How to examine the driving belt:
Examine all the belts, if there is any broken, we should change it immediately. If there are two or more belts to connect two pulleys, all the belts should be changed together.
Only when teh degree of belt tightness is good, the lifetime of the belt will be much longer. If there is not only one belt, the tighter belt of them ought to be checked or adjusted.
How to change the fan belt:
◇Take off the fan cover;
◇Take off the six bolts which fasten the fan and punch, and then take off the whole parts.
Note: Please be careful when take off the fan, to make sure not damage radiator.
◇Undo the tension regulator of belt, take off the old belt, make sure there is no oil stain in pully groove and then install new belt.
◇Install the fan and bolts, adjust the tension degree of fan belt, and then install fan cover.
Air intake system:
The function of gas engine air intake system is: after purification, the fresh air and certified gas fuel mix steadily and then enter into cylinder to meet the requirement of air and gas fuel for gas engine working.

Adopt the world famous JEASON diaphragm type, the structure of pressure maintaining valve is simple and it is easy to adjust, which ensure the reliable air intake pressure for genset.
2. Mixer
Mixer is a important part in the air intake system. It's main function is mix air and gas fuel steadily before entering into cylinder.
3. Air filter
The function of air filter is dedusting, reduce the wear and tear of cylinders and pistons, prolong the engine lifetime.
It's working principle is: air enter into inner chamber through filter air intake port.
Blade revolve when air flow.Then dust will be thrown into filter wall within the centrifugal force and sendimented in the air discharge exit. After that, air will enter into mix through the paper filter core hole.
4. Air intake pipe
Air intake pipe is the cast aluminimum members, 4/6 cylinders engine can be used together for each cylinder. Please note when you install air intake pipe, the mating face of air intake pipe and cylinder cover should be seal. It is not allowed to let any impuritied to enter into air intake pipe, otherwise it will enter into cylinders and cause engine damage.
