Cooling System Safety

CAUTION
Discharge of hot, pressurized coolant or touching a
hot radiator and surrounding parts can cause severe
burns.
• Do not remove the radiator cap when the engine
is hot. Always allow the engine to cool at least 15
minutes or until the radiator cap is cool enough
to touch without burning your hand before
removing the radiator cap.
• Do not touch the radiator and surrounding parts
that are hot.
DANGER
Swallowing engine coolant can cause poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.

Checking the Cooling System

Service Interval: Before each use or daily
Check level of coolant at the beginning of each day. The
capacity of the system is 8.5 L (9 US qt).
1. Carefully remove the radiator cap.
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and cause
burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Expansion tank
2. Check the coolant level in the radiator. The radiator
should be filled to the top of the filler neck and the
expansion tank filled to the F
3. If the coolant is low, add a 50/50 mixture of water and
ethylene glycol anti freeze. Do not use water only or
alcohol/methanol base coolants.
4. Install the radiator cap and expansion-tank cap.

Cleaning the Cooling System

Service Interval: Before each use or daily—Remove debris
from the engine area, oil cooler, and
radiator.
Clean them more frequently in dirty conditions.
This machine is equipped with a hydraulically driven fan drive
system that automatically (or manually) reverses to reduce oil
cooler/radiator and screen debris build-up. While this feature
can help reduce the time required to clean oil cooler/radiator,
it does not eliminate the need for routine cleaning. Periodic
cleaning and inspection of the radiator/cooler is still required.
1. Unlatch and swing open the rear screen
Note: To remove the screen, lift off the hinge pins.
2. Clean the screen thoroughly of all debris.
