Emergency Lowering
The main boom can be lowered in an emergency using
the emergency lowering knob at the base of the lift cylin-
der. The emergency lowering knob allows the main
boom to be lowered only. Only use this method if the en-
gine will not start and the emergency power system will
not work.
Pinch points exist between boom components and
between the booms and turntable. Death or serious
injury can result if the booms or platform lowers
onto personnel. Make sure all personnel stand clear
while lowering the booms.
Use the following procedure to manually lower the main
boom.
1. Slowly turn the knob (refer to Figure 10.5) to open
the bleed down valve. Control the rate of descent by
turning the knob.
