INSTALLING THE
COUNTER-
WEIGHTS

Have an assistant raise the bending apron to the horizontal position, and hold it in
that position while the counterweights are installed.

Install a counterweight in the mounting hole in each end of the bending apron.
Adjust the counterweights so that they balance the bending aparon in the
horizontal position.

Tighten two set screws securely on each counterweight shaft.

WARNING

THE COUNTERWEIGHTS ARE HEAVY

Use care when installing the counterweights to avoid injury. Be sure the set screws

are tightened enough so the counterweights will not drop when the bending apron is

returned to the vertical position.
