Test the Drive Brakes

Proper brake action is essential to safe machine
operation. The drive brake function should operate
smoothly, free of hesitation, jerking and unusual
noise. Hydrostatic brakes and hydraulically-
released individual wheel brakes can appear to
operate normally when they are actually not fully
operational.

2 Start the engine from the platform controls.
3 Move the engine idle control switch to
foot switch activated high idle (rabbit and
foot switch symbol), then lower the boom into
the stowed position.
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.
5 Bring the machine to top drive speed before
reaching the test line. Release the drive joystick
when your reference point on the machine
crosses the test line.

your machine reference point. Refer to
