NOTE
An audible alarm will sound and a warning light will illuminate when a gear is selected with the
parking brake applied. The alarm will stop when neutral is selected.
Under normal conditions, when engaged, the parking brake electronically disconnects the
transmission drive; this prevents the machine from being driven with the parking brake on.

8.
Push down hard on the brake pedal and select forward drive (WP 0004).

reduce the engine speed. Failure to follow this warning may result in injury or death to personnel.
CAUTION
Do not perform this test for longer than 20 seconds. Failure to follow this caution will result in
damage to equipment.
9.
Release the brake pedal (WP 0004).
10. If the machine has not moved, use the accelerator pedal to increase the engine speed to 1,500 rpm (WP 0004). The
machine should not move.
11. Reduce the engine speed to idle and set the forward/reverse lever to Neutral (WP 0004).
12. Release the parking brake test switch (Figure 13, Item 1).
13. Lower the work tools to the ground and stop the engine (WP 0004).
