WARNINGS AND CAUTIONS RELATED TO
HANDLING
This section presents safety precautions related to the handling of machine tools. Before attempting to
operate your machine, read the supplied operator’s manual and programming manual carefully, such
that you are fully familiar with their contents.
WARNING
1.Manual operation
When operating the machine manually, determine the current position of the tool and workpiece, and
ensure that the movement axis, direction, and feedrate have been specified correctly. Incorrect
operation of the machine may damage the tool, the machine itself, the workpiece, or cause injury to the
operator.
2.Manual reference position return
After switching on the power, perform manual reference position return as required.
If the machine is operated without first performing manual reference position return, it may behave
unexpectedly. Stroke check is not possible before manual reference position return is performed.
An unexpected operation of the machine may damage the tool, the machine itself, the workpiece, or
cause injury to the user.
3.Manual numeric command
When issuing a manual numeric command, determine the current position of the tool and workpiece,
and ensure that the movement axis, direction, and command have been specified correctly, and that the
entered values are valid.
Attempting to operate the machine with an invalid command specified may damage the tool, the
machine itself, the workpiece, or cause injury to the operator.
4.Manual handle feed
In manual handle feed, rotating the handle with a large scale factor, such as 100, applied causes the tool
and table to move rapidly. Careless handling may damage the tool and/or machine, or cause injury to
the user.
5.Disabled override
If override is disabled (according to the specification in a macro variable) during threading, rigid
tapping, or other tapping, the speed cannot be predicted, possibly damaging the tool, the machine itself,
the workpiece, or causing injury to the operator.
6.Origin/preset operation
Basically, never attempt an origin/preset operation when the machine is operating under the control of a
program. Otherwise, the machine may behave unexpectedly, possibly damaging the tool, the machine
itself, the tool, or causing injury to the user.
