8-3. Lubrication

Like most other equipment, the case sealer must be
lubricated periodically to ensure long, trouble-free
service. Most of the machine bearings are perma-
nently lubricated and sealed and do not need further
lubrication. The drive motors and cylinders are also
permanently lubricated and do not require additional
lubrication.
Caution
During lubrication, wipe off all excess
lubricant and grease. Excess lubricant
attracts dust and dirt that can cause
equipment wear and jamming. Take care
that no lubricant or grease remains on the
surface of rollers around which tape is
wrapped.

8-3-1. Taping Heads

Figures 8-1 and 8-2 illustrate the taping head points
that should be lubricated after every 250 hours of
operation.
For each taping head:
1. Apply a small amount of multipurpose grease
to the guides and to the ends of each spring
where the spring loops are secured. Refer to
Figure 8-1.
Figure 8-1. Lubricating Guides and
Spring Loops
2. Apply 3M 5-Way Penetrant (62-4696-2730-1)
to all pivot points of the taping head. Refer to
Figure 8-2.
3. Apply 3M 5-Way Penetrant to the tape cut-off
knife oiler pad. Saturate the pad.

8-3-2. Main Assembly and Infeed Assembly

With reference to Figure 8-3 and the associated
figures in Section 7, Illustrated Parts Breakdown,
lubricate the machine wear points as indicated.
1. Side Belt Drive Closure Assembly
At 250 hours, use multipurpose grease.
•Lightly coat chain pitches
(Figure 7-5, # 17 and #18).
•Lightly coat outside diameter of the shafts of the
arm assembly (Figure 7-5, #1, #2, #3, and #4).
•Lightly coat inside diameter of bushing
(Figure 7-13, #89) use grease fitting,
(Figure 7-5, #38) use needle point gun on
this fitting.
