TM 9-2350-277-20-1 HOW TO USE THIS MANUAL (cont) NOTES Contain important facts to make the procedure easier. Helper Helpers are needed in procedures that require more than one person. A helper may be needed to help lift objects or act as an outside observer. If a helper is needed to perform a procedure, the INITIAL SETUP will list “Helper (H)” under the PERSONNEL REQUIRED heading. If a helper assists with a step or substep, the step or substep will include: “Have helper assist”. If a helper performs the action alone, the step will start with “(H):”. Locational Terms The terms “front”, “rear”, “left”, and “right” are used to indicate where items are located on the vehicle. The point of reference for these terms is different for Carrier items and Power Unit items. (Carrier items are items which are not on the power unit. Power unit items are items on the engine or transmission.) If you are working with carrier items, use this point of reference. Think of the location as if you were sitting in the driver’s seat looking out the hatch. LEFT REAR RIGHT FRONT xxxvii Change 2
