Before you start
- Never use the maintenance handle to transfer the load with the power connected. Disconnect both power sources before manually operating the switch.
Procedure
- If equipped with a maintenance handle, remove the handle from its storage location inside the enclosure.
- Insert the maintenance handle or a tool into the hole in the shaft on the left side of the operator.
- Move the maintenance handle (or tool) up or down to manually operate the transfer switch; it should operate smoothly without binding.
- Return the transfer switch to the Normal position.
- Remove the maintenance handle and return it to the storage location.
