8 Mounting and commissioning the machine

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, be sure 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, even
during sewing operations.

8.01 Mounting

The necessary electricity supply must be available at the machine’s location. Also, a stable
and horizontal surface as well as adequate lighting are required at the location.

Depending on the type of table, the method of packaging used may require
that the table top be lowered for transport. The following is a description of
how to adjust the height of the table top.

8.01.01 Adjusting the table-top height

● Loosen screws 1 and 2 and set the desired table-top height

● Tighten screws 1 well.

● Adjust the pedal to the desired position and tighten screw 2.

● Loosen nuts 1.

● Tighten the V-belt with belt take-up

hanger 2.

● Tighten nuts 1.

A quick motor is shown in
Fig. 8-02. If another motor is
used, carry out this step
according to the instructions in
the motor instruction manual.

Fig. 8 - 02

8.01.03 Mounting the upper V-belt guard

This step is eliminated for integrated sewing motors.

● Break out the belt guard case 1 at the
points marked by the arrows.

● Fasten belt guard 2 in holes 3.

● Attach belt guard 4 to the machine case

with screws 5.

● For machines delivered without a table, the metal plate 1 included with the accessories
must be mounted so that it is flush with the lower edge of the table top and with the left
edge of the table top cutout (see Fig. 8.0.6).

● Insert the machine in the table top.

● After loosening screws 3, push switch 2 forwards until it touches the plate 1.

● In this position tighten screws 3.

● If the machine is tilted backwards,

switch 2 prevents the motor from
starting accidentally. "ERROR 92"
appears on display 4.

● After the machine has been placed in an
upright position, switch off the motor
with switch 5.

● When the motor is switched on again
with switch 5, the machine is ready for
operation.

Preparation

9 Preparation

All regulations and instructions in this Instruction Manual are to be observed!
Special attention is to be paid to the safety regulations!

All preparation work is only to be carried out by appropriately trained personnel.
Before all preparation work, the machine is to be separated from the electricity
supply by removing the plug from the mains or switching off the On/Off
switch!

9.01 Inserting the needle

Switch off the machine!
Danger of injury due to
unintentional starting of the
machine!

Only use needle system
DBx1 or 134R, depending on
machine equipment!
Observe sticker on machine!

● Raise needle bar.

● Loosen screw 1 and insert needle 3 until

you feel it stop.

● The long needle groove must be aligned
in the direction of the machine head.

● Tighten screw 1.

The selection of the correct needle depends on the model of the machine and
the material and threads being sewn (see chapter 3 Specifications).

Fig. 9 - 01

Preparation

9 - 2

● Place an empty bobbin 1 onto bobbin shaft 2.

● Thread the bobbin in accordance with Fig. 9-02 and wind it anti-clockwise around bobbin

1 a few times.

● Switch on the bobbin winder while at the same time pressing bobbin winder spindle 2
and lever 3.

The bobbin fills up during sewing.

If the machine is only run for bobbin winding (without sewing), a hook
base must be fitted in the hook.
Otherwise a jammed thread may damage the hook!

● The tension of the thread on bobbin 1 can be adjusted with knurled screw 4.

● The bobbin winder stops automatically when bobbin 1 is full.

If the thread is wound unevenly:

● Loosen nut 5.

● Turn thread guide 6 accordingly.

● Tighten nut 5.

Danger of injury due to
unintentional starting of the
machine!

Removing the bobbin case:

● Tilt back the machine.

● Raise latch 1 and remove bobbin case 2.

Inserting the bobbin case:

● Press bobbin case 2 until you feel it snap
into the bobbin case base.

Return the machine to its
upright position using both
hands!
Danger of injury by crushing
between the machine and the
table top!

Fig. 9 - 03

9.04 Inserting the bobbin case / Adjusting the bobbin thread tension

● Insert the bobbin into the bobbin case.

● Pass the thread through the slot under

the spring according to Fig. 9-04.

● Pass the thread through the notch.

● Adjust the thread tension by turning

screw 1.

When the thread is pulled, the
bobbin must rotate in the
direction of the arrow.

These maintenance intervals are calculated for the average running time of a
single shift operation. If the machine is operated more than this, shorter
intervals are recommended.

10.01 Cleaning the machine

Switch off the machine!
Danger of injury due to
unintentional starting of the
machine!

● Tilt back the machine.

● Clean the hook and hook compartment

daily, more often if in continuous
operation.

10.02 Topping up the oil tank (only on PFAFF 1181 and PFAFF 1183)

The PFAFF 1051 and 1053 are totally maintenance-free and run without any oil.

The oil reservoir must always
have oil in it.

● Whenever it is necessary to refill the
reservoir, 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
arrow).

Return the machine to its
upright position using both
hands!
Danger of injury by crushing
between the machine and the
table top!

Only use oil with a mean viscosity of 10.0 mm2/s at 40°C and a density of

0.847 g/cm3 at 15°C.

We recommend PFAFF sewing machine oil, part no. 280-1-120 105.

On the PFAFF 1051, 1053, 1181 and 1183 do not use a screw clamp on the
needle bar! The special coating of the needle bar could be damaged.

The illustrations in this chapter show the PFAFF 1053. Special attention is
drawn to differences which apply to other machine types.

11.01 Notes on adjusting

All adjustments in these adjustment instructions are based on a completely installed
machine and must only be carried out by appropriately trained specialists. Covers on the
machine which sometimes have to be removed and replaced for checks and adjustment
work are not mentioned here. The screws and nuts in brackets () are attachments of
machine parts which are to be loosened before making the adjustment and tightened again
after the adjustment has been carried out.
