Instruction for use

	1.Drilling Clear the damaged thread with a standard drill. To repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap.
	2.Tapping Use the special BaerCoil taps for cutting the holding thread into the hole. It is recommended to use a suitable cutting oil.
	3.Install the insert Place insert on the installation tool ans position the adjustable ring so that the insert tang is centred in the tang slot. Wind the insert with a light downward pressure until a half turn below the surface. Don't worl against thread direction as the tang could break.
	4.Tang removal Lift the tool from tang, turn tool 90° and tap down sharply. Use tang break-off tool where supplied. For bigger sizes and spark plug use a long nose pliers to remove the tang.
