Test the Drive Brakes
Proper brake action is essential to safe machine
operation. The machine uses drive motor
regenerative braking to stop the machine.
Hydraulically-released individual wheel brakes hold
the machine once it has stopped. The drive motor
regenerative braking should operate smoothly, free
of hesitation and jerking. Hydraulically-released
individual wheel brakes can appear to operate
normally when not fully operational.
Collision hazard. Be sure that the
machine is not in free-wheel or
partial free-wheel configuration.
Refer to B-6,
Confirm the Proper
Brake Configuration .
Note: Select a test area that is firm, level and free
of obstructions.
1 Mark a test line on the ground for reference.
2 Lower the boom into the stowed position.
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 Bring the machine to maximum drive speed
before reaching the test line. Release the drive
joystick when your reference point on the
machine crosses the test line.

hesitation, jerking and unusual noise over the
entire proportionally controlled speed range.
Note: Select a test area that is firm, level and free
of obstructions.
1 Create start and finish lines by marking two lines
on the ground 40 feet / 12.2 m apart.
2 Lower the boom into the stowed position.
3 Choose a point on the machine; i.e., contact
patch of a tire, as a visual reference for use
when crossing the start and finish lines.
4 Bring the machine to maximum drive speed
before reaching the start line. Begin timing
when your reference point on the machine
crosses the start line.
5 Continue at full speed and note the time when
the machine reference point passes over the
finish line. Refer to Section 2,
