.01 Servicing and maintenance intervals
Cleaning the machine ...................................................... Daily, before starting the machine
Clean the hook compartment ...............................Daily, several times if in continuous use
Check the oil level ........................................................... Daily, before starting the machine
Greasing the bevel gears ....................................................................................once a year
Clean the blower air fi lter ................................................................................... as required
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.
11 .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 individual case.
Fig. 11 - 01
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 .
● Bring the needle bar to its highest position.
5 mm
2
● Open the post cap and remove the bob-
bin case cap and the bobbin.
● Unscrew hook gib 1.
● Turn the handwheel until the point of
bobbin case 2 penetrates into the groove
of the hook race approx. 5 mm.
1
● Remove bobbin case 2.
● Clean the hook race with paraffi n.
● When inserting the bobbin case 2, ensu-
re that the horn of the bobbin
● case 2 engages in the groove of the
needle plate.
3
● Screw hook gib 1 back on and close the
post cap.
Do not operate machine while
post cap is open!
Risk of injury from rotating
clamp!

Care and maintenance
11 .03 Oiling the hook
Switch the machine off!
Danger of injury if the machine
is started accidentally!
● Before commissioning the machine, and
after long periods out of operation, pour
a few drops of oil into the hook race (see
arrow).
Only use oil with a mean viscosity of 22.0 mm²/s at 40ºC
and a density of 0.865 g/cm³ at
15ºC.
We recommend
PFAFF sewing machine oil,
Fig. 11 - 03
part number 280-1-120 144.
11 .04 Monitoring the oil level for clamp and head pieces
● Before commissioning the machine,
fi ll in oil through hole 1 until the oil level
indicator 2 is at the "MAX" marking.
● Check the oil level daily before starting
the machine!
The level of the oil in indicator 2
must not sink below the "MIN"
marking and not exceed the
Max
Min
2
● If required, fi ll oil into the tank through
hole 1.
