Nozzle clogging

Can be used to dredge the needle, dredge after careful cleaning.Needle valve body plane and jet nozzle body plane contact bad, or needle valve cylinder wear.If the large plane of the needle valve body is in bad contact with the plane of the main body of the nozzle, chromium oxide can be applied to the flat plate for "8" shape grinding;If needle valve cylinder wear, should be in pairs to replace the needle valve couple.

sealed

Poor sealing of needle valve and needle body, resulting in poor atomization or oil dripping nozzle.

This kind of fault may use the fine chromium oxide or the toothpaste, besmeared in the needle valve end seal belt, but must not besmeared to the cylinder part, then inserts the needle valve into the needle body, while knocks turns until close.Chrome oxide or toothpaste must be washed off after grinding.

 Air

There is air in the oil route.Simply remove the air from the fuel line.

Drainage not free

The oil pump needs to be overhauled.If the oil pipeline joint leaks, try to connect it well so that it does not leak.

Lack of elasticity

Insufficient spring force of the piston spring or broken spring.The spring should be replaced.

The piston wear

Piston wear affects oil supply.The piston needs to be replaced.
