Learning Event 2:
DESCRIBE THE STEPS NECESSARY TO PERFORM LUBRICATION SERVICES
1.
The contact printer has a felt clutch (fig. 2-3) that should be lubricated monthly with lubricating oil.
Figure 2-3. Felt clutch lubrication
CAUTION: When lubricating the contact printer, be sure to remove oil excess or spilled
lubricant from the equipment immediately. Excessive or sloppy lubrication can cause
damage to the contact printer and the sensitized materials processed by the equipment.
2.
A month consists of 30 days of 8-hour operation. When the contact printer is operated more than 8
hours a day, the lubrication intervals must be adjusted to prevent excessive wear. For example, if the contact
printer is operated 16 hours a day instead of 8 hours, the felt clutch must be lubricated every 15 days instead
of every month. In very hot weather or under dusty atmospheric conditions, the felt clutch will require more
frequent lubrication.
