Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Blocked radiator fins
- Faulty thermostat
What to do
Stop the Solis 24 immediately and let the engine cool. Check coolant level in the overflow tank; top off with 50/50 mix if low. Clean radiator debris with compressed air.
Low Oil Pressure
Common causes
- Low oil level
- Clogged oil filter
- Worn oil pump
What to do
Stop the engine at once. Check the dipstick; add 10W-30 diesel oil to the full mark. If pressure does not return, replace the oil filter and have the oil pump inspected.
Charging System Failure
Common causes
- Loose or broken alternator belt
- Corroded battery terminals
- Faulty alternator
What to do
Check belt tension; tighten or replace if loose. Clean battery terminals with a wire brush. If light remains, have the alternator load-tested at a Solis dealer.
Fuel System Water
Common causes
- Water-contaminated diesel
- Sitting idle with partial tank
- Failed tank seal
What to do
Open the drain valve on the fuel filter/water separator bowl until clean diesel flows. Replace fuel filter if repeated. Always store tractor with full tank.
Frequently Asked Questions
Can I operate the Solis 24 while the Glow Plug light is on?
No, wait for the Glow Plug light to go out before cranking the engine; otherwise, cold-start performance will be poor and the engine may not start.
What should I do if the Master Warning light comes on and I'm in the middle of mowing?
Stop the mower operation immediately and turn off the engine. Check the instrument cluster for other warnings; common causes on the Solis 24 include low oil pressure or high coolant temperature.
Why is my PTO light staying on even after disengaging the lever?
The PTO switch may be stuck or the clutch linkage is not fully returning. Check the lever movement and ensure the PTO is off; if light persists, inspect the switch at the control panel.
How often should I drain the water separator on the Solis 24?
Drain the water separator every 50 hours or whenever the Water in Fuel light appears. In humid climates, check weekly during regular use.
The battery light came on while using work lights; is this normal?
No, the battery light indicates the alternator is not charging. Turn off work lights to reduce load and head to a service area; a faulty alternator or belt is common on the Solis 24.
Does the Solis 24 have a seatbelt light?
No, the Solis 24 tractor does not feature a seatbelt warning light; however, it is recommended to always wear the seatbelt when operating with a rollover protective structure (ROPS).
