2030N Planer/Jointer motor question

TLDR: How much grease should i put in the gearbox of a 2030N? Hello everyone. I scored a 2030N for cheap. Runs ok but since I'm restoring it I decided to replace the grease in the gear case. After removing all the old waxy grease I discovered there's zero info online about what type of grease or how much should be used. I'm pretty sure I've got the right type of grease but any guidance as to amounts or anything else re: this tool would be greatly appreciated. Thanks fellow teal-ians
