TM 10-3930-671-24 APPENDIX E LUBRICATION ORDER E-1. GENERAL LUBRICATION INSTRUCTIONS. This section contains lubrication instructions necessary to keep the truck in operating condition.  Figures E-1 through E-3 illustrate the truck and locations of lubrication points.  The following paragraphs describe the lubrication figures and how they are used. Do  not  start  engine  or  move  truck  when  anyone  is  under  truck.    Severe  injury  or  death  could result. a. Intervals.  Intervals (on-condition or hard-time) and the related man-hour times are based on normal operation. The  man-hour  time  specified  is  the  time  needed  to  do  all  the  services  prescribed  for  a  particular  interval.    On-condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program (AOAP) laboratory.  Change the  hard-time  interval  if  lubricants  are  contaminated  or  if  operating  the  equipment  under  adverse  operating  conditions, including  longer-than-usual  operating  hours.    The  calendar  interval  may  be  extended  during  periods  of  low  activity.    If extended,  adequate  preservation  precautions  must  be  taken.    Hard-time  intervals  will  be  applied  in  the  event  AOAP laboratory support is not available.  Hard-time intervals must be applied during the warranty period.  Intervals shown in this lubrication section are based on calendar and hourly times or calendar times and mileage.  An example of a calendar and hourly  lubrication  is:    M/60  H,  in  which  M  stands  for  monthly  and  60  H  stands  for  60  hours  of  truck  operation.    The lubrication is to be performed at whichever interval occurs first for the truck.  Special lubrication intervals and services are shown by the use of an asterisk (*) symbol. b. Determination of Operating Hours.  The reading on the hour meter is the basis of all lubrication intervals. • Drycleaning solvent (P-D-680) is TOXIC and flammable.  Wear protective goggles and gloves; use only  in  a  well-ventilated  area;  avoid  contact  with  skin,  eyes,  and  clothes;  and  do  not  breathe vapors.  Keep away from heat or flame.  Never smoke when using solvent; the flash point for Type I drycleaning solvent is 100°F (380C) and for type II is 140°F (600C).  Failure to do so may result in injury or death to personnel. • If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical help.    If  solvent  contacts  skin  or  clothes,  flush  with  cold  water.    If  solvent  contacts  eyes, immediately flush eyes with water and get immediate medical attention. c. Clean Fitting Before Lubricating.  Clean parts with cleaning solvent.  Dry before lubricating. d. Lubrication   After   Fording.      If   fording   occurs,   lubricate   all   fittings   below   fording   depth.      Fording   is   not recommended for the truck. e. Lubrication After High-Pressure Washing.  After washing, lubricate all grease fittings and oil can points outside and underneath truck. f. Level  of  Maintenance.    The  lowest  level  of  maintenance  authorized  to  lubricate  a  point  is  indicated  by  either Operator/Crew (C) or unit maintenance (O).  Operator can lubricate points authorized for unit E-1
