Jigsaw saws are a common tool in the workshop. They have been around for decades and have been used to cut plywood, drywall, metal, and other materials. As a result of this widespread use, jigsaw users encounter many problems that need fixing. This blog post will focus on some of these common issues with jigsaws and how they can be fixed quickly and easily.
Common Jigsaw Problems and How to Fix Them
Problem 1: Jigsaw is cutting very slowly
If your jigsaw is cutting slowly, this could be caused by a couple of things: either the blade has become dull and needs to be replaced with a new one OR you are not pressing hard enough on it. Make sure that you fully press down on the trigger and maybe even hold it down as you cut. The more pressure that you apply, the faster it will go!
Problem 2: Jigsaw slips around as I am cutting
Some jigsaws come with an adjustable shoe that allows for easy adjustment of how far away from the edge you want to cut. If your jigsaw does not have this feature, make sure to clamp down your workpiece at both ends so that it doesn’t slip around while you are cutting. If your piece is still slipping around, try changing the blade to a higher tooth count blade for smoother cutting.
Problem 3: Jigsaw shoots my workpiece off the table and I keep having to chase it down
The jigsaw is designed so that the base of the saw will shoot off from underneath your piece while you are cutting. This helps to give a clean-cut by allowing for a clean break on both sides of your workpiece, rather than just one side. You can add some slight downward pressure with your hands while you cut down along this edge to help hold it down while you go through it. If you have some concerns about adding too much downward pressure with your hands then clamp a board underneath of your workpiece at an angle pointing away from where you are going to be making your cuts.
Problem 4: Jigsaw isn’t cutting straight
This is mostly an issue with the guide. If you are having issues with your saw cutting at a weird angle, first check to make sure that the guide isn’t bent or damaged in any way. Remove it and look it over to see if there are any dings or bends on it before putting it back onto your jigsaw. Also, recheck that the blade is lined up properly within the slot of the guide (if there is one). Sometimes these can become misaligned, which will cause your jigsaw to not cut/guide very accurately!
One quick fix for this problem is to take tape (masking tape works best) and mark where either end of your shoe meets the guide rail along both vertical rails at both ends. You want the paint on the tape to be on the same side on each rail, on both sides of your shoe (i.e., if there is a piece of tape between the right vertical guide and the bottom blade mounting slot, then there should also be a piece of tape between that bottom blade mounting slot and the left vertical guide that is on the exact opposite side). Then simply line up these pieces of tape with their counterparts at both ends, one horizontal pair for each end of your jigsaw! Now you can get back to making accurate cuts like before!
Problem 5: Jigsaw is vibrating
There are three ways to fix this problem. The first way is to be extremely careful when making cuts and use extra pressure on the handle of the saw; most likely this will make the problem worse. The second way is also to be very careful but move slower; same reason as above. The last way is to balance the blade… simply take a good look at how your blade lines up with your shoe, and adjust accordingly (by putting lead weights or fishing weights on either side/end of the saw).
Problem 6: Jigsaw has too much friction
Make sure you’re following along: you should have a shoe attached to your saw, and you should have already cut out the shape of the bottom of your blade.
As you might have guessed, this is another one that’s pretty self-explanatory. There’s a lot of friction between your blade and shoe! You’ll see a lot of resistance while trying to cut out the shape. To fix this problem, you can sand down either surface (the shoe or the saw). The best thing would be to take it slow when cutting so you won’t have to do any sanding at all! Problem 7: Drawer slides in the wrong direction
Problem 7: Sawdust clogging up
This could be because there’s too much sawdust building up on your shoe. Dust might get lodged onto the shoe while cutting out your design which would prevent the bit from moving freely and may cause problems later. Putting a piece of cloth or paper towel under can help prevent this problem for future use (although I don’t know why somebody wouldn’t clean their jigsaw before using it). You can also put a pencil lead or a piece of wood onto the shoe to increase friction and lessen the sawdust from building up on your shoe.
Problem 8: Your blade isn’t feeding correctly
If your blade is not feeding into your material when starting the cut, it may be because you’re not pressing down hard enough on the jigsaw’s footplate. The foot of your saw should be pressed firmly against the material so that it doesn’t slip while cutting through it!
Problem 9: Jigsaw quits after a few seconds.
An issue that occurs with some jigsaws is their lack of power. If you’re cutting through a material and the saw just quits, try to find an extension cord that’s as long as possible, or use a rechargeable power drill or impact driver instead so that you don’t have to worry about power sources.
Problem 10: The temperature of your blade jumps up excessively.
If your blade heats up too much during use, try putting a fan on it so it cools down more quickly. You also need to ensure that there are no bolts stuck in the shoe plate because they may have fallen out while transporting your tool, which will cause the blade to heat up when used since it is loose.
If you’ve ever had trouble with your jigsaw, I hope this blog post has helped. I covered how to fix common jigsaw problems. Hopefully, this is helpful for you if you have one or more of these issues!
