2 Introduction Thank you for your purchase of a Henke All Hydraulic Wing for your John Deere G Series motor grader. The bolt-up/bolt-up attaching structure design of this wing allows greater rotation of the main grader blade than other designs, which improves snow moving capability. The All Hydraulic Wing consists of four main subassemblies: 1. Wing Post and Attachment Assemblies 2. Moldboard and Pushbeam Assemblies 3. Rear Attachment Assembly (either: Elevating Rear, Fixed Rear, Manually Elevating Rear, or Rear Ripper Attachment) 4. Hydraulic Hoses and Fittings Before beginning your installation, please check that all of the appropriate ship-loose parts and hardware listed in Table 1 was received. In the unlikely event that any parts are missing, please contact Henke Manufacturing Corporation for replacements. The cutting path, defined as the distance perpendicular to the motion of the vehicle, of the snow wing is approximately 80% of the moldboard length. Therefore, an AHW-12 would have a cutting path of almost 10 feet. The parts lists for the AHW JD G snow wing are listed in Tables 2 thru 12 (if applicable). These lists are important and should be referred to when ordering replacement parts from your local dealer or Henke Manufacturing Corporation. The parts diagrams for the snow wing are shown in Figures 1 thru 7. This Product Manual should be read in its entirety before using your Henke AHW JD G snow wing to minimize mounting problems. For customer service, replacement parts, or answers to questions about your Henke plow, please call Henke Manufacturing at (913) AHW_66BH_42BH_JD_GP_T3_GRADE_PRO_EFF_ALL_ _01_024.DOCX Page 2 of 49

6 In Season Maintenance Snow removal equipment must be cared for and maintained regularly. Daily or pre-route inspection and maintenance are necessary. Failure to do so may affect efficiency and safety. A visual inspection must be carried out after every 8 hours of operation. Look for damaged components, bends, cracked welds or hydraulic leaks. REPAIR IMMEDIATELY! It is recommended to re-torque all bolts after the first 8 hours of use and to regularly check for loosened or missing fasteners. Replace any damaged or missing fasteners immediately. Because of the environment in which snow equipment is expected to operate, hydraulic lines, fasteners, wearable or replaceable items and warning decals may become damaged by snow, ice and road debris. These items must be inspected daily and replaced if necessary to avoid equipment damage or personal injury. Lubrication of moving parts is of the utmost importance. Exposure to snow, ice, salt and road debris will wash away lubrication quickly and it may be necessary to inspect and reapply lubrication more than once a day. AHW_66BH_42BH_JD_GP_T3_GRADE_PRO_EFF_ALL_ _01_024.DOCX Page 6 of 49

7 End of Season Maintenance GROUND ENGAGING COMPONENTS CUTTING EDGES & GUARDS Replace any broken cutting edges, unevenly or excessively worn cutting edges, and broken or worn wear guards. RUNNING GEAR Replace broken, worn, or missing running gear shoes, and any damaged adjuster leg components. Grease internal threads and sliding members (it s best to disassemble and grease directly; zerks aren t as effective at greasing these areas). HARDWARE Replace missing or broken bolts. Proper torque is important! Use grade 8 plow bolts for steel cutting edges. HYDRAULICS HOSES Plug or cap any QC fittings or any open hose ends. Inspect hoses for any leaks or potential leaks. Secure hoses with hose clamps. CYLINDERS Check for leaks, and any chrome rod dents or scratches. Apply a light coat of oil or grease on exposed rod surfaces. FRAME AND MOLDBOARD JOINTS Check pins, bushings, and pivot bolts for wear. Make sure all keepers are in place. Make sure shear bolts and pins are same as original equipment (usually grade 2). Some drivers don t like replacing shear pins and will install grade 8 replacements to avoid replacing during a storm. These items are designed to shear to protect the driver and the equipment. CHECK WELDMENTS FOR CRACKS. REPLACE WORN OR BROKEN PARTS FOUND BY ABOVE INSPECTIONS. The installation hardware provided for the All Hydraulic Wing is listed below. If any hardware is missing please contact Henke Manufacturing Corporation. All installation hardware is yellow zinc plated for long-term corrosion resistance.
