LUBRICATION  

4-1 Oil 

 

Use Kansai Special’s genuine oil. 
(Part No. 28-613 : 1000 cc) 

 
 
 

4-2 To fill the machine with oil 

Remove rubber plug A from the oil hole. 
Fill the machine with oil until the oil level is at the 
top line (see H in the illustration) on oil gauge C. 
After the first lubrication, add oil so that the oil 
level will be between H and L. 
After filling the machine with oil, run the machine 
to check the oil is splashing onto oil pot A. 

 
 
 
 
 

4-3 Replacing the oil and the oil element 

To extend machine life, be sure to replace the oil 
after the first 250 hours of operation. 
To replace the oil, follow the procedures below. 

 

1.

 

Remove the V belt from the motor pulley and 
then remove the machine from the table. 

2.

 

Remove screw D and then drain the oil. 
Be careful not to stain V belt with the oil. 

3.

 

After draining the oil, be sure to tighten screw 
D. 

4.

 

Fill the machine with oil by referring to 4-2 
shown above. 

 

If element E is contaminated, proper oiling may not be performed. 
Clean the filter element every six months.  If just a little or no oil flows out from the 
nozzle with the proper amount of oil in the machine, check the element. 
To do so, remove oil filter cap F.    Replace the element if necessary. 

 

< Note > 
When the oil filter cap is rem ved, the oil collected on the element drips.    Be careful.
