open bobbin door and remove bobbin case.turn handwheel slowly and observe needle position in relation with hook.if timing is correct the hook point should be close to needle eye when needle is approx 4mm from bottom turning point of needle on upwards movement.that means when the needle is moving upwards and approx 4 mm from bottom turning point the hook and needle eye should be no more than 1mm away from each other.if that is close just make sure needle is inserted correctly,that is flat side to back of machine and cotton threaded from front.if cotton does get picked up when handwheel is turned slowly but not when machine is at speed it could mean that tension is set wrong or take up spring not working
