Fig. 115: Setting the hook lubrication
The approved oil quantity for hook lubrication is a factory specification.
Hold a piece of blotting paper (2) next to the hook (1) while sewing.
Proper setting
After sewing a stretch of approx. 1 m, the blotting paper (2) will have been
sprayed with a thin and even film of oil.
To set the hook lubrication:
1. Open the throat plate slide ( p. 20)
2. Turn the screw (3):
• Release more oil: turn counterclockwise

Important
The released amount of oil does not change until the operating time has
run a few minutes. Sew for several minutes before you check the setting
again.
