International Road Federation Video VH-109 Operator Daily Maintenance of Crawler Tractors Visit the International Road Federation at http://www.irfnews.org/ - Noncommercial Use Only - Published with Permission - General methods and procedures for operator daily maintenance on crawler tractors are demonstrated and explained. An operator goes through a maintenance checklist divided into four groups: prestart (a walkaround check for damaged parts or fluid leaks and a check of the engine and air filter system); warm-up (monitoring engine and dozer blade performance, checking brakes and steering); operating check (listening for unusual noises, reading gauges); and shutdown (proper parking, refueling, lubricating and cleaning).
