When the overlock machine does not sew well, summon the technician..not that I have not tried servicing it as best as I know how :(
Took out all the threads..wiped all the dust..adjusted the knobs..poured a little bit more oil but still it did not sew well.
Oh well...no choice but to summon the technician, he will be coming this afternoon and hopefully I'll be able to sew smoothly after this.
Can't let the customers wait too long for their 'anak tudung'.
