Frequently Asked Questions
What should I do if the Master Warning light comes on?
Immediately stop the New Holland L220 in a safe location and shut off the engine. Check the display for the specific fault and refer to the operator's manual before restarting.
Why is the DPF regeneration light on?
The DPF needs to burn off accumulated soot. Drive the L220 at a higher engine load for 20-30 minutes or perform a stationary regeneration as per the manual.
Can I continue to operate with the Check Engine light on?
No, you should have the L220 diagnosed as soon as possible to prevent further engine damage and comply with emission regulations.
How do I reset the service hour meter light?
The service interval reminder can be reset by a dealer; it is not user-resettable on this model.
My hydraulic light flickers when using the loader— what does that mean?
It indicates low hydraulic fluid or a pressure issue. Check the fluid level and look for leaks before resuming work with the L220.
Is it normal for the glow plug light to stay on a few seconds?
Yes, it preheats the engine. Wait until it turns off before cranking the L220, especially in cold weather.
