●Keep hands and clothing (especially a
tie, a scarf or a muffler) away from the
fans and belts.
Failure to do so may cause the hands
or clothing to be caught, resulting in
serious injury.

Do not loosen the coolant inlet cap or
coolant reservoir cap while the engine
and radiator are hot. (The coolant inlet
cap is located under the engine cover.)
High temperature steam or coolant

cap, coolant reservoir cap, or inter-
cooler reservoir cap while the engine
and radiator are hot. High tempera-
ture steam or coolant could spray out.
