Depth Setting

[Bob B]

I have a Makita 5007NB circular saw. The lever that locks the depth of the cut doesn't lock down. I may be in the middle of a job and the saw will not hold the depth of cut I have set. I've fooled around (trial & error) trying to get it to firmly hold the depth of cut setting without reliable results. I'm wondering if there is a cam in the lever assembly or if replacing a series of components will restore reliable use. The blow up on the website shows parts that may be involved [37-41, 54, 56] but I can't see if they may be the solution. Meanwhile, I'll try Mark's suggestion to John's Loose Shoe question. - More trial & error?

Thanks.

I am having the exact same lever-lock problem with my Makita 5007NB and would like to know if you found the solution or which parts you needed. Thanks.

I had the same problem with a slipping depth lock. What worked for me:

Remove P.H. Screw #38 in above diagram and remove LOCK PLATE #39.
Slightly tighten HEX NUT M8 #37 (this takes some trial and error to find the right setting.
Replace LOCK PLATE #39 and hold in place with thumb as you test the depth lock. (The first time I over tightened the HEX NUT.)

After you have properly positioned the HEX NUT & LOCK PLATE, replace P.H. Screw #38.

By the way, if you are using the original power cord, you might want to remove the handle cover #19 to check the insulation. The individual hot & neutral wire insulation on my saw had dried and cracked, however the internal wiring was fine.
