General Sweeping Minimize dust by reducing brush speeds and by sweeping on days with high moisture. Try to keep wind at your side or back. (Refer to figure 1.) For light material, angle the sweeper 30° left or right. Prevent damage to the sweeper by removing large foreign objects. Preferred Wind Directions When Sweeping Figure 1 51-3845, 7/04 OPERATION SECTION OPERATING TIPS If Material Piles in Front of Sweeper • Decrease travel speed • Increase the engine rpm • Make more than 1 pass • Raise the brush to decease the contact area • Increase the sweeper angle If Brush Wears Unevenly • Check for material wrapped around the brush • Clean underneath the hood If Driveline Wears Quickly • Decrease travel speeds • Make more than 1 pass, especially in deep, heavy materials • Avoid ramming piles • Lack of lubrication – lubricate more often 20 Removal/Storage 51-3845, 7/04 Sweeper & Hitch Removal NOTE – Whenever removed, install clevis pins, hitch pins, clips and hardware into the sweeper and hitch for storage. 1. Install stands in storage position and fully lower the attachment lift. 2. Disconnect the drive shaft by pulling back on the locking collar and then pulling the shaft off. 3. Disconnect hydraulic hoses. Disconnect hairpins and remove clevis pins. Slide hitch assembly off the slots on the tractor. 4. Detach the sweeper from the sweeper hitch by moving the shot pins into open position. 5. Lower the hitch to the ground and back out. Brush head not shown OPERATION SECTION REMOVING SWEEPER AND HITCH Lock Open (Out) 51-3845, 7/04 MAINTENANCE SECTION DAILY MAINTENANCE CAUTION – Allow only trained personnel to operate or service this implement. Know and understand all precautions before assembly, service or operation. Also read and understand all safety precautions in the tractor operator’s manual. Lubrication Gearbox Check gearbox lubricant every 25 hours. 1. When oil is cold, remove the top plug (figure 1). Make sure oil is level with the plug hole. 2. If needed, add gear oil meeting SPI GL5 80w-90 classification. Do not exceed a 50/50 mix with synthetic oil. 3. Reinstall the plug. NOTE – You do not have to change gearbox oil. Drive Shaft After every 8 operating hours, lubricate 3 grease points (figure 2) on the drive shaft with multi-purpose grease. Do not over grease universal joints. Bearings All bearings on the sweeper are permanently lubricated for long life and require no lubrication. Drive Chain Lubricate with oil when changing brush sections. Tractor Air Filter Due to dusty conditions, check the tractor air filter often. Further instructions appear in the tractor operator’s manual. Be sure to follow the recommendations for “extreme conditions” as the air filter can be affected by dust and other debris raised by the sweeper. figure 1 figure 2 51-3845, 7/04 MAINTENANCE SECTION DAILY MAINTENANCE/BRUSH REPLACEMENT Daily Maintenance Checks Hardware – Check and tighten all hardware on the sweeper, including factory-installed hardware. Brush Contact – Check brush contact. (See Adjusting Brush Contact Area, page 25.) Brush Replacement Replace sections when worn to 14 in. (356 mm) in diameter. NOTE – Replacing brush sections can be accomplished more easily with the sweeper mounted on the tractor than with it on the ground. 1. Remove the chain guard (figure 1) from the right- hand side of the brush head. 2. Disconnect the drive chain (figure 2) at the master link. Remove the chain from the large sprocket. 3. Loosen 2 set screws on each lock collar located at each end of the brush core (figures 3 and 4). 4. Remove the chain guide plate (figure 5). Figure 2 Drive End Figure 3 Figure 1 Bearing End Figure 4 Figure 5 51-3845, 7/04 MAINTENANCE SECTION BRUSH REPLACEMENT Figure 6 5. Remove the snap ring from the large sprocket (figure 6). 6. Remove the lock hub by removing all set screws and then inserting the screw indicated in figure 7. 7. Remove the sprocket, washer and key from the brush core. 8. Loosen 2 M8 hex nuts that retain the bearing on the bearing end of the core (figure 8). 9. Slide the core to the toward the bearing end to allow additional space on the other side. 10. Remove 3 M8 carriage bolts, lock washers and hex nuts that retain the drive end bearing and flanges (figure 9). 11. Pull the brush core from the brush frame (figure 10). 12. Remove 3 screws to take the retainer plate off the core. 13. Remove old sections. Continued on next page Figure 7 Figure 8 Figure 9 Figure 10 51-3845, 7/04 MAINTENANCE SECTION BRUSH REPLACEMENT 14. Install new sections by doing the following. a. Number the tubes on the core as 1, 2, and 3 (figure 1). b. Slide the first section onto the core with the drive pins (figure 2) on both sides of tube 1. Make sure that the drive pins face up. NOTE – When using 1/2 poly–1/2 wire sections, place a poly section first and last on the core to prevent damage to the hood, driveline and frame. c. Place the second section on the core with the drive pins on both sides of tube 2. Be sure the dr...
