Understanding the Gear Locking System
The gear locking system of the tilt/rocking base is made up of the locking key (a), the drive
gear (b), and the locking paddles (c).
When locking key is turned, the drive gear rotates and forces the locking paddles to move in
and out.
When the locking paddles are in the chair lock position (figure 2), the locking key (a) will
move down and lock itself into place. This is to prevent the locking paddles from becoming
inadvertently moved out of the chair lock position.
In order to return the paddles to the chair release position, lift the locking key (a) up
approximately ½” before turning it.
