Decal says: ! CAUTION To prevent damage to cab, set hitch lift inks to maximum length for iinitial clearance check of implements-such as roll over plows, etc. To maintain maximum clean air circulation, keep exhaust pipe extension in place, service air filter often and keep doors closed. Avoid steep slopes and other conditions that might cause the tractor to roll over as this cab does not contain roll over protection. Keep windows clean and mirror adjusted for maximum visibility.
