DANGER
Any problems with the service brakes or the parking brake
found while conducting the daily inspection should be
corrected immediately. Failure to do so could result in injury or
death.
Activate the transmission using the transmission control
lever (D). As soon as the machine starts to move, apply the
service brake pedal. The machine should stop immediately.
Apply the parking brake by toggling the parking brake switch
(E) forward. The red light in the upper part of the parking brake
switch should illuminate. The machine should not be able to be
driven with the parking brake in the forward / on position.
