Troubleshooting Diagnosis Chart
WARNING
Troubleshooting and repair procedures must be performed as specified by au- thorized service per- sonnel only. Failure to do so may result in serious bodily injury and/or property damage.
If a problem occurs with your lift, discontinue operation imme- diately! Do not attempt repairs yourself. Contact your dealer or call The Braun Corporation. One of our national service repre- sentatives will direct you to an authorized service repairman who will inspect your lift.
The cause of the problem can be determined by locating the lift function and related symptom in the Troubleshooting Diagnosis
Charts. The specific cause and remedy can then be determined by process of elimination. A Wir- ing Diagram, Electrical Sche- matic, Hydraulic Diagram and Hydraulic Schematic are provided to aid in troubleshooting.
A Repair Parts section with ex- ploded views and corresponding parts lists is also provided. Cor- rect the problem if possible. If the problem continues, contact The Braun Corporation.
