Fixing my Makita Jigsaw

I bought a Makita Jigsaw at a garage sale a few years ago, and when I tried to use it, the blade wouldn’t cut a straight line becuase the slider (thing that holds the blade) was so loose.  I put it in with my emergency tools (the ones you never use but don’t want to throw away).    Finally, I figured I should fix it or trash it, and opened her up.  This is what I saw, with the slide and gear removed for clarity.

The main items that were causing problems were the three metal pieces that you see at the bottom, two matched opposite each other, and the last a little to the left of the others.  YOU DON’T HAVE TO TAKE THE GEAR PIECE AND SLIDER OUT.  I did because I wanted to be clear

These three pieces hold the blade in place while it moves up and down.  They can wear out, and you can replace them.  Mine didn’t have too much wear, but the plastic slots that hold them were in rough shape.  They had obvious deformation that made it so they couldn’t hold the blade firmly.  I figured that buying a case would be too expensive, so I modified it.  I made sure the slides were clamped closely in place by shims.

I used the cedar shims you use for hanging doors and windows, because that was what I had around.

You can see the three slots that the “slider holders” should rest in.  I cut a thin shim and put in the bottom of each of these three holes.  The grease present in the bottom served to make sure that the shims would not fall out when I reassembled the saw.  These shims don’t have to be very thick at all.  Last of all, I shimmed behind the upper right “slider holder”.  This helped to remove the play in the other direction in the joint.

I then screwed the whole thing back together.  The play in the blade was gone.  If your metal slides are worn out, you can by replacements, and if you love the saw enough, you can buy a new body.  Given I already have another jigsaw, and wasn’t that far into this one financially, i just patched her up so I could use her.

Good luck, and thanks for any comments

    Great article – did you re-grease the working parts? And if so, what kind of grease did you use – does it have to be anything special?

    general purpose grease is ok, or to be more luxury the high temperature grease is better
