RL160 bags sucked up

glenhyrst All Messages By This Member #134007 17 years I've had this RL160 and it's only recently started to suck up the bags again.? Thinking one or both may have been holed, I changed the bags for new ones but it has happened again. I recall that it did this shortly after I purchased it but this was resolved until now when I dialled up the little rotary switch that I presume adjusts the vacuum pressure to hold the bags down. Should I do this again? There is no obvious point of leakage - both plastic see-through windows are sealed. Not sure what might have changed to cause this. Any thoughts? Thanks. Phil
Rainger Pinney All Messages By This Member #134010 Hi Phil,? At the back of the machine there's a pipe that seats onto a gasket in between the two bags when you lift the bag bin into place.? This diverts suction to the bottom of the bin to hold the bags down.? If you don't have a good seal here, or if a bag is covering this orifice, the bags can get sucked up.? Hope that helps!? toggle quoted message Show quoted text On Fri, Jan 5, 2024, 7:16?AM glenhyrst <phil_moger@...> wrote: 17 years I've had this RL160 and it's only recently started to suck up the bags again.?

Steve Rowe All Messages By This Member #134032 Phil, Rainger is correct.? Make sure the port is not blocked by the plastic bag.? To help prevent this, I made some long bungee cords to hold the bag away from the port. I then put a dust extractor over the port and suck the bags into the bin prior to putting the bin into place.? I then open several blast gates and turn on the dust collector to make sure the bags remain in place.? Then I am good to go. As a last resort, you could put some scraps of wood in the bottom of the bag to help hold it down but with the sequence described above, I have found that unneccessary. Steve
Brandon Nickel All Messages By This Member #134033 Check the integrity of the foam gasket that seals the port to the bins. Mine got pushed out of position. If that seal isn't tight then you won't get suction below the bags. Also, I have to be careful when lifting the bins. There's enough slop in the mechanism that it's easy to be off-center and again break that seal.? The dial you refer to isn't a pressure/suction adjustment for the bins, it's the differential pressure trip circuit that shuts down the machine if the filters get too clogged. The adjustment is for varying levels of differential pressure.

I still haven't found the apparent leak in the system that allows the backs to suck up to the filters, or any blockage, but after several episodes, it has settled down to normal. I suspect a likely area of wear on the seal and perhaps a less than careful bin replacement, although I'm not aware of any change in how I do this. Phil
Brandon Nickel All Messages By This Member #134069 Phil, after my original white foam ring seal was damaged, I cut a hole in a piece of ~2" square x 1/2" thick closed-cell foam that use for drawer liners. Then I glued that down to the bin. I still have to make sure the bins are roughly aligned when lifting, but the larger seal has improved my odds of success. Once there's some material in the bags it ceases to be a problem.
