How do you make an animation run on a arm with a tool equipped?

So I have a animation that runs on a player when a tool is equipped. It doesn't affect the right arm when the tool is equipped though.

Heres my tool script, I don't think it affects this problem though.

local Tool = script.Parent
local Animation = nil
local Track = nil
local Player = game.Players.LocalPlayer

function Equipped()
    --set up animation
    local Character = Player.Character
    Animation = Instance.new("Animation",Character.Humanoid)
    Animation.Name = "Axe_Swing"
    Animation.AnimationId = "rbxassetid://1464544078"
    Track = Character.Humanoid:LoadAnimation(Animation)
    wait(2)
    Track:Play()
end
function Unequipped()

end
Tool.Equipped:connect(Equipped)
Tool.Unequipped:connect(Unequipped)
