CAUTION:
Do not attempt to
remove the Pivot
Bolt during tilt
adjustments!
Removal could
lead to serious
personal injury or
death. Adjustments
are made with the
Pivot Bolt
hardware loosened
but in place.
CAUTION:
This is a two
person activity. As
the Pivot Bolt is
loosened and the
Support Bar
hardware is
removed, the rack
is heavy and
unstable. It must
be held in place
by one person
while the second
person loosens
and removes the
hardware and then
re-installs/tightens
the hardware back
in place. Failure to
do so could lead
to serious
personal injury
and damaged
components.
