BF12M1015CP can be widely applied into the fields of Generator sets, Construction Machinery and so on.
1.1 Safety and Warning
Shut down the engine before carrying out repair and maintenance, and ensure the engine should not be accidentlly and suddenly started.
Stop the engine while filling fuel and coolant. Abide by the related industrial safety regulations and rules while running the engine in an enclosed space or underground
1.2 Maintenance and Care
Sound care and maintenance practices will ensure that the engine continues to meet the requirements placed on it. Recommended service internals must be observed and service and maintenance work carried out conscientiously. Special care should be taken under abnormally demanding operating conditions

3.1 Commissioning
3.1.1 Filling in Engine Oil
As a rule, the engines are delivered without oil filling. Fill in lube oil through the oil filler neck (arrow).
3.1.2 Filling Oil Bath Air Cleaner With Engine Oil
Fill engine oil into bowl 1 of oil bath air cleaner (if fitted) up to the arrow mark.
3.1.3 Filling the Fuel Tank
Use only commercial-grade diesel fuel. For fuel quality grade.see 4.2
Use summer- or winter-grade fuel, depending on the ambient temperature
3.1.4 Filling/Bleeding Cooling System
Connect coolant inlet 1 and coolant outlet 2 to external coolant tank.
Fill in coolant into cooling system
Start engine and run up to normal cperating temperature until thermostat opens (line 2 warms up)
Check coolant level in external cooling system, top up coolant if necessary.
3.1.5 Other Preparations
Check battery and battery cable connections.
Trial run
- 10 min. Upon completing the preparations, run the engine for a short trial run of about 10 minutes under low load.
During and after trial run
- Check the engine for leaks
After the engine has been stopped
- Check oil level and top up if necessary, see 6.1.2
- Retense V-belts, see 6.5
Breaking-in
During the breaking-in phase, it is recommended to check the oil level twice a day. After the breaking-in phase, checking once a day will be sufficient.
3.2 Starting
3.2.1 Electric Starting
Before starting, make sure that nobody is standing in the immediate vicinty of the engine or its driven machine.
After repare work, Check if all removed guards are put back in place and all tools are taken away from the engine.
When starting with flame-type heater plugs, do not use any other additional starting aids (e.g. Injection with start pilot)
Do not acutate the starter for more than 20 seconds at a time. If the engine does not start, wait one minute before repeating the attempt.
If the engine does not start after two attempts, trace the cause with the aid of the Diagnosis Chart (see 7.1)
3.3 Monitoring Systems
3.3.1 Engine Oil Pressure
Oil Pressure Pilot Lamp
The oil pressure pilot lamp lights up with operating voltage applied and engine shut off.
The oil pressure pilot lamp must go out when the engine is running.
Oil Pressure Gauge
The pointer of the oil pressure gauge must not indicate the minimum oil pressure (see 9.1).
3.3.2 Coolant Temperature
The pointer of the coolant temperature indicator should remain in the green sector and enter the yellow-green sector only in exceptional cases. If the pointer enters the orange secor, the engine is overheating. Turn it off and establish the cause from the Diagnosis Chart (see 7.1).
3.3.3 Coolant Level
Lamp of coolant level indicator lights up (contact via float switch/level sensor when min. Cooolant level has been reached):
Turn engine off and establish cause from the Diagnosis Chart (see 7.1)
Fuctional check of coolant level:
insert key into position 1 or 2 (Float switch or leel sensor) Pilot lamp lights up for about 2 seconds.
- Coolant level is ok: lamp goes out.
- Coolant levei is not ok: lamp does not go out.
3.3.4 Lube Oil Level
Lamp of lube oil level indicator lights up (contact via float switch/level sensor when min.lube oil has been reached.)
Turn engine off and establish cause from the Diagnosis Chart(see 7.1)
Funtional check of lube oil level:
insert key into position 1 or 2 (Float switch or leel sensor) Pilot lamp lights up for about 2 seconds.
- Lube oil level is ok: lamp goes out.
- Lube oil levei is not ok: lamp does not go out
