求翻译：室温条件下：小车走轮安装后第一次加脂应加够（空间充满度75%），润滑脂不易挥发，通常每半年加脂约6-8克，且在，具体可通过平时的检查来决定是否需要加脂。是什么意思？

Room temperature: the first car to go round installation fatliquoring should be added enough (space full of 75%), grease less volatile, about 6-8 grams of fat usually every six months, and, specifically through the usual check to determine the need for fat.
