Frequently Asked Questions

Why does the master warning light come on and then go off?

A transient fault or intermittent sensor issue may cause the master warning to flash on the HX180L. Check the monitor for stored codes and consult the service manual if it persists.

Can I continue working with the amber caution light on?

Yes, but you should investigate as soon as possible. The HX180L's caution indicates a non-critical issue that may worsen over time.

How often should I drain the water separator?

Every 500 hours or when the water-in-fuel light appears on the HX180L. Daily before operation, check the separator if moisture is expected.

What does the swing lock light mean?

The swing lock is engaged on your HX180L, securing the upper structure. Release it before attempting to slew to avoid mechanical damage.

Why is the glow plug light still on after starting?

If the glow plug light remains on after engine start on the HX180L, the glow relay may be stuck or controller fault. Have the system checked by a dealer.

Is it safe to operate with the check engine light on?

The HX180L can run, but continued operation may cause reduced power or increased emissions. Have the engine diagnosed promptly.
