TROUBLESHOOTING
Cables do not stay in grooves on nylon
spools when operating.
Cable ratchets may need o󰀨set
adjustment.
Check level of tension channels for
proper tension.
Set screw may be loose allowing tarp
to “slip or walk.” Recenter tarp between
end caps. Tighten set screw.
Tarp doesn’t wind smooth. Binds on one end
or both ends.
Spools may be binding on roll tube,
clean and reinstall.
Cannot fully open tarp. (On boxes wider than
11’ 6” it is normal for tarp to stop 6” to 8”
from edge of box.)
Cable tension may be too loose. Check
level of tension channels for proper
tension.
Tarp has been altered or improperly
repaired.
Tarp sags in middle area. Cable tension may be too loose. Check
level of tension channels for proper
tension.
Holes or tears in tarp. Contact your local Agri-Cover dealer for
replacement tarp or tarp repair kit.
When new tarp or parts are needed
replace with original Agri-Cover parts.
