Troubleshooting Tips and Part # Information

When the Teflon wears off of your HS-C's sealing bands or if the bands get scratched, kinked, or broken, they will need to be replaced.

To change the bands on an HS-C, unplug the machine and remove the bottom guards.  Press the discharge-end (idler) band wheels (pulleys) in against their spring-loaded cams to take tension off one of the the sealing bands.  Slip the worn sealing band off of the Idler pulley, pull it out of the heater bar/cooling bar slot, then remove it from the drive pulley.  Repeat the process for the other sealing band.

Reverse the process to install new sealing bands - install one band at a time - place the new band over the drive-end pulley (the pulley at the motor end of the machine), then slip the band carefully down between the cooling and heater bars.  Finally, press on the Idler Pulley (against the tension spring/cam) and slip the new band onto the Idler Pulley.  Release the pulley to put tension on the band.  Make sure the outside edge of the sealing band is fitted into its respective Band Wick.

Repeat the process for the second band.

The Band Wicks are intended to "wipe" the Teflon surface of the sealing bands.  The Sealing Band should run through one of the two slots in the band wicks and the band wicks should be inserted into the sealer frame with the slot openings facing the bottom of the machine.  The Band Wicks help to keep the Teflon clean.  Band Wicks can be rotated so that when one slot gets dirty, the second slot can be used to clean the band - allowing you to double the life of a band wick.

If the gap between the heater bars becomes occluded (clogged) with burned-on residue, the bars will likely need to be removed, cleaned, and polished.  It is NOT recommended that the user attempt to remove the heater bars because replacing them properly is difficult and critical to proper sealer operation.  If this occurs, please contact BaggingGuys about our Ship-In Service for Doboy Portable Sealers!

When the Teflon wears off of your HS-CII's sealing bands or if the bands get scratched, kinked, or broken, they will need to be replaced.

To change the bands on an HS-CII, unplug the machine and remove the plastic guards.  On one side of the machine, press the infeed end (idler) Band Wheel (pulley) Assembly in against their spring-loaded pins.  Push the loose metal clip up behind the head of the shoulder screw (the one that retains the tension assembly and the band tension springs) to lock the tension assembly in (and keep tension off the pulley and bands.)  Slip the worn sealing band off of the Idler pulley, pull it out of the heater bar/cooling bar slot, then remove it from the drive pulley.  Repeat the process for the other sealing band.

Reverse the process to install new sealing bands - install one band at a time - place the new band over the drive-end pulley (the pulley at the motor end of the machine), then slip the band carefully down between the cooling and heater bars.  Make sure the outside edge of the sealing band is fitted into its respective Band Wick.  Finally, put it on the Idler Pulley and snap the clip out from behind the should screw to restore tension to the sealing band.  Repeat the process for the second band.

Use compressed air to regularly blow accumulated dust off of the exterior and out of the interior of the machine.

Periodically, inspect the HS-C and HS-CII sealer's black, Teflon-coated metal sealing band for wear and scratch of the Teflon coating.  For most applications, the the Teflon is important - i.e. it prevents the bag from sticking to the sealing bands.

If you need to order replacement sealing bands or band wicks, let us know and we will provide you with a quote.  HS-C and HS-CII Sealing Bands are sold in 10-pack cartons.

For most applications, the gap between the sealing bands should be 75% of the total thickness of the material you are sealing (measured with a feeler gauge inserted at the heating and cooling bars, behind one of the sealing bands - DO NOT insert the feeler gauge between the sealing bands as it will likely scratch off the Teflon coating.)

Many Doboy machines we receive for service have been user-adjusted in a way that defeats the machine's ability to operate properly.  The sealer is designed to have a fixed side and a spring-loaded side - this applies to the heater bars and the belt/chain guides.  We will gladly try to talk you through proper set-up of your machine - Call us!
