Started smoking from trigger
Maybe there is a interference suppression capacitor for radio supression near the switch have to only remove it . i do it by the most Bosch powertools because it made more problems than the purpose for which they are.
The ultra short wave radio listeners are not much more today everywhere its DAB+ do not suffer
My hitachi jackhammer runs slow and gets hot
The armature AND electric field must together replaced to get a safe working again, and the defect will not repeat if it be shure have its operating hours on it and give a full service.
My kango 637 breaker runs but no power is getting to the chisel canyou help please
There are a couple of main things that could cause this. Unfortunately this is an obsolete machine and I doubt you will be able to find any spares for it. Probable causes are worn seals/in need of service. Worn armature pinion gear and/or crank pinion gear. Ideally you should replace both if either one is damaged, even if the other one looks ok. There are always other possibilities but they it would need stripping on the hammer mech to check all the piston/pins/anvils etc. This is a very old machine (I cut my teeth on these when i started in the trade 20yrs ago).

Kango 900 hammer:\r\nDon't know how to greace the
Milwaukee K900K or the English Kango 900K Blue old or Red some younger handle it differs very much English Kango was using a thick brown grease in 2 chrome colored plastic bags . the Milwaukee K900K has a lubrication grease also not oil but be aware of the operating hours i f you have a K900K model from Brand Milwaukee tools replace also a service kit and the bearings on the armature is important also Its neccesary to protect you from damage
if you have a English Kango its hard and expensive to get a spare parts and most times the tools are worn in the front of the chisel stroke bolds do not get right close and the piston pins are worn it was a good tool about 20 years ago i have serviced much of them . but the first thing thats important that its air-tight in front of the chisel and everywhere thats having a mechanic/pneumatic duty
Milwaukee Services and fill k900k with (IMPORTANT) the right number

Baumer ag jack hammer
This is what kind of tools you are missing for to do it without damage some parts by some brands a bearing press .. to press out the gears out of the bearings but beware in some cases there can be uses a forelock and the bearing of the gear can sitting behind a locking ring. allways use the right service manual before decide to. and use safety glasses if using a bearing press

I have a te 500 it not knocking at full strength
A Broken front ring which blocks the lock bolt ?
Is there enough lubrication flow if something is broken inside replace ALLWAYS a complete servicekit , because its , beware of the Turmopol oil is expensive. there are equivalent oils if you asked special for it also by Hilti to buy.
Hilti and Duss are not the 2 cheapest brands of powertools.
Special Tolerance-free bearings are used it is all super calculated on a number of operating hours and about if something is defective, a complete overhaul is necessary.
These hammers may leak no trace of oil in the front until 2006 HILTI has in my Country support , but after this date
exclusively support to the end-users and support closed for brokering.
H45sb hitachi moter run but hammer and stop how can i fix it
If pos 22 980-707 is broken it does not function , also if pos 35 is broken 932-815 then also the motor drives but no hammer , also if pos 8 is not moving 987-705 because the lubrication is not good anymore if started leaking and if that happens the piece and all your o-rings will be worn by heating up because thefront ofyour hammer must be air tight all the way , a demolition hammer is made for lasting long hours but leaking although it is still so small its in a few hours inside becomes to hot for the seals o rings and lubrication and then there are Discussions for to get a Service Kit (H 45Sb) - ( 987-712 ) the hammer is to old for economic repair by others some parts are not anymore available, i know it where good hammers , but marketing technical changes in weight, more
more speed and less vibrations and for 7 years max parts in stock (not sometimes 15 years as before) and over that time its all discontinued demolition hammers are averaged of use of 6 years by normal usage.
Lubrication is not the problem but in front its must airtight otherwise
is bad for your arms and shoulders because its build for timing when its airtight.

Brand new and not jacking
if you push the chisel of the hammer on an object the battle piece must become free in the cilinder and must work or something is blocked or wrong intern as it will not work , or the wrong chisel was selled for your machine . remove the chisel and put a long big screwdriver and push it in the locking sleeve as far as possible there must something moved from 2 or about 4 cm depends on the volume of the machine but if nothing moves then go back to your dealerfor warranty.
