Connecting the DHS790 exhaust port to Rigid vacuum
Purchased a RIGID 6.5 gallon wet dry vacuum to connect to the 1 1/2 inch exhaust port on my DeWalt DHS790. However, the three piece DeWalt vacuum accesory adapter kit had NOTHING to connect my RIGID 1 1/2 inch hose end to the DHS790. FIX was at Home Depot, a "Fernco" 1 1/4 inch x 1 1/4 inch Flexible PVC Coupling with metal screw couplers at each end of the rubber coupler. Remove one metal coupler and discard, lossen the other metal coupler and slide that end fully onto the exhaust port then tighten the metal coupler. Half of the rubber coupling accepts the 1 1/2 inch end of the hose from the RIGID Vacuum. In addition, the rubber coupling also accepts the accesory kit adapter from 1 1/2 inch to 2 inch vacuum horses.
