MAINTENANCE
Waste disposer troubles usually involve plumbing. A preventative maintenance program is advisable to keep waste line
stoppage and disposer repair at a mininum. Any sewer problem occurring shortly after your disposer has begun
operation cannot be caused by the new machine. It will be the result of connecting to either an inadequate waste line,
or to one that has not been properly cleared before use. On the other hand, if waste line clogging occurs after the
disposer has been running trouble-free for a year or more, this indicates probable need for servicing.
The slurry leaving a new disposer contains no discernible solids, so there is nothing to clog the waste line. In regular
use, however, wearing of the working parts is to be expected. As the gradual wear occurs, the solid particles passing
through the wider gaps in the shatter mechanism will grow increasingly larger, until waste line stoppage may result.
See Figures.
MONTHLY WEAR CHECK
NOTE: The following should be performed every two weeks if waste is of a highly abrasive consistency.
1. Shut OFF branch circuit power, or emergency disconnect on control panel when disposer has completed its
clean out cycle.
2. Loosen stainless steel clamps on neoprene connector sleeve.
3. Twist neoprene sleeve loose and remove.
4. On “S” and “G” Series, loosen Quick-Release body clamps and lift off aluminum lid.
5. Remove any foreign objects (rubber bands, metal, wood, plastics, etc.) from waste chamber.
6. Check free movement of rotor.
7. The two points of probable wear are the leading edges of the impact bars and the spacing between the outer
edges of the rotor and the inner diameter of the sizing ring teeth (Figure 1, Page 13). When one end of each
impact bar is worn rounded, as shown in Figure 2, Page 13, they need to be reversed (if disposer is wired to an
automatic reversing control).
A. Loosen four hex socket head cap Allen screws to release the bars. Should it be necessary, use liquid wrench
or a mixture of oil and kerosene to help loosen the screws.
