Here's an article posted on the ROBLOX Wiki that might suite your needs. It contains some great information.

Try this out all u need to do is edit the variable Id

local tool = script.Parent

tool.Activated:connect(function()
local id = "animationid"
	local humanoid = tool.Parent:FindFirstChild('Humanoid')
	local ani = Instance.new("Animation")
	ani.AnimationId = id
	
	if humanoid then
		local Lp = humanoid:LoadAnimation(fd)
			if Lp then
				Lp:Play()
			end
			end	
end)
