15.2.2 Checking the hook lubrication
Fig. 85: Checking the hook lubrication
The approved oil quantity for hook lubrication is a factory specification.
Hold a piece of blotting paper next to the hook (1) while sewing.
Proper setting
After sewing a stretch of approx. 1 m, the blotting paper will have been
sprayed with a thin and even film of oil.
To set the hook lubrication:
1. Turn the screw (3):
• Release more oil: turn counterclockwise
• Release less oil: turn clockwise
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.
