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.
