Clean the radiator screen (wire mesh).
After the tractor has been operated in dusty condi-
tions, check the screen daily and clean if necessary.
Clean the radiator cores by applying water spray or
compressed air so as to form a right angle with the
radiator cores, moving water application in parallel.
Note:
When cleaning the radiator cores with pressurized
water be sure to apply it at a right angle to the
cores. Slanted applications might deform their
cooling fins.
