2: Be sure to use only cleaners, waxes, etc., which are labeled ''sate for use on plastics". Make sure dial chemicals or substances, which are not labeled "safe for plastics", do not come in contact with your UNDERCOVER. Failure to do so could cause discoloration and or structural damage to your UNDERCOVER and will void your warranty.

3: Paint rubbing of the truck is normally not a problem, but is always a possibility with any tonneau. To insure less chance of possible paint rubbing of the truck, it is suggested to install a tailgate protector and adhere Cab Skin®, Scotch Cal®. or similar product to the truck bed. These products can provide added assurance against paint rubbing.

Step 2: Use two of the holes in rear bracket which are unobstructed by the truck bed. (there will be three to choose from), one hole as far forward as possible and one hole as far back as possible (this will vary depending upon truck model).

Step 3: Place a 5/16'' x 1 1/4'' bolt with a 5/16" lock washer and a 5/16" washer through the hole in bracket. Place aluminum clamp on backside of bracket behind the bed lip of the truck. Thread the bolt into the clamp and tighten being careful not to let the clamp twist while tightening (sheet 1 figures 2 and 3). Make sure bracket is held down tightly against truck bed rail before tightening. Repeat procedure for second hole. Installation bracket bolts must be tightened to at least 15-ft./lbs. or 180-in./lbs. of torque. Normal installation does not require the use of a torque wrench. But it is a good idea to compare how tight you are currently tightening the bolts with the tool you are using with a torque wrench just so you can get ''the feel" of how tight 15-ft./lbs. or 180-in./lbs.of torque actually is. WARNING! Bolts must be tightened to 15ft./lbs - 180-in/lbs. to prevent any movement of the bracket on the truck bed. Bolts must be re-checked for tightness periodically. Failure to do so could cause serious damage to both the truck and / or your UNDERCOVER.

Step 4: Repeal steps 1 and 2 for opposite side.

Step 5: Find your model of truck from sheet 2 figures 4 or 5 and position front bracket accordingly. Using holes in front bracket designated for your truck on sheet 2 figure 6, repeat step 3, AGAIN MAKING SURE BOLTS ARE PROPERLY TIGHTENED. This position is a good starting point, but some adjustment may be necessary due to variations in truck beds.

Step 6: Repeat step 5 for opposite side.

Step 7: Place tonneau on truck positioning female hinges on tonneau over tangs on front brackets and install split rings into holes in tangs on front brackets (sheet 3 figure 7). BE SURE TO INSTALL SPLIT RINGS BEFORE ATTACHING THE HYDRAULIC STRUTS IN STEP 8.

Step 8: Install hydraulic struts making sure LARGE end of strut is attached to the tonneau. and SMALL or rod end is attached to the ball stud on rear bracket (sheet 3 figure 8}.

Step 9: Be sure that the front flap seal hangs over the bulkhead of the truck and is not rolled under the tonneau after installation. If flap seal is rolled under the Tonneau, open the tonneau and from the inside use a yardstick or something similar to push the flap seal out from under the tonneau and over the bulkhead
(sheet 3 figures 9 and 10).

Step 10: Close tonneau and check length on the truck. There should be 1/4" gap between the tailgate and the tonneau. If this is not correct, adjust by moving front brackets forward or back to achieve correct length. Front brackets may also have to be adjusted to ''square up'' tonneau on some truck beds.

Step 11: Adjust lock strikes. When adjusted properly you should be able to turn the key to the locked position without having to push down on the tonneau. There should be a very slight amount of play between the lock cam and lock strike. A good rule of thumb is to adjust the lock to have approximately 1/8'' gap between the cam and lock strike with the truck tailgate down. This usually gives you the proper adjustment after the tailgate is shut (sheet 1 figure 2).
