4. WARNINGS AND CAUTIONS RELATED TO
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.
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 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.
4. Disabled override
If override is disabled (according to the specification in a
macro variable) during rigid tapping or other tapping, the
speed cannot be predicted, possibly damaging the tool,
the machine itself, the workpiece, or causing injury to the
5. 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.
