Drive Brake
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.
Perform this procedure with the machine on a firm level surface that is free of obstructions, with the
platform extension deck fully retracted and the platform in the stowed position.

crossing the test line.
Bring the machine to top drive speed before reaching the test line. Release the function enable
switch or the joystick when your reference point on the machine crosses the test line.
Measure the distance between the test line and your machine reference point.
