I have a question about, Hobby Lobby's, Planetary Gearbox 3.33: 1 for Speed 400. HLIMJ8050.

According to the enclosed instructions I have to lubricate the gears every 1 to 2 hours of running of the electric motor. It is a very unusually short period between lubrication. Could any one clarify this requirement?

The instructions recommend PTFE type grease for the gear teeth and Kluber Isoflex Topas NB 52 grease for the gear pins. Where can I get the recommended greases in small quantities?

Is there a single type of grease that can fulfil both requirements?

Your assistance would be highly appreciated. I cannot use this gearbox till I get the recommended greases in my hand.
