1Electrical "On/Off" Switch

The box drive belts are turned on and off ("Off button is red) with the electrical switch on the left side guard on the infeed end of the machine.

Note The case sealer has a circuit breaker located in the electrical control box on the lower right side of the machine frame. If circuit becomes overloaded and circuit breaker trips, see "Maintenance – Circuit Breaker", page 22.

2Main Air "On/Off" Valve/Pressure Regulator/ Filter – Figure 3-3

This set of pneumatic components controls, regulates and filters plant air supply to the two separate control circuits of the case sealer.

"On/Off" Valve – "On" turn to "SUP" – "Off" turn to "EXH". Note Turning air supply "Off" automatically bleeds air pressure from the case sealer air circuits.

Always turn the air "Off" when machine is not in use, when servicing the machine, or when connecting or disconnecting air supply line.

Note The air valve has provisions for lockout/ tagout according to plant regulations.

Pressure Regulator regulates main air pressure to the machine. The factory set point if 95 PSIG. To re-adjust pressure, pull knob up and turn to desired pressure. Push down to lock setting.

Filter removes dirt and moisture from plant air before it enters the case sealer pneumatic circuits. If water collects in bottom of bowl, lift up on the valve on the bottom of bowl to drain.
