ROUTINE MAINTENANCE
RADIATOR
WARNING: Never open cap on a hot radiator�
Prior to cold weather, be sure cooling system has a proper amount of antifreeze. Use a quality brand of permanent-type
ethylene glycol antifreeze which contains a rust inhibitor and lubricant. Use a 50/50 ethylene glycol antifreeze and clean
water. Articially softened water should not be used. During extremely cold conditions a higher concentrate of antifreeze will
be needed. Leave antifreeze in the cooling system during hot weather operation.
WARNING: Check coolant level only, when engine is stopped and radiator cap is cool enough to touch with your
hand�
CLEAN RADIATOR
At the end of each work period the radiator should be cleaned. Remove all branches and chips from around housing. Use
compressed air to clean cores and screens.
TO ACCESS THE SCREEN FOR CLEANING
Open the radiator access panel (see photo) and blow this area clean of debris.
NOTE: The optional reversing fan is designed for occasional purging of
airborne debris from the radiator screen. The reversing fan is not intended for
cleaning the radiator cores. It is the operators responsibility to clean the radiator
cores with compressed air to maintain maximum cooling efciency. The
frequency of cleaning the radiator core is determined by the working conditions.
Under normal working conditions the radiator core should be cleaned at least
once a week.
NOTE: Do not purge fan while engine is under load. Immediate temperature
rise will occur. During the purging process there is no air ow through the
radiator cores while the fan is switching directions. If the temperature
remains high after purging screen, the radiator cores will need cleaning.
Continuing to try to clean the core with reversing fan will result in engine
overheating.
