C.  DRIVE SYSTEM 
 
      The drive is an electromechanical system that is powered by a non-hazardous 12 volt,  
      deep cycle, spill-proof, sealed battery.  As illustrated in Figure 23, the entire drive is 
      mounted to the Main Frame and moves with it. 
 
      Figure 23 
       

 

 
        1.  Drive Motor.  The dual direction 1.2 H.P. motor is mounted in the motor housing  
             at the bottom of the Main Frame.  When the control switch is activated, the motor 
             turns the drive screw. 
 
        2.  Overload Clutch.  Mechanical power is transferred from the motor to the drive 
             screw via a ball détente type of clutch which protects the drive screw from over- 
             running in either direction.  Over-running occurs when the operator continues 
             to apply power after the Lift Frame has reached its extreme up or down position 
             relative to the Main Frame.  At such extremes, the clutch will slip and protect the 
             drive screw.  As the clutch begins to slip, a loud warning sound (rachet) will be  
             heard.  

Immediately

 release the power switch.
