For a right handed person the safest way is to swing a prop is from the front for an engine which rotates clockwise (Looking from the front) i.e. the Gypsy Major and from the rear for an engine which rotates anti-clockwise. i.e. Lycoming.
For a Tiger or Chippy:
Prop blade in the 2 o-clock position, both hands on the training edge of the prop, pull down against compression and follow through by moving your body in the same direction. As the prop reaches the 6 o-clock and fires, or kicks back your hands and body should be clear of the path of rotation.
Did about 300 hours combined on those two aircraft and it worked for me, but was a lot younger then
