2.4 Emergency procedure 
If you or another person working on or operating the liftgate experience a dangerous 
situation: Immediately stop what you’re doing and seek expert help. 
2.5  Safety devices on the liftgate 
 
Hose rupture valves 
If a hose, pipe, or screw connection bursts, the liftgate lowers or tilts in a controlled 
manner at the permitted speed for as long as a function is being performed via one of the 
control units (control panel, handheld control, manual control box, or foot controls). Once 
the control unit is no longer being activated, the liftgate stops immediately. 
 
Safety valve 
The factory-set safety valve protects the liftgate against lifting loads that are heavier than 
the specified load-carrying capacity. This valve may be adjusted only by a qualified 
specialist using a test weight and a manometer. 
 
Fuses 
Defective fuses may only be replaced by fuses that correspond to the values specified in 
the circuit diagram and on the control unit. Larger fuses may not be triggered by 
malfunctions, which could result in cables catching fire. 
2.6 Intended use 
 
Depending on the type, the MAXON liftgate was developed for vehicles ranging from 
trucks to trailers, including semitrailers. The liftgate is used for both loading and 
unloading the vehicle and for transferring loads. Do not use the liftgate to lift any person 
other than the operator. Any other use is prohibited. 
WARNING 
 
Incorrect or improper use or handling of the liftgate or, for example, errors caused by its 
being operated by unqualified personnel can create risks for operators and bystanders 
that may result in serious or fatal injuries. 
 
IMPORTANT 
To ensure safe operation of the liftgate, read the safety instructions and 
warnings in the user manual provided.
