ADJUSTING THE SAFETY SPOTTERS
Before using your barbell (not included), set the Safety Spotters (6) at the lowest point to which you want your barbell to move.
To do this, hold a Safety Spotter (6) and pull out the Long Pin (32). Move the Safety Spotter to the desired height, and reengage the Long Pin into the Safety Spotter and the Upright (5).
Adjust the other Safety Spotter (not shown) and the two Weight Rests (7) in the same way.
WARNING: Always adjust both 
Safety Spotters (6) and both Weight Rests (7) 
to the same height.
