WHat kind of oil is required. Rotella #40 is not immediately available in Austalia. I suspect a standard30/40 oil may be ok. PLs advise.

No, that will burn you seals and o-rings in a short time
15w40 or that kind of Oil will go on like syrup no then you go for a new service kit of seals and rings .
But the important things that are quickly to see .
If its a heavy old large hammer 10 kilo or more with a heavy battle piece then use a hammer fat(grease)only if there is no oil fill glass present. in place, but if it looks that oil has seated and the parts are made for high speed, use at least a zinc-free hydraulic oil Because of the heat dissipation, which is really high because of the internal air compression.
Oil for a high-pressure cleaner which have a one-time oil filling without oil filler cap which oil can also be used.
Turmopol oil brand Hilti always good but is very expensive.

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

Where do I ad oil to a makita hm1500 demolition hammer

Go to, put your model number in search box in the top right. Two models of the HM1500 will come up, select yours and open the owner's manual. Find the paragraph labeled 'Lubrication' and follow it precicely. Demo hammers are very picky about what type of grease they use and how much. Too thick and they won't work, too thin and they won't lubricate properly and the parts inside are very expensive to replace. Same applies to how much to use.

Dewalt demolition hammer stopped hammering. motor runs but no hammer action

could be a few problems, the striker could be stuck from debris or the ram might be hydraulically locked. they make a rebuild kit for this tool if you are mechanically inclined. I would suggest first going to their site and downloading a parts breakdown and there you will find what is involved and the parts listing. It is "" and on the left hand side type in your model number and then follow the links to download this. Let me know if you need more assistance.

Hello - I have a Hitachi Demolition Hammer PH-66A. What type of oil should I use in it? Thanks.

Hitachi sells a pneumatic oil for use in its air power tools. Your local Hitachi dealer, or any pneumatic dealer will sell the oil. The brand is not as important as using a few drops directly into the air fitting when starting a day of work. If used heavily, oil it again mid way through the working day.
