Cooling System Safety

•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
•
Do not operate the machine without the covers
in place.
•
Keep your fingers, hands and clothing clear of
rotating fan and drive belt.
•
Shut off the engine and remove the key before
performing maintenance.
Checking the Cooling
System
Service Interval: Before each use or daily
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol anti freeze.
Check the level of the coolant in the expansion tank at
the beginning of each day before starting the engine.
The capacity of the cooling system is 7.5 L (6 US qt).
1. Check the level of the coolant in the expansion
tank (Figure 43). The coolant level should be
between the marks on the side of the tank.
2. If coolant level is low, remove the expansion tank
cap and replenish the system. Do not overfill.
3. Install the expansion-tank cap.
1. Expansion tank

Cleaning the Radiator

Service Interval: Before each use or daily Clean the
radiator more frequently in extremely
dusty and dirty conditions.
Keep the radiator clean to prevent the engine from
overheating.
Note:
If the attachment or engine shuts off due to
overheating, first check the radiator for an excessive
buildup of debris.
1. Open the hood and secure the prop rod.
2. Loosen the flange nut securing the clean-out
cover to the underside of the rear frame
44). Rotate the cover to the side to expose the
clean-out hole in the frame.
1. Clean-out cover
3. Working from the fan side of the radiator,
blow out debris with low-pressure (50 psi)
compressed air (do not use water). Repeat this
