4. Maintenance
4.1 Cleaning
Turn off main switch.
-Danger of injury! -
A machine kept clean is a safeguard
against malfunctions!
Therefore, specifically clean the area
under the throat plate, removing the
sewing dust once daily.
It is advisable to do this with an air pistol.
(If exists, remove the knee lever.)
After a certain period of time, the accumu-
lated sewing dust must be removed from
the feed dog rows. To do this, remove the
throat plate.
When the machine is equipped with a
compressed air maintenance unit, the oil
level is to be checked daily.
Before the water level reaches the filter
insert 3, the water must be blown off the
water separator 2. To do this, the
maintenance unit must be under
pressure and the screw 1 must be turned
in (left hand thread).
For checking the oil level see 4.2.

4.2 Lubricating
Turn off main switch.
-Danger of injury! -
For the lubrication of this machine
only use ESSO SP-NK 10 oil or an oil
of the same quality.
The following lubricating points need to
be supplied with oil:
–

housing 7 and, if necessary refill with
oil.
To do this, turn out the screw 8. With
the machine tilted backwards, the oil
level must not drop below the lower
long mark of the sight glass. Oil must
only be refilled up to the upper mark.
–
With upright machine, refill oil into the
oil reservoir 9 up to the mark "Max.".
The oil level must not drop below the
mark "Min.".
Except for the looper drive, all bearing
points of the machine are supplied by
a central oil wick lubrication out of
reservoir 9.
–
The oil check tube 10 for monitoring
the oil flow to the arm shaft front
bearing is located on the machine
arm. The oil flow must not be inter-
rupted while the machine is running.
Should the oil flow be interrupted in

spite of a filled reservoir, immediately
call a service technician.

If necessary, refill oil into the oil
reservoir 6 of the maintenance unit up
to the groove. To do this, completely
turn off the compressed air by turning
the knob 4 to the left, and then turn
