The provided document is an installation instruction manual for a Warn M15000 Electric Winch. This manual details the proper procedures for mounting the winch, installing the solenoid pack, making electrical connections, and operating the clutch. It also includes important safety warnings and fabrication instructions for custom mounting plates.
The Warn M15000 Electric Winch is designed for heavy-duty pulling applications, likely for vehicles or industrial uses, given its 15,000 lbs rating. The winch operates on an electric motor, powered by a vehicle's battery system. Its primary function is to provide mechanical pulling force through a wire rope, which is spooled onto a drum. The winch features a clutch mechanism that allows for "free spool" operation, enabling the user to manually pull out the wire rope without engaging the motor, and an "engaged" position for powered winching.
Technical Specifications and Requirements:
- Mounting System Rating: The winch requires a mounting system rated for safe operation at 15,000 lbs. This emphasizes the heavy-duty nature of the winch and the need for robust mounting.
- Mounting Plate Thickness: For custom fabrication, a minimum of 5/16" thick steel plate is required for the mounting plate.
- Fasteners: Grade 5 or better fasteners are specified for mounting. Specific fastener sizes and torques are provided:
- Two 7/16-14 x 1-1/2 grade 5 hex head capscrews with lockwashers for upper and lower drum support holes, tightened to 30 lb. ft. (4.14 Kg-m).
- Two 7/16-14 x 1-3/4 hex head capscrews with lockwashers and flat washers for the bottom (horizontal) flange of the mounting plate and drum support, tightened to 30 lb. ft.
- Battery Requirement: A fully charged "Heavy Duty" battery in the 90 amp/hour rating range (650 or larger cold cranking amps) is required for optimal performance. This highlights the significant power draw of the winch.
- Cable Length: A 72-inch red cable is provided for connection to the positive battery terminal.
- Solenoid Pack: The solenoid pack is a critical component that must be properly grounded to the chassis for the winch to operate. It manages the electrical flow to the motor.
Usage Features:
- Clutch Operation: The winch features a clutch located on the gear housing.
- Engaging the Clutch: To engage the clutch for powered winching, the clutch lever must be rotated counter-clockwise. It is crucial for the clutch lever to be in a "full engaged position" to prevent damage to the winch. If the gears do not align, jogging the motor or drum may be necessary.
- Free Spool: To disengage the clutch and allow for free spooling of the wire rope, the clutch lever must be rotated a full 180 degrees. A critical warning states: "DO NOT ROTATE THE CLUTCH OUT OF THE 'ENGAGED' POSITION WHILE UNDER LOAD. THE BRAKE WILL NOT FUNCTION WITH THE SPOOL IN 'FREE SPOOL'." This emphasizes a key safety aspect, as the brake relies on the clutch being engaged.
- Remote Control: The winch is operated via a remote control, which is used to test forward and reverse operation. Users are warned to keep hands away from the wire rope and hook during testing.
Maintenance Features (Implicit and Explicit):
- Mounting Plate Flatness: The manual advises checking that the mounting plate is flat. If the drum binds or does not rotate freely with the clutch disengaged, shim washers should be placed between the winch and mounting plate until the drum rotates freely. This is a crucial step for proper function and longevity.
- Battery Terminal Cleaning: Before connecting the 72-inch cable, users are instructed to clean the battery terminals. This ensures good electrical contact and prevents power loss or damage.
- Fastener Integrity: The manual explicitly warns against welding the head of any bolt or capscrew used for attaching the winch mounting kit or bumper kit. Welding can cause metallurgical changes, making fasteners brittle and prone to breakage, leading to personal injury or property damage. This highlights the importance of maintaining the structural integrity of the mounting hardware.
- Solenoid Pack Grounding: The solenoid pack must be grounded to the chassis for operation. This is a key electrical connection that needs to be correctly established.
- Cable Management: Small black vinyl boots are provided to cover the nuts and terminals on the motor after electrical connections are made, protecting them from environmental elements and potential short circuits.
Safety Considerations:
The manual is replete with "CAUTION" and "WARNING" notices, underscoring the potential hazards associated with winch installation and operation:
- Installer Responsibility: The installer is notified that the winch user must receive the pamphlet for detailed service information, ensuring that safety and operational knowledge is passed on.
- Pre-Installation Reading: Users are warned not to install the winch before reading and understanding the operator's manual, as it contains important safety information.
- Mounting System Suitability: It is crucial to use a mounting system rated for the winch's capacity. Using an unsuitable mounting kit could lead to failure.
- Fastener Length: To avoid damage to the drum support brackets, users are warned not to use fasteners longer than those recommended.
- Fairlead Attachment: The fairlead should not be fastened directly to the drum supports.
- Welding Fasteners: As mentioned, welding fasteners is strictly prohibited due to the risk of embrittlement and breakage.
- Clutch Engagement: Operating the winch with the clutch not fully engaged can cause damage.
- Clutch Disengagement Under Load: Disengaging the clutch while under load is extremely dangerous as the brake will not function, leading to uncontrolled movement.
- Hands Clear: During testing, hands must be kept away from the wire rope and hook.
In summary, the Warn M15000 Electric Winch is a powerful pulling device requiring careful installation and adherence to specific electrical and mechanical requirements. Its design incorporates features for both powered and manual rope deployment, with robust safety warnings to prevent injury and damage during use. Proper mounting, electrical connections, and clutch operation are paramount for safe and effective performance.
