Key Safety Concerns

• Sinking and Drowning: AUTVs are vulnerable to sinking due to structural failure or a breach of its waterproof seals.
• Rollover and Instability: AUTVs have a high center of gravity and a narrow wheelbase, making them inherently unstable and prone to tipping over.

• Occupant Ejection and Crushing: In the event of a rollover, occupants face a high risk of being thrown from the vehicle or crushed by its weight.

Operator's Manual: Your Best Resource

The operator’s manual is tailored to your specific vehicle and provides essential guidance on safe operation, maintenance procedures, and manufacturer-approved practices. Always review it before operating an AUTV.

The operator's manual includes:

• Basic safety rules cover how to use the vehicle properly, wear the right gear like helmets and life jackets, keep passengers seated with seat belts, and understand all the controls to avoid accidents.
• Land and water operation guidelines cover safe driving on terrain and water, proper mode transitions, and critical use of drain plugs to maintain vehicle performance and safety.
• Maintenance and troubleshooting cover regular service schedules, safety inspections, problem-solving steps, care for key systems, and proper storage to keep the vehicle running smoothly on land and water.
• Technical specifications and warranty include key vehicle details, payload limits, coverage terms, and guidance on when to seek authorized service support.

PPE: Personal Flotation Device (PFD)

A U.S. Coast Guard approved PFD must be worn at all times when operating equipment on water to ensure safety and meet regulatory standards.

• If operating an AUTV on the water, you are required to wear a U.S. Coast Guard (USCG) approved Personal Flotation Device (PFD) in addition to the appropriate clothing.
• If an AUTV is equipped with ROPS, always use the seat belt when traveling on land, remove when on the water.
• Ensure all passengers are wearing an approved USCG PFD.

Warning Labels

All models feature labels that highlight operating hazards and offer important safety instructions specific to the vehicle.

Information on water operation, proper fueling procedures, and floor plan placement is clearly marked on color-coded labels located throughout the vehicle.

Know Your Ride: Controls, Fueling, and Maintenance

ControlsBefore operating an AUTV, make sure you're familiar with all vehicle controls, especially the brakes and steering system. Most AUTVs use a skid steering system, which requires precise handling to turn safely.

MaintenanceOperators are responsible for ensuring the AUTV is kept in safe operating condition by confirming required routine maintenance is completed by an approved service provider.

Fueling SafetyAlways start long trips with a full tank and spare fuel in a watertight container. Never overfill, fuel expanding from heat can overflow and create serious hazards.

Pre-Ride Inspection

Follow all pre-operation and daily checks as outlined in the operator's manual, including the TCLOC process, plus the additional safety steps listed below.

• Before heading out, inspect all emergency supplies, including tools, first aid kit, fire extinguisher, and any other essential items. Ensure your communication device works in the area you’ll be traveling and test all battery-powered equipment for reliability.
• Communicate your trip plan to your supervisor.
• If you plan to operate on water, ensure all drain plugs are securely installed and tightened to prevent flooding or equipment damage.

Safety Equipment

Before operating an AUTV, make sure you’re equipped with all required safety gear, including:

• Hard hat with chin strap
• Face shield, goggles or safety glasses.
• Paddle.
• Bailing device.
• Approved PFD(s).
• Communication device.
• Tool Kit.

• Fire extinguisher.
• First aid kit.
• Extra clothing.
• Navigation device.
• Sound making device.
• Tow Rope.

Turning

Unlike cars, AUTVs use a skid steering system that enables turning without changing the direction of the wheels. When the operator steers to one side, the wheels on that side are braked, causing the vehicle to pivot in that direction.

Sharp turns, especially at high speeds or with heavy loads, can lead to rollovers and serious injury. Always reduce speed before turning and avoid sudden or hard braking during the maneuver. During turns, the rear of the vehicle swings outward in the opposite direction of the turn. This swing is more pronounced in 8-wheel models than in 6-wheelers. Always use caution to avoid striking people or objects with the rear end of the vehicle.

Hill Operation Safety

Avoid sudden acceleration or braking on slopes, this can lead to rollover and serious injury. Always follow incline limits in the owner’s manual; most AUTVs should not be driven on slopes steeper than 30 degrees.

Uphill Operations: Always approach hills head-on to reduce the risk of sliding sideways or rolling over. Use slow, steady acceleration to maintain traction. If traction is lost and the vehicle begins to slide, either sideways or backward, apply the brakes gently and evenly to regain control and stop safely.

Downhill Operations: Always approach hills head-on to reduce the risk of sliding sideways or rolling over. Use slow, steady acceleration to maintain traction. If traction is lost and the vehicle begins to slide, either sideways or backward, apply the brakes gently and evenly to regain control and stop safely.

Cargo Securement

When carrying cargo and passengers:

• Keep cargo low and evenly distributed to maintain vehicle stability.
• Use extreme caution on inclines and during sharp turns, heavy or high loads increase rollover risk.
• Be prepared to shift occupant weight forward or have passengers exit the vehicle when climbing steep terrain.
• Secure all cargo to prevent shifting during operation.
• Never mount heavy fixtures (e.g., spray tanks or stands) to the upper body without proper frame support, this can deform the body and cause tire interference or wear.

Amphibious Operation: Water Operation Safety Guidelines

AUTVs are self-propelled, and designed to navigate calm water, provided key safety precautions are followed.

• Ensure all drain plugs are properly installed and confirm that each occupant has an approved personal flotation device. Once the vehicle is afloat, visually inspect the interior for any signs of water intrusion before proceeding further.

• Ensure the operator and all passengers wear approved USCG PFDs.

• Do not use seat belts or any restraining devices while the AUTV is afloat.
• Never attempt to navigate bodies of water with strong currents. Avoid water travel during high winds or unstable weather conditions.
• Do not operate an AUTV in water if it’s equipped with tracks, unless an outboard motor is also installed. Tracks alone do not provide water propulsion.
• Use caution around submerged obstacles, which may destabilize or overturn the vehicle.
• Ensure rear cargo is evenly distributed to maintain balance.

The rear compartment of all 6-wheel Argo vehicles has a maximum load capacity of 140 lbs. Exceeding this limit reduces vehicle stability on inclines and significantly increases the risk of rolling backward when climbing. Never exceed the rated weight capacity in the rear compartment.

Amphibious Operation: Water Entry and Exit Guidelines

Enter and exit water at a gradual, stable bank, approaching perpendicularly and avoiding steep drop-offs.

• Always enter and exit water at a firm, gradual bank, approaching the shoreline at a perpendicular angle.
• Before entering water deep enough to float the vehicle, unlatch all seat belts and restraining devices.
• Carefully assess the slope and drop off at the water’s edge. If either is too steep, reverse and select a safer route.
• When exiting the water, choose a shoreline that is flat and free of rocks, stumps, or other obstacles.
• Steer so both front wheels contact the shore simultaneously, then accelerate slowly until fully clear of the water.
• If the vehicle is equipped with a ROPS, refasten seat belts once back on land.

Never operate an Argo 6x6 in water if it is equipped with a Roll-Over Protective Structure (ROPS). The added top-heavy weight compromises stability and increases the risk of capsizing, which could lead to serious injury or drowning. Only Argo 8x8 models with ROPS are approved for safe water operation.

Water Operations Hazards

Identifying Water Operations Hazards

A. Fast Current: AUTVs are built for calm water conditions. Their limited propulsion cannot counter fast currents, which can pull the vehicle downstream and out of17 control.B. Submerged Logs & Tree Roots: Submerged logs and tree roots can trap the AUTV and destabilize it, increasing the risk of rollover in water. C. Trees: Low-hanging branches can injure occupants or destabilize the AUTV, increasing the risk of rollover in water. D. Tall Vegetation & Shrubs: Can hide steep banks and drop-offs, making water entry and exit hazardous.
