Frequently Asked Trailer Questions.

1. Why can’t I back my disc brake trailer?
IIf the 7-blade RV electrical plug is not connected to the tow vehicle, the trailer can not be moved backwards. Disc brakes require the “backup” light circuit of the towing vehicle to activate an automatic backing feature on the trailer. The tow vehicle supplies a signal to the trailer automatically when you place your tow vehicle in reverse. Placing your tow vehicle in reverse will block the hydraulic system and prevent the brakes from applying. Taking the tow vehicle out of reverse will unblock the system to allow your trailer brakes to function normally.

2. I still can’t back my disc brake trailer even though I have my RV plug connected to the tow vehicle.
The trailer must be pulled forward to release the surge brakes before placing tow vehicle in reverse.

3. How often should I grease the wheel bearings?
Once a year at the end of your boating season. Your trailer has the Dexter “EZ-Lube” spindle and “Air-Tight” pressurized hub system. This is a sealed and pressurized system and only requires a quick visual inspection to confirm its condition. If you do not see grease leaking around the hub cap, rubber diaphragm plug or inside spindle seal, your system does not need additional grease. If you see grease leaking around the hub cap, rubber diaphragm plug or grease seal. The leak will need to be corrected.

4. Do I have to remove the hub to change wheel bearing grease?
No. The grease can be changed without removing the hub. To change the grease, remove the rubber diaphragm plug and connect a grease gun to the Zerk (grease) fitting. Pumping new grease in will force the old grease out. Continue adding grease until you see the new grease come out around the hub cap opening. Using a clean rag, remove as much grease as possible from inside the hub cap. This will allow the needed air space for the system to operate correctly. Reinstall the rubber diaphragm plug and pressurize.

5. What type of grease should I use for the wheel bearings?
A good quality “High Temperature Lithium Complex” chassis grease.

6. What air pressure should I run in the tires?
Inflation pressures are displayed on the VIN label and the side wall of the tires. Check air pressure when tires are cold.

7. How often should I check tire pressure?
Each time you tow the trailer. Trailer tires lose air at the same rate as car tires, about 1 psi per week minimum.

8. How far forward should the boat sit on the trailer?
On stern drive and outboard boats. There should be 3” of bunk wood extending aft of the transom.

9. Where should the bow stop be positioned on the trailer?
Position the boat first on the trailer to its correct position. Then place the bow stop against the front of the boat and bolt it to the trailer frame.

10. Should I tie the boat down to the trailer?
Yes. It is recommended that the bow and stern be secured to the trailer. The bow eye should be secured down and back to the eyes provided on the trailer frame. This prevents the boat from moving forward during transport. The transom should also be secured to the rear eyes on the trailer frame.

11. Why does my truck blow the battery charge (supply) fuse when I tow my trailer with electric/hydraulic brakes?
The fuse on your tow vehicle may not be large enough. A 30 amp fuse and circuit is required for electric/hydraulic trailer brakes.

12. Should I disconnect the electrical connector before launching?
No. The trailer wiring and lighting system are designed to withstand being submerged with the lights operating.
