Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump malfunction
- Blocked oil filter
What to do
Immediately shut off the engine, check the oil level, and inspect for leaks or filter blockage. Refill or replace components as needed before restarting the KX018-4.
Coolant Temperature
Common causes
- Low coolant level
- Faulty thermostat
- Blocked radiator
What to do
Shut down the engine and allow it to cool. Check coolant level, inspect for leaks, and clear any debris from the radiator of your KX018-4.
Overload / Capacity
Common causes
- Lifting a load heavier than rated capacity

Frequently Asked Questions
What should I do if the DPF regeneration light comes on?
Follow the regeneration procedure outlined in the KX018-4’s manual to prevent DPF clogging and reduced engine performance.
Can I keep working if the air filter warning light is on?
No, a clogged air filter can cause poor engine performance and damage; clean or replace the filter promptly.
Why does the hydraulic oil light come on after long use?
Extended operation can raise hydraulic oil temperature or cause fluid loss; let the machine cool and check the fluid level.
What does it mean if the swing lock light is illuminated?
This means the upper structure is locked and cannot rotate; disengage the swing lock if rotation is required.
Is it safe to operate with the master caution light on?
While not immediately dangerous, you should identify and address the underlying issue as soon as possible to avoid bigger problems.
