The Solis 26 HST compact tractor uses a clear instrument cluster to keep you informed of machine status. Warning lights are color-coded for quick assessment of potential issues.
Solis 26 HST Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red light illuminates when the Solis 26 HST detects a serious problem that demands immediate engine shutdown. | Stop the engine safely and consult the operator's manual for the underlying issue. | |
| Master Caution | AMBER | The amber caution lamp alerts you to a non-critical fault that should be addressed soon to avoid a breakdown on your Solis 26 HST. | Check the cluster for additional warning lights and schedule service as needed. | |
| Check Engine (MIL) | AMBER | This light indicates the engine management system has detected a fault affecting performance or emissions on the Solis 26 HST. | Reduce load and have the engine diagnosed by a dealer. | |
| Engine Oil Pressure | RED | Low oil pressure in the engine of your Solis 26 HST can cause severe damage if not addressed immediately. | Stop the engine and check oil level; if okay, contact service. | |
| Battery / Charging | RED | The battery charging system on the Solis 26 HST is not functioning correctly, risking a stalled machine. | Check alternator belt and battery connections; seek repair if light stays on. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits on your Solis 26 HST, which can cause overheating. | Stop the engine and allow it to cool; check coolant level and radiator for blockages. | |
| Transmission Temperature | AMBER | The hydrostatic transmission fluid is too hot on the Solis 26 HST; continued operation may damage the HST. | Reduce load and let transmission cool; check fluid level. | |
| Parking Brake | RED | This red light shows the parking brake is engaged on the Solis 26 HST; it must be released before driving. | Release the parking brake fully before moving. | |
| Glow Plug / Preheat | AMBER | The glow plugs are heating to aid cold starting on the Solis 26 HST; wait for the light to go out before cranking. | Turn the key to the preheat position and wait until the light extinguishes. | |
| PTO Engaged | AMBER | The power take-off (PTO) is engaged on your Solis 26 HST; it can rotate implements and pose a safety hazard. | Disengage PTO when not in use or before leaving the seat. | |
| Differential Lock | AMBER | The differential lock is active on the Solis 26 HST, providing better traction but limiting steering. | Disengage differential lock for normal steering in tight turns. | |
| Low Fuel | AMBER | The fuel level in your Solis 26 HST is low; refuel soon to avoid running out during operation. | Add diesel fuel to the tank. | |
| High Beam | BLUE | The high-beam headlights are on for enhanced visibility on the Solis 26 HST. | Dim your lights when approaching other vehicles. | |
| Work Lights | GREEN | The rear work lights are illuminated on the Solis 26 HST for increased visibility in low-light work areas. | Turn off when not needed to save battery. | |
| Hydraulic System | AMBER | The hydraulic system pressure or fluid level is low on the Solis 26 HST, affecting lift and steering. | Check hydraulic fluid level and inspect for leaks. |

Most Important Warning Lights
Engine Stalled or Won't Start
Common causes
- Low fuel
- Faulty glow plugs
- Safety interlock not engaged
What to do
Ensure the PTO is disengaged, parking brake is set, and seat switch is depressed. Check fuel level and glow plug operation for cold starts.
Engine Overheating
Common causes
- Low coolant
- Radiator blocked
- Broken fan belt
What to do
Stop the engine and let it cool. Check coolant level, clean radiator debris, and inspect the fan belt tension.
Loss of Hydraulic Power
Common causes
- Low hydraulic oil
- Clogged filter
- Leak in hoses
What to do
Check hydraulic oil level and top up if low. Replace the filter and inspect hoses for visible leaks.
HST Transmission Slipping
Common causes
- Low transmission fluid
- Worn drive belt (if applicable)
- Overload
What to do
Check transmission fluid level with engine running and warm. Reduce load and avoid high-speed operation if overheating.
Battery Not Charging
Common causes
- Loose alternator belt
- Faulty alternator
- Corroded battery terminals
What to do
Inspect alternator belt tension, clean battery terminals, and test charging voltage. Replace alternator if necessary.
Frequently Asked Questions
What does the red master warning light mean on my Solis 26 HST?
It indicates a critical fault that could damage the tractor. Stop the engine immediately and consult the manual or dealer.
Why is the check engine light on after a few hours of operation?
This could be due to a faulty sensor or emission issue. Reduce load and have the engine scanned by a dealer for diagnostic codes.
How do I release the parking brake on the Solis 26 HST?
Pull the parking brake release handle or push the button, depending on your model. Ensure the brake indicator light turns off.
Why does the transmission temperature light flash when mowing thick grass?
The HST is overheating due to high load. Reduce ground speed, take lighter cuts, and allow the transmission to cool.
What should I do if the glow plug light stays on for a long time?
If it stays on longer than 10 seconds, the glow plug relay or plugs may be faulty. Have them tested before the next cold start.
Can I drive with the differential lock light on?
Yes, but only on soft surfaces and in a straight line. Disengage for normal steering to avoid driveline damage.
