Pressers were coming in and going out [of the olive-press], and there were tamei beverages in the olive-press; if between the beverages and the olives there is enough [distance] for them to dry their feet on the ground, [the olives] are tahor.  [If] in front of the pressers and the grape-harvesters there was tumah, they are believed to say, “We did not touch [it].” And similarly the children among them may go outside the entrance of the olive-press and relieve themselves behind the fence, and they are [deemed to still be] tahor. How far may they go and remain tahor? [Only] as far as he can [still] see them.

[With regard to] olive-pressers and grape-harvesters, once he brings them into the area of the cave, it is sufficient; [these are] the words of R’ Meir. R’ Yose says: He must stand over them until they immerse. R’ Shimon says: If they are tahor to themselves, he must stand over them until they immerse; if they are tamei to themselves, he does not have to stand over them until they immerse.

One who places [grapes taken] from the bas-kets and from the expanse on the ground [on to the wine-press], Beis Shammai say: He must put [them in the wine-press] with hands that are tahor; and if he puts [them in the wine-press] with hands that are tamei, he has rendered [the grapes] tamei. Beis Hillel say: He may put [the grapes in the wine-press] with hands that are tamei, and [can still] separate their terumah in taharah. [If one took grapes] from a bucket or from an expanse on leaves, everyone agrees that he must put [them in the wine-press] with hands that are tahor, and if he put [them in the wine-press] with hands that are tamei, he has rendered [the grapes] tamei.

One who eats [grapes taken] from baskets and from an expanse on the ground, even if [the grapes] are cracked and [their juice is] drip-ping onto the wine-press, the wine-press is tahor. [If the grapes are] from a bucket or from an expanse of leaves and a single grape fell [onto the wine-press], if [the grape] has a seal, [the wine-press is] tahor; if it does not have a seal, [the wine-press is] tamei.  [If a cluster of] grapes fell from him and he pressed them on an empty place [on the wine-press, if the cluster consists of] precisely the volume of an egg, [the wine-press is] tahor; [if the cluster consists of] more than the volume of an egg, [the wine-press is] tamei, for as soon as the first drop [of juice] came out, it was rendered tamei by the volume of an egg.
