7.2.4 Cleaning the Cooling System

NEVER touch or adjust your engraver's water supply while your engraver is still
connected to power.
Your coolant tank should be shielded from ambient dust created during work. If your coolant ever
becomes visibly dirty, discontinue work. The debris in the water will reduce its cooling efficiency,
can heat up itself, and can damage the cooling pipes.
1. Remove the right panel following the instructions above.
2. Check the coolant.
If your coolant remains visibly clean at all times, it is still recommended that you clean the water
tank at least once a year as a precaution, replacing the fluid as you do so.
If the coolant is especially polluted, clean it as follows:
a. Uncap the water tank.
b. Use a baster or fluid extractor to remove
the contaminated coolant.
c. Use a funnel to refill the tank with clean
water and then remove it.
d. Return the engraver to working order.
