The Sany excavator instrument cluster provides critical warnings and status indicators to ensure safe and efficient operation. Designed for durability, it uses intuitive color-coded lights to alert the operator to system conditions, from routine checks to urgent failures.
Sany excavator Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected on your Sany excavator, requiring immediate engine shutdown to prevent damage. | Stop the engine immediately, consult the dashboard display for the fault code, and contact Sany service. | |
| Master Caution | AMBER | A non-critical issue is present in your Sany excavator, such as a low fluid level or a sensor malfunction. | Check the central display for the specific warning and address as needed; continue operation with caution. | |
| Check Engine (MIL) | AMBER | The engine control unit has logged a fault, often related to emissions or fuel system on this Sany excavator. | Have the engine diagnosed by a Sany technician; continued operation may reduce power. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe level, risking severe engine damage on your Sany excavator. | Stop the engine immediately and check oil level; if full, call for service. | |
| Battery / Charging | RED | The alternator is not charging the battery properly, which may lead to electrical failure on the Sany excavator. | Check alternator belt and connections; if light persists, replace alternator. | |
| Coolant Temperature | RED | Engine coolant is overheating, often due to low coolant or a clogged radiator in your Sany excavator. | Stop the engine, let it cool, then check coolant level and radiator for debris. | |
| Brake System | RED | A brake system fault has been detected, such as low brake fluid or worn pads on the Sany excavator. | Check brake fluid level and inspect brakes; do not operate until resolved. | |
| Parking Brake | RED | The parking brake is engaged or a fault in the brake circuit is present on your Sany excavator. | Release the parking brake before moving; if light stays on, inspect switch or brake system. | |
| Low Fuel | AMBER | Fuel level is low, and your Sany excavator may run out soon, causing air in the fuel system. | Refuel as soon as possible to avoid engine stalling and priming issues. | |
| Hydraulic System | RED | A hydraulic system fault, such as low oil level or high temperature, threatens operation on your Sany excavator. | Stop the machine, check hydraulic oil level and for leaks; consult service manual. | |
| Glow Plug / Preheat | AMBER | The glow plugs are heating for cold start; if flashing, a glow plug circuit fault exists on this Sany excavator. | Wait for light to go out before starting; if flashing, have glow plugs checked. | |
| Fasten Seat Belt | RED | The operator's seat belt is not fastened; this is a safety requirement on your Sany excavator. | Fasten the seat belt immediately to silence the alarm. | |
| Air Filter | AMBER | Engine air filter is clogged, reducing airflow and power on your Sany excavator. | Replace or clean the air filter according to the maintenance schedule. | |
| Water in Fuel | AMBER | Water has accumulated in the fuel filter/water separator, which can damage the injection system on your Sany excavator. | Drain the water from the fuel separator as described in the operator's manual. | |
| Work Lights | GREEN | The work lights are turned on, illuminating the area around your Sany excavator. | No action needed; turn off when not in use to save battery. | |
| High Beam | BLUE | The high beam headlights are active for better visibility on your Sany excavator. | Dim to low beam when approaching other vehicles or worksites. | |
| Swing / Slew Lock | AMBER | The swing lock is engaged to prevent superstructure rotation during transport on your Sany excavator. | Disengage swing lock before operating; if light stays on, check lock mechanism. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator clogged with debris
- Faulty cooling fan
What to do
Stop the engine and allow it to cool. Check coolant reservoir and add specified coolant if low. Clean radiator fins with compressed air. If persistent, inspect fan belt and thermostat; contact Sany dealer.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Immediately shut down the engine. Check oil level with dipstick; add SAE 15W-40 if low. If level is normal, do not restart – call for Sany service to inspect pump and filter.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic leak
- Contaminated hydraulic fluid
What to do
Stop the excavator. Check hydraulic oil level at sight glass; top up with Sany recommended fluid. Inspect hoses for leaks. If light remains, have the system tested for internal leaks or pump issues.
Charging System Malfunction
Common causes
- Loose alternator belt
- Faulty alternator
- Battery terminal corrosion
What to do
Check alternator belt tension and tighten if loose. Clean battery terminals with a wire brush. If light stays on, test alternator output voltage; replace if defective.
Brake System Warning
Common causes
- Low brake fluid level
- Worn brake pads
- Brake line leak
What to do
Check brake fluid reservoir and add DOT 4 fluid if low. Inspect brake pads for wear; replace if thickness below 3 mm. Look for fluid leaks around calipers and lines; repair as needed.
Frequently Asked Questions
Why does my Sany excavator's master warning light come on intermittently?
Intermittent master warning often indicates a sensor fault or loose connection. Check the display for fault codes; common causes include coolant temperature sensor or hydraulic pressure sensor anomalies. Schedule a diagnostic with Sany service.
What should I do if the hydraulic warning light flashes amber while digging?
Flashing amber hydraulic light suggests high oil temperature or low fluid. Stop digging, let the hydraulic system cool at idle, check oil level and ensure the hydraulic oil cooler is clean. If persistent, avoid heavy loads until serviced.
Can I continue working with the check engine light on in my Sany excavator?
You can continue for a short time, but reduced power or increased emissions may occur. Avoid heavy digging; have the fault code read by a technician as soon as possible to prevent engine damage.
How do I drain water from the fuel system on a Sany excavator?
Locate the fuel/water separator on the engine; it has a drain valve at the bottom. Place a container under it, open the valve, and drain until clean fuel appears. Close the valve and prime the system if needed. Refer to your model's manual.
What does the glow plug light mean if it stays on after starting?
If the glow plug light remains on after the engine starts, it indicates a fault in the glow plug circuit, such as a blown fuse or failed relay. Have the system inspected to ensure reliable cold starts.
Why does my Sany excavator show a low fuel warning even after refueling?
This may be due to a faulty fuel level sensor or a stuck float in the tank. First, ensure the tank is actually full. If it persists, the sensor may need calibration or replacement – contact Sany dealer.
