2)Maintenance

If the test results are found notgood (poor injection and "after dripping"), carefully check and repair in the following manner:

a)Disassemble the nozzle holder and nozzle, andwash in clean light oil. When washng, use a wooden chip

(for instance, wooden chopstick is servicable.) for

 

peeling off the carbon adheredt o the nozzle.
