22 HOPPER DUST FILTER 3. Remove the dust filter from the hopper. REPLACING THE HOPPER DUST FILTER Shake the dust filter at the end of every shift and before removing the filter from the machine. Inspect and clean the filter after every 100 hours of operation. Replace damaged dust filters. NOTE: Clean the filter more often if used in extremely dusty conditions. FOR SAFETY: Before leaving or servicing machine, stop on level surface, set parking brake, and turn off machine. 1. Unlatch and open the hopper cover. Support the hopper cover open with the hopper cover prop rod. 4. Clean or discard the dust filter element. Refer to CLEANING THE DUST FILTER. 5. Clean dust and debris from the dust filter tray. 2. Remove the dust filter cover. NOTE: Do not operate filter shaker or raise hopper with dust filter cover removed. Shaker motor damage can occur. 6. Reinstall the dust filter. 7. Reinstall the dust filter cover. 8. Close the hopper cover. 12

23 HOPPER DUST FILTER MEASUREMENT Check 1/8 thick shaker spacer for wear, replace as necessary. With hopper dust filter cover removed and cyclone cover latches locked, check filter seal measurement for proper height. Top of seal should measure 6.35mm (.25 ) above filter cover mounting base, as shown below. This will allow proper sealing of filter with filter cover installed. Rear side of filter box assembly FILTER SEAL HEIGHT ADJUSTMENT *Safety Note* Cyclone filter box assembly is heavy, assistance recommended for removal. Remove filter box assembly from hopper. With cyclone cover in place and latched, mark seal height measurement at 4 places; RF--LF--RR--and LR areas of filter box M10 screw locations for shaker mounting tray are shown below. Loosen shaker tray mounting bolts and adjust tray to obtain proper seal filter height measurement and tighten as necessary. Reassemble filter box, using new seals where needed.
