Manual Lowering

Each Manual Lowering Valve (Figure 3-6) is

equipped with a plunger, found at the base of the lift

cylinders and on the back side of the jib boom

(Figure 3-7). Use the plungers to lower the platform

in case of a complete electrical power failure, a load

shift, or other emergency situation. To lower the

work platform, push the valve plungers. Continue

pushing the plungers to completely lower the booms.
