6. Setup and Installation
Proper installation is crucial for the safe and effective operation of your CURT hand winch.
6.1 Mounting the Winch
- Select a Location: Choose a mounting location on your trailer or desired surface that is structurally sound and can support the maximum load capacity of the winch (1,700 lbs). The location should allow for full rotation of the handle and clear path for the strap/cable.
- Position the Winch: Place the winch base on the chosen surface. The base features slotted holes for flexible mounting.
- Mark Drill Points: Use the slotted holes on the winch base as a template to mark the drilling points on the mounting surface.
- Drill Holes: Drill appropriate size holes for your mounting hardware (bolts, nuts, washers - not included). Ensure the holes are clean and free of burrs.
- Secure the Winch: Attach the winch to the mounting surface using high-strength bolts, lock washers, and nuts. Tighten all fasteners securely. Periodically check the tightness of mounting hardware.
6.2 Attaching Winch Strap/Cable
(Winch strap or cable is sold separately)
- Prepare Strap/Cable: Ensure your winch strap or cable is in good condition, free from fraying, cuts, or kinks.
- Feed Through Drum: Locate the attachment point on the winch drum. Feed the end of your strap or cable through the slot or attachment hole on the drum.
- Secure Attachment: Securely fasten the strap or cable to the drum using the provided hardware or by following the strap/cable manufacturer's instructions. Ensure it is tightly wound onto the drum.
- Wind Evenly: Manually crank the handle to wind the strap or cable onto the drum, ensuring it spools evenly and tightly. Avoid overlapping or loose wraps.
7. Operation
Follow these steps for safe and effective operation of your CURT hand winch.
7.1 Winding In (Pulling/Lifting)
- Engage Locking Lever: Ensure the ratcheting locking lever is engaged in the forward (winding in) position. This prevents the drum from unwinding unintentionally.
- Attach Load: Securely attach the hook of your winch strap/cable to the item you wish to pull or lift. Ensure the attachment point on the load is strong and appropriate.
- Crank Handle: Grasp the 8-inch handle firmly and begin to crank clockwise (or as needed for your setup) to wind the strap/cable onto the drum. Apply steady, even pressure.
- Monitor Load: Continuously monitor the load and the winch for any signs of strain or malfunction. Do not exceed the 1,700 lbs capacity.
- Maintain Even Spooling: Guide the strap/cable to ensure it spools evenly across the drum. Uneven spooling can damage the strap/cable or the winch.

7.2 Winding Out (Releasing Load)
- Control Release: To release the strap/cable and lower the load, carefully disengage the locking lever. Some winches may require slight forward cranking to release tension before disengaging.
- Maintain Control: Always maintain control of the handle. The load will exert force on the handle as it unwinds. Do not let the handle spin freely.
- Gradual Release: Release the strap/cable gradually and in a controlled manner to prevent sudden drops or uncontrolled movement of the load.
- Re-engage Lock: Once the desired amount of strap/cable is released or the load is fully lowered, re-engage the locking lever to secure the drum.

8. Maintenance
Regular maintenance will extend the life and ensure the safe operation of your CURT hand winch.
- Cleaning: After each use, especially in marine environments, clean the winch to remove dirt, salt, and debris. Use fresh water and a mild detergent if necessary. Dry thoroughly.
- Lubrication: Periodically apply a light coat of grease or lubricant to the gears and moving parts to ensure smooth operation and prevent corrosion. Avoid over-lubrication.
- Inspection: Regularly inspect the winch for:
- Loose or damaged mounting hardware.
- Wear or damage to gears, pawls, or the drum.
- Corrosion on any metal parts, despite the zinc plating.
- Damage to the handle or grip.
- Condition of the winch strap/cable (if applicable). Replace if frayed, kinked, or damaged.
- Storage: When not in use, store the winch in a clean, dry place to protect it from the elements.
9. Troubleshooting
This section addresses common issues you might encounter with your hand winch.
| Problem | Possible Cause | Solution |
|---|---|---|
| Winch is hard to crank | Lack of lubrication; excessive load; damaged gears. | Apply lubricant to gears and moving parts. Reduce load if exceeding capacity. Inspect for damage; replace if necessary. |
| Winch drum does not hold tension (slips) | Locking lever/pawl not engaging; worn pawl or gear teeth; debris in mechanism. | Ensure locking lever is fully engaged. Clean debris from pawl and gear area. Inspect for wear; replace worn components. |
| Strap/cable spools unevenly | Improper winding technique; damaged drum. | Manually guide the strap/cable during winding to ensure even layers. Inspect drum for deformities. |
