TM 9-2350-277-34 HOW TO USE THIS MANUAL (cont) If a helper is needed to perform a procedure, the INITIAL SETUP will list “Helper” under the PERSONNEL REQUIRED heading. If helper assists with a step, the step will include: “Have helper assist”. If a helper performs the action alone, the step will start with “HELPER”. The terms “front”, “rear”, “left”, and “right” are used to indicate where items are located. 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. If you are working with power unit items, use this point of reference. Think of the locations as if you were standing at the transmission end of the power unit and facing the flywheel. This rule applies whether the power unit is IN or OUT of the carrier. References within a WP refer to a different manual or to another WP in the same manual. A step in one WP may be a complete WP someplace else. Below is an example of a reference step from the WP: INSTALL ENGINE COOLANT HEATER KIT. Example: Lower power plant grill (see your -20). The tools needed to do the task will be listed in that task. For all WPs, the following comments apply: ix
