Frequently Asked Questions
How do I clear the DPF regeneration light on my Merlo P65.14?
Drive the telehandler at a moderate load for 20-30 minutes, or perform a stationary regeneration via the control panel following the manual's instructions.
What should I do if the master warning light comes on while operating?
Stop the Merlo P65.14 immediately, shift to neutral, and note the code on the display. Refer to the fault code guide in the operator's manual.
Why is the brake system light red even after releasing the parking brake?
This indicates a fault in the brake circuit. Check the brake fluid reservoir and inspect for leaks. If the light persists, contact a Merlo dealer.
Can I continue driving with the reduced power light on?
Yes, but at reduced speed and load. This limp mode protects the engine. Have the Merlo P65.14 diagnosed as soon as possible.
How often should I replace the air filter on the Merlo P65.14?
Every 500 hours or when the air filter indicator light appears. In dusty conditions, check more frequently.
What does the overload light mean and how do I reset it?
It means the lift capacity is exceeded. Reduce load immediately. The light resets automatically when the load is safe.
