Is there anything that would create and overly tight condition where the
feed arm is really, really tight and hard to depress to get the tooling to
move. I tried another machine the other day and it was like butter. Mine
requires quite a bit of effort to lower and raise the handle. I keep the
oil caps filled and run it up-and down regularly when not in use. I see no
pitting or rust anywhere. Is there something simple I'm missing?
Any help is appreciated.
