1. Open the gripper to an intermediate position, so you do not hide the six (6) M4 screws holding the rack housing in place.
2. Remove the gripper from its coupling using the 4 mm hex key to unscrew the four (4) M5-0.8 x 25mm screws. Note that each
screw uses a tooth lock washer, do not lose them.
3. Remove the six (6) M4 screws holding the rack housing.
4. Gently pull the rack housing away from the body of the gripper.
5. The finger's racks will slide off freely from the rack housing. Clean the rack housing, the racks and the pinion using a
degreaser. Dry thoroughly. Clean the fingers (finger holders and fingertips if that is the case) with a dry towel. Remove all
debris, dirt and dust
6. Clean the coupling with a dry towel, pay particular attention to the electrical contact.
7. Clean the gripper according to the procedure described in the Gripper cleaning section.
8. Visually inspect the gripper and pay attention to any visible damage.

Info
