How to Dismantle Pneumatic Cylinder?

Step 1: Disassemble the wheels from the claw base.

Step 2: Stand on the claw base to make it stable, then hold the armrests and shake the chair leftward and rightward while lifting the seat up. Repeat 5-6 times until the pneumatic cylinder and the base come off the seat.

Step 3: Turn over the claw base. Use a hammer (preferably a rubber hammer) to tap on the center of the base to loosen and disassemble the air cylinder from the base.

NOTE: We recommend applying edible oil/engine oil/rust inhibitor to the connection between the air cylinder and the claw base for lubricating.
