Need an owner's manual on line
Posted by LinJay on Jun 09, 2008
I have lost my owner's manual for my shop vac and need to figure out how to set it up so I can pump out my flooded basement using a garden hose.
Is there anywhere I can find an owner's manual on line??
The model stated on my vac is not what I clicked on your site....my vac states:
Model QPV 10.5
