If you have access to more than one lifter, it may
be helpful to change parts across lifters to help
identify any faults. For instance, if you suspect the
fault to be inside the column, exchange the col-
umn with at functional one from the other lifter to
see if the problem is xed.
If you are not able to solve the fault or problems
by yourself using this manual, please contact lo-
cal authorised service representative. If you do
not know whom to contact locally, please contact
your dealer or Etac Supply Gjøvik to get help.
