5 Checks before operation
5.1 Check the machine
In order to operate the machine safely and keep it in good condition, a thorough check must be
made before it is started.
Basic principles
★The operator should be responsible for the pre-operation check and routine maintenance.
★The pre-operation check is a visual inspection process, which is performed by the operator
before each work shift. The purpose of the pre-operation check is to find obvious problems with
the machine before the operator performs the function test.
★The pre-operation check can also be used to determine whether routine maintenance is
required. The operator can only perform the routine maintenance items specified in this manual.
★Refer to the list attached to the machine and parts and check each item and location for
changes, damage, looseness or missing parts.
★Do not use damaged or altered machines. Mark the machine and stop using it if any damage or
any changes to the original machine are found.
★According to the manufacturer's regulations, only qualified service technicians can repair the
machine. After the maintenance, the operator must perform another pre-operation check before
performing the function test.
★According to the manufacturer's regulations and the requirements stated in the duty manual,
regular maintenance and inspections should be performed by qualified maintenance technicians.
Check items
★Ensure that the operation manual and maintenance manual are intact, easy to understand, and
kept in the storage case on the platform.
★Ensure that all labels and signs are clear and visible and stuck in the proper positions. See the
section “Labels and Signs”.
★Check for any leakage of hydraulic oil and its level. Add hydraulic oil as needed, do not overfill.
