WARNING
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. Do not smoke.
Area should be well ventilated.
WARNING
·
Death or personal injury may result from the explosion of fuel fumes exposed
to an open flame or spark, or to static discharge. Do not permit smoking, any
open flame, or spark producing equipment within fifty (50) feet of the liquid fuel
filter-separator. Ensure all equipment is well grounded prior to commencing
any operation or maintenance task.
·
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.
NOTE
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.
a. Removal. (Figure 4-13)
(1)
Connect the liquid fuel filter-separator grounding cable (1) to a secure ground.
(2)
Tip liquid fuel filter-separator (2) up on end.
(3)
Depress and latch open the manual vent valve (3) to relieve any pressure from filter vessel (4).
(4)
Place container close beneath sight gauge (5). When sight gauge (5) is separated from filter vessel (4), the small
float ball (6) may drop out. Use the container to capture the float ball (6) and prevent loss.
(5)
Remove the two mounting screws (7) lock washers (8) and flat washers (9) that secure the sight gauge (5) to the
filter vessel (4). Slowly remove the sight gauge body (5), capturing the float ball (6) in the container.
