Foreword
The purpose of this service manual is to assist you in quick and correct repairing of the machines.
Adjustments should only be made if the settings deviate from the requirements described herein.
When checking or adjusting a machine, always proceed in the order of the worksteps prescribed.
For easier reference every workstep is marked with a dot.
Differing worksteps are marked with a circle or square.
The indications “left”, “right”, “top”, “bottom”, “front” and “back” always refer to the upright machine with
the controls facing the operator.
When assembling dismantled machines, adjust the machine to approximately the right settings.
This facilitates the subsequent fine adjustments.
Unless otherwise specified, the handwheel must always be turned forward.
When carrying out maintenance work on live parts or in their proximity, the machine is to be separated
from the power supply by unplugging the lead cord from the electrical socket.
An electrical safety test must be carried out after all repair work, even if the repair work is of a mechanical
nature.
According to the German law on safe machine operation of June 24, 1958, VDE regulations are the
recognized rules in the field of electrical engineering and form the basis for electrical safety tests of
technical appliances.
The required electrical tests for the appliances are laid down in paragraph 4 of the regulations for repair,
modification and testing of electrical appliances
(VDE 0701, edition 05.93).
It is obligatory to test our electrical appliances according to VDE 0701 following any repairs to our
electrical appliances.
Outside Germany there are similar regulations in force which are largely identical with the requirements
of VDE 0701.
It is therefore necessary to consult a specialist when carrying out repairs on electrical appliances.
For the proper adjustment of the machine, the following gauges and tools are required:
