Check Wheel Coolant Levels
With a lack of wheel coolant, the brakes can generate enough heat to burn the tire bead. A burning bead produces gases inside the tire that can explode, endangering personnel within 460 meters (1500 ft).
Position each tractor and each scraper wheel so the coolant fill plug is level with the center of the axle.Remove the plug. Maintain the wheel coolant level to the bottom of the plug opening with an 80% water and 20% ethylene glycol-type antifreeze solution. Clean and install the plug.(35)ROPS Bolts
