How to Adjust the Tension
of your Shear & Thinner
Your shear or thinner has been carefully adjusted for optimal performance. When you feel that they need adjustment, please follow these simple steps:
Hold shear/thinner at 30° angle with the tip pointing up & to the left. Continue holding at this angle throughout steps 1-5.
With one hand, hold the shear by the bottom handle hole. With the other hand, lift the top hole by the finger rest until the mouth of the shear/thinner is opened at about 60°.
Release the top handle & let it drop down freely. The shear should close & stop by itself right before it is completely closed, leaving a 1/4” gap between the tips. This is the optimal position for correct blade tension.
Top of shear will close quickly, sharply, “heavily” & all the way closed.
Top of shear will not move at all when you release it or drops down just a little bit. Adjusting the dial too tightly will damage your shear or thinner.
If it requires adjustment, turn dial (either with fingers or tool depending on model) clockwise for tighter & counter-clockwise for looser. Make adjustment in very small increments, at each turn you will hear a slight “click”.
