Additional Safety Instructions for Mills
Like all machinery there is potential danger when operating this mill. Accidents are frequently
caused by lack of familiarity or failure to pay attention. use this mill with respect and caution to
reduce the risk of operator injury. If normal safety precautions are overlooked or ignored, serious
personal injury may occur.
uNdERSTANdING CONTROLS: the mill is a
complex machine that presents severe cutting or
entanglement hazards if used incorrectly. Make
sure you understand the use and operation of all
controls before you begin milling.
SAfETy ACCESSORIES: Flying chips or debris
from the cutting operation can cause eye injury
or blindness. always use a chip guard in addition
to your safety glasses, or use a face shield when
milling.
WORK HOLdING: Milling a workpiece that is not
properly clamped to the table could cause the
workpiece to be thrown at the operator with deadly
force! Before starting the machine, be certain
the workpiece has been properly clamped to the
table. nEvEr hold the workpiece by hand during
operation.
SpINdLE SpEEd: to avoid tool or workpiece
breakage that could send flying debris at the
operator and bystanders, use the correct spindle
speed and feed rate for the operation. allow the
mill to gain full speed before beginning the cut.
SpINdLE dIRECTION CHANGE: Changing
spindle rotation direction while it is spinning could
lead to gear damage or impact injury from broken
tool or workpiece debris. alWays make sure the
spindle has completely stopped before changing
spindle direction.
STOppING SpINdLE: to reduce the risk of
hand injuries or entanglement hazards, Do not
attempt to stop the spindle with your hand or a
tool. allow the spindle to stop on its own or use
the spindle brake.
CHIp CLEANup: Chips from the operation are
sharp and hot and can cause cuts or burns. using
compressed air to clear chips could cause them
to fly into your eyes and may drive them deep into
the working parts of the machine. use a brush or
vacuum to clear away chips and debris from the
machine or workpiece and nEvEr clear chips
while the spindle is turning.
MACHINE CARE ANd MAINTENANCE:
operating the mill with excessively worn or dam-
aged machine parts increases the risk of machine
or workpiece breakage, which could eject hazard-
ous debris at the operator. operating a mill that
is in poor condition will also reduce the quality of
the results. to reduce this risk, maintain the mill
in proper working condition by alWays promptly
performing routine inspections and maintenance.
CuTTING TOOL uSAGE: Cutting tools have
very sharp leading edges—handle them with
care! using cutting tools that are in good condition
helps to ensure quality milling results and reduces
the risk of personal injury from broken tool debris.
inspect cutting tools for sharpness, chips, or
cracks before each use, and alWays make sure
the cutting tools are firmly held in place before
starting the machine.
