Operation (Continued)
Pressure Regulator (Figure 3-3)
Regulates main air pressure to the machine to
adjust pressure, pull knob up and turn; push
down to lock setting.
Filter (Figure 3-3)
Removes dirt and moisture from plant air before
it enters the case sealer pneumatic circuits. If
water collects in bottom of bowl, unscrew the
valve on the bottom of bowl to drain. When
empty, retighten valve.
Emergency Stop Switch (Figure 3-2)
The machine electrical supply can be turned off
by pressing the latching emergency stop
switch. To restart machine, rotate emergency
stop switch a quarter turn clockwise to re-
leases switch latch. Restart machine by
turning the switch to the "O" (Off) position then
to "I" (On).
Upper Drive Assembly Actuator Switch
(Figure 3-2)
This switch, when touched by the leading edge
of a box , pneumatically raises the upper drive
assembly to allow insertion of the box under
the drive belts. As the box moves under the
switch, releasing it, the upper drive assembly
descends on the box and the drive belts
convey the box through the machine. When
switch is turned, the upper drive assembly
rises. When the switch is released, the upper
drive assembly descends to its rest position.
Centering Guide Switch (Figure 3-7)
This pneumatic switch controls the box
centering guides. When switch is activated by
a box entering the case sealer, the centering
guides close (centering the box), and released
(after box passes over switch), the guides
open.
Air Pressure Regulator, Centering Guide
Force Adjustment (Figure 3-4)
This regulator is used to adjust centering
guides according to weight of boxes. Pressure
should be adequate to center boxes, but low
enough to allow easy pushing of boxes under
taping head.
To adjust the regulator setting, pull the knob
outward, rotate the knob to the desired setting.
Push the knob inward to lock it and prevent
unintentional adjustment.

Air Pressure Regulator, Top Drive Assembly
Force Adjustment (Figure 3-5)
Set nominally to control the "down" movement of
top drive assembly and the pressure exerted
against the box as shown in Figure 3-5. The
regulator setting is changed as necessary for the
boxes being sealed to provide adequate drive belt
pressure against the box to positively convey the
boxes through the machine. If the boxes stop or
hesitate while being conveyed, decrease the
regulator pressure. This increases the drive belt
force on the box for more friction between the box
and drive belts. Adjust the pressure setting as
necessary to get continuous movement of boxes
through the machine.
