DeWALT D25940 Type 2 Hex Demolition Hammer service

I broke a connecting rod on my demo hammer and got the replacement with a new piston and have no idea what kind or how much lube to assemble it with. The oil inside feels like 90w gear lube but I have no clue.
Any ideas?
TIA,
Vince

I have no idea. I have a similar demolition hammer, but SDS max; it's pretty beat up, but works good.

This is what I found: https://www.ereplacementparts.com/grease-p-68586.html?osCsid=j4kcfqh894po6frde5jrtep603

Yeah three different kinds of grease. I picked out some redline, it seems thin enough.
Thanks!
