How do I make it so that my localscript tool only works when equipped?

I have a tool to make you levitate upwards in a localscript in a filtering not enabled game, but you don't need to equip the tool to levitate when you click. How do I make it so that you do?

This is the script.

local Character = game.Players.LocalPlayer.character
local TorPos = Character.HumanoidRootPart.Position
local Player = game.Players.LocalPlayer
local HumRoot = Character.HumanoidRootPart
local Mouse = Player:GetMouse()
local MystSkill = script.Parent.Mysticism.Value
local LevHeight = Vector3.new(0,.5*MystSkill,0)

script.Parent.Equipped:connect()


local Levitating = false

function levitate()
    if Levitating == false then 
        Levitating = true

        local BodyPos = Instance.new("BodyPosition")
        BodyPos.Parent = Character.HumanoidRootPart

        while Levitating == true do

                BodyPos.Position = HumRoot.Position + LevHeight
                wait(.000001)

            end
            BodyPos:Destroy()
        end

    end


function SetLevFalse()
    Levitating = false
end

function PrintPos()
    print(HumRoot.Position)
    print("MystSkill", .5%MystSkill)
end


Mouse.Button1Down:connect(levitate)
Mouse.Button1Up:connect(SetLevFalse)
Mouse.Button2Down:connect(PrintPos)
