| Low Fuel | AMBER | This amber light warns that the MT 732's fuel level is low, risking engine stall if not refueled soon. | Refuel as soon as possible to avoid air entering the fuel system. | |
| Hydraulic System | RED | On the MT 732, this red light indicates low hydraulic system pressure or a critical hydraulic fault. | Stop machine operation, lower the boom and attachments, and inspect hydraulic fluid level and hoses. | |
| Reduced Power (Limp Mode) | AMBER | This amber light on the MT 732 means the engine control unit has limited power to protect the drivetrain. | Complete current task at reduced speed and schedule service immediately. | |
| Hydraulic Oil | AMBER | This amber light on the MT 732 warns of low hydraulic oil level or high temperature, affecting boom operation. | Check hydraulic oil level and top up if needed; allow system to cool before resuming work. | |
| Air Filter | AMBER | On the MT 732, this light signals that the engine air filter is restricted, reducing engine performance. | Replace the air filter element at the next scheduled service. | |
| Service / Hour Meter | AMBER | This amber light on the MT 732 indicates that scheduled maintenance is due based on engine hours. | Refer to the operator's manual for the required service tasks and perform them soon. | |
| Work Lights | GREEN | This green light on the MT 732 confirms that the work lights are turned on for improved visibility. | No action needed; ensure lights do not blind other operators. | |
| Beacon / Rotating Light | GREEN | When lit green on the MT 732, the rotating beacon is active to warn personnel of machine movement. | No action needed; keep beacon on whenever the machine is in operation. | |
| Swing / Slew Lock | AMBER | On the MT 732, this amber light indicates the swing lock is engaged, preventing upper structure rotation. | Disengage the swing lock before slewing; avoid driving with lock engaged. | |
| Differential Lock | AMBER | This amber light on the MT 732 confirms the differential lock is engaged for improved traction in slippery conditions. | Disengage when on solid ground to prevent drivetrain binding. | |
| Overload / Capacity | RED | On the MT 732, this red light and alarm warn that the load exceeds safe capacity, risking tip-over. | Immediately lower the load and reposition; never exceed rated capacity. | |
| Low Oil Level | RED | This red light on the MT 732 indicates the engine oil level is below the safe minimum. | Stop the engine and add oil of the correct grade to the proper level. | |
| Brake Fluid Level | RED | On the MT 732, this red light warns of low brake fluid level, which can cause brake failure. | Stop the machine and check brake fluid reservoir; top up and inspect for leaks. | |
| Door Open | AMBER | This amber light on the MT 732 indicates the cab door is not fully closed, posing an operator safety risk. | Close the door securely before operating the machine. |

Most Important Warning Lights
Overload Condition
Common causes
- Lifting load beyond rated capacity
- Load shift during transport
- Incorrect attachment use
What to do
On the MT 732, immediately lower the load to the ground and reposition to reduce leverage. Never exceed the load chart specified for your attachment and boom angle.
Low Hydraulic Oil
Common causes
- Hydraulic leak in hoses or cylinders
- Insufficient oil during service
- Overheating causing oil expansion loss
What to do
On the MT 732, stop the machine and inspect for visible leaks. Top up with recommended oil to the correct level, and repair any leaks before resuming operation.
Engine Overheating
Common causes
- Clogged radiator or debris
- Low coolant level
- Faulty thermostat or water pump
What to do
On the MT 732, stop the engine and let it cool. Clean the radiator fins, check coolant level, and inspect belts. If recurring, service the cooling system.
Master Warning (Critical Stop)
Common causes
- Engine shutdown due to low oil pressure
- Transmission failure
- Brake system failure
What to do
On the MT 732, stop the machine immediately and note the fault code. Tow the machine to a service area; do not restart until the root cause is diagnosed and repaired.
Low Oil Level Alarm
Common causes
- Oil consumption due to engine wear
- Oil leak from seals or drain plug
- Over-extended service interval
What to do
On the MT 732, stop the engine and check dipstick. Add oil of the correct viscosity (e.g., 15W-40) and inspect for leaks. Schedule an oil change if needed.
Frequently Asked Questions
Why does the Master Warning light come on immediately after starting the MT 732?
On the MT 732, if the Master Warning light stays on after start, it indicates a system fault. Check the multifunction display for a diagnostic code and consult the operation manual. Common causes include low oil pressure or brake system faults.
Can I continue working with the DPF regeneration light flashing on my MT 732?
No, a flashing DPF light on the MT 732 means regeneration cannot complete, which can lead to filter blockage. Park the machine in a safe place away from combustibles and initiate a stationary regeneration if available.
What should I do if the Overload light and alarm activate while lifting on the MT 732?
Immediately lower the load and retract the boom. On the MT 732, the overload warning means the lift capacity has been exceeded. Reposition the load or use a lighter attachment to avoid tip-over.
How often should I check the hydraulic oil level on the MT 732?
Check the hydraulic oil level daily before operation using the sight glass on the tank. On the MT 732, low hydraulic oil can cause erratic boom movement and trigger the hydraulic warning light.
Why does the transmission temperature light come on after extended use of the MT 732?
The transmission temperature light on the MT 732 typically activates when the transmission oil overheats due to heavy loads or continuous high-speed operation. Reduce load and allow the machine to idle with the transmission in neutral to cool down.
What does the Swing Lock light indicate on the MT 732?
The Swing Lock light on the MT 732 illuminates when the upper structure is locked from rotating. This is meant for transport or when working in a fixed orientation. Release the lock before slewing to avoid damage.
