How to Change the Comb and Cutter on a Shearing Handpiece

As any shearer will tell you, sooner or later the comb and cutter on a shearing handpiece is going to go blunt. Sheep’s wool is not only thick but can be packed with dirt and debris, all of which tends to blunt the cutting edges as time goes on. Blunt blades won’t get you very far, though, so here are some quick tips on how to change the comb and cutter so you can get back to work.

1. Loosen the tension screw to slacken off the tension
2. Turn over the handpiece to access the retaining screws holding the comb and cutter in place
3. Use a shearing clipper screwdriver to loosen the retaining screws, just enough to be able to slide out the components but not so loose that there’s danger of them falling out onto the ground or into a pile of dirt
4. Gently remove the comb, and then the cutter, placing them safely to one side

Depending on the handpiece model, this is a good time to add a few drops of oil to the moving parts of the mechanism to keep it running smoothly and efficiently. If your model allows, place a few drops of oil into the oil hole on top of the handpiece.

5. Next, loosen the screws to allow the new parts to slide in easily
6. Slide the new comb into place
7. Turn over the handpiece and slide the cutter into place
8. Line up the cutter and fit into any holding mechanism
9. Move the throw so the tip of the cutter is on the right hand tooth of the comb
10. Adjust the lead to reach the required depth
11. Turn over the handpiece keeping everything in place and tighten the retaining screws
12. Tighten the tension screw until it becomes tight enough to stay in place without overdoing it

The comb and cutter that have been removed will be blunt and dirty. Clean them carefully with warm soapy water and then leave them somewhere safe to dry out. Once dry they’re ready to be ground to get them sharp again.

Combs and cutters that are too blunt to cut wool effectively are still sharp enough to do serious damage to hands and fingers. Take extra care whenever you’re working around any electrical tools, especially ones with blades or cutting surfaces.
