Oddly enough, that's pretty much how he was portrayed in both the G1 comic AND cartoon, as well. They guy who patched people up, carried out the robotic version of first aid. And also conspired with Grapple, his partner in crime, to build things. In the cartoon then, he was there to replace Ratchet, be the Autobot's medic. Due to that, he was always around. He even got his own episode, Hoist Goes Hollywood (written by the late Earl Kress) where he gets talent spotted by a Hollywood director and gets to star in a movie along with a few other Autobots. It's a fun episode, and goes to show just how much Earl liked to bash up the Transformers !
In the comics, the story just repeats, really. He was always around, always there, patching up the Autobots. His big moment came pretty early on, when he helped save a bunch of concertgoers by shoring up the stage that Brick Springstern and his band were performing on, and telling the guys to keep playing, lest the crowd start to panic. Sadly, Hoist came to a rather sticky end in the comics, when he was killed by the Underbase-infused Starscream. In IDW, he's mainly been a bit part player, but he's currently on the Lost Light, so who knows? Big days could always be ahead for ol' Hoist.
Hoist is one of my favourite toys from this era of Transformers. Nice to play with, good, bright colours, and fun. The character is sound, and has been represented pretty well in fiction; that's not to say I wouldn't want to see more of him in IDW, and a Generations toy of him out asap though.
