(Picture 7) 4) Detach the bearing’s bolts (2 pc) and socket screws from the bearing. (Picture 8) 5) Remove the end plate located under the bearing by removing the bolts.
Picture 9. Changing the brush rings 7.4. Adjusting the chains The back broom has a chain at right side, which transfers the power between the propeller shaft and the broom roller’s axle. Check chains for tightness after every 50 operating hours. If chains are too loose, they will be needlessly strained. If chains are too tight, they will strain cogwheels and axle’s bearings.
7.5. Removing the back broom from the base machine 1. Lower the back broom down on an even surface on its support legs (picture 12). 2. Adjust the support wheels so that the brush rings don’t touch the ground. 3. Turn off the base machine, apply the parking brake and depressurize the system. 4.

8.7. Adding oil to the angle gearbox The angle gearbox in the middle has oil inside. The oil is checked and changed using the dip stick that is located behind the cover box (picture 16). When the device is horizontal the oil level must be at least level with the minimum level shown on the dip stick.
