Okuma 4806/4807 alarm: Lubrication problem/low level

Okuma warns of a lubrication tank or low oil level in axles. It is an alarm from the Lubrication area, and in the catalog it is listed as “Lubrication problem/low level”. On the machine you notice it like this: Warning or stop due to lubrication, Risk for guides/axles, It can be repeated periodically.

On the shop floor it almost always comes from one of these causes: Nivel bajo, Tanque de drenaje lleno, Pump or sensor, Blocked line. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset after reestablishing lubrication system. Resetting without fixing the cause first only hides the problem: Okuma 4806/4807 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: Comprobar niveles, Revisar fugas, 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 Okuma 4806/4807 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 level/pressure is not recovered or there is a leak. 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.
