Frequently Asked Questions
Why does the Master Warning light come on intermittently on my L230?
Intermittent activation can be due to a loose sensor connection or a temporary fault. Check the secondary warning light and consult your dealer for diagnostic codes.
Can I operate the L230 with the Hydraulic System light on?
No, continued operation can cause pump damage. Stop and check hydraulic oil level and temperature; if okay, have the system inspected.
What does the Glow Plug light mean in warm weather?
The glow plugs may still cycle for a short time to reduce emissions. Wait for the light to turn off before starting your L230.
How often should the Fuel Filter light be reset on my L230?
The light resets automatically after replacing the filter. It alerts when water is detected or filter is restricted; replace per the service schedule.
Is it safe to drive with the Brake System light on?
No, it indicates a potential brake fault. Stop the machine and check brake fluid level and parking brake switch on your L230.
What should I do if the Check Engine light stays on after starting?
The engine can be operated lightly, but you should schedule a dealer visit to read fault codes and prevent damage to your L230's emission system.
