3M-Matic 800rf Case Sealer Adjustments

3-15. Cylinder Cushion Setting
ü Note
This is a generic approach to adjusting the cylinder
cushion settings for all cylinders used in the 800rf
Case Sealer.
This is not a routine adjustment. Normally, it is not
necessary to adjust the cylinder cushion settings
unless a new cylinder is installed to replace an
original component.
Specification
Adjust cushion settings so that the cylinder does not
bottom out hard at the end travel of its stroke.
Adjustment
Set the cylinder cushions for the setting that allows
proper operation as described in the above specifica-
tion. Typically, these are factory set and do not need
to be adjusted.
1. Refer to Figure 3-16 for adjusting screw loca-
tions. This is a generic view for all cylinders used
in the 800rf Case Sealer.
2. Turn the adjusting screws fully CW (closed).
3. Adjust by turning the screws 1/8 to 1/4 turn
CCW.

3-16. Paddle Pressure Regulator
Specification
The Paddle Pressure Regulator should be set so that
as the paddle makes contact with the top of the carton
when the upper head assembly descends, it does not
overtravel and deform the carton.
Adjustment
1. Refer to Figure 3-17. Adjust the Paddle Pressure
Regulator on the underside of the Pneumatic
Control Panel so the gauge reads 7 PSIG with
the Main Air Pressure Regulator set correctly
(CW increases pressure, CCW decreases
pressure). Observe the Paddle Pressure Gauge on
the top of the panel.
ü Note
Too much pressure results in excessive drag on the
top of the carton or deforming of the carton.
