PRECAUTIONS FOR DISCONNECTION AND CONNECTION OF PIPINGS
When performing "testing and adjusting" of the machine, "removal and installation" and "disassembly and as-
sembly" of the components, observe the following precautions.
Precautions for removal and disassembling 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 dust from entering.
•
When draining oil, prepare a container with sufficient capacity.
•
Check the matchmarks which indicate the installing position, and put matchmarks 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 discon-
necting the connectors. Do not pull the wires.
•
Attach the tags to wires and hoses so that installation is done to the correct installing positions.
•
Check the thickness and number of shims when storing shims.
•
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 for-
eign material from entering after removal.
•
After disconnecting the piping or removing a pipe joint, install the following plugs.
NOTICE
When disassembling the machine, check the part number by referring to the Parts Book and use the
appropriate parts according to the usage conditions.
REMARK
The part numbers of O-ring shown in the table indicate the temporary part number when disassembling and
transporting the machine.
