• When performing "testing and adjusting" of the machine, "removal and installation" and "disassembly and
assembly" of the components, observe the following general cautions.
Precautions for removal and disassembly work
• If the cooling water contains coolant, dispose of it correctly as chemicals. Do not drain it to the sewage
rashly.
• After disconnecting the hoses or tubes, plug them to prevent dirt or dust from entering.
• When draining oil, prepare a container with sufficient capacity.
• Check the match marks which indicate the installing position, and put match marks on the places where
they seem necessary before removal of the components to prevent any mistake when assembling.
• To prevent any excessive force from being applied to the wiring, always hold the connectors when
disconnecting the connectors. Do not pull the wires.
• Attach the tags to wires and hoses to show their installing positions to prevent any mistake when
installing.
• Check the number and thickness of the shims, and keep them in a safe place.
• When hoisting the components, prepare the slings with sufficient strength.
• When using forcing screws to remove any component, tighten the forcing screws uniformly and
alternately.
• Before removing any component, clean the surrounding area and cover the component to prevent any
foreign material from entering after removal.
• After disconnecting the piping or removing a pipe joint, install the following plugs.
a The O-rings in the table are emergency parts used for disassembly or transportation of the machine.
When assembling, confirm the part numbers in the parts book and use the parts conforming to the
using condition.
