis
  • This side can be slid off easily, since the bottom axis will come out with the armrest
  • Mind the two circular plastic washers on the lower axes
  • Mind the two plastic inner washers (that are parallel to the axes
  • The second (parallel) washer on the side, where the first armrest was before, can be removed by pulling the shaft out a little, and then pushing it back (slightly tilted), thus pushing the plastic washer out
  • Finally, the shaft may be removed from the other armrest as well, however, it can be stuck sometimes (you could possibly use a plier, but it can damage the shaft’s surface)

To reassemble your device, follow these instructions in reverse order.

Love this guide, its fantastic! Not many places on the internet that reference repair or disassembly of the Wilkhahn FS line chairs. You sir are a brilliant person.

Side note, does anyone know how to replace/dissemble the gas strut/lift for this Wilkhahn FS line chair?

my FS 211/8 is from the mid-1980s, newer models have different levers to adjust the resistance of the syncro mechanism.

0 get a replacement gas strut

1 pull the seat to the highest position and turn chair upside down

2 remove the plastic covers at the bottom of the column and around the levers under the seat with a screwdriver.

3 at floor end of column: slide retaining clip off the plunger with a flat blade screw driver. plunger will drop into column.

4 lift / remove entire wheel assembly with the column. do not lose bearing, washers and rubber end stop inside column.

5 remove hex nut connecting the up/down lever to the gas strut (under seat).

6 remove gas strut from seat. it is only pushed into the seat and held by friction. it’s a TIGHT fit. use water pump pliers, grip firm. losen strut from seat with small cw/ccw movements. eventually it will come off.

7 put replacement gas strut into place. pushi it into seat FIRMLY. reassemble in reverse order.
