If, as your question indicates, you believe in evolution, the egg came first. Aminals living in the sea (fish, invertabrates, etc.) were laying eggs long before land animals, including birds, evloved. Also, reptiles were laying eggs on land long before the avian species came into being.

If the bit turns freely it's possible you have the change ring in the forward position. The HM0860C is a demolition hammer, not a rotary hammer so the bit should not be rotating under power for any reason. On the HM0860C the changing ring on the nose does slide forward to let you choose and lock the chisel bits in 12 different angles. Check to make sure the change ring is in the locked position.

The o-rings are most likely worn out. Take it to a service center and have them diagnose it. It probably needs a service kit installed.

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.

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..

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
