CAUTION Use only the type lubricants specified on current lubrication order and do not overlubricate.  Over- lubrication may cause equipment failure or damage to working parts. a. Refer to LO 10-3930-669-12. b. Keep all lubricants in closed containers and store in a clean, dry area away from excessive heat.  Do not allow dust, dirt, or other foreign matter to mix with the lubricants.  Keep the lubrication equipment clean and ready for use. Before  lubricating  the  equipment,  wipe  all  lubrication  points  to  remove  dirt  and  grease.    After  lubricating,  clean  all lubrication points of any spilled or excessively applied lubricant to prevent accumulation of dirt and foreign matter.  Keep all external surfaces and parts not requiring lubrication free of lubricants.  Inspect all oil lines, fittings, and filters for leaks immediately after lubrication and during operation. 3-1
