Problem 1: The Blade Keeps Falling Out

The reasons that can make your jigsaw blade fall out are:

  • Sawdust buildup within the blade holder can obstruct proper insertion. 
  • Worn-set screws might fail to secure the blade effectively.
  • Using the wrong blade type for your machine can lead to instability.
  • If your jigsaw is worn out, it may be time to consider a new one.


  • Checking Blade Holder: 

Inspect the blade holder for sawdust accumulation. Clear any blockages to ensure a snug fit. 

  • Assess the Condition of the Set Screws: 

Worn threads could prevent them from securing the blade correctly. Consider using star or spring washers if screws tend to vibrate loose.

  • Using Appropriate Jigsaw:

Confirm that you’re using the appropriate type of jigsaw blade for your machine. This is a common issue, so make sure you understand the distinction between U Shank and T Shank blades.

If the problem persists, it might be time to evaluate the overall condition of your jigsaw. If it’s worn out, investing in a new jigsaw with T Shank compatibility is advisable.

Problem 2: Table Not Level at 0

The issue the M18 Fuel jigsaw table is not level at 0 can cause inaccurate cuts. Despite your efforts, the saw consistently produces uneven and non-square cuts, even on 2x4s. It can lead to unnecessary frustration and wasted materials.


To address this problem,

  • It’s essential to first confirm whether the table is adjustable. If it is, try to recalibrate it to ensure it is perfectly level at 0 degrees. 
  • Consult your tool’s user manual for specific instructions on how to make this adjustment.
  • Invest in high-quality blades that are less prone to bending, as blade flexibility may contribute to your cutting issues. 

However, keep in mind that jigsaws are primarily rough cutting tools and may not provide perfectly square cuts on thick materials like 2x4s. Consider using alternative tools, such as a miter saw, for precise and square cuts on such materials to achieve the best results.

Problem 3: Alignment Issues

Many users of the Milwaukee M18 Jigsaw have faced alignment issues with their saw blades. The blades tend to become skewed, making it challenging to achieve straight cuts. 

Users have to hold the saw at an angle to compensate for the misalignment. It is not only inconvenient but also affects the quality of their work.


If you’re experiencing alignment problems with your Milwaukee M18 Jigsaw, there are a few potential solutions to consider. 

  • First, ensure that you are correctly inserting the blades into the collar and pushing them all the way in. Improper blade installation can lead to misalignment issues. 
  • Additionally, be aware that jigsaws, in general, may not cut thick materials perfectly square, especially when cutting quickly. 
  • If the problem persists despite correct blade installation, you may want to check for any loose parts, such as the shoe plate, and tighten them if necessary.

If all else fails, you may need to consider exchanging the saw for a new one, as some users have reported success with this approach. 

Problem 4: Motor Failure

The M18 FUEL Jigsaw can face a motor failure issue. Despite receiving power (indicated by the LED light), the blade remains stationary when a battery is attached. Also, if the jigsaw is used for extended periods or in high temperatures, the motor may overheat and fail.  


To address this problem,

  • The user should first ensure that the jigsaw switch is set to the “unlock” position. 
  • If it’s in the “lock” position, the blade won’t move. 
  • Additionally, trying a different battery may be helpful, as a faulty battery could be the root cause. 
  • If the issue persists, it might be due to a blade binding problem. Slightly pulling the blade and then attempting to use the jigsaw could resolve this. 

If none of these steps work, considering warranty options or seeking professional assistance is advisable. Remember, safety is paramount when troubleshooting power tools, so always follow manufacturer guidelines.
