Was using my Bosch brute 70lbs jackhammer and it quit working. It only makes a humming sound when I press trigger.

Beware Time for service something does blocking the armature if that happens a bearing or other broken part.

Jackhammer wont hammer

A complete service kit is neccesary its pointless only to change oil, including hardened o-rings and gaskets and oil seals etc. have had their working hours. it all rests on a marketing technical calculation where no user is slicing.
look for your model and a spare parts servicekit and if the neccesary tools are present you can do it on your own. the front second hammer (stroke bolt) must be air-tight the heavy battle piece must be pulled up by vacuum by the stroke cylinder and worn rings on it and everywhere and bad seals will not succeed

Dewalt jackhammer d25980 starting module damaged after only 1 month operation

Dewalt jackhammer d25980 starting module damaged after only 1 month operation; since it is still covered by the what "dewalt calls 3 years warranty" (actually a big fiasco), it was sent to the dewalt authorized technicians; it took them 21 days to theoretically solve the problem. they stated that the module was defective, and that after having replaced it the machine was ready to operate. but the truth is that only after a 30min operation it again stopped working, now they are stating that the machine is not fit to operate at altitudes exciding the 3000 ft.
so my question are:
1st if that's the case; why do they sell a product that will not operate in the city it was purchased which already exceeds the altitude limitation they came up with,(of which nothing is mentioned on the operation manual)
2nd why did the machine operate very well for the first 60 hrs; if the altitude would be a functional limitation, the jackhammer should have malfunction right from the beginning.
to me the true fact is, Dewalt does not want to assume their responsibility, their product is terrible and they don't want to honor their warranty. if altitude is a problem they should reimburse the money immediately and second if that's not the case, they should totally substitute the defective apparatus, which is not even 3 month old.

Plug in the hammer and no response when you push the trigger

To trouble shoot, easiest to hardest:
1. Check both brushes, they should be 1/4" long or more and evenly worn, the spring should push carbon firmly against armature. If there is a small pin pushing out of the center of the brush it is worn too far and needs to be replaced. The pin is designed to push excessively worn brushes off the armature so as not to damage it. >
2. Check for power at cord going into the switch with a multimeter, if 0V replace the cord, if 110V; push trigger and check for power coming out of the switch, if 0V replace the switch, if 110V >
3. If these are all OK you need to check the armature on a growler to see if it's OK.

My A5 just rapid fires when the trigger is pulled even in semi, if you release the trigger it stops but does it everytime I pull the trigger and the E-trigger seems to be working fine

Make sure your battery is new. It doesn't take a lot of voltage drop to affect performance.

Make sure your marker is clean, and properly lubed with a quality oil make for paintball.

Make sure your board connections are secure. You can change modes on the e-trigger yes? Go through them and fire a few times in each to ensure it's changing.

Make sure you have a full tank of air while your testing to make sure this isn't a problem as well, or causing your issues.

Good luck!

Dewalt angled finish nailer, just got, when nose is depressed and trigger pulled, just sound of air releasing, wont fire..... need trigger assembly?

if air is released when the trigger is pulled then stops when the trigger is released , then the trigger is doing its job. its probably a firing valve issue. four screws will take off the top cap of the gun the firing valve is inside of the cap . first check to see if the gun has enough oil( unless its an oil less gun) if its dry then grease or oil all of the orings, if this dose not work check to see if any of the orings or plastic parts need replacing. pls rate this answer...;tks
