Air Filter

The air filter catridge  is  made  of      

paper. The air filter is consisted of filter       
cartridge assembly,  dust boot,  casing    
and casing cover.

The dust exhausting valve should    

be placed downward to exhaust the     
dust.

Check and clean the outer filter 

 

 

 

 

cartridge of air filter every 8,000km 

 

 

 

 

(4,000km in extremely dusty areas)

.  The     

method is as follows:

1.

Take out the filter cartridge and put it on a         

plain plate and pat it.  Put  a  light  into  the         
filter to check for wear or hole, as well as to          
check the washer, replace it if there is       
something abnormal

.

2.

Using the dry compressed air of 0.5MPa      

to  blow off the accumulated dust from the       
inside toward the circumference of the     
circle.

 Replace the cartridge immedi-    

ately if any of the following situations      
appeared:
a)The outer cartridge has damaged or     

been cleaned more than 5 hours.

b) After 48000km.

The safety cartridge can not be     

cleaned. If the outer cartridge has dam-      
aged or been cleaned more than 5      
times, you have to replace it.

Note:
Be sure not to take apart the air filter during         

driving.

General Maintenance

Do not clean the filter cartridge with gaso-       

line or water.

Check the cyclone boot for wear when      

clean it, replace it if it is worn.

Install the filter cartridge and cyclone  boot      

correctly, otherwise the dust will come into and       
shorten the service life of the engine.

When installing,check every seal ring for     

wear, replace or stick it if it is  damaged.  Every         
seal ring should not be lost or missed.

Diesel Oil Prefilter

Drain the water every 12000km,    

and replace the prefilter every 

 

 

 

36000km.

Fuel Filter and Fuel-water Separa-

tor

Replace it every 16000km.
Use the special wrench to disas-     

semble the fuel filter and fuel-water     
separator. 

Before  you  installing  the  filter     

manually, fill it with clean diesel oil until the        
sealing surface is engaged with the con-      
necting surface, you can screw for 3/4 cir-       
cle to tighten it.

Note:
Do  not  use  the  special  wrench  during      

installation, otherwise it will deform the thread      
and damage the filter finally.

Oil Filter

The engine is equipped with a spin-on      

filter  for  lubricating  oil  which  is  one-time      
used.  Replace  the  oil  filter  every  interval      
10,000km. Use  special  filter  wrench  to     
remove the filter. When  assemble  a  new      
filter, first fill the filter with clean lubricating

oil,  and  apply  oil  on  the  surface  of  the  oil         
seal, then assemble the filter by hand. After       
the sealing surface engaged with the con-      
necting surface, you can screw for 3/4 cir-       
cle to tighten it. Start the  engine  to  check        
the sealing surface for leakage.  If  there  is       
any   leakage,  tighten  it  until  there  is  no        
leakage.

Note:
Do not use the special wrench during      

installation, otherwise it will deform the thread      
and damage the filter finally.

Fuel Tank Draining

Screw off the fuel drain plug at the       

bottom of the tank to drain the dirt and        
water every 12,000Km. Till the clean     
diesel oil flow out, screw up the plug       
immediately.  Especially  in  winter,   
because the water is easy to ice and       
cut off the supply of the diesel oil,       
please do remember to drain.

Fuel Pump

In the pump's fuel pipe,  there  is  a       

joint bolt is installed a gauze filter to       
filter diesel oil.  Be  sure  to  wash  the       
gauze with clean diesel oil every 

 

 

 

 

4,000km. If damaged, replace it in time,      
or it will influence the fuel supply.

If the manual pump piston is 

 

 

 

 

blocked, check the fuel pipe bolt gauze      
filter to see whether it is damaged or       
not. Remove the manual pump 

 

 

 

assembly and soak it into clean  diesel      
oil for a long time. If it is seized, replace         
the manual pump assembly.
