If so, please can you tell me how to adjust the dose.  I faff about every year and usually end up with the blessed springs in my hand which are then a real pain to get back to where they are supposed to be!  I'm trying to increase the dose if that makes any difference!

Thanks

The screw inside the handle , you just slacken the lock nut and turn the screw to adjust .   the one for the spring is just to adjust the pressure of the moving handle to suit the person using it .
