Servicing a demolition hammer

[aidan]

I have been donated an old hitachi demolition hammer.

I will change the brushes, and take the whole demolition mechanism apart and clean and put in new grease.

there are also o ring in the demolition barrel to be changed as it’s them make the seal. Was wondering what type grease should I use, its a different grease to regular grease I think.

was also wondering about the o rings are they made from a harder compound thanregular black rubber.

Mine has to be re-gassed too I think, professional job.

Have you an instruction book or can look it up online?

I think it has to be high melting point (HMP) grease for the Kangos which is a lot thicker than the normal LMP worksho[ grease
