Conditions
Tools needed:
Phillips screwdriver
3/8” drive socket wrench with 7/16” socket
1. Remove all connectors and the line cord from the back of the shaker.
2. Lift the front of the shaker and rest it on its back. Remember that the
weight of the shaker is 138 pounds (62.7kg).
Caution The shaker is not stable when lying on its back. A second person
may be necessary to support the shaker while in this position. ▲
3. Remove the bottom cabinet cover (2 Phillips screws).
4. Loosen but do not remove, the two 7/16” screws located in the slotted
holes adjacent to the shaker drive motor. Refer to Figure 4-1.
5. Loosen but do not remove, the 7/16” screw adjacent to the drive
motor, which is not in a slotted hole. The drive motor pivots around
this screw. Loosening all three screws allows internal springs to apply
proper tension to the v-belt.
