the elevating assembly.
Stand clear of the elevating assembly while operat-
ing the emergency lowering valve knob.
The emergency lowering valve can be reached only
from the ground. When needed to be open to lower
the platform, ask for assistance from the ground. The
valve is located at the rear of the machine as shown in
Figure 9.
1. Pull the knob to open the valve.
2. To close the valve, release the knob.
NOTE: The platform will not elevate if the emergen-
cy lowering valve is open.
AC UNITS ONLY
In the event of a mains power failure, the platform can
be lowered from the platform controls by operating the
emergency lower switch, the enable button and the
platform lower button at the same time.
NOTE: This procedure should only be used in the event of an emergency.
