burn hazard. Purge hot plastic from the system and cool the barrel before
disconnecting water cooling fittings.
Use compressed air safely.
CAUTION
Do not get water on unpainted surfaces such as ball screws, barrel, feed
screw, belt tensioner, etc. as they will rust, causing damage to the machine.
Never run the system without water cooling. Serious damage to the
machine will result.
CAUTION
1.
Turn off water connections and disconnect supply line at the manifold.
Disconnect return line and place in a bucket or other suitable container.

until no more water comes out of the return line.
