Basic Maintenance on Class 2000 &
3000 Portable Bag Closing Machines

Union Special Corporation bag closing machines are known world wide for their sturdy design, reliability, and durability. The Union Special Class 2000 Portable Bag closing machine is a fast, efficient, lightweight machine for closing bags made of jute, cotton, linen, paper or plastic, with a single-thread

With its direct drive fan-cooled electric motor, fiberglass-reinforced break-resistant motor housing and handle, heavy-duty automatic shut-off, carbon brushed, dustproof, permanently lubricated ball bearings, 16 foot power cord and built-in chain cutter, the Union Special Class 2000 is an ideal
machine to have in any facility. The Class 2000 can be used as your main machine or as a spare when your other bag closing machines are in need of service.

As it is with all machines, maintenance is a key factor to keeping your facility running efficiently and smoothly. The Union Special Class 2000 should also be serviced and maintained regularly to keep it running smoothly and efficiently. The following are the recommended steps for properly maintaining the Class 2000 machines.

  1. Inspect the power cord and plug for signs of wear, Figure 1. A damaged outer cord could mean that the wires on the inside are also damaged and shocks could occur. Replace or
    repair as needed.
     
  2. Inspect the thread stand to see if it is bent or broken, Figure 2. It is important that the thread come directly
    off the center of the cone. Replace or repair as needed.
     
  3. Remove the outer cover opposite the thread stand by loosening the 10 Phillips head screws, Figure 3.
     
  4. Check the switch for wear and replace if needed, Figure 4.
     
  5. Clean the motor area and air slots, removing dirt and other contaminants with a small brush, rag or compressed air, Figure 5.

    Note: Care must be taken not to damage any of the electrical components.
