How to Sharpen a Tree Trimmer
- 1). Secure your tree trimmer to your workbench. You want the blades to be hanging over the open air and the rope and pole to be out of the way during the sharpening process.
- 2). Assemble your hand drill with your sharpening bit. If you have an adjustable speed drill, use a medium speed.
- 3). Wet the sharpening bit with a light coat of water. This will prevent the blade or bit from heating up and warping.
- 4). Sharpen the top face of your small blade using the hand drill with the sharpening bit. Hold the trimmer with your left hand and the drill with your right. The drill should be at a 30- to 45-degree angle.
- 5). Continue until sharp. Do not heat up the blade as it will become brittle and break. Pay attention to metal burs that need to be removed.
- 6). Wipe the blade and all moving parts with a light oil to lubricate and protect them.
