Preventative Maintenance & Proper Use Tips*
|

Heater Bar Cleaning
(Applies to HS-B and HS-BII) |
Over time,
residue from your bags may build-up and burn on to your sealer's heater
bars. This is especially true if the interior poly surface of the
package is exposed to the heater bars! To minimize build-up on your
heater bars, an easy and convenient methods of cleaning is as follows:
1) Heat-up
machine to a temperature setting that is in the high-end of the adjustment
range
2) Take a piece
of cardboard (the back of an average writing tablet works perfectly) and
feed it through the sealer, just like you would a bag or pouch. As
the cardboard passes through the heater bars, it essentially "squeegees"
material off of the heater bar surfaces.
3) Repeat the
process, either trimming the cardboard, or using different sides, until
the cardboard passes through the machine clean, without picking up and bag
residue.
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! |

Compression Roller Cleaning
(Applies to HS-B and HS-BII) |
Regularly - with
nothing sharper than a fingernail, remove any packaging material from both
compression rollers on a regular basis. Too much build-up on the rollers
can cause the rollers to put uneven pressure on the bag, resulting in
voids in the seal area.
On the HS-BII
sealers, too much build-up can also cause the machine's frame to crack! |
|
Heater Bar Gap Adjustment:
(Applies to HS-B) |
For most
applications, the gap between the heater bars should be 0.025" (measured
with a feeler gauge.) |
|
Heater Bar Gap Adjustment:
(Applies to HS-BII) |
For most
applications, the gap between the heater bars should be 0.025" (measured
with a feeler gauge.) |
|
Feeding Bags:
(Applies to HS-B and HS-BII) |
If your pouches
have a lip (i.e. one side is longer than the other - to make the pouch
easier to open) when possible, try to insert your pouches into the sealer
so that the exposed lip of the pouch is positioned above the top of the
seal bars and compression roller. If the lip, and inside of the pouch, is
exposed to the heat and compression sections, the poly interior material
will build-up faster on the heater bars and compression rollers. If the
exterior paper, foil, or barrier material is the only thing that is
exposed directly to the sealer's working parts, the machine will stay
cleaner longer. |
|
General Sealer Set-up:
(Applies to HS-B and HS-BII) |
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. |
