Manual crank spring tensioning system

Manual crank spring tensioning system:

Operating Procesure:

1.  Place string into the string gripper.
2.  With the left hand, hold the string at about a right angle to the string gripper.
3.  Use the right hand to rotate the crank of the tension head clockwise. The linear ball bearing string gripper will grip the string while the tension head pulls the string.
4.  After the string gripper grips the string, the left hand could release the string.
5.  The left hand releases the string and the right hand continues rotating the crank of the tension head clockwise until the tension locking lever pops out.
6.  The tension head will be locked to the tension arm. This means that the Eagnas tension head has reached the correct tension
