A step-by-step, detailed guide

The types of hedge trimmers

Hedge trimmer(€ 77.00 at Amazon *) is not the same Hedge trimmer. Basically, two types can be distinguished: the manually operated hedge trimmer and motor-operated hedge trimmer that is connected to an energy source.

Manually operated hedge trimmers

Manually operated hedge trimmers look like oversized ones Secateurs(€ 12.96 at Amazon *) with a very long handle and longer, straight cutting edges. Sharpening also works in a similar way to one Secateurs and is significantly faster than sharpening other types of hedge trimmers.

Motorized hedge trimmers

There are basically three common types:

• Petrol hedge trimmer
• Electric hedge trimmer
• Hedge trimmer with battery

For sharpening, it doesn't matter where the energy comes from; the cutting blades are very similar in all three cases. The cutting blade has numerous points, each of which must be sharpened individually. The work is therefore a little arduous, but it is worth it. It is important that you remove the energy source before sharpening so that the hedge trimmer cannot come on.

Sharpen motorized hedge trimmers

1. Caution comes first

First of all, make sure that the hedge trimmer cannot start under any circumstances. To do this, pull the plug from electric shears, remove the battery from hedge trimmers with a rechargeable battery and pull out the spark plug from petrol hedge trimmers.

You should also wear gloves to protect yourself from injury. Safety glasses can also be useful.

2. Optional: disassemble the hedge trimmer

If you can remove the cutting blades of your hedge trimmer from the holder, this has several advantages: You can use both cutting blades sharpening is much more thorough and easier and you can thoroughly clean both cutting blades and hedge trimmer bodies - both inside and out Outside. We will explain to you how to dismantle your hedge trimmer in this article.

When you've disassembled your hedge trimmer, place a cutting blade on a block of wood for sharpening and work on the part that protrudes beyond it.

If you don't disassemble your hedge trimmer, fix it as you can, e.g. B. with a vice.

3. Sharpen cutting blade

Now place the file on the top prong and file from top to bottom. Moving back and forth is not a good idea; always file smoothly and evenly in one direction. Pay attention to the right angle! 15 to 20 movements per side should be enough. Then move on to the next prong and file all of the prongs on the exposed side in one direction.

4. Sharpen the other side

If you have not disassembled your hedge trimmer, now is the time to do the following: Reinstall or replace the spark plug or battery. connect the hedge trimmer to the power supply. Turn them on for a moment and pause where the prongs obscure the side you've already sharpened.

Now file the other side. Do not turn your hedge trimmer horizontally! It is not about the back but the opposite side of the prongs, so to speak right and left, which was previously covered by the second cutting blade.

If you have disassembled your hedge trimmer, you can simply sharpen the entire point straight away.

5. Clean the cutting blade on the reverse side

This step is only possible after you have disassembled your hedge trimmer, turn the blade over and file down the entire surface to remove dirt and any rust.

7. Clean

If you have disassembled your hedge trimmer, rub the shaft on which the cutting blades are attached with some sandpaper. Then spray or rub both cutting blades and the shaft with a little oil and rub everything off with a dry cloth.

Otherwise, just spray the cutting blades with oil and remove any residues from the files with a dry cloth.
