• Drain tubes may become clogged over time and should be
removed and cleaned. To remove the drain tubes, reach under
the canister, grab the drain tube fitting and turn it while applying
light downward pressure. When the retaining tabs align with
notches in the bottom of the canister the Drain Tube and Fitting
will drop out. (FIG. H1)
• Re-tighten your clamp bolts quarterly with a torque wrench to 70 in-lb (5.9 ft-lb.). For excessive driving
or extreme conditions (on rough roads, during high winds, following an emergency stop or evasive
maneuvers) you many need to re-tighten more frequently.
• To help keep your UltraGroove Electric Retractable Tonneau Cover looking it's best, we recommend
washing it the same way you wash your truck. However you should not wax your cover.
• Maintenance of the Release Handle Assembly requires lubrication of the coupler located inside the
canister. This is done during factory assembly but may need to be done from time to time during the life
of your cover.
• A small lubrication hole is provided on the coupler that a fine tipped grease gun can inject a small amount
of grease into. A high quality waterproof wheel bearing grease is recommended.
• To get to the coupler you will need to remove the rail clamps and end caps at the end of the rails. Use the
manual release handle and manually pull the cover out the end of the rails until you have access to the
coupler inside the canister. Grease the coupler, cycle and spin it to distribute lubricant then reverse the
process to re-assemble the cover, being sure to manually push the cover back into place in the canister.
