M08 starts the optional coolant supply and M09 stops it. Use M34/M35 to start and stop the optional Programmable Coolant (P-Cool). Use M88/M89 to start and stop the optional Through-Spindle Coolant.

note: The control checks the coolant level only at the start of a program, so a low coolant condition will not stop a running program.
caution: Do not use straight or “neat” mineral cutting oils. They cause damage to rubber components in the machine.

M08 turns on the optional coolant supply and M09 turns it off. For High Pressure Coolant, see M88/M89.

You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
