OPERATIONAL INSTRUCTIONS
Incline Angle Adjustment
There are three adjustment holes in the bracket on the MAIN FRAME(1) which allow the REAR
SUPPORT(12) to be attached in three different incline positions. Pull the SPRING KNOB(16), then swing
the REAR SUPPORT(12) to desired position and lock in one of the incline positions with the SPRING
KNOB(16). More incline angle will offer more stretch force.
