damage to the engine. The engine oil level can 
only  be  checked  when  the  engine  is  placed 
horizontally  and  closed.  If  the  engine  is  hot, 
close the engine and check the engine oil level 
5  minutes  later.  Check  it  immediately  if  the 
engine is cooled. 

1) 

Insert  the  oil  measuring  rod  and  clean  it 
with a piece of clean and fiber-free cloth. 

2) 

Insert the oil measuring rod into the bottom. 

3) 

Pull out the oil measuring rod and read the 
value of engine oil level. 

4) 

The  engine  oil  level  shall  always  be 
between MIN and MAX! 

Fill up to the maximum liquid level if necessary. 

1.8  Replacement  of  Engine 
Oil and Filter 

!

Do not operate on running 

engines! No smoking and open fires! 
Be careful when contacting with high 
temperature engine oil. Danger of 
scalding!

 

!

When operating on the oil system, 

pay attention to the surface cleaning. 
Carefully clean all areas involved. Blow 
wet parts with compressed air.

 

!

Please observe the safety 

regulations for engine oil and relevant 
local regulations. Dispose of spilled 
engine oil and filter elements as 
required. Waste oil cannot penetrate 
into the ground. 

!

Test run shall be carried out after 

each operation. At the same time, pay 
attention to the sealing and lubrication 

oil pressure, and then check the 
engine oil level.

 

It  is  available  in  the  first  50  hours,  and  the 
engine oil and filter shall be replaced every 500 
hours. (If the ambient temperature continues to 

be  below  -10

.  (14

F)  or  the  temperature  of 

engine oil is below 60

  (84

F), or the sulphur 

content  in  the  diesel  fuel  is  0.5  -  1%,  the  oil 
change period is reduced by a half; if the engine 
oil  does  not  reach  the  replacement  interval 
period within a year, the oil shall be replaced at 
least once a year.) 

!

Danger of burn, be careful of 

high-temperature engine parts and oil, 
contacting with high temperature 
engine oil and/or engine parts will 
cause severe burns.

 

!

Perform the function after engine 

warm up to normal operation 
temperature. 

Replacement of engine oil 

!

After the filter element is replaced, 

be sure to keep the engine idling at a 
low speed for at least 3-5 minutes, so 
that the engine has been lubricated 
before being put into operation.
