Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Blocked radiator fins
  • Faulty thermostat

What to do

On a Solis compact tractor, stop the engine immediately, let it cool, then check the coolant reservoir and clean the radiator screen. If the light persists, inspect the thermostat and water pump.

Low Oil Pressure

Common causes

  • Low oil level
  • Oil pump failure
  • Clogged oil filter

What to do

Check the engine oil level using the dipstick on your Solis tractor. If full but the light remains, do not run the engine; tow to a dealer to inspect the oil pump and filter.

Charging System Failure

Common causes

  • Worn or loose alternator belt
  • Faulty alternator
  • Corroded battery connections

What to do

Inspect the alternator belt tension and condition on your Solis tractor; tighten or replace if necessary. Clean battery terminals and check for voltage at the battery with the engine running.

Check Engine Warning

Common causes

  • Poor fuel quality
  • Faulty oxygen or EGR sensor
  • DPF regeneration issue (if equipped)

What to do

Use a diagnostic tool compatible with Solis to read the fault code. Avoid prolonged operation with the light on; refuel with quality diesel and consider a dealer inspection.

Frequently Asked Questions

Why does the glow plug light stay on longer in cold weather on my Solis tractor?

The glow plug preheating time increases in cold temperatures to ensure proper starting. It is normal for the light to stay on for several seconds below freezing.

Can I drive my Solis tractor with the check engine light on?

It is not recommended. While some faults allow limited operation, continued driving may cause further damage. Have the code diagnosed as soon as possible.

What should I do if the differential lock light stays on?

Ensure the differential lock pedal or switch is fully released. If the light remains, the mechanism may be stuck; drive forward and backward gently to disengage. If it persists, consult your Solis dealer.

How do I reset the service hour meter on a Solis compact tractor?

The service reminder typically resets through the dashboard menu or by holding a reset button. Refer to your Solis operator's manual for the specific procedure, as it varies by model.

What does the PTO light mean and when is it safe to work on implements?

The green PTO light indicates the power take-off is engaged. Always disengage the PTO, wait for it to stop rotating, and remove the key before servicing attachments.
