Changing Coolant

The Model G0669X coolant reservoir holds approximately 7 gallons (26 liters) of fluid. We rec- ommend changing this fluid every three months or sooner if it develops an unpleasant odor.

4.Drain the reservoir, then clean any debris and sludge from the reservoir and pump.

5.Replace the pump and access panel.

6.Remove the reservoir screen on the mill base, fill the reservoir with non-flammable water- based coolant, then replace the screen.

Always use non-flammable water-based coolant to avoid explosions when the fluid comes in contact with hot metal chips from the milling operation. For best results, always follow the coolant manufacturer's recom- mendations for coolant/water ratios.
