Mazak 260/261 alarm: Guide/head lubrication alarm

Mazak detects lubrication problem in slideway or head. It is an alarm from the Lubrication area, and in the catalog it is listed as “Guide/head lubrication alarm”. On the machine you notice it like this: Lubrication alarm, Risk for guides/head, May repeat cycle after cycle.

On the shop floor it almost always comes from one of these causes: Nivel bajo, Lubrication pump, Clogged line, Pressure/level sensor. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after confirming lubrication. Resetting without fixing the cause first only hides the problem: Mazak 260/261 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 the level and that the oil is correct, Look for leaks, Do not produce without confirmed lubrication. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Mazak 260/261 active, avoid this: Do not bypass safety devices, Do not manipulate energized electrical cabinet, Do not continue producing if the alarm reappears. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If pressure/flow is not recovered. 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. Guidance reference. Always confirm the full text in the exact machine/control manual.
