Bed Liner Installation
You have to make bed liner installation first. So, instructions for bed liner are:

Clean Your Truck Bed
Open your tailgate. You will never find any access on the truck bed with your closed tailgate. Remove all handles and screws from your truck bed. Wash the truck bed. Use cleaning spray or rubbing alcohol (soft detergent with warm water is also useful).
Set Screws
Find the holes to set screws. If there is no gap or hole, use the drill machine. You will surely need to secure your linear with screws.
Dry the Bed
After washing, remove the excess moisture and water from the bed. Take a dry cloth or sponge.
Bed Liner Placing
Then place your bed linear. Fix all the screws and handles properly. Cover the screw holes with caps. Install the cab-side tailgate seals.
Side Rail Installation

Attaching Clamps with Side Rails
Place your side rail on the bed rail. Most of the covers available in the market are with two side rails. Fix the side rails with clamps. Place another clamp at a distance from the previous one.
Secure the Clamps
Clamps do their job by closing the gap between rail and truck. Tighten the clamps properly. The wrench of .5 inch can do it well.
Set the Perfect Rail Alignment
Check the alignment of rails and if you need, readjust them. Push them as they can touch the front of the box. These two rails must be parallelly perfect. Rails must be centered and flat enough. If need to adjust the rails, just loosen the screws and bolts slightly and fix them.
Point to be Noted
Installing side rails is very important. The user cannot set the cover properly for the unbalanced rails out of position. This step will take your time!

Put rubber seals on the side rail. Rubber will provide weather protection (especially from snow and rain).
Set the Cover in Place
Take the cover and put it on the bed rail. Cut the extra portion of your cover. Use the scissors. Set the cover by ensuring the perfect tightness. Don’t make the cover so taut or so loose.
Remove all Gaps
If necessary, add shims to close the gaps on bed rails. To fix the large gaps of 10 mm (more than 3 inches), you can use shim brackets.
Final Steps
Fix the better cover tension by releasing the auto-latch button. (for several times). Tighten every screw, bolt, and clamp. Now keep your cover unfolded. Hand tightened screw is useful for unfolding. Finally, shut the tailgate and keep the cover tight using screws. If the cover comes out of its place, push it.

No Sitting/Standing
Don’t stand or sit on the cover. Never allow others to do the same. Don’t keep any object on the cover framework.
Do Wrapping as Shield
To remove moisture and dust, do the cover wrapping.
Lock the Cover When Needed
While running the car, secure the cover with a manual slide lock. Use safety straps in windy weather.
Further Issues

Call the Professional
