Cooling System
Maintenance
Cleaning the Radiator and the
Screen
Service Interval: Every 200 hours—Inspect the
cooling-system hoses.
Every 1,500 hours—Replace any moving hoses.
Every 1,500 hours—Flush and replace the
cooling-system fluid.
To prevent the engine from overheating, keep the screen and
radiator clean. Check the screen and radiator daily and, if
necessary, clean any debris off these parts. Check and clean
the screen and radiator more frequently in extremely dusty
and dirty conditions.
Note: If the PTO shuts off due to high engine temperature,
first check the radiator and screen for an excessive buildup of
debris. Clean the system before operating the machine. Do
not shut off the engine immediately; allow the engine to cool
by running it without a load.
Clean the radiator as follows:
1. Remove the screen.
2. Working from the fan side of the radiator, blow with
low pressure, 172 kPa (25 psi), compressed air (do not
use water). Repeat this step from the front of the
radiator and again from the fan side.
3. After the radiator is thoroughly cleaned, clean out any
debris that may have collected in the channel at the
radiator base.
4. Clean and install the screen.
