Hi. I'm in a semi-isolated situation and don't know who to ask about this, locally.

I just opened up my Bosch angle grinder the other day to check the brushes. While doing that, I noticed there was grease around the bearing on the power shaft, but no grease (and no trace of any) on the gears that send the torque through the 90-degree bend. Should I grease these gears?

Thanks.
