Additional Safety for Mills

Like all machinery there is potential danger 

when operating this machine. Accidents 

are frequently caused by lack of familiarity 

or failure to pay attention. Use this machine 

with respect and caution to decrease the 

risk of operator injury. If normal safety pre-

cautions are overlooked or ignored, seri-

ous personal injury may occur.

No list of safety guidelines can be com-

plete. Every shop environment is different. 

Always consider safety first, as it applies 

to your individual working conditions. Use 

this and other machinery with caution and 

respect. Failure to do so could result in 

serious personal injury, damage to equip-

ment, or poor work results.

UNDERSTANDING CONTROLS.  The  mill  is  a 
complex  machine.  To  reduce  the  risk  of  injury, 
make sure you understand the use and operation 
of all controls before you begin milling.

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.

STOPPING SPINDLE.  Always  allow  the  spindle 
to  stop  on  its  own.  To  reduce  the  risk  of  lacera-
tions, entanglement, or breakage debris, DO NOT 
attempt  to  stop  the  spindle  with  your  hand  or  a 
tool. 

SAFETY ACCESSORIES. Flying chips or debris 
from the cutting operation can cause eye injury or 
blindness. To reduce this risk, always use a face 
shield  in  addition  to  your  safety  glasses  when 
milling.

WORK HOLDING. Attempting to mill a workpiece 
that  is  not  properly  secured  could  cause  break-
age  debris  to  fly  at  the  operator.  Before  starting 
the machine, be certain the workpiece has been 
properly clamped to the table or secured in a vise. 
NEVER hold the workpiece by hand during opera-
tion.

CHIP CLEANUP. Waste chips created by the mill-
ing  operation  are  sharp  and  hot  and  can  cause 
cuts or burns. Using compressed air to clear chips 
could blow them into your eyes or 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.  NEVER  clear  chips  while 
the spindle is turning.

MACHINE CARE & MAINTENANCE.  Operating 
the  mill  with  excessively  worn  or  damaged  parts 
increases  the  risk  of  accidents  that  could  cause 
serious  injuries.  A  mill  that  is  maintained  poorly 
will  produce  poor  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  results  and  reduces  the  risk  of 
personal  injury  from  broken  tool  debris.  Inspect 
cutting tools for sharpness, chips, or cracks before 
each  use.  ALWAYS  make  sure  cutting  tools  are 
firmly held in place before starting machine.
