Electric hedge trimmers are a popular tool for maintaining and shaping hedges. To keep them in optimal condition, regular sharpening is essential. Here are the steps to sharpen electric hedge trimmers:
1. Safety first: Before sharpening, always disconnect the trimmer from the power source and wear protective gloves and goggles.
2. Clean the blades: Remove any debris or sap from the blades using a brush or cloth.
3. Remove the blades: Most trimmers have a blade lock or release button. Follow the manufacturer’s instructions to safely remove the blades.
4. Sharpen the blades: Use a sharpening stone or file to sharpen the blades. Follow the original angle of the blades and make smooth, even strokes along the cutting edge.
5. Check for balance: After sharpening, make sure both blades are balanced. If one blade is heavier, it may need further filing.
6. Reassemble and test: Put the blades back on the trimmer and tighten any screws or bolts. Test the trimmer to ensure it’s cutting smoothly and efficiently.
Regular sharpening will not only improve the performance of your electric hedge trimmers but also extend their lifespan.
Electric hedge trimmers are efficient tools for shaping and pruning shrubs, but they require occasional sharpening to ensure optimal performance. Sharp blades enable clean and efficient cuts, resulting in well-groomed hedges. It is important to refer to the owner’s manual for specific instructions or product recommendations before following the standard sharpening tips.
Indications for Sharpening Hedge Trimmers
Typically, you can tell that it is time to sharpen your electric hedge trimmer when it starts to perform poorly. With each cut, the blades gradually become dull, necessitating sharpening. Signs that the blades need sharpening include the trimmer grabbing the branches instead of cutting them smoothly or producing ragged cuts. Generally, it is advisable to sharpen the blades after approximately 50 hours of use, although it is important to watch out for other signs of blade dullness as well.
Cleaning the Teeth of the Hedge Trimmer
After cutting through various bushes and shrubs, the trimmer’s teeth may become covered with sap, resin, dirt, and other debris, which can hinder cutting performance. Additionally, it becomes challenging to sharpen the blades if they are dirty and coated with grime. Prior to cleaning and sharpening the tool, it is essential to wear safety goggles and work gloves for personal protection.
Use a soft cloth to wipe away debris from the teeth. If sap or resin cannot be removed with a damp cloth, consult the owner’s manual for cleaning solution options. Typically, soapy water is safe to use, but it is crucial to thoroughly dry the blades and lubricate them after sharpening to prevent rusting.
Filing the Blades of the Hedge Trimmer
Before sharpening the blades, ensure that the upper and lower blades are properly aligned. Use a flat file and align it with the cutting edge angle of the blade. File in only one direction, moving towards the cutting edge before lifting the file and returning it to the starting position.
Continue this motion to remove just enough blade material for sharpening. It is important not to file off more than 5 millimeters of material, as excessive removal can weaken the blade. Maintain consistency by counting the number of strokes made with the file and using the same number of strokes for each blade.
Removing Burrs
Sharpening the blades can leave behind burrs that need to be removed to prevent quick dulling. Burrs are typically found on the bottom side of the blade. A whetstone can be used to smooth out the burrs.
This step is easiest if you turn over the hedge trimmer. Lightly moisten the blades and use a swiping motion, following the direction of the tip as a guide. Repeat this process on each blade to eliminate the burrs.
Cleaning the Hedge Trimmer
Your hedge trimmer is now almost ready for trimming hedges, but it requires a final cleaning. Use a soft cloth to wipe away dust and debris from sharpening the blades and removing the burrs.
The final step is to lubricate the blades, which helps prevent rust. Refer to the manufacturer’s recommendations for the appropriate type of oil or lubricant for your model. Generally, using 3-IN-ONE multipurpose oil is safe for any hedge trimmer.
