Be sure to add Long Life Coolant /Antifreeze (LLC) to cooling fresh water.
In cold seasons, the LLC is especially important.
Without LLC, cooling performance will decrease due to scale and rust in the
cooling water line. Without LLC, cooling water will freeze and expand, breaking
various parts.
IF YOU OPERATE YOUR EOUIMENT AT TEMPERATURES BELOW
THE LIMITS SHOWN, CONSULT YOUR DEALER FOR SPECIAL
