Maintenance
Regular maintenance is necessary for the high performance of the machine. The viewpoint that the
the machine doesn’t need to be checked regularly if the machine can be used normally is absolutely wrong.
Proper examination and maintenance not only can extend the working life of the machine but also find
the malfunctions and deal with them in time, in this way, the maintenance time and cost can be reduced
significantly.
11 Lubricant, Fuel, and Other Liquids, 111 Lubricant
Lubricant can help to prevent the wear of fitting surfaces and noise.
The connectors (pipe joint, connecting set) that are not involved in this manual are only for overhauling and not need to add lubricant. But be sure to fill the lubricant if some parts are difficult to operate after a long time of use.
Clear the spilled lubricant after filling.
112 Fuel
A fuel pump is a precise device, and it will not work normally if the fuel is mixed with water
and other impurities.
