6: INITIAL OPERATION AND ADJUSTMENTS
A. Unroll cover and place rear bar into strikes on
side rails. Press down on rear bar to close
(20-30 lbs pressure). The cover fabric may be
tight. Over time, under tension, it will conform
to its hardware and loosen slightly. If rear bar
is too hard to push down, adjust tensioners
equally as needed to close.
Strike at rear
B. Close tailgate slowly, top of tailgate should
fit snug under rear bar. If cover impedes
normal tailgate operation, raise side rails by:
loosening rear clamps, adjusting side rail up
and then tightening clamps. If there is a gap
between tailgate and cover, adjust side rails
lower.
IMPORTANT: Verify each clamp is torqued to
20 ft-lbs or value specified in special
instructions (if supplied). Start behind cab
and work toward tailgate.
C. Check cover tension by releasing latch and
then opening and closing rear bar several
times. It should snap when closing. Cover
fabric should be tight without sagging between
the bows.
D. If adjustment is needed, roll cover open
then either: turn tension adjuster clockwise
to loosen or turn tension adjuster counter
clockwise to tighten. Ensure to adjust
tensioners equally.

Turn Clockwise
To Tighten Cover
Turn Counter

E. Always seal both sides of cover with hook
and loop system. For detailed operating
instructions see pages 13 and 14.
Tip: Reasons to keep cover drum tight:
1. Increases longevity
2. Decreases noise
3. Enhances appearance

TROUBLESHOOTING
PROBLEM SOLUTION
Cover too loose Turn both tension adjusters counter clockwise
to move front bar forward (see Step 6D).
Cover too tight Turn both tension adjusters clockwise to
move front bar back (see Step 6D).
Gap between rear bar and tailgate Side rails set too high (see Step 6B).
Top of tailgate hits rear bar when attempting to
close
Raise side rails at rear of box until tailgate
closes without pushing rear bar up (see Step
6B).
Cover too narrow Check if side rail is level. If side rail tilts up:
loosen and lower clamp, engage teeth and
then retighten clamp (see Step 1H).
Cover too wide Check if side rail is level. If side rail tilts down:
loosen and raise clamp, engage teeth and
then retighten clamp (see Step 1H).
Lopsided cover (too much on one side) Check if front bar is centered between side
rails (see Step 5E).
Dual locking system doesn’t engage Check side rails for height and level (see
Step 1K). Inspect latches for jammed or
broken parts.

the installation and operating instructions.
• Periodically check and/or retighten clamps as needed.
• Periodically check dual locking system to ensure latches fully engage side rails.
• Periodically inspect the condition of cover assembly and all parts. Check for loose bolts and
parts, tighten if needed. Test the operation to ensure parts are functioning properly and cover
is in top operational condition.
• If latch has been damaged, replace with new one.

• Do not cover cargo higher than the cover.
• Do not place object(s) on or against the cover or its framework at any time.
• Always secure cargo to avoid shifting and damaging the cover or its parts.
• Remove snow or debris from top of cover before rolling.
• Do not use the cover’s framework to tie down cargo.
• Never stand, sit or ride on the cover or allow others to do so.

people or animals to occupy box with the cover closed.
• When towing vehicle backward, cover must be rolled fully open and secured with storage
straps.
• Always finish securing the cover by sealing sides.
• Use caution when operating cover in windy conditions.
