2. Rotate the cover counterclockwise exposing the square end of the cart
screw.
3. Insert the speed wrench and push toward rear of cabinet.
The wrench must be pushed toward rear of cabinet to unlock the cart
raking screw. The pressure must be maintained for the entire cart
insertion/withdraw operation.
4. If cart is in test/withdrawn position, rotate the speed wrench clockwise
to insert the cart ( Figure 8
). From test to service position requires
11 complete rotations (a mechanism stops the screw rotation after
11 turns). The last turns require more torque to overcome the cart
engagement resistance.
