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 the
rotating fan and drive belt.

Coolant Specification

The coolant reservoir is filled at the factory with a
50/50 solution of water and ethylene glycol base
extended-life coolant. Check the coolant level before
you first start the engine and daily thereafter; refer to
Checking the Coolant Level (page
The following commercially available coolants or
a manufacturer-specified equivalent meeting the
long-life coolant specification:
Extended-Life Coolant Products
Ford (Motorcraft™)
FCA—Chrysler (Mopar™)
General Motors (AC
Delco™)
Volkswagen
Coolants meeting technical standards ASTM D3306 or
D4985, or SAE J1034, J814, or 1941.
Important:
Do not rely on the color of the coolant to
identify the difference between conventional (IAT) and
extended-life (OAT) coolant types.
Coolant manufacturers may dye extended-life coolant
(OAT) in one of the following colors: red, pink, orange,
yellow, blue, teal, violet, and green.

Note:
When adding coolant to the machine, you will
not damage the cooling system by mixing conventional
(IAT) antifreeze with extended-life (OAT) antifreeze.
However, mixing antifreeze types degrades the long
life/extended life attribute of the OAT formulation.
Important:
The service interval of conventional
(IAT) and extended-life (OAT) blended-coolant
mixture—at any ratio—lasts as long as the coolant
with the shortest service interval: 2 years.

Checking the Coolant Level

Service Interval: Before each use or daily Check the
level of coolant in the radiator and
the expansion tank at the beginning
of each day before starting the
engine.
CAUTION
If the engine has been running, the coolant
may be hot and pressurized. If you open
the radiator cap when the coolant is hot, it
could spray out and severely burn you or
bystanders.
Allow the engine to cool for at least 15
minutes before opening the radiator cap.
Important:
Do not add coolant to an overheated
engine until the engine has fully cooled. Adding
coolant to an overheated engine may crack the
engine block.
1. Position the sprayer on a level surface.
2. Engage the parking brake, shut off the spray
pump, shut off the engine, and remove the key.
3. Carefully remove the radiator cap and the
expansion-tank cap
