UNUSUAL TERRAIN OPERATION CONTINUED
Maintenance
0006
1.
Mud. Clean and lubricate all parts as soon as possible after operation in mud (WP 0017).
2.
Sand and Dust. Operation in dusty or sandy areas requires more frequent cleaning and servicing of filters to prevent dust
entering the engine, transmission, fuel system, and hydraulic system. Dust build-up on major components increases the
chance of entry into internal areas and interferes with adequate cooling. Pay particular attention to the following areas:
Lubricate the machine as specified in WP 0017, shortening the service intervals as required.
Carefully clean all areas around the lubrication fittings, fill ports, dipsticks, breathers, and filters with wiping rags
before servicing or inspecting.
Have Field Maintenance service the engine oil filters, fuel filters, transmission filters, hydraulic filters, and air filters.
Check and clean door hinges, fuel filler protective cap and vent, boom and swing locks, and sideshift slides with wip-
ing rags before servicing or inspecting.
Check and clean the cooling pack radiators as specified in WP 0019.
Monitor brake and steering operation for binding (failure to release fully). Report malfunctions to Field Maintenance.
END OF TASK
FORDING PROCEDURES
0006
During an operation, it may be necessary to drive the machine through water. The depth of the water may be from a few inches
to a few feet. Normal fording is allowable up to 40 in. (102 cm) including the bow wake. Perform the following when fording:
Before Fording
0006
CAUTION
Entering water deeper than 40 in. (102 cm) (with wake) can allow water to rise in the engine
compartment to a level where possible engine component damage could occur.
1.
Check the depth of water at its deepest point. Ensure the bottom is even enough for fording. Do not attempt to ford even
the narrowest of streams if it is more than 40 in. (102 cm) including the bow wake.
2.
Set all work tools to their transport position (WP 0005).
3.
Be sure the engine is fully operational.
