j. At removal of hydraulic hose assemblies,
pneumatic hose assemblies and tube assemblies, install
plastic or polyethylene caps and plugs in the open lines
and in the component ports. This action will minimize
spillage and inhibit corrosion, and will prevent the
introduction of contaminants in system components.
k. Do not lubricate electrical instrumentation at
any time. These instruments are lubricated and
encapsulated at manufacture and do not require
I. Use extreme caution when fuel and oil lines
and fittings are disconnected. Observe all base safety
and fire regulations concerning volatile and toxic liquids.
m. When cleaning metallic parts in dry-cleaning
solvent, accomplish these procedures in a well-
ventilated area. Keep fumes away from open fires and
flame. Avoid breathing toxic fumes and wear protective
prescribed by base fire and safety regulations. Obtain a
C02 fire extinguisher prior to using dry-cleaning solvents
and during disconnection and connection of fuel lines.
n. When installing replacement thermocouple
wire in a sub-module or junction box, check the
appropriate schematic to ensure that the replacement
wire corresponds to the type of wire removed. Match
the length and gauge of the replacement wire with the
length and gauge of the removed wire to retain the
correct thermoelectric characteristics.
Observe all base fire and safety
regulations when handling flammable
and toxic liquids. Failure to observe
this warning may result in serious or
fatal injury. Exposure to turbine oil
will cause skin irritation.
o. When maintaining turbine lubricating oil and
MIL-H-83282A hydraulic fluid lines, use extreme caution
to avoid contact of oil with the skin and clothing.
Remove saturated clothing immediately and thoroughly
wash all areas of skin exposed to oil to avoid painful
skin rash. Perform maintenance actions in a well-
ventilated area. Remove spillage of oil on painted
surfaces immediately, using Specification P-D-680,
solvent. If oil is not removed from painted surfaces,
damage to the paint will result.
Section II. SERVICING INSTRUCTIONS
Service the auxiliary systems and components
upon receipt-of the equipment, and as required to
replenish liquids. Service the tires in accordance with
the procedures outlined in the following text.
Inflate the tires of the test trailer assembly (figure
1-2), the engine test dolly assembly (figure 128), and the
auxiliary trailer assembly (figure 131) in accordance with
the tire pressures specified in tables 1-3 and 1-4, as
6-5. Crane Assembly.
Service the hydraulic actuator on the crane
assembly (figure 1-5) upon receipt of the equipment,
and as usage dictates, in accordance with the following:
a. Remove the filler plug from the cylinder of the
b. Fill the cylinder of the actuator, using the
hydraulic fluid specified in table 1-3.
c. Install the filler plug.
d. Check the action of the actuator in both the
speed and power modes, operating the piston of the unit
in both directions. With no movement of the pump
handle, check to ensure that there is no movement of
the boom assembly caused by creep or bypass of
hydraulic fluid in the cylinder of the hydraulic actuator.
6-6. Hydraulic Start System.
Service the hydraulic start system in accordance
with the following:
pertaining to handling toxic liquids.
Specification MIL-H-83282A fluid will
cause skin irritation and other adverse
