3 INSPECTION AND MAINTENANCE Periodic preventive maintenance should be practiced. Inspect tarp system often for proper operation. Periodically inspect front and rear arms (and spiral springs) for loose or worn parts and replace as needed. Clean telescoping components for smooth operation.! CAUTION: Some lubricants attract dust, avoid using on telescoping components. Always use genuine Agri-Cover, Inc. replacement parts if repairs are needed. Periodically check the tightness of mounting bolts and electrical connections, remove any dirt or corrosion that may have accumulated on the electrical connections. The worm gear is lubricated with 5 ounces of Mobil SHC 630 lubricant and sealed for life. Periodically grease zerk fittings and lubricate chain. Remove plastic plug to access chain inside gearbox. Grease zerk Lubricate chain (80W SAE gear oil) 3
