HMMWVs have a 30 in (76 cm) shallow water fording capability without the use of a deep water fording kit. However, this capability applies only to fords with a hard bottom. Shallow water fording procedures are divided into three phases: Before operation During operation After operation CAUTION Never attempt shallow water fording unless the water depth is known to be 30 in (76 cm) or less and the bottom is known to be hard. Do not exceed 5 mph (8 kph) during the fording operation. If these guidelines are not followed, damage to the vehicle may result.

If necessary, remove the propeller shafts.

Have unit maintenance remove the front and rear propeller shafts of the disabled vehicle if towing speed or distance will exceed limits.

Why should the fuel filter be drained frequently in conditions of extreme humidity?

High condensation may occur in the fuel system.

You are planning to ford a stream. Recon shows the water depth to be 47 inches. What is the proper transfer case selection for deep fording?

High lock (H/L)

Hook the end fastener to the chain assembly

Hook the end fastener to the chain assembly on the outside of the tire, and secure it with a locking retainer to tighten the chain assembly. Ensure as many cross-link sections as possible lie between the sidewall tread lugs on both sides of the tire.

Emergency Assistance Procedures Render First Aid

If the accident results in injuries, you should: Render first aid to the injured persons immediately. Request help from emergency medical services.

Thermal cutoff

If the motor temperature increases to the point that the motor is overheated, a thermal cutoff switch will automatically shut off the winch. If this occurs, you must wait until the motor has had time to cool (at least 2 minutes) before attempting to resume winch operation. If the winch is not operable after waiting 5 minutes, notify unit maintenance.

Operation in Extreme Weather Conditions Operating in Rainy or Humid Conditions

If the vehicle is inactive for long periods during rainy or humid conditions, metal components can rust rapidly. Fungus may develop in the fuel tanks as well as on soft tops, seats, and other components. Frequent inspections, cleaning, and lubrication are necessary to maintain the operational readiness of vehicles. During prolonged rainy or humid conditions: -Be careful to not spin the wheels when placing the vehicle in motion. In slippery conditions, it may be necessary to place the transfer case in the high lock (H/L) range to avoid spinning the wheels. Refer to the technical manual for additional techniques that are used when operating on unusual terrain. -Drain the fuel filter more frequently. During After Operations PMCS, the fuel filter is drained to remove any water that has collected in the fuel. In extremely humid conditions, there can be more condensation than normal in the fuel system, so the fuel filter may need to be drained more frequently.

Procedures for Hills and Slopes Climbing a Steep Hill (Continued)

If the wheels start to slip, walk the vehicle the last few remaining feet of a hill by swinging the front wheels sharply left and right if the situation permits. This action will provide a fresh bite into the surface and will usually result in enough traction to complete the climb.

Current limiter

If the winch is overloaded during winching operations, a current limiter in the winch will stop the winch. If the winch stops repeatedly, but resumes operation in about 5 seconds, this indicates an overload condition.

Accident-Identification Card Card Distribution

If you are in an accident, you must complete an Accident-Identification Card (DD Form 518) for each of the other parties involved in the accident. If the accident involves a parked vehicle and its owner is not present, summon authorities and wait for them to arrive. The Accident-Identification Card can be secured to the windshield to provide contact information for the vehicle's owner.

Procedures for Shallow and Deep Fords Deep Water Fording

The deep water fording kit allows HMMWVs to ford water up to 60 in (152 cm). However, this capability applies only to fords with a hard bottom. Deep water fording procedures include: Before operation During operation After operation CAUTION Never attempt deep water fording unless the water depth is known to be 60 in (152 cm) or less and the bottom is known to be hard. Do not exceed 5 mph (8 kph) during the fording operation. If these guidelines are not followed, damage to the vehicle may result.

Electric winch

The electric winch is powered by the vehicle's electrical system. For maximum pulling power, operate the winch with the vehicle running and other electrical equipment off. The winch can be operated on battery power alone (engine not running) for short periods, but this will quickly drain the batteries, and power will be limited. The maximum load capacity of the electric winch is 9000 lb.

Recovery Troubleshooting the Electric Winch

The electric winch is powered by the vehicle's electrical system. In normal use, the engine should be running so the electrical load is not placed on the battery alone. In an emergency, the electric winch can be powered by the battery without the vehicle engine running, but this mode of operation will quickly drain the battery. There are two overload protections that will stop the winch to prevent equipment damage: Thermal cutoff Current limiter

Recovery Fairlead Rollers

The fairlead rollers guide the winch cable into and out of the drum and keep the cable from rubbing on the bumper surface.

Recovery Drum

The hydraulic winch drum is a circular drum used to wind or unwind the cable. When using the winch, always keep at least five wraps of cable on the drum. If a load is applied with less than five wraps of cable on the winch, the cable may come loose on the drum.

Procedures for Shallow and Deep Fords Shallow Water Fording - Before Operation

To prepare for shallow water fording, peform the following: Ensure the oil dipstick, transmission dipstick, oil filler cap, and fuel tank cap are secure. Secure all loose objects on the vehicle. Ensure the battery caps are tight. Place the transfer case shift lever in H (high range). If shallow water fording in salt water with the M1123, you must follow the procedure outlined in the manual for disconnecting the slave receptacle. Note: Ensuring the battery caps are tight is not necessary for the newer gel-type batteries since these batteries have no caps.

Procedures for Hills and Slopes Relieving Drivetrain Torque Buildup

When leaving a low-traction surface such as a steep hill and moving onto a high-traction surface (for example, a paved road), drivetrain torque buildup may make it difficult to shift out of a locked range. After shifting the transfer case from a locked range (H/L or L) to high (H) range, back up the vehicle approximately 5 ft (1.5 m) before proceeding to prevent or relieve driveline torque buildup. CAUTION Do not operate with transfer case shift lever in H/L (high/lock) or L (low) range on high traction surfaces where little or no wheel slippage is evident. Damage to drivetrain may occur.

Procedures for Muddy Areas Introduction

When operating in muddy terrain or driving through mud, there are certain actions you should take during each phase of the operation: Before operation During operation After operation

General Rules and Safety Guidelines Follow the Standard Sequence for Placing a Vehicle in Motion

When operating in unusual conditions, follow the standard sequence for placing a vehicle in motion. Perform Before Operations PMCS carefully to ensure your vehicle is in good working order before starting out. Observe basic safe driving practices. This is as important off-road as it is on-road. Pay particular attention to terrain and weather conditions. A paved road surface can be slippery in rainy or snowy conditions. But off-road, such conditions can be even more hazardous. Following safe driving practices is a critical factor in completing your mission.

Procedures for Dusty or Sandy Areas Before Operation

When preparing to operate in sand, perform the following actions: -Adjust tire pressure to 20 psi in the front tires and 30 psi in the rear to increase traction -Place the transfer case in H/L and the transmission in overdrive Overdrive Symbol. -Limit your maximum speed to 30 mph.

Procedures for Shallow and Deep Fords Shallow Water Fording - During Operation

When shallow water fording, you should: Enter the water slowly. Maintain a consistent vehicle speed of 5 mph (8 kph). Exit the water in an area with a gentle slope. CAUTION Decrease speed when entering the water to avoid splashing water into the air intake. If water enters the air intake, the engine may stop and refuse to start. If this occurs, do not continue starting efforts or you may damage the engine.

Operating With Night Vision Goggles Ground Speed Limitations

When using NVGs, you must drive at reduced speed. As a general rule, your maximum speed should be no more than it would be when using blackout lighting. Under most conditions, the maximum safe speed will not exceed 25 mph. Different light levels affect the distance at which you can identify an object. This distance limits the ground speed at which you can safely drive. The type of terrain and road surface are also factors in determining maximum safe speed when using NVGs. Off-road operation and hilly terrain further reduce the maximum speed.

Procedures for Dusty or Sandy Areas During Operation

While operating the vehicle in a dusty or sandy area, perform the following: -Frequently check the air restriction gauge. If the indicator shows red, park the vehicle, stop the engine, and service the air cleaner. -Accelerate slowly so that the wheels do not spin and dig into the sand. -If engine overheating occurs: >Park the vehicle and allow it to idle. >Observe the coolant temperature gauge for steady cooling. >If coolant temperature gauge continues to increase or does not lower, perform troubleshooting procedures to correct the problem. Caution Stop the engine if the coolant temperature gauge increases beyond approximately 250 degrees F (230 degrees for M1123) and/or the overheat lamp illuminates. Failure to comply will result in damage to the engine. Use a wrecker or second vehicle equipped with a winch to recover vehicles mired in deep sand. Do not attempt to "rock" vehicles out of deep sand with quick transmission shift changes. Damage to the transmission will occur.

Recovery Preparing for Winch Operation

Winch preparations will vary depending on the type of recovery. Similar-vehicle recovery operations use the recovery vehicle's winch. When conducting the recovery of a similar vehicle, park the recovery vehicle so that it directly faces the vehicle to be winched. Self-recovery operations using an anchor vehicle use the disabled vehicle's winch. If conducting a self-recovery, locate an anchor point or park an anchor vehicle facing the trapped vehicle's winch. Additional preparations for recovery and anchor vehicles include: Shifting the transmission and transfer case to neutral (N) Applying the parking brake Chocking the wheels Starting the engine Preparations for the disabled vehicle include: Shifting the transmission and transfer case to neutral (N) Releasing the parking brake
