Continuity mistake: When the group of teenagers pick up the hitch-hiker, he goes crazy and cuts Franklin's arm, so they throw him out. As they throw him out the van-door windows are shut. In the following inside shots they're open. (00:16:30)
Continuity mistake: After the hitch-hiker smears blood from his hand all over the side of the teenagers van, in the very next shot as we see the van riding away down the road, the blood has disappeared from the side. (00:16:40)
Continuity mistake: When the group of teenagers pull up at the gas station, watch the door of the gas station closely; a red 'open' sign appears on the door after they pull up, and then vanishes and appears once again. (00:18:20)
Continuity mistake: As the teenagers pull up into the gas station, look at the position of the gas pumps hose and its shadow. In the next shot the gas pumps shadow has vanished and the gas pumps hose is positioned differently. (00:18:20)

Continuity mistake: When Leatherface picks up Pam and puts her on the hook you can assume that the hook has gone through her back right shoulder blade.

(00:46:00)

Continuity mistake: When the dad comes home, Leatherface is wearing a man's face. Then, only a few seconds later when he walks out of the kitchen he is wearing a woman's face, with makeup on it. This occurred due to a scene cut out of the movie. It shows Leatherface taking off the man's face and putting on a woman's face and applying makeup to it. (01:06:35)
Continuity mistake: When Sally escapes from the Leatherface family in the dining room, she runs and jumps through a window, and as she lands shards of glass land all about her. In the next shot as she gets up they're gone. (01:15:20)
Continuity mistake: At the end of the film Leatherface takes a socket wrench to the face and falls down into a roadside ditch getting his clothes rather dirty in the process. Moments later, when he's doing his macabre chainsaw dance, his clothes are all nice and clean again.
Answer: The name "Leatherface" is used in the scene set in the hotel, and the waterfall scene. The grandmother says "leatherface" right after she says "Maryana, crank up the chain saw" in the waterfall scene. She actually says it in a whispering tone, so you have to turn the volume up to the max.
I think you're referring to either a remake or sequel. In this film (the original made in 1974), there is no living grandmother that speaks, scene set at a hotel, character named Maryana, or a waterfall scene.
