Test the Drive Brakes
Genie specifications require that this procedure be
performed quarterly.
Proper brake action is essential to safe machine
operation. The drive brake function should operate
smoothly, free of hesitation, jerking and unusual
noise. Hydraulically-released individual wheel
brakes can appear to operate normally when not
fully operational.
Note: Perform this procedure with the machine on
a firm, level surface that is free of obstructions.
Note: The platform extension deck must be fully
retracted and the platform in the stowed position.
1 Mark a test line on the ground for reference.

out the red Emergency Stop button to the on
position at both the ground and platform

4 Choose a point on the machine; i.e., contact
patch of a tire, as a visual reference for use
when crossing the test line.
