Installation and commissioning
8 Installation and commissioning

The machine must only be mounted and commissioned by qualified personnel!
All relevant safety regulations are to be observed!
If the machine is delivered without a table, it must be ensured that the frame
and the table top which you intend to use can hold the weight of the machine
and the motor. It must be ensured that the supporting structure is sufficiently
sturdy, including during all sewing operations.
8.01 Installation
The site where the machine is installed must be provided with suitable connections for the
electric current, see Chapter 3 Specifications.
It must also be ensured that the standing surface of the machine site is firm and horizontal,
and that sufficient lighting is provided.
The method of packaging used requires that the table top be lowered for trans-
port. The following is a description of how to adjust the height of the table top.
8.01.01 Adjusting the table-top height

Care and maintenance
10 Care and maintenance

10.01 Servicing and maintenance intervals
Clean ................................................................. daily, more often if in continuous operation
Check oil level ..........................................................................................................monthly
Oil the trimmer -731/01 ........................once a week, more often if in continuous operation
These maintenance intervals are calculated for the average running time of a
single shift operation. If the machine is operated more than this, shorter inter-
vals are recommended.
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 ope-
ration:
● Swing out the cover plate and tilt back
the sewing head.
● Clean the hook and hook compartment
daily, more often if in continuous opera-
tion.
Return the machine to its up-

right position using both hands!
Danger of injury by crushing
between the edge of the
machine and the table top!
Fig. 10 - 01

10.03 Topping up the oil tank

The oil reservoir must always
1 have oil in it.
● Whenever it is necessary to refill the re-

servoir, tilt back the machine and let it
rest on the sewing head support.
● Fill oil through hole 1 into the reservoir 2
up to the level of the front edge (see ar-
row).
Use both hands to set the sew-

ing head upright!
Danger of crushing between the
sewing head and the table top!
2
Only use oil with a mean vis-
cosity of 22.0 mm2/s at 40°C
Fig. 10- 02 and a density of 0.865 g/cm3 at
15°C.
We recommend PFAFF sewing machine oil, part no. 280-1-120 144.
10.04 Oiling the edge trimmer -731/01

● Once a week pour oil on oil sponge 1
through hole 2.
● Lubricate the guides 3 and 4 once a
week.
2 Only use oil with a mean vis-

cosity of 22.0 mm2/s at 40°C
1 and a density of 0.865 g/cm3 at
15°C.
We recommend
PFAFF sewing machine oil,
