LCD-segments and the horn automatically for a short time during the power-on phase, after
which the lettering PFAFF appears on the display, until the higher-ranking control unit sends
commands to the control panel.
The function keys are located around the display 1. They are foil-packed without permanent
marking and without contact signal. Fixed functions are allocated to the keys, see Chapter

Each time a key is pressed, this must be confirmed by at least one beep tone. Irrespective
of the machine mode a double beep signal is given if invalid keys are pressed or maximum
values reached.
If a corresponding value has to be set for the activated function, this is carried out with the
corresponding +/- key. By pressing and holding the corresponding +/- key, the relevant
numerical value 4 is changed slowly to begin with. If the corresponding +/- key is held down
longer, the values change more quickly.

Installation and commissioning
8 Installation and commissioning
The machine must only be installed and commissioned by qualified personnel!
All relevant safety regulations must be strictly adhered to!
If the machine is delivered without a table, be sure to use a stand and table top
that can hold the weight of the machine with its motor.
It is very important to ensure that the stand of the machine is firm and steady,
also during sewing.
8.01 Installation
The site where the machine is installed must be provided with suitable connections for
electric current.
It must be ensured that the standing surface of the machine site is firm and horizontal, and
that sufficient lighting is provided for.
For packing and transportation reasons the table top is in the lowered position.
The table height is adjusted as described below.

Installation and commissioning
8.02 Commissioning
Before commissioning the machine, clean it thoroughly, fill the oil pan with oil
and adjust the oil level, see Chapter 10 Care and Maintenance!
● Examine the machine, in particular the electric cables, for any damage.
Have qualified personnel check whether the machine can be operated with the
available voltage and whether it is connected properly. If there are any
irregularities do not operate the machine!
The machine may only be connected to an earthed socket!
When commissioning the machine or after a long period of non-operation,
operate the machine with max. 2000 spm for the first 10 minutes! Danger of
damage to the machine!
● When the machine is running, the balance wheel must turn towards the operator. If this
is not the case, have the motor adjusted by qualified personnel, see the motor operating
instructions.

10 Care and maintenance
10.01 Maintenance intervals
Clean the entire machine .............................................................................. once a week
Clean the hook compartment .................... once a day, or more often if in continuous use
Oil the machine ............................................................................................. once a week
Oil the hook race ................ when commissioning the machine and after long downtimes
Oil the head parts (felt) ....... when commissioning the machine and after long downtimes
During all cleaning work the machine must be disconnected from the power
supply by switching off the main switch or pulling out the plug!
Danger of injury if the machine is started accidentally!
Care and maintenance
10.02 Cleaning the machine
The cleaning cycle required for the machine depends on following factors:
● Single or several shift operation
● Amount of dust resulting from the workpiece
It is therefore only possible to stipulate the best possible cleaning instructions for each indi-
vidual case.
For all cleaning work the machine must be disconnected from the mains by
switching off the on/off switch or by removing the mains plug!
Danger of injury if the machine suddenly starts up .
To avoid breakdowns, the following cleaning work is recommended for single shift operation:
● Clean hook compartment and needle area of sewing head several times daily.
● Clean the entire machine at least once a week.
