Most modern hedge trimmers have blades that can be adjusted to four different positions. TheFileNumberET-18 positions are: level, left, right and 45 degrees (either left or right). The 45 degree position is used for cutting the tops of hedges at an angle.

The other three positions are used for cutting the sides of hedges. The ‘level’ position is used for vertical cuts and the ‘left’ and ‘right’ positions are used for horizontal cuts.

To adjust the blades of your hedge trimmer, first make sure that the trimmer is turned off and unplugged. Then, use a Phillips screwdriver to loosen the two screws that hold the blade guard in place. Once the screws are loose, you will be able to sliding the blade guard to the desired position.

Once you have adjusted the blade guard, tighten the screws back down so that the blade guard stays in place. Be sure not to overtighten the screws, as this could strip the threads or break the plastic.

Types of Blades

There are two types of blades on a hedge trimmer, and each type needs to be adjusted in a different way. The upper blade is the cutting blade, and is the only blade that actually does the work of trimming your hedges. The lower blade is called the counter-blade, and its purpose is to keep the cutting blade sharp by scraping away any debris that gets stuck to it.

The cutting blade is made of high-carbon steel, and is designed to be very sharp. The counter-blade is made of stainless steel, and does not need to be as sharp. Over time, the cutting blade will become duller and will need to be replaced. The counter-blade will also eventually need to be replaced, but not as often as the cutting blade.

To adjust the cutting blade, you will need a Phillips head screwdriver. First, loosen the two screws that hold the cutting blade in place. Next, rotate the cutting blade so that it is at a 45 degree angle to the counter-blade. Tighten the screws back down, making sure that they are tight but not over-tightened.

To adjust the counter-blade, you will need a flat head screwdriver. First, loosen the screw that holds the counter-blade in place. Next, rotate the counter-blade so that it is at a 90 degree angle to the cutting blade. Tighten the screw back down, making sure that it is tight but not over-tightened

How to Adjust the Blades

If the blades on your hedge trimmer are not cuttin g evenly, they may need to be adjusted. You can do this yourself with a few simple steps. First, make sure the trimmer is turned off and the blade is not spinning. Next, locate the adjustment screws on the blade. These are usually located near the base of the blade.

For Single-Sided Blades

Most modern hedge trimmers have a guard that protects your hands from the blades. The guard must be in place and properly positioned before you can adjust the blades.

The vast majority of single-sided hedge trimmers have what is called ” overload protection.” This means that if the blades get jammed, the motor will shut off automatically to protect both the motor and the operator.

To adjust the blades on a single-sided hedge trimmer, follow these steps:

1. Turn off the power to the trimmer at the main switch or circuit breaker.
2. Unplug the trimmer from its power source.
3. Remove the guard from the blade assembly.
4. Use a wrench to loosen the blade bolt (counterclockwise) until it is just loose enough to turn by hand.
5. Adjust the blade to your desired angle (usually between 15 and 30 degrees).
6. Tighten the blade bolt with the wrench (clockwise).
7. Replace the guard on the blade assembly and make sure it is properly positioned and secure.
8. Plug in the trimmer and turn on power at main switch or circuit breaker; test-run trimmer to check blade adjustment before resuming normal use.

For Double-Sided Blades

If your hedge trimmer has double-sided blades, you will need to adjust both the right and left blades at the same time. The process is essentially the same for both sides, but you will need to be careful not to adjust one side more than the other.

1. Start by loosening the bolts that hold the blade guard in place. You will need to use a wrench or a socket set for this.
2. Once the bolts are loose, you can remove the blade guard completely.
3. With the blade guard off, you should be able to see the adjustment screw on each side of the blades.
4. To adjust the blade, simply turn the adjustment screw clockwise to make it sharper or counterclockwise to make it duller.
5. As you turn the adjustment screw, you will see the blade moving in or out of position.
6. Once you have found the perfect position for your blades, simply tighten down the bolts on the blade guard and replace it on the hedge trimmer.


Now that you know how to adjust hedge trimmer blades, you can keep your hedges looking neat and tidy all year long. Be sure to follow the manufacturer’s instructions for your particular model, and always wear protective gear when operating power tools. With a little bit of care and attention, your hedge trimmer will give you years of trouble-free use.
