Guldmann Active Trainer Manual página 21

When using the hanger (bar) with Active
Trainer, position the hanger (bar) to the
rear of the user's head while attaching
the straps and prior to the user coming to
standing.
Check that the support straps are correctly
tensioned. There should be no more than
max 15 cm / 6 inch space at the back
where the rear straps cross in between
the two halves of the trainer sling.
Make sure that the size of the lifting
hanger fits the user.
Have the user lean slightly forward and lift
a bit until the strap stretches.
Check the tension of the support straps'
again.
Then start the actual lift.
You must not lift to such a height that
the user is lifted off the floor.
