of the brake lever.
2. Operate the brake release on one
drive unit and, depending on the
distance between the centres of the
masts, allow the unit to descend.
Distance between centres 730 cm /
24 ft : 25,5 cm / 10.0 in lower.
Distance between centres 1330 cm /
43.6 ft: 46 cm / 18.1 in lower.
These distances represent a platform
slope of 2 degrees.
3. Operate the "UP" push-button on the
platform. The lowest unit must now be
the first to rise.
4. Repeat the previous steps for the
other unit.
