So if you’re looking for an answer to those pesky DeWalt 20V string trimmer troubles, then don’t go anywhere else – the solution lies here!
DeWalt 20V String Trimmer in General
String trimmers work by spinning the line at high speed and using centrifugal force to fling it against the edges of whatever grass or weeds they are cutting. As the line comes into contact with the object being trimmed, it cuts through it like scissors would. String trimmers can also be used to prune trees and shrubs, remove weeds from hard-to-reach areas, or even cut through thick brush.
In addition to its cutting power, a string trimmer is also very lightweight and easy to maneuver. Because it does not have the weight of a larger mower or tractor, most people are able to use one easily without any special training or experience. This makes them perfect for homeowners with small yards who need to maintain their lawns quickly and efficiently.
The DeWalt 20V String Trimmer is a great option for tackling tough outdoor tasks. This cordless trimmer comes with a powerful brushless motor, delivering up to 20V of power for maximum performance. With its adjustable speed trigger and variable speed control, you can easily adjust the cutting speed to suit any task. The automatic line feed system ensures no manual reloading is needed while the extended run time allows you to finish larger jobs without having to switch out batteries. [1]
Issues With the DeWalt 20V String Trimmer
Although the DeWalt 20V String Trimmer is a great tool for tackling tough outdoor tasks, there are some issues that can arise when using it. If not properly maintained and stored, the device can suffer from malfunctioning parts or even complete failure. In this section we will discuss some of the potential problems and how to fix them.
Trimmer refuses to start
One of the most common issues with the DeWalt 20V String Trimmer is when it refuses to start. This can be caused by a variety of factors, such as a dead battery, an issue with the spark plug, or even dirt and debris clogging up the system.
To troubleshoot this issue, first check that the battery is charged and in good condition. If it looks fine then try checking that the spark plug is properly connected and there are no signs of wear or damage.
You should also check if the battery itself is working by putting it into a charger and seeing if it charges up. If everything appears to be in working order then carefully inspect all filters and vents for any signs of dirt or debris – these should be cleared away if present. Finally, make sure all connections are secure before attempting to restart the trimmer.
Battery not charging
The next potential issue with the DeWalt 20V String Trimmer is battery failure. If the battery does not charge when connected to a power source, it may be due to a faulty charging cable or wall adapter. To check if the problem lies with either of these components, try using a different cable or wall adapter and see if that fixes the issue. If this doesn’t work, then it could be an internal hardware failure in the device itself which will need to be addressed by a professional.
You should also check whether the default battery charger has any power switch. If it does, ensure that the switch is in the correct position to enable charging. Additionally, make sure that the battery contacts are clean and free from any dirt or debris which could be preventing proper connection.
It’s important to take good care of your charger as it’s temperature sensitive and needs to cool off after each use. If the charger gets too hot, it could cause an internal malfunction in the device which will require professional repair.
You can also try resetting your battery. If this does not work, you may need to replace your battery as it is likely that it has reached its end of life.
Trimmer randomly turns off during working process
If the trimmer randomly turns off during use, it may be because of a faulty connection between the battery and the motor. Over time, dirt and grime can build up on these connections, causing them to become loose or worn out. The best way to address this problem is to clean both parts with a soft cloth and an electronic-safe cleaning solution.
Again, the battery may be the main issue here. Make sure the battery is in good condition, as a dead or malfunctioning battery can cause the trimmer to shut off unexpectedly. You should also check that all connections are tight and secure before attempting to restart the trimmer.
If you still experience random shut-offs while using your DeWalt 20V String Trimmer, it’s possible that there is an issue with one of its internal components. In this case, it would be best to take it to a professional for repair and maintenance.
Check your trimmer’s swath as well. If the swath is too wide, it may cause the motor to become overworked and shut off unexpectedly. Try narrowing the swath to see if that resolves the issue. You should also keep an eye on how long you work trimmer at a given time – try not to exceed 20 minutes of continuous use to avoid overheating or damage.
If these solutions don’t resolve your issue, then contact DeWalt customer service for help in troubleshooting further. In most cases, their knowledgeable technicians will be able to identify and fix any issues with your string trimmer quickly and efficiently.
Trimmer doesn’t perform at full capacity
Another common issue with the DeWalt 20V String Trimmer is that it may not perform at its full capacity. This can be annoying and can cause slower work, so it’s important to figure out what could be causing the problem.
This trimmer can reach up to 5800 rpm and has an internal speed regulator. If the trimmer is not reaching its full power, this could be due to a faulty or dirty switch on the motor. This can cause a decrease in performance, so it’s important to check and clean these parts regularly. You may also want to check that all connections are secure and there are no loose wires.
Additionally, if you experience any issues with noise or vibration when using the trimmer, it could be an issue with the line. You should never replace the line with one thicker than 0.095 inches as this can cause excessive wear to the motor and other components.
Trimmer vibrating
One of the most common problems with the DeWalt 20V String Trimmer is that it can vibrate excessively, resulting in an uncomfortable experience for the user. This can be caused by a number of things, including improperly tightened bolts and screws, worn or loose parts, and even dirt and debris getting stuck in the mechanism.
Luckily, this issue can be fixed relatively easily. First, inspect the line for breaks or frays and replace it if necessary. Then, check all the bolts and screws to ensure they are properly tightened. Finally, use a compressed air duster to clean out any dirt or debris that may be causing the issue.
Broken spools can also cause excessive vibration. If this is the case, you will need to replace the spool as soon as possible.
Jammed up Cutting Line
Another of the most common issues with the DeWalt 20V String Trimmer is a jammed up cutting line. This occurs when debris such as dirt, grass clippings, or twigs get trapped in the trimmer head and prevent it from rotating freely. To fix this issue you will need to take apart the trimmer head and remove any obstruction that is preventing it from spinning. Once cleared out, reassemble the trimmer head and test it to make sure that it spins freely without any obstructions.
Unfortunately, most of the time you will need to change the line if it has been damaged due to the obstruction. To do this, simply remove the spool from the trimmer head and replace it with a new one. Be sure to refer to your owner’s manual for instructions on how to properly insert the new line.
Overheating trimmer
The DeWalt 20V String Trimmer can be prone to overheating if not properly used or stored. If you are frequently using the trimmer, it is important to make sure you are allowing adequate time for the motor and battery to cool down in between uses. Additionally, it’s also important to store the trimmer in a dry and well-ventilated area when not in use.
If your trimmer has already begun to overheat, there are several steps you can take. First, unplug the device from its power source and allow it to cool down before attempting any repairs. If the problem persists after cooling down, you may need to replace worn or damaged parts such as switches, wiring, or brushes. It is also recommended to check the motor for dirt or debris buildup and clean accordingly. If you are still experiencing issues after replacing parts, it is advised to contact a qualified service technician for further assistance. By properly maintaining and storing your DeWalt 20V String Trimmer, you can ensure that it will continue to provide you with years of reliable performance. [2]
FAQ
How do you fix a trimmer that won’t start?
If your DeWalt 20V String Trimmer won’t start, there are a few steps you can take to troubleshoot the issue and potentially fix it.
First, check the spark plug for damage or debris. If the plug looks damaged, replace it with a new one. If it’s dirty, clean the spark plug using a wire brush or damp cloth and then dry it off before reinstalling it.
Next, make sure that the fuel tank is filled with fresh gasoline and that the air filter isn’t clogged or blocked in any way. Clean out any debris from around the filter and replace if necessary.
Finally, check that all of the cables are connected securely and properly. If any of the cables are loose, you may need to adjust them or replace them if necessary.
If none of these steps have solved the issue, it’s possible that you have a faulty carburettor and will require professional repair.
Why does my electric trimmer keep stopping?
Your electric trimmer may stop working for a variety of reasons. The most common reason is due to an electrical issue with the trimmer’s power source, such as a faulty battery or switch. If this is the case, you’ll need to inspect and potentially replace the battery or other components in order to get your trimmer running again. It’s also possible that the motor inside the trimmer has worn out, which can lead to it not turning on or staying on. To fix this, you will need to take off the cover of your trimmer and check if any parts are broken or need replacing. Finally, there could be debris stuck in between the blades preventing them from spinning—a good cleaning should do the trick!
In any case, it’s always a good idea to take your trimmer to a professional if you aren’t comfortable with performing any of the repairs yourself.
Is 20V enough for string trimmer?
The DeWalt 20V string trimmer is powerful enough to handle most trimming tasks, as long as you are careful with the amount of pressure you apply when using it. It can be used for light to medium-duty jobs such as trimming grass, weeds, and other small foliage. The motor is also designed to provide consistent power and efficient performance without bogging down.
However, if you have thicker or heavier material that needs cutting (e.g., shrubs or larger branches) then the DeWalt 20V may not be powerful enough. In this case, you may need to consider a higher voltage option like the Dewalt 40V string trimmer. The 40V model has a maximum wattage output of 2,400 watts and can take on tougher trimming tasks with ease.
Overall, the 20V DeWalt string trimmer is ideal for light to medium-duty trimming jobs around your yard but may not be powerful enough if you need to tackle thicker material or larger branches. If this is the case then it’s best to choose a higher voltage option like the 40V DeWalt String Trimmer.
How long does the Dewalt 20V trimmer last?
The Dewalt 20V trimmer is designed to last a long time. With proper care and maintenance, you can expect the trimmer to last for several years. To extend the life of your trimmer, make sure to always use fresh string and clean the unit regularly.
Also, try to avoid running the trimmer for extended periods of time as this will put additional strain on the motor and reduce its longevity. Following these simple steps should help ensure that your Dewalt 20V trimmer lasts for many years to come.
Why does my string trimmer keep jamming?
A common problem with string trimmers is that they can become jammed due to a variety of factors. The most common reason for this is an obstruction in the line, such as grass clippings or dirt, which can cause the line to break off and jam up inside the housing of the trimmer. Additionally, if the line isn’t properly loaded onto the spool and tensioned correctly, it may not move freely through the housing and could become jammed. Finally, over time, wear and tear on parts like bearings or gears can result in a lack of free movement that also causes jamming.
To help prevent jams from occurring, make sure you regularly inspect your trimmer for obstructions and ensure that your line is properly loaded onto the spool. Additionally, you should inspect and replace any worn out parts on a regular basis to keep your trimmer working smoothly. If you do find yourself with a jammed trimmer, try checking for obstructions or replacing the line before taking it into a repair shop as this could save you time and money.
