IMPORTANT: To maintain the robot's IP65 rating, use care when reassembling
the robot's cover.
1. Before installing the cover, check the cover O-ring around the inner groove of the cover
to make sure that it is in place and not crimped.
2. Remove all power and any air supply from the robot.
3. Hold the cover over the outer link and check to see that the clamp nuts attached to the 8
side screws are positioned so they will slip into place when the cover is lowered down
onto the outer link.
4. Slowly lower the cover down onto the outer link, making sure that the O-ring does not
fall out or get pinched as the cover presses down to make the seal.
5. Reinstall the two screws and nylon washers at the top of the outer link and tighten to
0.56 N-m.
6. Reinstall the two screws (check for O-ring on screw) near the front of the outer link and
tighten to 1.1 N-m.
7. Tighten the 8 side screws to 1.1 N-m. Be careful to not over-tighten. Begin with the two
screws at the back of the outer link (one on each side), then move forward to the next
two until you have tightened all eight. We recommend this pattern to achieve a bal-
anced secure fit around the cover.
8. Reinstall the collar nut and tighten until secure.
9. Turn on the compressed air supply to the system before restarting the robot.

NOTE: As you lower the cover down onto the outer link, push the 8 side
screws all the way in, so the clamp nuts will slide into the correct pos-
ition.
