DANGER: The CBR 50 is very heavy; it weighs more than 60 kg (132 lbs.). Do
not attempt to unpack, carry or move without proper equipment and sufficient
people to do so safely. Remember, always lift with your legs, not with your
back. If you have a history of back or cardiovascular problems, do not attempt
to unpack or lift the CBR 50.
The machine should be installed on a level bench capable of supporting CBR 50’s
gross weight, and with sufficient space for safe operation of the equipment. The
machine is provided with adjustable feet to compensate for any out of level, or
unevenness, of the bench surface.
