Learning Event 2:
IDENTIFY LUBRICATION POINTS AND PROCEDURES
1.
Lubrication must be performed at a regular interval to keep the moving parts from wearing
excessively.
a. The symbol M stands for a period of one month. A month, as defined for lubrication purposes,
consists of 30 days of 8-hour per day operation. When equipment is operated more than 8 hours a day, the
lubrication intervals must be adjusted to prevent excessive wear. For example, if the equipment is operated
16 hours a day instead of 8, the drum bearings must be lubricated every 15 days instead of every month. In
very hot weather or under dusty atmospheric conditions, the equipment will require more frequent
lubrication. Lubricate the equipment according to its needs.
b. For the EL-5(1), remove the control box cover assembly by removing the screws and
lockwashers. Lubricate the drum bearings, the drive roller bearing, and the squeegee roller bearings (figs.
3-3 and 3-4) as indicated in Figure 3-5. Semiannually refer the lubrication of the EL-5(1) motor reduction
gear case assembly to a higher category maintenance.
