Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Stop the Solis 20 immediately and allow the engine to cool. Check coolant reservoir and radiator fins for debris. If problem persists, replace the thermostat or have cooling system flushed.
Low Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Shut off the engine and check oil dipstick. Add oil if low; replace oil filter and use recommended viscosity. If light stays on, have oil pressure tested by a dealer.
Charging System Failure
Common causes
- Loose or corroded battery terminals
- Worn alternator belt
- Faulty alternator
What to do
Inspect and clean battery terminals, tighten connections. Check alternator belt tension and replace if worn. If alternator is faulty, replace it to prevent battery drain.
Transmission Overheating (if equipped)
Common causes
- Low transmission fluid
- Overloading
- Faulty cooling fan
What to do
Stop the tractor and let transmission cool. Check fluid level and add if needed. Reduce load and ensure cooling fan is operational.
Frequently Asked Questions
Why is the check engine light on my Solis 20 flashing?
A flashing check engine light indicates a severe misfire or catalyst damage risk; reduce load immediately and seek dealer service.
What does the hydraulic warning light mean on the Solis 20?
The hydraulic warning light alerts you to low hydraulic oil level or a filter blockage; check the sight glass and replace the filter if needed.
How often should I service my Solis 20 based on the hour meter?
Refer to the owner's manual; typical intervals are every 50 hours for engine oil and filter, and every 200 hours for transmission fluid.
