Initial Safety Checks

Before the lathe is used for any machining
operations, it should be checked for proper
Use the handwheels to move the carriage,
cross-slide and compound through their full
range of motion.
Turn the chuck by hand through a few full
turns. Ensure that the gears in the gear
train on the left side of the lathe are turning
smoothly. Verify that everything is moving
If the chuck is installed in the spindle,
ensure that all of the retaining nuts are tight
and that the chuck key has been removed.
Turn on the red power switch. The digital
tachometer should display 0000 and the
sound of the cooling fan should be heard.
Ensure that the cutting tool is clear of the
chuck, then lower the chuck safety shield.
The lathe will not start with the safety shield
in the raised position.
Press the green START button to start the
spindle rotation.
Use the é and ê
increase the spindle speed from slow to

Regular Safety Checks – Each Time
Machine is Used
Before beginning any cutting operation:
glasses or use a safety face shield when
operating the lathe.
Make sure that the chuck key has been
removed from the chuck.
Clear away any strands of material that
may be left from prior operations from the
area of the chuck.
Loose material could become entangled in
the chuck or the workpiece and pose a
Lower the chuck safety shield over the
chuck. The motor will not start with the
guard in the raised position.
Be sure that the work is securely held in
the chuck jaws and not mounted at a
skewed angle. Grasp the end of the
workpiece and attempt to move it – make
sure that it is not loose.
Verify that the cutting tool and any other
objects are clear of the chuck and the
workpiece before starting the lathe.
Clear the work area of any objects that
could cause you trip or slip; also any tools
or other objects on or near the lathe that
are not required for the current operation.
Avoid loose sleeves or loosely fitting shirts
that could become entangled in rotating
parts. Remove or secure necklaces and
other jewelry.
Tie back long hair to avoid getting it
entangled in the rotating chuck and
Use recommended cutting fluids to reduce
the force required by the cutting tool. This
will help keep the tool cooler and increase
its life, and will make it less likely that chips
will weld to the tool or workpiece causing
rough surface finishes.
