Reset the pitch of the blade regularly to maintain proper blade pitch using one of the following methods:
Before starting work
During a dozing cycleBefore Starting Work
Before starting work, complete the following steps to reset the pitch of the blade:
Select Grade Control mode, Grade Protection mode, or Rough Grade Control mode using the control keypad.
Depress the service brake to prepare to release the park brake.
Release the park brake in order to release the lock which had previously prevented movement of the blade.
Take the implement lockout off to ensure that the hydraulic system can operate.
