20 Most Recent Dewalt D25330K 2KG Sds Plus Demolition Hammer 240V Questions & Answers

A real Hilti brand means it has got the operating hours on it. Only service a complete kit of components , this machines are have most liquid oil lubrication (most of the times a very expensive) Turmopol oil and special poor tolerance bearings HILTI and DUSS are high quality machines , Duss machines i prefer some higher then Hilti because of the long last service for more then 40 years old machines they have all te parts for them , but not cheap Unfortunately. If a hammer stopped working like Dewalt all the parts are simple to get. most of the times a broken powercable or a brush that have become in protected state autostop , Dewalt hammer in the States is not the QS quality of Europe i know . but quality like the old ELU machines instead of black and Decker , Nice machines and are not fast leak , but it could also after a long period.

Hi
It could need more grease around the piston or it could be the teeth on the gears are stripped

The gears inside that engage the chisel points to move back and forth are either not alligned properly or are stripped. You'll have to open up the hammer to see what, exactly, is the problem.

Hilti has sensors in their tools to detect when things are wrong with them that will shut the tool down under certain conditions. The most common is when the brushes wear down to a point where the tool is shut down so you don't do damage to the expensive armature. Hilti is very stingy with the information on how to reset the system even if you install new brushes, they want you to send the tool to them for repairs or reconditioning. They do a great job, very quickly and you'll essentially have a new tool but it can be expensive so if you want to go this route call to see what the service will cost or if they'll tell you what's wrong, sell you the parts needed and tell you how to reset the sensors.

they went out of business a few years ago,i have some parts no manual i need one also

i have 900 kango jack hammer motor work but don't jack in sacramento any repair dose work on the jack hammer can you give info who work in sac thanks jim

The shaft from the motor to the drive gear is likely not working the action of the hammer. There is a gear which spins the gears to achieve the hammer action, suspect the gear is either stripped, broken or both.

If you don't get it working I will buy it not working and stripped. let me know ( kango 426)

No wrong There are special maintenance kits for these tools , bewere on the active parts if there is service needed if there is already a problem maybe its too late . 581016 01 Service Kit

me id use google earth to locate there service center (where it got sent to repair )and then see there (elevation) if it exceeds 3k feet (I suspect it might) then id gather this info and send it in a nice letter to your states attorney general for fraudulent claims , im betting one letter of intent to pursue consumer ***** from them to dewalt and you'll see a differnet outcome !!

Breaker chisel fat of any brand is alowed thats important for the guiding fields in the locking sleeve and also a little longer lasting of the stroke bolt. Its a good thing but in practice 70% of the proffesional workers does nothing used on the chisel. BUT ... Small independent workers usually.

The first ring is pos 88 remove but wait ,! first solvent clean the whole head and the fitting part of the chisel try first before take any operation on the chisel to shift the rubber gasket on the bit with a little screwdriver if its cleanwet before all and then remove pos 88 a locking ring then look good on the parts order of your right powertool diagram setting of your hammer. If its cleaned and the parts are removed from the locking sleeve wher the chisel is in place the chisel with whole hammer in a vise and only then if the 2 locking devices out the locking sleeve are removed take a bench hammer with the point on the front part pos 94 between chisel and hammer sleeve and with a heavy mallet on the bench Hammer the machine from the chisel.

Return o the store

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.

enter model in "find it now", click on the spyglass
click on type,
left side navigation should give option for both parts breakdowns and instruction manuals

Maybe a thermal problem in the electronic modul and also control the powercable on a leight tensile load.

kango 950 was the hammer drill version. Usually when they stopped hammering they were due for a rebuild. These units have a aluminum piston that rides in a steel tube striker. When the 2 rubber piston rings wear out you will get the described problem. The Kango's use a special tan grease so you cannot just yank it apart and replace the 2 rings with o-rings and grease. I had to rebuild 15 900 and 950's because the previous mechanic used the wrong grease. https://project21designs.com/kango-950-parts The link sells grease & rings.

This is an indication that the hammer needs service. When you take the barrel off you will see the striker. There is a piston inside the striker, when the rubber rings on the piston wear out you have the problem you describe. time to replace the motor brushes clean and regressed, make sure to use the correct grease, Check the backlash on ring and pinions. Don't put too much grease on the piston or it will stick and not strike. Good luck I forgot to ask which version. This is for the uk atlas coco, silver with blue or red handle
