5.01 Coolant Filter Cleaning Procedure
Periodic cleaning of the coolant fi lter ensures maximum coolant fl ow effi ciency. Poor coolant fl ow causes inef-
fi cient torch parts cooling with consequent faster consumable wear.
Clean the coolant fi lter as follows:
1. Disconnect system from maintenance input power.
2. Unscrew and remove the fi lter bowl by hand. Be sure to keep the O-ring.
3. Remove and clean the fi lter. Re-install the bowl, tightening it by hand. Be sure the O-ring is in place.
4. Turn the system ON and check for leaks.
