How to Attach Blades to Dog Clippers?

Attaching a blade to your dog clippers is simple. Align the blade with the clipper head and click it securely into place. Ensure that the clipper is turned off before handling the blades to avoid any accidents.

How Do Hair Clipper Blades Cut?

Clipper blades cut hair using a back-and-forth motion, with the top cutter moving side to side against the bottom rail. The smooth movement allows for a precise, clean cut as the motor powers the action, ensuring an even trim.

How to Adjust the Tension on Hair Clipper Blades?

To adjust the tension, use a flathead screwdriver to turn the tension screw on your clipper. The blade should move smoothly but not be too loose, as this can cause pulling or uneven cutting. Test the adjustment on a small area first.

Signs Your Dog Clipper Blade Needs Replacing

If your clipper blade is dull, it may tug at your dog’s fur or cause discomfort. Other signs of wear include rust, chips, or irregular cuts. When sharpening no longer restores the blade’s effectiveness, it’s time to replace it for optimal performance.
