Hedge trimmer blade sharpening
Step 1- Wear hearing and eye protection help prevent damage, as the power grinder will generate sparks. If these sparks get into the eyes or ears during the sharpening process, they may become permanently damaged, even causing you to become blind or deaf. Wear a protective face cover if you can, and flame-retardant clothing. Certain materials are more likely to catch fire, so be sure you are not wearing anything extremely flammable. Be hazardous of fire. It is always suggested to perform this method earlier in the day to be able to see any smoldering cinders. When using this method, it is important to remember to have a source of water nearby, in case of actual fire. Step 4- Apply light pressure to ensure a good edge. To prevent over sharpening the tooth, use short strokes. Long strokes almost always ensure an unevenly sharpened blade. No matter how good your hedge trimmer is, you will need to sharpen the hedge trimmer blades from time to time. Statistics suggest that you need to sharpen the hedge blades after every 50 hours of work. Sharpening ensures the removal of any residue that accumulates on the blades over time. Hedge trimmers are mainly used to reduce work while preserving impressive landscapes and yards. Keeping their blades sharp helps them to maintain optimal performance. Owners of hedge trimmers can save money by sharpening their blades at home. Here are two methods of sharpening your hedge trimmers: Push down on the mill file while guiding it along the edge of the tooth to the tooth's point. Brush the cutting teeth with a nylon-bristled brush, removing all dirt and debris that can interfere with the file and blade. Reposition the file in the groove on the opposite side of the tooth, keeping the file flat instead of at an angle. Guide the file flat along the tooth to the point. Align a 10-inch mill file in the groove of the first cutting tooth you want to sharpen, angling the file so it follows the original factory bevel. Hedge trimmers are filed at an angle on only one side of the metal until sharp, with the other side remaining flat. Next you will want to use the sharpening stone. This tool works to remove any kinks or bumps in the metal. They may cause snagging and create an uneven cutting edge. These kinks will often be on the underside of the blades. So you will need to work carefully and thoroughly along the edges to ensure you remove them all, taking care not to hurt yourself. Getting rid of them is important. It keeps the mating surface between the opposing blades smooth and reduces the chance of them catching on each other. The following step is to take a damp rag and wipe down each blade carefully, removing any residue and leftover filings; while they are only small, they could clog up and damage the trimmer if you leave them on the blades. Getting rid of sap-build up, twig fragments, and anything else that has been caught between the blades is also important to the overall functionality of your hedge trimmer. Finally, give the blades a thorough spray with machine oil or a manufacturer-recommended lubricant to prevent rust and to keep them moving smoothly. Firstly, before you begin sharpening, it’s very important to make sure that the trimmer’s upper and lower blades are in correct position. They have to align with each other, so that you can access both. Do this by gently squeezing the blades together, ensuring that the top blades rest exactly over the lower ones. You can use the head of a screwdriver to get the alignment perfect. Of course, its only if you can’t do it with your hands. Second, you will also need the proper sharpening equipment. Flat file and a sharpening stone, as well as a flat surface to place the blade on. First of all, check the manufacturer’s guide for specific instructions regarding the angle at which to file the blade. Afterwards take your file and begin working on the first blade tooth. You should hold your file at the same angle as the edge you are working on, sliding it downwards towards the point of the blade. The blades are made up of three cutting edges. There is one on each side and also one at the tip. So it’s important to work on all three by turn, making sure each is sharp. The edge of the blade should become shiny as it gets sharper. So it’s easy to tell whether the file is effective and whether you’re making progress. Above all, make sure you do not file away too much of the blade. The wear threshold is 5mm. If you file away more than this, the material may lose strength.
The hedge trimmer’s performance will also be negatively affected if you vary the force when filing, as this will lead to blades of different lengths. To ensure long-lasting cutting performance, follow these two steps. First of all, a flat file can be used.
Make sure that the upper and lower blades come to rest at the same position. This simplifies the filing process.
Always file in the direction of the cutting edge. This is how the flat file is designed to work and guarantees an optimum cutting edge. Try to maintain the specified sharpening angle. This can be found your equipment’s instruction manual under “Specifications”.
Only sharpen the blade downwards in the direction of the cutting edge. Ensure the file is not in contact with the blade when pulling back upwards, or the blade will become blunt. Ideally, you shouldn’t wait until the blades are showing signs of serious wear before sharpening them. The blades should be sharpened regularly after about every 50 hours of operation to maintain cutting performance.
When cutting back branches in hedges, sap and resin residue gathers on the hedge trimmer blades. Remove any dirt before sharpening, otherwise you could damage the file and the stone.
As a rule of thumb, only sharpen the cutting edge. Ensure that the file does not come into contact with the integrated cut protection or, in the case of professional hedge trimmers, the orange plastic cut protection. For the second step, remove the burr from the bottom of the blade using a sharpening stone. It is also a good idea to perform this and other spark-generating repairs earlier in the day to give you time to catch any potentially smoldering cinders left behind. [Back to top] 2. Secure the bar of the hedgetrimmer with a clamp. Hold the surface of the grinding wheel against the surface of each tooth edge at the same angle as the tooth edge. Sharpen all three top surfaces of every hedgetrimmer tooth along the bar. Using the screwdriver end as a pry bar, adjust the blades until they are perfectly aligned with one another. [Back to top] Repeat the same process for the topside of each tooth surface, always making downward stokes with the file at the same angle as the tooth edge. Ensure that the upper and lower blades are perfectly aligned when the trimmer is switched of and use the file to sharpen in a downward direction (towards the sharp edge). To ensure the trimmer will continue to perform as expected it’s worthwhile checking the manufacturers instructions to make sure the angle you file the blade is as per their specifications. Once you’ve finished filing one blade tooth, turn the trimmer over to file down the opposing blade tooth. You’ll know the blade is properly sharpened when the apex where the two blades meet is razor sharp The primary purpose of this tool is to remove or ‘deburr’ kinked metal from the underside faces of the blades. If the mating face between the blades is not perfectly smooth this can have a detrimental effect on the mechanism and reduce the effectiveness of the trimmer If you’re a real stickler for a well pruned hedge chances are you find yourself in the garden regularly trimming yours. No matter what hedge trimmer you use, a budget electric or high end petrol model, there’s no getting away from the fact that hedge trimmer blades need sharpening once in a whole to keep them cutting effectively. Naturally the more you trim, the more frequently you’ll need to sharpen too. You’ve got two choices when it comes to sharpening hedge trimmer blades, you can either do it yourself, or pay a professional to do it for you. If you’re not at all comfortable doing it yourself we’d stick to handing it over to someone that knows what they’re doing, however if you do have the confidence and inclination it’s an easy way to save a few pennies. Align a 10-inch mill file in the groove of the first cutting tooth you want to sharpen, angling the file so it follows the original factory bevel. Hedge trimmers are filed at an angle on only one side of the metal until sharp, with the other side remaining flat. Place the file back in the original position on the first side of the cutting tooth. File the tooth a total of 10 to 20 times on each side of the cutting tooth, alternating sides with each pass, until the tooth has a sharp edge. It may take even more than 20 strokes to file down a nick, but 10 to 20 strokes are all that are needed to sharpen dull, rusty blades. Set the Black and Decker TR250 hedge trimmer on a flat work surface that allows access to the cutting bar and teeth. Stabilize the bar in a table vise, if desired, so it doesn't move while you work. Unplug the trimmer from a power source. As long as the trimmer is unplugged, no need exists to disconnect its spark plug to prevent accidental engine firing. Reposition the file and sharpen the remaining teeth along the bar, using the same techniques you used to sharpen the first tooth. Try to file each tooth the same as the rest of the teeth on the trimmer. Find a flat surface to work on. Unplug the electric hedge trimmers and place them on the table top with the blades facing away from you. poinsettia hedge 3. image by mdb from Fotolia. com Test for sharpness by holding a piece of paper above the blade. Without using a lot of force, bring it down across the blade. If the paper does not cut easily, repeat the sharpening process. Apply a thin coating of linseed oil over both sides of the blades before you bolt them back together. This will keep them from rusting. One of the important benefits surrounding hedge clipper sharpening procedures is the extension of blade life. Extending blade life allows for an extended life for the overall product because sharp blades reduce the work load of the electric motor or gas engine. Sharpening of edge clippers is relatively easy but time consuming. Most hedge trimmers have four cutting edges per blade inch. The industry standard is 1.16 edges per inch. As an example, the common 22″ hedge trimmer has a minimum of 102 cutting edges to sharpen. Hedge trimmer sharpening ensures the removal of any residue that accumulates on the blades over time. Keeping their blades sharp helps them to maintain optimal performance. I keep my blades lubed with motor oil and multi-purpose household oils, not wd-40. wd-40 is a moisture displacement substance and not a particularly good lubricant.

Set Tips $2.00 It was over 100 degrees in my shop when I started sharpening this hedge trimmer so I elected to relocate to my back patio where it was only about 90 degrees or so. A quick inspection of the trimmer showed that they were in pretty good shape overall. Only one cutting edge had a small chipped edge. The lower reciprocating blade was bent downward from the top blade but only effected the cutting of the first pair of teeth on the blade which is seldom used. So, I adjusted it slightly and started sharpening. Mr Bart, thank you for your business. If you do pick up you oil and oil can, take it with you when you go to trim your hedges. Just a wee bit of oil every once in a while will make your work go faster and make your trimmer last longer. If you are in the Semmes Alabama area, you can pick up the file at Ace Hardware at 7380 Moffett Road. They have everything you need, are great people and I want to thank them for the many referrals they send every year. Their phone number is 251-645-1001. If you are happy with my work, please leave reviews at: Sharpening hedge trimmers takes a little time but it gives instant gratification when you see that shiny sharp edge appear from beneath the dull crusted teeth.

Either way, here is how I’d do it: Remove the bolts that hold the blades together and clamp them into a bench vice. Of course, whenever you use a power tool you will want to be wearing the appropriate safety gear – hearing protection and eye protection. To finish all you need to do is continue with that same process on each tooth all the way down the bar. Place your hedge trimmer in a vise. If you do not have a vise, you can ask someone to hold it for you while you work on it. Spray with WD40 to add shine and strength to your blades. Or dip in a bucket of hot, soapy water to remove sap from your blades. Most new Black & Decker tools come with warranties for up to two years from purchase date. But if you really want to get your money’s worth, simply take good care of your equipment and re-sharpen as necessary. Black & Decker hedge trimmers can last for decades if properly maintained. Sharpening the blades yourself is much more affordable than buying new blades or a new trimmer. Unplug the trimmer before adjusting the motor or going near the blades.
