Makita A-90582 or (the equivalent)


Hitachi 981840 Hammer Grease

But dont forget to replace all o-rings and seals at the same time some older models have special wear tear parts sets for service also called maintenance spare parts. If the brushes are short then its time for service.

Dont forget to lubricate o-rings when mounting parts in. For flat x rings you can hold then in hot water to make them softer and thrn put ring in a place

181490-7 grease 30g 1 pcs complete be shure there are no cured o-rings or bad gaskets .

188015-8 its the maintenance kit for the service it contains already this 30 grams grease, where come 60 grams advise ? i like also to use some more grease by this heavy kind of hammers. But tools like Hilti with liquid (oil) lubrication and very tight tolerance ball bearings if there is to much (turmopol) oil used it will be damaged, and too little oil also its calculated. I cannot give garantee that 60 grams are advised by a makita service, if you order a maintenace kit ask the seller about why it only contains 30grams. The information to use 60 grams ? doubt.

254031-3 pos14 part inlay key can be damaged pos 11 drive rod 315146-2 can broken IF mechanical damage or dried out by leaking gasket / orings.
For better repair use after a repair of some parts an maintenance kit 193394-1 If the working hours are on it, but also after an repair on other parts because leaking tools can be dried out and give cured o rings in a very short time by building up overheat temperature inside and will not build up pneumatic power it will not do the job and is not good for physical strain.

Order an maintenance kit for it , when the working hours are on the tool , all given parts in the kit must be replaced its not a good idea to only grease it, the tool should not leaking by the chisel. then there will be a bad break-force and give a long working job..

demolition hammers require hydraulic oil in most cases.
Any good tool shop should have hydraulic oil to suit.

Makita have most cases a problem with the stroke bolt in front of the locking sleeve a broken ring that will blocked the stroke bolt.
In some cases the locking sleeve is also damaged , a rotary hammer is not made for demolition only a little small task but not for a long load , the metal pieces of the machine is no hard enough for long lasting .

first ordernumber 931848 lubrication necessary it has its working hours on it.
parts to change in priority
1 x 944-927 , 949457Z , 956-960 , 944-936 , 956-965 ,
999032 , 956-996 , 944-928
the important thing is that the machine is airtight at the front so as not to burn the O-rings through the air and incoming dirt friction look the orings good and if the lock bolt on the front feel not smooth replace that also and every oil seal you can find its different what should neccesary but that the tool runs with thick and dirt beaten oil . solvent clean the hard metal parts and replace if there are grooves on or cracks
