Always put a block of wood under the knee. and lock the knee.
The possiblity exists that the bouncing will blow out the acme nut
holding up the knee, particularly if its an older machine with a well
worn knee acme screw and nut.
I saw this happen one time. Drove the knee screw through the top of
the trailer deck. Very rare, but a chunk of wood is cheap.

Political Correctness is a doctrine fostered by a delusional,
illogical liberal minority, and rabidly promoted by an
unscrupulous mainstream media, which holds forth the
proposition that it is entirely possible to pick up a turd by the clean end.
