Recently I sent an email asking about the DYNA-King cement reservoir I was having trouble with mine and was starting to hate it.
I don't think it is right that I was able to fix mine And I don't pass on the info I found out. So here is the scoop. If you have a DYNA-King cement reservoir and are having a bit of trouble with it Just jake a small amount of Vasoline to the O-Ring on the bobkin, It must be there all the time to protect the o-ring and it makes it go in and out like you think it should. If you did what I did and cleaned your whith Laqure thiner, They will send you A new O-ring, but if it is not to late just give it a shot and you'll start loving it again. Steve Clark
