Adjusting the lift” on page 14).

Dismount the arm.

Lay the arm upside-down on the work bench.

The elbow gas spring is between the arm segments. Make a note of where the
screw posts are inserted into the end blocks relative to the hinge pins.

•

When the arm is deployed, the screw posts are on the outside of the curve.

With the C-clamp, squeeze the ends of the elbow gas spring (nearer the tool) to take
tension off the screw posts.

Remove the screws holding the gas spring in place:
a.

With the Allen wrench, loosen one of the screws.

Note the placement of the washers.

Remove the screw.

Repeat for the other screw and remove the gas spring.

With the open-end wrench, remove the screw posts.

With the C-clamp, squeeze the ends of the shoulder gas spring (nearer the mount-
ing interface block) enough to take tension off the screw posts.

Remove the screws holding the gas spring in place:
a.

With the Allen wrench, loosen one of the screws.

Note the placement of the washers.

Remove the screw.

Repeat for the other screw and remove the gas spring.

10.

With the open-end wrench, remove the screw post from the proximal link.

11.

With the Allen wrench, remove the screw holding the shoulder mount to the
shoulder hinge block.

12.

Remove the shoulder mount from the hinge block. You may need a mallet.

13.

If you are reusing the parts in a handedness conversion:
a.

Remove the screw (or wedge) post from the shoulder mount.

Align the threads of the screw post carefully, since they are easily cross-
threaded and install it on the other side.

Or press the wedge post into the socket on the other side of the shoulder
mount. You may need to use the C-clamp.
