Checking the Radiator
Screen and Radiator for
Debris
Service Interval: Before each use or daily

radiator screen and radiator clean. Check the radiator
screen and radiator for buildup of grass, dust, and
debris, and if necessary, clean any debris off these
parts.
Cleaning the Radiator
Screen and Radiator
Service Interval: Every 200 hours—Inspect the
cooling-system hoses.
Every 1,500 hours or 2 years, whichever comes
first—Replace any moving hoses.
Every 1,500 hours—Flush and replace the
cooling-system fluid.
Note:
If the PTO shuts off due to high engine
temperature, first check the radiator screen and
radiator 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 radiator 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 you have thoroughly cleaned the radiator,
clean out any debris that may have collected in
the channel at the radiator base.
4. Clean the radiator screen and install it onto the
machine.
