NOTE: The pneumatic piston is pre-set at
the factory for level installation (monitor and
keyboard portion of worksurface in same
horizontal plane). From this position, the
piston must extend and compress, to allow
the full range of motion of the mechanism.
CAUTION: Do not depress button on the end of the
pneumatic piston. If piston becomes fully extended,
compress it prior to assembly by pushing down
against hard floor, and very quickly rotating up, so
that button pops back out before the piston has a
chance to extend.
