2. Product Overview and Components
The Daiwa RS 4000 is a versatile spinning reel designed for both saltwater and freshwater fishing. It features a robust construction, smooth operation, and a powerful drag system.
Key Components:
- Spool: Holds the fishing line.
- Drag Knob: Adjusts the drag tension on the spool.
- Bail Arm: Guides the line onto the spool during retrieval and is opened for casting.
- Handle: Used to retrieve the line. Can typically be switched for left or right-hand retrieve.
- Anti-Reverse Lever: Engages or disengages the anti-reverse function, preventing the handle from turning backward.
- Reel Foot: Attaches the reel to the fishing rod.

3. Setup
3.1 Attaching the Reel to a Fishing Rod
- Loosen the reel seat nut on your fishing rod.
- Slide the reel foot of the Daiwa RS 4000 into the reel seat.
- Tighten the reel seat nut securely until the reel is firmly attached and does not wobble. Do not overtighten.
3.2 Spooling Fishing Line
- Open the bail arm.
- Tie the end of your fishing line to the spool using an arbor knot or similar secure knot. Trim any excess tag end.
- Close the bail arm.
- Hold the line under slight tension and begin to reel slowly, ensuring the line lays evenly on the spool.
- Fill the spool to approximately 1/8 inch (3mm) from the rim. Overfilling can cause tangles and casting issues.

4. Operating Instructions
4.1 Casting
- Hold the fishing rod and reel comfortably.
- Press the line against the rod handle with your index finger.
- Open the bail arm.
- Swing the rod forward, releasing your index finger at the desired point to cast the lure or bait.
- As the lure or bait hits the water, close the bail arm manually or by turning the handle.
4.2 Retrieving
Turn the handle clockwise (for right-hand retrieve) or counter-clockwise (for left-hand retrieve) to reel in the line. Maintain a steady retrieve speed appropriate for your fishing technique.
4.3 Adjusting the Drag
The drag system allows line to be pulled from the spool when a fish pulls hard, preventing line breakage. Adjust the drag by turning the drag knob on the front of the spool.
- Turn clockwise to increase drag tension (tighter).
- Turn counter-clockwise to decrease drag tension (looser).
Set the drag to approximately one-third of your line's breaking strength. Test the drag by pulling line directly from the spool.
5. Maintenance
Regular maintenance will extend the life and performance of your Daiwa RS 4000 reel.
5.1 Cleaning After Use
- After each use, especially in saltwater, rinse the reel with fresh water. Do not submerge the reel.
- Wipe down the exterior with a soft, damp cloth to remove salt, dirt, and debris.
- Allow the reel to air dry completely before storage.
5.2 Lubrication
Periodically apply a small amount of reel oil to moving parts such as the bail arm pivot points and handle shaft. Use reel grease for gears if disassembling, but general users should avoid full disassembly unless experienced.
5.3 Storage
Store your reel in a dry, cool place away from direct sunlight and extreme temperatures. Consider using a reel cover to protect it from dust and scratches.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Line tangles or bird's nests | Overfilled spool, incorrect line tension during spooling, twisted line, improper casting technique. | Remove excess line, respool line with proper tension, check for line twist, practice casting technique. |
| Stiff handle or grinding noise | Dirt/debris in gears, lack of lubrication, damaged internal components. | Clean and lubricate the reel. If problem persists, professional service may be required. |
| Drag slips or is inconsistent | Drag washers are dry, dirty, or worn; drag knob not tightened correctly. | Clean and re-grease drag washers (use specialized drag grease). Ensure drag knob is properly adjusted. |
