10.1 Preparation data
Operation precautions
Rod worm should rotate flexible, without stagnation and unilateral tightness while worm gear should have a little
axial movement and the machine oil pump o-shaped ring shall not have cutting edge.
Each plug of the machine oil pump should not leak and the sealing ring should be complete.
After installation, the bolt3 should be removed in trial running and fasten it up when there is
continuous oil flowing out.
The function of the lubricating system: the function of the engine lubricating system is to provide
lubricating oil for machine parts friction surface to turn dry friction of the surface into wet friction,
thus reducing the wear between the parts; to cool down the parts with high heat load; to absorb the
impact of the bearing and other machine parts and reduce the noise; to increase the sealing between
the piston ring and cylinder; to clean the parts and take away the impurity on them.

10.2 Fault diagnosis
Machine oil amount decreasing Engine being burned out
Machine oil decreases naturally No machine oil or the oil pressure is too low
Machine oil leaks piston pathway obstructs
The piston ring has been worn out
or the installation is not good No machine oil has been used
