General Safety Requirements:
Liquid fuel filter-separator removed from
AAFARS. (TM 10-4930-250-13&P, Para. 2.8.)
Fuels are toxic and flammable. Do not get on person
or clothing. Do not use near open flame. Area
should be well ventilated.
Using dry cleaning solvents incorrectly can cause
injury or even death.
Fuel is flammable. Do not smoke.
a. Removal. (Figure 4-1)
Rubber gloves should be worn when handling fueling system components due
to the toxic effects of some fuel additives.
Serious eye and skin injury could occur from venting of fuel when manual vent
valve is opened. Wear suitable protective clothing and eye protection.
This procedure assumes that the liquid fuel filter-separator has been defueled.
However, some fuel will have accumulated in the sump due to normal drainage of
saturated coalescer elements after defueling.
Connect liquid fuel filter-separator grounding cable (1) to a ground rod.
