Troubleshooting and
repair procedures
must be performed
as speci
fi
ed 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 Product Support
representatives 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 speci
fi
c cause and
remedy can then be determined
by process of elimination. A Wir-
ing Schematic, Hydraulic Dia-
gram and Hydraulic Schematic
are provided to aid in trouble-
shooting.
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.
