High engine coolant temperature.

Engine shutdown in 10 seconds for having a high-temperature engine coolant. 

Engine Air Filter The air filter switch needs to be connected.

The switch is facing high restrictions.

Hydraulic Filter The hydraulic filter switch is not attached and faces restrictions. 

Advanced Control System (ACS)

This Bobcat warning light symbol is for signaling any issues with the Advanced Hands Control system. It usually stays on but alerts the driver with beeping noises.

If you notice 3 consecutive beeps regarding the AHC, this means there’s a malfunction in the AHC system. 

It’s better to avoid any DIY strategies to solve the error in this case. As soon as you notice the beeping noises, you must contact a professional to identify and fix the AHC issue. 

Advanced Control System

Attachment Control Device (ACD)

The ACD symbol refers to the Attachment Control Device. It stays lit to notify the electrically controlled attachment is present.

But if you see the ACD light flashing 3 times, it indicates an error in the Attachment control device. You need to check the Bobcat control instructions to fix this issue.   

General Warning

The 90-degree square box with an explanation sign is the general warning light symbol in a Bobcat machine. This symbol is a precaution sign for the engine’s operational defects. 

General Warning

If one or more engines stop working, this sign lights up with a red light. The same happens when the hydraulic function of the vehicle malfunctions. It’ll beep 3 times to warn you about the error. 

However, the general warning sign beeping 3 times also means the engine is at high speed. If the speed is extremely high, the warning sign flashes continuously. It indicates the engine will shut down within 10 seconds. 

Whenever you notice the engine speed is high, you can control it by using the engine speed controller on the right side of the operator’s seat. Simply, pull it backward to decrease the engine speed RPM. 

Fuel Level

Next, you’ll see a symbol like a gas cylinder which refers to the fuel level symbol. It signals when you have low fuel in your Bobcat vehicle.

Fuel Level

When you notice this warning light is beeping 3 times, it means 2 things. Either there’s a system fault in the fuel level sender system or the fuel is extremely low.

In this case, you need to add Grade No. 2 fuel at 40℉. Make sure you add the fuel only in the free movement area. Don’t keep anything flammable nearby. If the fuel filter is faulty, replace it immediately to prevent accidents. 

Glow Plugs

The glow plug warning light symbol is the one with a light bulb image. When it’s on, it means the glow plugs are working. You’ll also see a GLOXX written on the hour meter during this operation.

Glow Plugs

The XX will show you how much time the glow plugs will stay activated. But if you see the light flashing thrice, it means there’s an error with the glow plugs.

System Voltage

The battery-like symbol you notice on the dashboard is the system voltage warning light. This warning symbol lets you know if the voltage is high or low. And it works by beeping 3 times to send you a signal that the voltage is at fault. 

As soon as the system voltage warning light signals you, check the alternator if it’s defective. It’ll result in low charge issues so you need to fix it immediately. Again over-charging can be unhealthy for your vehicle. You need to find the reason too.   

Seat Belt

The seat belt warning light is to remind you to put on the seat belt while operating the vehicle. You’ll see the light ON for 45 seconds until you put on the seat belt. It’s actually to keep you safe while driving around the vehicle.

So, it’s best to wear your seat belt as soon as you’re about to fire the engine.

Engine Oil Pressure

Now, you’ll notice another light bulb-shaped icon on the dashboard with a drop drawn inside it. There are also two arrows pointing at the bulb from the two sides. This symbol warns you about the engine oil pressure state in your Bobcat tractor. 

Engine Oil Pressure Symbol

If you hear 3 beeps, this means the engine oil pressure is low. It can also be that the engine oil pressure sender is out of range. This happens when the wire is not connected to the sender or the wire is short-circuited due to high voltage. 

Finally, the warning light starts continuously flashing. This is a signal that the engine oil pressure is extremely low and the engine is about to shut off in 10 seconds. 

Hydrostatic Charge Pressure

Now, we’ll talk about the hydrostatic charge pressure which looks like a horizontally kept egg with 2 stars inside it. The entrances on both sides have arrows pointing upward. It indicates 3 types of warning signals – system error, low hydrostatic charge pressure, and shutdown.

With beeping 3x, the hydrostatic charge pressure light refers to a defect in the hydrostatic charge pressure. It can also mean that the charge is below its limits.

Again, when the symbol constantly keeps beeping, this means the engine will shut down in 10 seconds because of low hydrostatic charge pressure. 

Engine Coolant Temperature

The next symbol on your dashboard is an empty bulb and a thermometer beside the bulb. It alerts you whenever the engine coolant level or temperature is higher than required. 

If 3 beeps are coming from this warning light, you’ll understand the engine coolant temperature sender is out of range. Similarly, it can also mean the temperature is high.

Now when you see the light is constantly beeping, this means the temperature is so high that the engine prepares to get shut at 10 seconds. So, you have to maintain the temperature anywhere between 32-70℉.  

Hydraulic Oil Temperature

Well, the hydraulic oil bobcat warning light symbol also has a thermometer like the engine coolant temperature symbol. But it has a drop inside a ring beside that thermometer. This symbol helps you to get alerted about the temperature of hydraulic oil. 

When the hydraulic oil temperature sender doesn’t work or the temperature is high, it beeps 3 times. It keeps continuously beeping for high temperatures and signals you the engine will turn off in 10 seconds.  

Engine Air Filter

The symbol with an arrow getting inside a light bulb is the engine air filter sign. If the air filter switch is not connected, you’ll see this light ON and having 3 beeps. But if you see the light flashing with 3 beeps, note that the air filter is facing high restrictions.  

Hydraulic Filter

Finally, you’ll notice the hydraulic filter symbol showcasing a drop inside a ring. This warning sign beeps 3 times and stays lit when the hydraulic filter switch isn’t connected. But it flashes with 3 beeps when the hydraulic filter has high restrictions.
