SECTION 7—OPERATION

The control handle MUST be in the open position (control valve positioned away from 
pump handle) to lower the boom and the patient. The rate of descent can be controlled by 
varying the amount that the control valve is opened.
NOTE: A safety gate is part of the hydraulic system that maintains a SLOW constant descent of 
the boom regardless of how far the control valve is opened.
