Test the Drive Brakes
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
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 they
are actually not fully operational.
1 Mark a test line on the ground for reference.
2 Start the engine from platform controls.
3 Choose a point on the machine; i.e., contact
patch of a tire, as a visual reference for use
when crossing the test line.
4 Slowly move the joystick in the direction
indicated by the blue arrow on the control panel
until the machine begins to move, then return
the joystick to the center position.
Result: The machine should move in the
direction that the blue arrow points on the
control panel, then come to an abrupt stop.
