1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of your WARN M8000-S Series Electric 12V Winch. The M8000-S is designed for vehicle recovery and utility applications, featuring an 8,000 lb (4 Ton) pulling capacity and 100 feet of 3/8" diameter synthetic Spydura rope. Please read this manual thoroughly before using the winch.
2. Safety Information
WARNING: Failure to follow these instructions may result in serious injury or property damage.
- Always wear gloves and eye protection when operating the winch.
- Never exceed the rated pulling capacity of the winch.
- Keep hands and clothing clear of the rope, fairlead, and drum during operation.
- Ensure the vehicle's engine is running during winching to maintain battery power.
- Inspect the synthetic rope and all rigging components before each use for damage or wear.
- Do not use the winch for lifting people or as a hoist.
- Always use a tree trunk protector or anchor strap when attaching to a tree, and a dampener blanket over the rope during recovery.
- Disconnect the remote control when not in use to prevent accidental operation.
3. Product Components
The WARN M8000-S winch system includes the following main components:
- Winch Assembly: Motor, gear train, drum, and braking system.
- Synthetic Rope: 3/8" diameter x 100' length Spydura synthetic rope with a ballistic nylon sliding sleeve.
- Hawse Fairlead: Polished aluminum fairlead to guide the rope.
- Remote Control: Rubberized, ergonomic pistol-grip remote for safe operation from a distance.
- Contactor Control Box: Houses the electrical contactor for power distribution.
- Hook: Heavy-duty clevis hook for attachment to recovery points.
- Wiring Kit: Cables for connecting the winch to the vehicle's battery.

4. Installation
Proper installation is crucial for the safe and reliable operation of your WARN winch. It is recommended that installation be performed by a qualified technician.
4.1 Mounting the Winch
- Select a Mounting Location: The winch must be mounted to a structurally sound winch bumper or mounting plate capable of withstanding the full rated pulling capacity. Ensure the mounting surface is flat and provides adequate clearance for the winch and rope.
- Position the Winch: Place the winch onto the mounting surface, aligning the mounting holes.
- Secure the Winch: Use high-grade bolts, washers, and nuts (typically Grade 5 or better) to secure the winch. Torque all fasteners to the manufacturer's specifications.
- Install Fairlead: Attach the hawse fairlead to the bumper or mounting plate, ensuring it is centered with the winch drum.

4.2 Electrical Connections
- Disconnect Battery: Before making any electrical connections, disconnect the negative terminal of the vehicle's battery to prevent accidental short circuits.
- Mount Control Box: Secure the contactor control box in a location that is protected from elements and allows for easy access to the remote control port.
- Connect Winch to Control Box: Connect the motor leads from the winch to the corresponding terminals on the control box. Refer to the wiring diagram provided in the full user guide for specific connections.
- Connect Control Box to Battery: Connect the main power cables from the control box to the vehicle's 12V battery. Ensure proper polarity (red to positive, black to negative). Use appropriate gauge wiring and ensure all connections are tight and corrosion-free.
- Reconnect Battery: Once all connections are secure, reconnect the negative battery terminal.

5. Operation
Familiarize yourself with the winch controls and safety procedures before attempting any recovery operation.
5.1 Preparing for Winching
- Assess the Situation: Evaluate the recovery scenario, including the weight of the vehicle, terrain, and available anchor points.
- Select Anchor Point: Choose a strong, stable anchor point (e.g., another vehicle, a large tree, or a rock). Use a tree trunk protector or recovery strap to protect natural anchors.
- Unspool Rope: Disengage the clutch (if applicable) and pull out enough synthetic rope to reach the anchor point. Ensure at least five wraps of rope remain on the drum.
- Attach Hook: Securely attach the hook to the anchor point using a shackle or other appropriate recovery gear.
- Engage Clutch: Re-engage the clutch.
- Dampener Blanket: Place a winch dampener blanket or heavy jacket over the middle of the synthetic rope to absorb energy in case of rope failure.

5.2 Winching Procedure
- Connect Remote: Plug the remote control into the control box.
- Clear the Area: Ensure all bystanders are at a safe distance.
- Begin Winching: With the vehicle's engine running, slowly press the "IN" button on the remote control to begin winching. Maintain a slight load on the rope to ensure even spooling.
- Monitor Operation: Continuously monitor the rope, anchor point, and winch for any signs of stress or malfunction.
- Stop and Reposition: If the vehicle is not moving or the winch is straining excessively, stop winching, reassess the situation, and consider alternative recovery methods or repositioning the anchor.
- Complete Recovery: Once the vehicle is recovered, release tension on the rope, disconnect the hook, and carefully respool the rope.

6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your WARN M8000-S winch.
- Rope Inspection: Regularly inspect the synthetic rope for cuts, abrasions, fraying, or discoloration. Replace the rope if any damage is found.
- Clean Winch: After use, especially in muddy or dusty conditions, clean the winch with a mild detergent and water. Avoid high-pressure washing directly on electrical components.
- Electrical Connections: Periodically check all electrical connections for tightness and corrosion. Clean and apply dielectric grease as needed.
- Fairlead: Ensure the hawse fairlead is clean and free of burrs or sharp edges that could damage the synthetic rope.
- Lubrication: Refer to the full WARN user manual for any specific lubrication requirements for internal components.
- Storage: If the winch is not used frequently, consider covering it to protect it from UV exposure and environmental elements.
