changing caterpiller controls?

i am using a caterpiller 315L excavator and i can't figure out how to change out of SAE controls

1. the operator's manual should be behind the seat. 2. contact your local cat dealer, service manager. 3. contact my local cat dealer, Peterson Tractor 3710 Regional Pkwy Santa Rosa, CA PH: 707-576-1616 FAX: 707-576-0741 Toll Free: 1-800-464-1558 Can't recall service manager (think it's Steve)
