screws (82), four washers (88), and two lock
nuts (85). Tighten the nuts securely.
Position the main frame (2) so the two drilled
holes in the lower crossbeam (3) and the two
drilled holes in the upper crossbeam (4) are
aligned with the mating holes in the main
frame.
Secure the main frame to the lower crossbeam
using two screws (78), one spring washer (89),
four washers (88), and two lock nuts (85).
Tighten the nuts securely.
Secure the main frame to the upper crossbeam
using two screws (82), four washers (88), and
two lock nuts (85). Tighten the nuts securely.
2. Install the Leverage Arm
NOTE: Two people are required to install the
leverage arm; one to hold the leverage arm in
position, and one to install the leverage arm shaft.
