I experienced a problem with my CG-15 vacuum sealer recently. It would not pull a vacuum past "2". Should go to "9". After a little research online, I sent an email to the Weston Company to see if they could help me. I received both an email response and a phone response within hours. I talked to a young lady who walked me through taking the cover off the unit and explaining in some detail why this happened. I just ordered two parts and some of their bags. She indicated that part of my problem may have been caused by the Foodsaver bags I have been using. The vacuum pump must work harder due to the construction of the bags.
If you ever have any issues with your CG-15, please call them at 1-800-814-4895. This unit is very easy to do your own maintenance on.

BTW. Weston no longer supplies the CG-15 to Cabelas. They went with a different (i.e., cheaper) vendor for the replacement product. Cabelas would like you to contact them for any help you need. If they don't carry the product any longer, I would be suspect of any information they might give you. I'll go to the source.
