Regardless of how enthusiastic you may be about getting on your
equipment and exercising, take the time to ensure that your safety is not
jeopardized. A moment’s lack of attention can result in an accident, as
can failure to observe certain simple safety precautions.
1. Read, study and understand the Assembly Instructions and all the
warning labels on this product. Furthermore, it is recommended to
familiarize yourself and others with the proper operation and workout
recommendations for this TuffStuff product prior to use. Some of
this information can be obtained in this Assembly Instructions, as-
well-as from your local TuffStuff Retailer.

sure all warning labels are legible and intact. Replacement of the
Assembly Instructions and labels are available from your local
TuffStuff Retailer.
3. Consult with your physician before beginning any exercise
program.
4. Use proper discretion when children are present.
5. Keep hands, limbs, loose clothing and long hair well out of the way
of moving parts.
6. Do not attempt to lift more weight than you can control safely.
7. Inspect the Smith-Half Cage for any sign of wear on parts, hardware
becoming loose or cracks on welds. If a Problem is found do not
use or allow the machine to be used until defective part is repaired
or replaced.
8. The Press Bar (#12) has a swivel locking mechanism that allows
you to safely lock out the Press Bar (#12) at virtually any setting.
See Fig. A.
9. If you are adding or storing weight plates on the Olympic Adapters
(#10), do not over-load them. Allow enough space for weight collars.
See Fig. B
10. Pay special attention to the Turn/ Pull Pins w/Knob (#134) located
on the Bar Holders (#9) and the Bar Safety Spotters (#7, #8). Be
sure they are fully engaged into the selectorized holes of the Front
Uprights (#3). Refer to Fig. C for further illustration.

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
Retailer.

12. The illustrations above depict the Press Bar disengaged setting which is used
during exercise.
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 first 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.
