How To Use

Next, identify the existing lock components and compare their position and configuration with the replacement KB15B/KB17/SK279 set.

Finally, close and open the machine cover several times by hand to confirm that the lock engages correctly and the cover remains securely retained before returning the machine to production.
FAQs
What do KB15B, KB17 and SK279 refer to?
These are the component references used to identify the lock-set components within the Siruba 700F parts system. The official parts-list document shows KB15B, SK279 and KB17 together in the KB group.
What should I check before buying this lock set?
Check your existing part for the KB15B, KB17 or SK279 reference and compare the lock’s shape, mounting location and dimensions. This is especially important when the machine is a later 700F/700K variant rather than the standard 747 configuration.
Can a sewing-machine technician replace this lock set?
Yes. It is a mechanical replacement component and can normally be replaced during routine machine maintenance. The machine should be switched off and disconnected from power before removing covers or working around the locking mechanism.
What if the machine cover still does not lock after replacement?
First check that the lock components are correctly positioned and fully secured. Also inspect the mating cover or latch area for bending, damage or excessive wear. A damaged mating component can prevent a correctly installed lock set from engaging properly.
Is this part supplied as one piece?
The supplied product information identifies it as a lock set, rather than a single isolated screw or spring. The exact contents should be matched against the physical product supplied with your order.
