Genie specifications require that this procedure be
performed quarterly.
A properly functioning level sensor (SCON) is
essential to safe machine operation. The ECM at
the ground controls (TCON) monitors the position
and angle of the machine using the signal from the
level sensor. The level sensor signal is used to
control the maximum working height of the primary
and secondary booms.
Note: A digital level will be required to perform this
procedure.
Note: A kit is available through Genie Product
Support (Genie part number 58351GT). This kit
includes a digital level with a magnetic base and
cable harnesses.
Note: A properly calibrated digital level is essential
to proper machine calibration. Refer to the
manufactures calibration information.
Note: Use the following chart to identify the
