CLEANING THE TRACK GROUPS Under working conditions with excessive material build up on the crawler components, cleaning of the crawlers is very important to prevent damage. Material build up on guide wheels, drive sprockets and tracks can lead to over tensioning of the tracks, resulting in severe damage to these components. If there is danger of frost, the tracks must also be cleaned. NOTICE Use a suitable cleaning device for removing dirt, mud and debris from the tracks, rollers, guide wheels and sprockets. 239 WARNING
