Warning:
- The tonneau cover must be completely secured in the closed position or opened position while driving. DO NOT DRIVE with the cover in a partially opened position.
- Clean the debris before rolling up the tonneau cover.
- Professional installation is highly recommended.
- Periodically check to ensure all clamps remain secure and tight.
- Remove the tonneau cover before towing the truck from the rear.
- Make sure the locking clip on both sides are completely inserted into the side rails to avoid the end of the cover becoming unlatched.
- To reduce noise and jittering, please install weather stripping along the front of the bed and tighten the clamps strongly to make sure there is no gap between the cover and truck.
- The tonneau cover needs to be removed in extreme weather, such as typhoon, hurricane, heavy rain, and hail.
Maintain and Repair
Tension Adjustment:
The cover assembly has been set to a moderate tension to keep the cover tight and wrinkle-free. If you wish to adjust the tension, simply loosen the socket head bolt on the tension plate and slide the plate.

If Cover Doesn't Stay In Latched:
1. Make sure the locking clip is fully inserted. Check both sides.
Diagram showing correctly inserted vs. not fully inserted locking clip.
2. Adjust the tension control unit towards the tailgate at both sides.

3. If the locking clip is still not fully inserted, loosen mounting clamps and adjust side rails close to the cover rear latch end.
4. Re-tighten mounting clamps after the cover is latched.
