  Decommissioning, disassembly, and disposal 
 
After decommissioning, secure power-operated and power-assisted liftgates against 
unauthorized use (see Section 5.6 Emergency! Platform moved by mechanical means).  
Be particularly careful when removing the solenoid valves (safety valves). Before 
unscrewing the solenoid valves, make sure the platform is secured against sudden 
lowering and opening, e.g. using ropes, straps, or chains. 
 
 DANGER 
 
Danger! Serious risk of death or injury! 
When the liftgate is unsecured and the safety devices (e.g. solenoid valves) are out of 
order, the operator can lose control of the liftgate. Under these circumstances, the 
careless and/or incorrect opening and lowering of the liftgate could result in serious injury 
or death due to the liftgate free-falling to the ground. 
The platform must be secured against opening using ropes, straps, or chains. 
The platform may be opened only with the aid of a crane or forklift. 
 
When disposing of the liftgate, the hydraulic system (lifting and closing cylinders, 
reservoir, hydraulic pump, solenoid valves, cables, high-pressure hoses, etc.) must be 
completely drained of fluid. Components lubricated with oil and grease must be cleaned 
using a pressure washer before disposal. 
Dispose of hydraulic fluid in accordance with local regulations, especially those related to 
environmental protection, e.g. at a recycling center or specialized dealer. 
 
Remove and dispose of electrical components and cables in accordance with local 
regulations. 
 
Remove plastic and elastomer components and dispose of separately in accordance with 
local regulations. 
 
 WARNING 
 
Decommissioning may be hazardous if the liftgate could not be shut down under optimal 
conditions. Malfunctioning control elements can cause injury. Be sure to perform regular 
inspections (maintenance schedule) of the control elements. 
 
 WARNING 
 
Decommissioning may be hazardous if the liftgate could not be shut down under optimal 
conditions. A missing or non-functional emergency stop button can result in injury.
