Common Issues with Cordless Jigsaws

Cordless jigsaws are an essential tool for any DIYer or professional. They allow you to make quick, accurate, and precision cuts and are relatively easy to use. However, like all power tools, cordless jigsaws can experience problems from time to time. This section will cover some of the more common issues you may come across when using a cordless jigsaw, as well as a few simple solutions that can help fix them.

-Battery Not Charging: This is one of the most common issues with cordless jigsaws and can range from something as simple as a loose connection on the charger plug to a faulty battery pack or charger. To troubleshoot this issue start by checking the battery pack and plug connectors to make sure they’re making good contact with each other, and then check the actual charger for any signs of damage or corrosion. If none of those turn up anything, then it’s likely that either the battery or charger is defective and needs to be replaced.

-Blade Keeps Sticking: This usually occurs if debris has managed to get into the area between the blade and guide bushing where it will cause friction between them when moving in either direction resulting in a jerky quite motion when trying to cut straight lines. Disconnect power immediately if this happens so that you can safely inspect the area beneath.

Blade not cutting straight

  1. Blade not cutting straight is a common issue that can occur when using a cordless jigsaw. This problem can arise from a variety of causes, ranging from an incorrectly installed blade to worn or dull saw blades. To troubleshoot this issue, you should:
  2. Ensure the blade is correctly installed into the jigsaw by taking out the old blade and inspecting it for wear or damage before replacing it with a new one if necessary. After installation, tighten the blade so there is no movement or play in between the blade and the jigsaw body.
  3. Check the bevel scale on your cordless jigsaw to ensure it is calibrated accurately and adjusted properly for any angle you plan on cutting at; if not, adjust accordingly according to your manual’s instructions.
  4. Apply light pressure while cutting with steady strokes to ensure accuracy; and maintain a straight line when following certain patterns/cutting curves as opposed to using quick and erratic strokes which may result in uneven lines and poor cuts due to vibration from increased speed frequency.
  5. Ensure that what you are cutting along with your newly installed blade isn’t too thick for it; thin blades are best suited for thin materials such as wood veneer, plastic sheets etc., while thicker blades should be used when dealing with denser materials such as hardwood boards and metals.

Motor not starting

When troubleshooting why the motor of your cordless jigsaw is not starting, there are several likely culprits.

First, check the battery —ensure it is fully charged and properly inserted into the jigsaw. If that does not solve the issue, inspect to see if any part of the tool has become completely clogged with dust or debris.

You should also check to see if a belt or brush needs to be replaced since either of these components can cause the motor to fail.

Finally, look for an obstruction or foreign object preventing power from reaching the motor. Make sure that no object is obstructing any of the moving parts and that all vent openings at both ends of your cordless jigsaw are free of blockages before firing up your tool again!

Battery not holding a charge

If the battery of your jigsaw is not holding a charge, it could be due to various factors. Before troubleshooting, make sure that the issue is not with electrical power from the charger. Double check and ensure that the charger has been connected correctly to your jigsaw and is supplying power as required.

If the power on the charger seems to be fine, you should remove the battery and check for any visible signs of damage to ensure that it does not have a short circuit or any other defect which could be preventing it from charging. Also check if there are any visible signs of corrosion or dirt which might have affected its performance.

After ensuring the battery is not faulty, you can proceed to assess if there may be an issue with your cordless jigsaw’s circuitry or internal software built into its charger circuit board. Begin by removing all connectors on your cordless jigsaw such as wiring harnesses and encoder plugs on its motor unit before inspecting closely for any irregularities in assembly workmanship or wiring integrity. If needed, use an Ohm tester to confirm whether each component is working correctly without issue. This may include checking contacts points within your battery port, as well as testing voltage when disconnecting cables from their endpoints within the electronics board framework. Additionally take some time to check if there are any loose butterfly screws grounding each internal motor connection which could affect current continuity between separate components within the unit itself when conducting electrical tests such as checking for current continuity or wave resistance across contacts points in DC circuits where necessary – making sure that all levels are at satisfactory parameters before proceeding further with troubleshooting steps outlined below:

Troubleshooting Blade Issues

If your blade is not operating correctly, there are a few things to check before assuming there’s something wrong with the tool. Make sure the blade is properly installed. Any new work requires blades that are in good condition and securely inserted.

If all looks good, try lubricating the shaft of the blade where it connects to the saw using some oil. This will help ensure that you get the best possible performance from the tools and reduce vibration during use.

If the blades are still not working properly, it may be time for a replacement or service from a qualified technician.

Checking the blade for damage

  1. Checking the blade for damage: Start your investigation by inspecting the blade on your cordless jigsaw. If it has any nicks, dents, or other indicators of damage, you should replace it immediately. If not, inspect the bottom side of the blade to check for signs of wear and tear. Sometimes small pieces of material can cause friction and quickly dull blades. Make sure that the blade is properly tightened in its chuck to reduce vibration and ensure a clean cut each time you use it.

Adjusting the blade guide

If your jigsaw is not cutting straight, check the adjustable guide. This part is usually located near the saw blade and helps to keep the saw in a straight line. Many jigsaws have a set-screw device for adjusting it. Turning the screw clockwise will increase friction, and therefore, help keep the blade from veering off course. Too much pressure will slow cutting speed, so find an even balance between accuracy and speed that works for you.

To reset the blade guide after making adjustments, run your fingers over any exposed screws or bolt heads to ensure they are securely tightened before turning on your jigsaw. You should also check that all other components are correctly installed and functioning before proceeding with a project. If everything appears to be in good working order, move on to troubleshooting any motor or battery issues outlined in section C of this guide.

Replacing the blade

Replacing the blade is a simple process, but it is also crucial to cutting safety and accuracy. The following steps will help you replace your jigsaw’s blades correctly:

  1. Make sure the jigsaw is powered off and remove the battery or unplug from its power source. Place jigsaw on a flat work surface and remove the spark plug cover.
  2. If a blade lock system is present, these locks are easily accessed by unscrewing an Allen key or similar tool stored in the bottom of the handle grip. Once unlocked, you can now unscrew and remove the old blade with ease.
  3. Prepare the new blade by measuring its size against that of the old blade to confirm they are of equal size — some blades may have imperial measurements while others will have metric measurements, so either way check that they match up before proceeding further. You may even want to draw a circle around each saw’s blades for comparison if necessary as accuracy here is key!
  4. Push-fit or clamp fit saws require no additional tools for attachment – simply insert into corresponding slots until secure and repeat for other required slots (if applicable). If your model features an Allen key bolt system then please secure blades following instructions given in user manual before beginning use of saw again; always remember to tighten securely prior to starting work on project!


In conclusion, a cordless jigsaw is an incredibly powerful tool that can tackle a variety of tasks. From basic cutting and sawing to more intricate projects like plunge-cutting and trimming, the cordless jigsaw has the advantage of portability and the convenience of cordless technology.

As with all power tools, proper maintenance is key in order to ensure a long life for any cordless tool. Make sure to keep all brushes cleaned, blades sharpened and batteries charged — as well as inspect your saw frequently for any defects or performance issues. Keep track of your warranty information if something does go wrong so you can avail yourself of any customer service protections you may have with your purchase.

With these maintenance tips in mind, you can be confident with using your jigsaw that it will last many years without issue and provide excellent results every time you reach for it!
