Haas 165 alarm: Low lubrication pressure

The lubrication system does not reach the expected pressure or lubrication cycle. It is an alarm from the Lubrication area, and in the catalog it is listed as “Low lubrication pressure”. On the machine you notice it like this: Periodic alarm, Can lock automatic cycle, Risk of damage to guides/spindles.

On the shop floor it almost always comes from one of these causes: Empty tank, Blocked filter or line, Bomba de engrase defectuosa, Faulty pressure sensor. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset only after confirming pressure/correct lubrication cycle. Resetting without fixing the cause first only hides the problem: Haas 165 trips again and, in the meantime, you keep working with the machine in bad shape.

With the machine stopped and in a safe state, start with these checks: Check oil level and grade, Revisar fugas visibles, Run manual lubrication cycle if the procedure allows it. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Haas 165 active, avoid this: Do not continue producing without confirmed lubrication, Do not override pressure sensor. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If pressure does not rise after refilling or there are dry lines/leaks. If you are not sure how far it goes, stop the machine and report it: a repeat alarm always works out cheaper than a crash.

It is critical: there is a real risk of damage to the machine, the tool or a person. Leave the machine stopped, do not keep resetting it to see if it goes away, and call maintenance before producing again. See Haas manual for the installed lubrication system.
