Cleaning Debris From Cooling System

1. Touching hot surfaces can burn skin. The engine, components, and fluids are hot if the engine has been running. Allow the engine to cool before servicing or working near the engine and components.

   Checking, cleaning cooling fins and oil cooler must be performed every 100 hours.

   Park machine safely on a level surface. (See Parking Safely in the SAFETY section.)

2. To avoid damage from overheating, clean all debris from cylinder head cooling fins, oil cooler, and engine area as stated in the machine service intervals.

   • The interval for cleaning debris from the engine compartment area is daily.

   •Remove the cleanout panels and clean all debris from cylinder head cooling fins every 100 hours, or more frequently depending on operating conditions.

   • The interval for removing the cooling shrouds and cleaning debris from complete cooling system is every 500 hours, or more frequently depending on operating conditions.

   After inspection, If all debris cannot be cleaned out after performing 100 Hour Interval, perform the Every 500 Hours interval.
