Setup and Installation
Follow these steps to properly install your Fastway Flash BM DT-BM4200 Fixed Aluminum Ball Mount:
- Prepare the Hitch Receiver: Ensure your vehicle's hitch receiver is clean and free of debris.
- Insert Ball Mount: Slide the shank of the Fastway Flash BM into your vehicle's hitch receiver. The ball mount can be oriented with the drop or rise position depending on your trailer's coupler height.
- Secure with Hitch Pin: Align the pin hole on the ball mount with the pin hole on the hitch receiver. Insert a suitable hitch pin (not included) through both holes and secure it with a clip or lock. (Refer to Video 1 for visual demonstration of this step).
- Install Hitch Ball (Sold Separately): If not already installed, attach a hitch ball with a 1-inch shank to the ball mount. Ensure the hitch ball is tightened to the torque specifications provided by the hitch ball manufacturer.
- Verify Connection: Double-check that the ball mount is securely fastened in the receiver and the hitch ball is properly installed.
Operating Instructions
Once installed, the Fastway Flash BM is ready for towing. Always adhere to safe towing practices.
- Connect Trailer: Carefully back your tow vehicle to align the hitch ball with the trailer coupler. Lower the trailer coupler onto the hitch ball, ensuring it is fully seated.
- Secure Coupler: Engage the coupler latch and insert any required safety pins or locks to prevent accidental detachment.
- Attach Safety Chains: Connect the trailer's safety chains to your vehicle's hitch chain loops, crossing them underneath the coupler.
- Connect Trailer Wiring: Plug in the trailer's electrical connector to the vehicle's receptacle. Test all trailer lights (brake, turn signals, running lights).
- Pre-Tow Inspection: Before driving, perform a final check of all connections, ensuring they are secure and free from obstruction. Verify tire pressure on both the tow vehicle and trailer.
- Driving with Trailer: Drive cautiously, allowing for increased braking distances and wider turns. Avoid sudden maneuvers.
Maintenance
Proper maintenance will extend the life of your Fastway Flash BM ball mount.
- Cleaning: After each use, especially in corrosive environments (saltwater, road salt), clean the ball mount with mild soap and water. Rinse thoroughly and dry.
- Inspection: Regularly inspect the ball mount for any signs of cracks, bends, excessive wear, or corrosion. Pay close attention to the hitch pin hole and the ball shank hole.
- Storage: Store the ball mount in a dry place when not in use to prevent unnecessary exposure to elements.
- Lubrication: While the aluminum body does not require lubrication, ensure the hitch ball shank threads are clean and properly lubricated before installing the hitch ball.
Troubleshooting
This section addresses common concerns and issues you might encounter.
| Issue | Possible Cause | Solution |
|---|---|---|
| Ball mount does not fit into receiver. | Receiver opening is obstructed or incorrect size. | Clear any debris from the receiver. Ensure your receiver is a standard 2-inch square opening. |
| Hitch ball does not fit into ball mount hole. | Incorrect hitch ball shank diameter. | This ball mount requires a hitch ball with a 1-inch shank diameter. Verify your hitch ball's specifications. |
| Excessive rattling or movement of ball mount in receiver. | Loose fit in receiver; lack of anti-rattle device. | While this specific model does not include an integrated anti-rattle feature, you can purchase aftermarket anti-rattle devices or hitch tighteners to reduce movement. Ensure the hitch pin is fully secured. |
| Corrosion or pitting on surface. | Exposure to harsh elements without proper cleaning. | Clean the ball mount regularly, especially after exposure to salt or chemicals. While aluminum is corrosion-resistant, surface pitting can occur if not maintained. |
