The rubber fingers are the very important parts of a plucking machine and are easily destroyed during the daily heavy using, so we need to know the way of replacing the rubber fingers as quickly as possible.

Step 1 is to remove the used rubber finger:
Holding the rubber finger by one hand, then inserting a screwdriver (straight type) into the edge of the rubber finger by the other hand and prying up to take out the broken rubber finger.

Step 2 is to put in a new rubber finger:
Holding the new rubber finger by one hand and taking a screwdriver (straight type) by the other hand. Insert the rubber finger to the hole by the screwdriver.
