Section 5
Symptoms:
Low coolant flow, no alarm. Low coolant flow, the
pump cavitates (cavitation sounds like heavy grit in the pump
head, or a suction sound) or is otherwise noisy.
Possible Cause:
The coolant does not return to the coolant tank
fast enough. The coolant level in the coolant tank is low.
Chips build up in the auger trough [1], and the coolant return
drain [2] on the enclosure pan. This slows the coolant from
returning to the coolant tank.
Corrective Action:
Remove all chips from the the auger trough [1], and the coolant
return drain [2].

to complete these tasks:
Remove chips from the coolant tank. Excessive chips in the coolant tank reduce the amount of coolant the tank can
store. Watch the video

head, or a suction sound) or is otherwise noisy.
Possible Cause:
The pressure relief spring in the pump head is
damaged.
Corrective Action:
1. Remove the TSC pump from the tank.
2. Remove the pressure relief plugs.
3. Inspect the spring and valve pin. Replace the spring if it is
