Track Brake
The track brake is normally applied and is hydraulically released to allow
the tracks to rotate.
If the track motor and hydraulic hoses are replaced, the track brake line
must be bled.
On the HMI, navigate to the Chassis Settings screen. Press the Parking
Brake button to disengage the parking brake.
Loosen the track brake hose fitting (smallest hose) until fluid is expelled.
Tighten track brake fitting.
Enable the parking brake on the HMI.

Maintenance
Track Tension
Correct track tension is important to wear of the tracks. If the
tracks are too tight or too loose, it will wear rapidly.
To check track tension:
Place a straight edge across both track idlers. Measure the
amount of sag from the straight edge to the track. Correct track
tension is approximately 1.25" (32mm).
Due to the track on the HMI side of the machine being covered
with a guard, the correct track measurement from the power
pack side track can be used to set the HMI side track.
Measure the distance from the track weldment to the bottom of
the track and use that distance to set the tension of the HMI side
track.
To adjust track tension:
Remove track adjustment cover.
Use a grease gun and add grease to the track grease zerk to
increase track tension.
To relieve track tension, turn the cartridge fitting enough to allow
grease to exit. Removing the grease zerk will not allow grease
to exit.
