How do you access your HM in Pokemon Red? - Answers

You have to teach HM to Pokemon. After you do that, you need to get the badge that allows you to use the HM outside of battle. If you've already done those 2 things, then you need to press "start," arrow down to "Pokemon," select it, select the Pokemon that has the move, then you will see a couple options. You need to click on the HM move. Then the Pokemon will use it. One more thing. If you need to use the HM for "cut," (teach this to grass Pokemon) then you have to be touching and facing the tree that you need to cut. For "surf," (water Pokemon) you have to be facing and touching water. "Fly:" (flying Pokemon) you can't be in a building or cave. "Dig:" (rock/ground Pokemon, this is a TM move, but still can be used outside of battle) you must be in a cave or building.
