Handling and Service of Engine
Coolant
WARNING! The following safety messages
address a potential Fire Hazard:
• Keep heat, flames and cigarettes away from
coolant.
• Clean coolant spills immediately.
• Stop the engine before replacing the
coolant.
• Wait until the engine is cool to the touch to
replace the coolant.
WARNING! The following safety messages
address a potential Burn Hazard:
• Relieve internal pressure by slowly rotating
the radiator cap during removal.
• Make sure the radiator cap is closed
properly after replenishment of the coolant.
• Never check or add coolant with the radiator
cap removed. Always check and add in the
reserve tank.
• When filling the radiator, do not overfill, as
this may cause the coolant to gush from the
cooling system during machine operation.
WARNING! Exposure Hazard. Avoid skin
contact with coolant.
NOTICE: Always use clean, fresh potable water
when mixing with coolant. Contact us or our sales
service agency for recommendations when using
water other than clean, fresh potable water.
Place the machine on a flat, level surface in the
TRAVEL position to check coolant level.
Do not start the engine until the cooling system is
completely filled with coolant.
Prevent contaminants from entering the coolant or
cooling system.
Check the ratio of the coolant frequently using a
coolant tester. The mixing proportion of coolant
varies with outside air temperature. See “Clean
Engine Cooling System” on page 5-44.
A low coolant level may cause overheating and
corrosion attributed to aeration.
Handling and Service of Gearcase
Oil
WARNING! The following safety messages
address a potential Fire Hazard:
• Keep heat, flames and cigarettes away from
gearcase oil.
• Clean gearcase oil spills immediately.
• Stop the engine before replacing gearcase
oil.
• Wait until the gearcase is cool to the touch
to replace the oil.
WARNING! Exposure Hazard. Avoid skin
contact with the oil.
NOTICE: Always keep gearcase oil at the FULL
level.
For oil type and usage specifications, see
“LUBRICATING OIL” on page 5-10.
Secure gearcase fill, drain and inspection plugs
after inspection and oil replacement. Use seal
tape on the threads to prevent leaks.
