Understanding the machine
This was one of the first of the "Hands Free" line of machines. The idea here is to create a vacuum in a channel. A black gasket surrounds a channel, and a chamber comes down on top of the gasket to seal around the channel. With the open bag in the channel the air is drawn out of the bag. Pressure is required on the lid until a vacuum is achieved. Once the bag has collapsed, and there is a positive vacuum in the bag, the lid will stay down all by itself "hands free". On this model the pump will stay active until the desired vacuum is achieved. The heat bar will activate all by itself. The adjustment for the vacuum is controlled by a dial on the left side of your machine. From minimum to maximum the choice is yours, and there are push button overrides for both the seal and the vacuum..
This machine gets the pressure necessary to create the heat seal from the vacuum in the channel.
This thing is not vacuuming the way it use to: This is sometimes caused by the "channel gasket" crushing down over the years. Try removing the gasket and soaking it in a silicone lubricant, the stuff you use on the dash board of your car, or the silicone that skin divers spray on the inside of their wet suites to keep them supple. DO NOT use the spray cans for metal parts they have stuff in them that is not kind to rubber gaskets. Keep the gasket out for a day or two to fluff it up then reinstall it. Or buy a new one (not a machine just the gasket).
The Gage that tells me when it is ready to seal does not go to green: Here is a sticky situation. The gage is essentially a sliding valve it gets a build up of the vapor, then gets pulled through the machine, and causes the slide, not to move. Short of taking the machine apart there is no way to fix this issue. So send the machine to us. Do not try to flush these machines! This is not a home repair, sorry.
