Drum is one of the main parts of printing machine, which must be wiped at any time in each shift to keep the surface of drum clean, especially in impression cylinder.

Lack of oil, blocked oil circuit, damaged refueling device, loose screws, falling off, etc. , should be timely refueling and maintenance (especially don't forget to refuel at both ends of the spindle and impression cylinder gripper shaft).
It is forbidden to wipe the equipment with broken cotton yarn and rags to prevent accidents caused by falling into the machine.
