• Avoid contact with any components containingcoolant. At or near operating temperature, the enginecoolant is hot and under pressure and could causesevere burns.
• Check the coolant level only after the radiator cap iscool enough to touch. Remove the radiator cap slowlyto relieve pressure.
• Do not allow your skin to come in contact with hot oilor components containing hot oil. At or near operatingtemperature, engine and hydraulic oil is hot and canbe under pressure.
• Always wear safety glasses and protective gloveswhen handling batteries. Keep sparks or open flamesaway!
