NOTES - CONTINUED:
HYDRAULIC AND BRAKE SYSTEM OIL FILTERS.
DO NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pres-
sure has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid
under pressure can penetrate the skin, causing serious injury.
Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids. If an
accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before servicing hydrau-
lic system. Failure to do so could result in injury.
Hydraulic fluid is very slippery. Immediately wipe up any spills. Failure to follow this warning may
result in injury to personnel.
Following any hydraulic system maintenance action that results in hydraulic system being opened,
replacement of hydraulic reservoir return filters is required after 100 hours of operation.
Replace the hydraulic system and brake system filters after the first 100 hours of operation, thereafter at 1000
hour intervals. More frequent replacement is needed only as a result of oil sampling by the AOAP.
10. OIL CAN POINTS. Lubricate storage compartment hinges, locks, and fuel cap and right-side step assembly
pivot points as required with hand oiler (OE/HDO).
11. ARMY OIL ANALYSIS PROGRAM (AOAP).
Engine and transmission system oil must be sampled every 50 hours of operation or 90 days,
whichever occurs first, for Active Army Units. Reserve and National Guard activities will use 50
hours or 180 days, whichever occurs first, as prescribed interval. Hydraulic system oil must be sam-
pled annually. Sampling will be performed as prescribed by DA Pam 738-750.
Do NOT sample engine and transmission oil until 50 hours after 100-hour initial break-in services.
Steps to sample engine, transmission, and hydraulic system oil are the same.
Open remote hydraulic control compartment door (refer to View F).
Take sample of oil as follows:
(1) Start engine and bring to operating temperature (TM 10-3930-675-10).
(2) Remove cap from discharge port of sampling valve. Clean sampling valve with a clean rag.
(3) Turn knob of sampling valve 1/4 turn clockwise and collect oil sample in a clean container.
(4) Install cap on sampling valve discharge port.
(5) Shut down engine (TM 10-3930-675-10).
(6) Close remote hydraulic control compartment door.
(7) Submit sample to AOAP laboratory.
