cleaning compound make a drier foam. Dry foams give
greater dwell time and prolong cleaning action, but wet
foams clean better.
k. Allow foam to remain for up to one minute, but not
long enough to dry, then scrub and rinse.
CAUTION
Insure that tank is drained to prevent a build-up
of highly concentrated solution, which may
damage aircraft surfaces.
l. When cleaning task is completed, drain detergent
solution from tank and flush with fresh water.
2-8.3. UNIVERSAL WASH UNIT.
WARNING
Use the universal wash unit in the horizontal
position only.
a. Connect the strainer unit to the intake hose.
b. Connect the wand and nozzle spray to the output
(discharge) hose or connect the discharge quick
disconnect to the aircraft wash manifold quick
disconnect.
c. Insert the strainer unit into a container of water or
cleaning solution.
d. Press and hold the start or remote start switch;
observe the pressure gage. It should immediately
indicate an increase in pressure.
e. After the pressure reaches approximately 10 psig,
release the start switch. The unit should continue to
operate.
f. The unit will deliver approximately 2.5 gallons per
minute at 30 psig.
g. Press the stop or remote switch to stop the unit
from operating.
2-8.4. CABINET-STYLE
AQUEOUS
PARTS
WASHER.
WARNING
The materials used and waste generated from
this cleaning process may be hazardous to
operating personnel and the environment. Drain
any entrapped solution back into the washer.
Contact the local industrial hygienist,
bioenvironmental engineer, or Environmental
Office for guidance regarding personal
protective equipment (PPE) and other health
and safety precautions.
Parts will be very hot after the cleaning process.
Handle with thermally protective and water
repellent gloves.
CAUTION
High pressure parts washers shall not be used
for cleaning bearings unless specifically
authorized. Due to the maximum allowable pH
(pH 13.5) that the required cleaning compound,
MIL-PRF-29602, can reach, cognizant
engineering authority approval is required before
cleaning aluminum alloy and IVD aluminum
coated parts.
a. Determine the reservoir capacity of the parts
washer. Fill the reservoir with a solution of
MIL-PRF-29602 cleaning compound, diluted per
manufacturer’s recommended concentration.
NOTE
Do not use the parts washer until the cleaning
solution has stabilized at the required
temperature. Agitation of the solution prior to
reaching elevated temperatures may result in
excessive foaming of the cleaning solution.
b. Allow cleaning solution to stabilize at
manufacturer’s recommended temperature (usually
140
°
F to 180
°
F).
