DISASSEMBLY OR REPLACING OF SLICER PLATE AND SLICER IMPELLER
1. Remove Slicer retainer (3 bolts).
2. Use a ball-peen hammer to tap onto (3 blade) rotary slicer impeller. Tap in a counterclockwise direction
(thread is right hand).
3.
Remove “disk-shaped” slicer plate. May have to pry with screwdriver.
4. Once slicer plate is removed, shims will be visible on threaded shaft.
5. Slicer parts can now be cleaned and reassembled or replaced.
6. If discarding all shims, you must use new shims from shim kit.
7. Place (Qty:2) .01 inch shims onto threaded shaft, making certain to align keyway of stock with shaft.
8. Place new or cleaned slicer plate onto threaded shaft, making sure shims stay in place along keyway.
9. Place new or cleaned rotary (3 blade) slicer impeller onto threaded shaft, turning (Clockwise).
10. Rotate onto shaft with hands until snug. Use ball-peen hammer to lock onto shaft.
11. IMPORTANT: USING FEELER GAUGES, CHECK DISTANCE BETWEEN SLICER PLATE AND
SLICER IMPELLER. DISTANCE TOLERANCE (.008-.012 INCHES).
12. If tolerance is satisfactory, go to step 13. If tolerance is beyond or under range, go back to step 7.
13. Place new or cleaned slicer retainer onto volute bottom.
14. Make sure the impeller turns freely by hand after reassembly. Some drag will be present due to the
shaft seals. There should not be any binding or tight spots when turning the slicer impeller.
START KIT REPLACEMENT “C” MODEL
1. Place pump in upright position.
2. Loosen cord cap retaining bolts (1). Keen recommends that a rag or towel be wrapped around the joint

bolts and lift off cord cap.

8. Clean mating surfaces and inspect O-Ring for cuts or damage (replace if necessary). Reinstall cord
cap.
9. Check power cord at plug with ohm meter for shorts to ground.
