#1 - End of Season Care
Remove the conveyor system after every season to clean. Power wash it before storing. Don't leave fertilizer on equipment during the off-season. This is the #1 cause of problems.
#2 - Belt Tension

Run your belts LOOSE!
Belts naturally shrink with age. Overtightening may damage rollers, bearings, and belt splines. Back them off as needed.

BEFORE FOLDING, make sure you can see the belt zipper. Avoid the folding area with the spline, both inside the tube and outside. Store with zipper visible in the off-season.

Check weekly to ensure belts are tracking at all rollers. For rollers that are hard to see, shut the belt off. Unless you've adjusted belt tension, you shouldn't see any changes with tracking.

Belt Tension
BELT TENSION - Lower
Lower Conveyor: There should be droop or slack between each return roller on the bottom side of the conveyor. If it is strung tight like a guitar string, it's too tight!
BELT TENSION - Upper
Upper Conveyor: If the belt is rubbing on the composite lumber when running, it's too tight! This lumber is strictly a guide for belt tension, and the belt should be throwing up over it without touching.

Frequently Asked Questions
Please call us at 605-338-0403 for help with any question.
Return pressure is higher than 450 PSI. If you have wing style couplers, make sure they're screwed down all the way. Check that the Return filter isn't getting plugged. If this doesn't fix the problem, call before adjusting anything on the hydraulic block.
The upper belt should be between 4 - 5.5 seconds per revolution. We generally don't time the lower belt because of the difference in lengths of trailers. Increase the truck idle speed to increase belt speed.
There is a contaminant in the flow control needle valve on the hydraulic block, located on the upper conveyor. Valve is on the top rear, driver-side of the block (titled Flow Control). Loosen jam nut, and turn the valve out until desired speed is reached. Re-tighten jam nut.
Truck Wet Kit: No power to the center prong on the 7-way plugin. The control panel is powered off the ABS or center prong. Check for a blown truck fuse or low voltage from truck batteries.
The Upper Control Panel has a switch that was left on or got bumped.
There is a rock stuck in the throttle body, below the air cleaner. Turn engine off. Usually you can use an air hose to blow it out.
