Thanks for posting I just fixed my DCS387 Sawzall I’ve had it for over six years thought I lost it after it got wet, till I found this video. different model, but same concept I was able to follow through with similar steps. Great video. Saved me $200 on a new one 👍🏽
I used my reciprocating saw and jigsaw last to cut wood to build my 2 chicken pens. I love my tools and blow them and oil the blads but as a woman I did not know what to do for the inside till now. Thank you so much and congrats on his tool working I was excited lol
Excellent video, very well detailed. Being that I own at least 20 Dewalt tools I have to take them apart for maintenance quite a bit, but to be fair we beat the hell out of them and am satisfied with their performance. Was always a Milwaukee guy but my brother bought me a huge Dewalt kit for Christmas a few years ago and I've been really satisfied with them.
Awesome video. Picked one of these up 2nd hand. Saw runs perfectly when cold, but after cutting for 10-15 minutes...shuts down like there's a dead battery...yet battery has plenty of life. Sounds like cleaning the armature and brushes is going to potentially resolve this issue??? I think I just found my project for this Saturday afternoon. Thank you so much for taking the time to explain the process and why this tool may shut down from any voltage issues.
Thanks man, helpful and to the point; really appreciate that.
Big fan on what you do on your channel, we'd be good neighbors.
And that was/is a plumbers saw, mine has the same tell..
Thanks for your wonderful video :) I'm going to maintain my DeWalt sawzall as well. And now I now how to do it properly :) Thumbs up :)
Just FYI: The long grey steel parts of the armature are called a tooth of the armature stack. The groves are normal, that’s where they ground away metal to balance the armature. The smaller copper bars towards the back of the armature are called commutator bars, that is where the brushes actually ride to deliver power to the armature. Good tear down video!
Great video! Just went through my tool and cleaned everything and seems to work good. Thanks for posting this
Great to hear! Thanks for watching!
Hope your boss compensated you for your time. 😊. Good video!
He did! Plus I was glad for the content. 🙂 Helped me extend help to others! Glad you liked it! And thanks for your comment!
Found a discarded unit (Dewalt DCS391). Luckily I had a battery, seemed to work OK when first turning on, but decided to follow the breakdown video and found that the blade holder was rubbing on the inside top of the aluminum casing to the point that it ware a grove through it. Wondering how hard it would be to gut the top and reinsert gears, etc. into a new casing, or if I need to replace the whole top end. Not sure why the contact happened in the first place unless the previous owner used too much pressure?
I'm glad you touch upon grease in this video, because few people seem to want to mention lubrication at all.
I figured general bearing grease would work fine, but do you recommend any kind of regular intervals? I'm assuming the factory lubrication is sufficient for a while but most things eventually need more.
Thank you for your comment!
It depends on your use of the tool, if you do a lot of drywall cuts I would say to check every few months, or if your constantly cutting steel and getting the unit too hot to touch then same, but if your just using ng the tool every now and again then every other year or so shouldn't be a problem
@@DoubleBitsWorkshop Fantastic, thank you
Hello thank you. What type of Greece should be used on the reciprocating saw?
I would use some marine grease. From a grease gun. It's not too thick so your gearing will move freely, and marine so it helps with possible moisture. No matter what climate you live in it helps!
Love the video but you must work on rifles or firearms quite a bit with how you phrase stuff lol made the video kinda funny and fun to watch, I might have to clean out my trigger group on my rifl…I mean sawzall also.
18:06 what is the brand name & part number of grease that you used?
I want to know the substitute for dewalt grease that is readily available in store. Thanks.
I used some red and tacky #2 or marine grease, from what I can find it seems to be the closest thing to what DeWalt suggests using. Marine grease should help to maintain use even if slight moister has gotten into the saw. From my past experiences, having any help to keep tools working and rust free in all weather can only help as well!
@@DoubleBitsWorkshop thanks
