OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED
FORDING - CONTINUED
Check bottom surface of water to ensure it is hard enough to be forded without
exceeding maximum fording depth.
Ensure that engine is operating properly.
Lubricate unpainted surfaces to guard against rust and deterioration.
Place inter-axle lockout control valve lever in LOCK position.
Place transmission in a low gear and enter water slowly.
Ford at speeds of 3-4 mph (5-6 kph).
When vehicle emerges from water, apply brakes a few times to dry brake linings.
Ensure that brakes are working properly before driving at normal speeds.
Place inter-axle lockout control valve lever in UNLOCK position.
Allow engine to run for awhile to drive out any accumulated water.
Drain or dry any area where water has accumulated.
Check all fluids for signs of contamination and for proper levels (WP 0016 00).
If vehicle has been operated in salt water, rinse undercarriage immediately. Allow
exterior to dry and check for evidence of salt accumulation. Use a clean, damp cloth
to immediately remove all salt accumulation.
Notify Unit Maintenance that after-fording lubrication is required.
OPERATE IN SANDY OR DUSTY CONDITIONS
Maintain steady, even movement with transmission in lower gears with inter-axle lockout
control valve lever in LOCK position. Try to keep vehicle rolling without straining
engine and powertrain.
If vehicle gets stuck, reduce tire pressure to gain additional traction. Reduce pressure in
front tires to 50 psi (345 kPa) and pressure in rear tires to 45 psi (310 kPa). Inflate tires to
normal pressures once vehicle is freed.
If vehicle bogs down, after tire pressure has been reduced, place boards, brush, canvas, or
similar materials under and in front of tires after shoveling a clear path ahead of each tire.
This should improve traction.
If these efforts fail and it becomes evident that vehicle will not free itself, have another
vehicle tow stuck vehicle (WP 0006 00).
