WARNING
Troubleshooting and 
repair procedures 
must be performed 
as specified by an 
authorized service 
technician only.  
Failure to do so may 
result  in serious 
bodily injury and/or 
property damage.
If a problem occurs with your 
ramp, discontinue operation 
immediately!  Contact your sales 
representative or call The Braun 
Corporation at -800-THE LIFT
®
.  
One of our national Product Sup-
port representatives will direct you 
to an authorized service techni-
cian who will inspect your ramp.  
The cause of the problem can 
be determined by locating the lift 
function and related symptom in 
the Troubleshooting Diagnosis 
Chart.  The specific cause and 
remedy can then be determined 
by process of elimination.  A 
Wiring Diagram and Electrical 
Schematic are provided to aid in 
troubleshooting. 
A Repair Parts section with an 
exploded view and corresponding 
parts list is also provided. Correct 
the problem if possible.  If the 
problem continues, contact The
