Pull out strap and make sure it emerges without jerking.
Check belt strap for
- folding
- unravelling

Retract belt strap; here the inertia reel mechanism must retract the strap automatically and without squeaking noises, the last section of the strap may have to be fed in.
Pull out belt strap in short tugs - locking reel must lock.
