11. DANGER: Once the unit is completely assembled take the time to ensure
that the unit is assembled correctly square and perpendicular. Pay special
attention to the Press Bar (#12) making sure both hooks engage uniformly and
completely into each locking position. If both of the Press Bar Hooks are not
engaging uniformly into the receptacle holes, it will be necessary to loosen
some frame hardware then re-align the frame and re-tighten the hardware.
If Problem persists, Do Not Use the Machine and contact your TuffStuff

13. DANGER: The Safety Spotter Hooks (#14, #15) prevent the Press Bar from
being lowered below required point and avoid getting crushed under the Press
Bar (#12) if the weight is too heavy to control. Use the Decal-numbers (#58)
on the Front Uprights (#3) to ensure that the Safety Spotter Hooks (#14,#15)
are set to an equal adjustment setting (same height).
Before you add weight plates to the Press Bar (#12), you must fi rst set-up the
Safety Spotter Hooks (#14,#15) for the required exercise. It is recommended
that you test the desired setting without weight plates on the Press Bar (#12)
to make sure the Safety Spotter Hooks (#14,#15) are set to the appropriate
exercise setting.
