WARNING
THE OPERATOR SHOULD NOT ATTEMPT TO REPAIR ANY RADIO CONTROLLER. IF ANY PRODUCT
PERFORMANCE OR SAFETY CONCERNS ARE OBSERVED, THE EQUIPMENT SHOULD IMMEDIATELY
BE TAKEN OUT OF SERVICE AND BE REPORTED TO THE SUPERVISOR. DAMAGED AND INOPERABLE
RADIO CONTROLLER EQUIPMENT SHOULD BE RETURNED TO MAGNETEK FOR EVALUATION AND
REPAIR. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS INJURY OR DEATH AND
DAMAGE TO EQUIPMENT.
2.4 PRE-OPERATION TEST
At the start of each work shift, or when a new operator takes control of the crane, operators should do, as
a minimum, the following steps before making lifts with any crane or hoist:
Test all warning devices.
Test all direction and speed controls.
Test the receiver emergency stop.
2.5 TRANSMITTER UNIT
Transmitter switches should never be mechanically blocked ON or OFF. When not in use, the operator
should turn the transmitter OFF. A secure storage space should be provided for the transmitter unit, and
the transmitter unit should always be placed there when not in use. This precaution will help prevent
unauthorized people from operating the material handling equipment.
Spare transmitters should be stored in a secure storage space and only removed from the storage space
after the current transmitter in use has been turned OFF, taken out of the service area and secured.
This manual covers two types of Flex transmitters: the Flex EM and Flex EX. Refer to Section 3.3 for the
differences between these two transmitter types.
