11.To attach the cartridge lock, hook the square part of the grounding spring to the metal chassis, then pull down and attach the lock on the metal shaft.
NOTE: Replace all four cartridge locks, even though the others may not be broken. If one lock experienced failure, the others are more prone for failure later.
12.Attach one end the four springs to the white slide lever and install the lever back into the machine. (** Attach the other end of the spring in step 15.) Place the white slide lever so the two metal tabs are in place (circled below), then adjust all the black cartridge locks to be ?under? the tabs on the white slide lever. Bend the top of the white slide lever out to put the top black cartridge lock in place. Slide the white slide lever up when all the black cartridge locks are in place.
