How do I use the different springs to change how hard I have to squeeze?
To change the amount of resistance that you squeeze again, simple change the spring that you use as follows:
| 
 Strength of resistance  | 
 Slot 1  | 
 Slot 2  | 
| 
 1  | 
 Standard  | 
 
  | 
| 
 2  | 
 Standard  | 
 Standard  | 
| 
 3  | 
 Standard  | 
 Strong  | 
| 
 4  | 
 Strong  | 
 Strong  | 
Slot 1 is nearer the hinge, slot 2 is nearer the tip
