Lubricants. Some of the lubricants used to maintain fire control equipment are aircraft and instrument
grease, special preservative lubricating oil, and graphite-petrolatum antiseize compound. Grease, compound, and oil
should be used sparingly since the aim of good lubrication is to apply a minimum amount of lubricant consistent with
adequate lubrication. Thoroughly clean and dry all parts before lubrication. The general application of lubricants upon
assembly is as follows:
(1)
Clean all parts to be lubricated using a clean cloth, moist but not dripping, with a cleaning solvent.
Remove all dirt and grease then dry the parts using a second clean, dry cloth.
(2)
Clean rubber parts using a clean cloth, moist but not dripping with mild soap and water.
(3)
Use a clean brush or cloth to apply grease and a hand oiler (fig. 3-35) to apply light weight oil.
Figure 3-35. Hand Oiler
(4)
Never put a dirty brush into clean grease. If brush is dirty, dip into a cleaning solvent and wipe dry with a
clean cloth.
NOTE
In steps (5) through (9), refer to figure 3-36.
