    [Reference] [Reference] The DSR-2000A/2000AP uses many small screws that easily fall inside the machine when removing and re- assembling parts. To avoid this risk, magnetize the screwdriver bit slightly enough to prevent small screws from falling into the machine. However, when installing the drum assembly, never use a magnetized screwdriver.
