SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 5 Install Scrapers Install the scraper(s) in the gutter. On single-gutter installations, position the scraper in the end opposite the power unit and as close to the corner wheel as possible. If two scrapers are used, position one in each gutter and at opposite ends of the gutter. One should be at the corner wheel and the other at the dump point near the power unit. The blades are designed to remove an adequate amount of manure without overloading the system. (Part failures due to overloading the system are not considered “defective” under warranty) The scraper blade is designed to move manure to a dump point. If the scraper does not move freely though the pit area and more clearance is needed, cut an equal amount off each end of the scraper. Leave it long enough to clean the pit floor. Install the Stainless Steel Cable Use only 5/16” -7x19 stainless steel cable in the system. Hog Slat part # 617276 Feed the cable though the power unit and corner wheels. Attach the cable to the cable bracket on the scraper blade leaving 3-4” from the point where you want the blade to stop. Pull excess cable between the blade and the power unit though the power unit. Thread the cable through the scraper system as shown in Figure 1. No cable clamps or connectors can pass through the corner wheels or power unit drive pulley. Cable Adjustment Remove the cable clamps and the cable from the scraper. Pull the cable snug and lap the cable ends one on top of the other on the cable bracket and install two cable clamps (do not tighten the clamps). Use a come-a-long or suitable cable-tightening device to tighten cables (do not over tighten the cableapproximately 200# tension is all that is necessary on the cable). Tighten the cable clamps. Turn the power unit by hand to pull the blade up to the discharge point. Go over to opposite pit and to the opposite end of the building and position the second scraper at the point at which the blade will stop in reverse. Cut a piece of cable approximately 12” long to lay over top of continuous cable going across the scraper. Attach to cable scraper with clamps and tighten. To figure required cable lengths, add the combined lengths of all pits, plus the return side of a single or odd pit if used, plus the total length of all crossovers, plus a minimum of 5 ft. to lace the power unit. It is best to overestimate the lengths as spliced cable cannot be used to go through the power unit or corner wheels. After the cable is connected to the scrapers and run through the power unit, test the unit to see if it will pull the scrapers.
