4-6 Model SHKE8000 Series Shakers
Warning Remove and lock-out electrical power when working on or near
the heating element connectors. Allow sufficient time for the heating
elements to cool before reaching into that area.
A manual reset circuit breaker is located
between the heating element electrical
connectors on the top of the heater
assembly (Figure 4-9). The heating
element is attached to the duct wall
behind the grille. To access the heating
element and this circuit breaker, remove
the eight Phillips screws securing the
right side grille to the chamber wall
(Figure 4-8).
When the shaker is in place and level, with the
platform installed, turn the unit on and set the
RPM to 300. Kneeling in front of the shaker,
lightly touch the lower left and right corners of
the cabinet. If one side seems to vibrate more
then the other, raise or lower the leveling foot
using the 3/4" open end wrench supplied in the
parts bag. Continue this "fine tuning" until the
vibrations are lowered as far as possible. Ensure locking nuts are secured
when complete.
Caution Do not extend leveling feet more than 1/4 inch from the bottom
of the unit. When the unit is leveled and tuned, with the leveling feet
locked in place, the adjustment and locking nuts should be no further
apart than 1/4 inch.

Each platform is adjusted to fit the unit with which it is shipped. In the
instance of replacement or additional platforms, adjustments may be
required. To check for undue platform vibration noise during operation,
see the steps following.
