Pfaff expression 2034 Service Manual

Foreword
This service and repair manual is intended to assist you in carrying out all repairs to the machines quickly
and correctly.
Adjustments should only be carried out if you find the actual settings deviating from the requirements
described here.
When checking or adjusting a machine, please always proceed in the sequence specified. For easier
reference every workstep is marked with a dot.
Differing worksteps are marked with a circle or square.
The indications "right", "left", "top", "bottom", "front" or "rear" always refer to the upright machine with its
controls facing the operator.
When assembling dismantled machines, make approximate adjustments right in the course of work. This
facilitates subsequent precise adjustments.
If not specified otherwise, the handwheel must always be turned to the front.
Always pull out the mains plug before making repairs to live parts or in their vicinity. An electrical safety
test must be carried out after every repair, including mechanical ones. According to the German law on
safe machine operation of June 24, 1958, VDE regulations apply as official rules in electrical engineering
and as such are basic to electrical safety tests of technical devices.
The required electrical tests for appliances are set forth in Para. 4 of the Regulations for Repair,
Modification and Testing of Used Electrical Devices (VDE 0701, edition 05.93). After every repair of elec-
trical devices we manufacture, a test in accordance with VDE 0701 is obligatory.
Outside Germany, there are similar regulations in force, which are largely identical with the requirements
of VDE 0701. For repairs of electrical devices, it is therefore by all means necessary to consult an expert.
