Properly Releasing Spring Tension
This repair instruction describes how to properly release the spring tension from the F2B system when the tarp is fully covered and the cross arm is resting on the tailgate. See section below if F2B system will not return to fully covered position.

Spring and arms are under extreme tension. Broken or damaged components could cause death or serious injury. Follow all instructions on releasing spring tension before making any repairs.
Check for overhead power lines.
Always check for overhead obstructions before covering and uncovering.
DO NOT operate under low hung power lines.
Be sure that your working platform is secure. Use OSHA approved ladders or scaffolding to work above ground level.
Always wear safety glasses.
