1. Each time you start the diesel engine, must idle (3 ~ 5) minutes, after the normal operation of the
diesel engine parts, before running high-speed operation. Do not allow cold suddenly increase the
throttle, otherwise it will damage the corresponding parts, accelerate the damage to the diesel engine
moving parts (supercharger, etc.), thus shortening the service life of the diesel engine.
2. Strictly according to the nameplate on the calibration power and speed for the correct package,
prohibit over-speed, overload or long-term operation under low load, low speed. It is forbidden to use
the diesel engine unattended.
3. When the diesel engine is working, the temperature of the supercharger, exhaust pipe, muffler,
radiator, etc. is high, so special attention should be paid not to touch the running parts (flywheel, starter
shaft, pulley, etc.) to prevent injury, the fuel tank (diesel) should pay attention to fire prevention, and
the exhaust port should not face flammable materials to avoid danger.
4. Regularly check the tightness of the fastening bolts of the diesel engine connection, and tighten them
in time when they become loose.
5. Pay attention to the oil pressure and cooling water status of the diesel engine in time during
operation to prevent malfunction.
6. It is strictly forbidden to stop the engine suddenly at high speed and under large load, and stop it
after idling for (3-5) minutes. Otherwise, it will damage the zero part (supercharger, etc.) and other
moving parts, thus shortening the service life of the diesel engine.
⊙Maintenance：
1. The air filter should be cleaned and maintained in time, and should be cleaned and maintained daily
in harsh environment.
2. Replace the lubricating oil regularly according to the specification, and clean the diesel engine filter
and oil filter screen regularly.
⊙If you purchase a diesel engine with after-treatment device, please note the following to avoid
unnecessary damage to you.
If non-compliant diesel fuel is used, the following failures and risks may result.
(1) Injector carbon accumulation, gumming, deterioration of engine performance, resulting in higher
fuel consumption and frequent DPF regeneration.
(2) After-treatment poisoning failure, leading to frequent regeneration.
(3) DPF regeneration, the internal temperature is too high, leading to DPF cracking, burning melt and
other damage, which may lead to fire in serious cases.
If non-compliant oils are used, the following failures and risks may result.
