3. Disconnect the rods of the first rod pair from the balls as follows:
Hold the front unit firmly in one hand and pull the first rod from the ball with your other hand. The
pretension of the springs means that a relatively high amount of force is needed to separate the
joints
2
(
Fig. 6.4). The spring forces between the rods can cause the partially disconnected pair
of rods to cross over. Keep holding the front unit firmly in one hand and pull the second rod from the
ball.
4. Place the front unit in a position which allows you to disconnect the other two pairs of rods from the
front unit.
5. Disconnect the second and third pair of rods and remove the front unit.
