12.1 Coolant level
Maintain coolant level. Low coolant level can cause
foaming and high blade temperatures. Replace
dirty coolant; dirty or weak coolant can clog the
pump, cause crooked cuts, a low cutting rate
and/or permanent blade damage. To fill the tank,
remove the filter cup and pour coolant into the hole
to about 80% of full capacity. Full capacity is 9
liters (2.25 gal). Follow coolant manufacturer’s
instructions for proper use and disposal.
