Hazardous waste disposal
Promote environmental protection and pay special attention to methods of waste disposal:
● Put the oil discharged from the machine into a container. Do not discharge the oil directly onto the ground, or pour it into
sewers, drains, rivers, oceans or lakes.
● During handling of hazardous materials, such as oil, fuel, coolant, antifreeze, plastic accessories, solvents, filter
elements, batteries and other hazardous materials, the relevant environmental protection laws and regulations shall be
followed.
Prevent articles from falling into the machine
● During inspection when opening the fuel tank nozzle, be careful not to drop bolts, nuts, washers or tools inside the
machine. If these articles fall into the machine, this will cause damage and malfunction of the machine, and may lead to
accidents. If something falls into the machine, take it out immediately.
● Before and after the inspection, check the tools and parts you carried to make sure that nothing has fallen into the
machine.
Regular inspection and maintenance
Regular inspection and maintenance shall be carried out in accordance with the items listed in the "Regular Inspection
and Maintenance Table", which is an important prerequisite for ensuring the normal operation of the machine and
prolonging its service life. Be sure to observe the inspection and maintenance cycle.
Recheck after inspection and maintenance
If recheck is not carried out after each inspection and maintenance, unexpected failures may occur, resulting in serious
injury or damage. Pay attention to check the following:
● Are there any other parts that shall be inspected and maintained?
● Whether all inspection and maintenance items have been carried out correctly.
● Check whether any tools or parts have fallen into the machine. It is very dangerous if any parts fall into the machine and
jam into the linkage mechanism.
● Check around the machine to check if there is water or oil leakage and all bolts have been tightened.
