Filling
Procedure
Remove the coolant tank.
Clean the inside of the coolant tank before you replace the coolant.
Pour a little tap water into the tank, and then shake the tank to the left and right. Dispose of any dirty
water. Repeat this step until the water does not become dirty when you shake the tank.
Refer to the appropriate safety data sheet (SDS) for the chemical substances used in the additives and
the safety related to those substances.
Contact your authorized Roland DG Corporation dealer to purchase additives.
CAUTION
Be sure to put the specified additive in the coolant tank.
Additives are effective in reducing coolant deterioration and raising the milling
efficiency in order to maintain product performance. Also, if additives are not
used, the coolant may generate an unpleasant odor.
Steps to Perform Following Installation
Open the bottom cover.
Pull out the coolant tank.
Make the coolant.
The coolant should have a water-to-additive ratio of
95:5. Use the included measuring cup for measuring.
The capacity of the coolant tank is approximately 3
L. To fill the tank, use 2850 mL of water and 150 mL
of additive.
After you combine the water and additive, there is
no need to mix the substances together.
