Tri-pin System Adjustment:
Your UPPERTONE's front station should have a single user or multi-user trip-pin system used for the rowing
and chest press exercises.
Use the tri pin system by placing your hand so that your wrist is between the two rear pegs with your fingers
around the front peg, if possible.
For both systems the two rear pegs should be adjusted so that they grip the wrist firmly, but not too tightly.
For the multi-user model, the distance between the pegs can be adjusted by turning the knob. For the single
user-model you should have someone adjust the pegs to fit your wrist. Once adjusted, you should not have to
adjust them again.
When the tri-pin system is correctly adjusted, you should able to do the chest press and rowing exercises
without your hand slipping out from between the pegs.
This adjustment applies to:
(a) Narrow grip chest press
(b) Wide grip chest press
(c) Narrow grip rowing exercise
(d) Wide grip rowing exercise
