  Safety warnings 

1.  Read  and  understand  the  entire  owner's 

manual  before  attempting  assembly  or 
operation. 

2.  Read and understand the warnings posted on 

the  machine  and  in  this  manual.  Failure  to 
comply  with  all  of  these  warnings  may  cause 
serious  injury.  Replace  warning  labels  if  they 
become obscured or removed. 

3.  This turret mill is designed and intended for use 

by properly trained and experienced personnel 
only. If you are not familiar with the proper and 
safe  operation  of  a  turret  mill  do  not  use  until 
proper  training  and  knowledge  have  been 
obtained. 

4.  Do  not  use  this  turret  mill  for  other  than  its 

intended  use.  If  used  for  other  purposes,  JET 
disclaims any real or implied warranty and holds 
itself  harmless  from  any  injury  that  may  result 
from that use. 

5.  Always  wear  approved  safety  glasses/face 

shields  while  using  this  turret  mill.  Everyday 
eyeglasses  only  have  impact  resistant  lenses; 
they are not safety glasses. 

6.  Before  operating  this  turret  mill,  remove  tie, 

rings,  watches  and  other  jewelry,  and  roll 
sleeves up past the elbows. Do not wear loose 
clothing. Confine long hair. Non-slip footwear or 
anti-skid floor strips are recommended. Do not 
wear gloves. 

7.  Wear  ear  protectors  (plugs  or  muffs)  during 

extended periods of operation. 

8.  Do not operate this machine while tired or under 

the  influence  of  drugs,  alcohol  or  any 
medication. 

9.  Make certain the switch is in the OFF position 

before  connecting  the  machine  to  the  power 
supply. 

10.  Make certain the machine is properly grounded. 

11.  Make all machine adjustments or maintenance 

with  the  machine  unplugged  from  the  power 
source. 

12.  Remove adjusting keys and wrenches. Form a 

habit of checking to see that keys and adjusting 
wrenches  are  removed  from  the  machine 
before turning it on.  

13.  Keep safety guards in place at all times when 

the  machine  is  in  use.  If  removed  for 
maintenance  purposes,  use  extreme  caution 

and  replace  the  guards  immediately  after 
completion of maintenance. 

14.  Check damaged parts. Before further use of the 

machine, a guard or other part that is damaged 
should be carefully checked to determine that it 
will  operate  properly  and  perform  its  intended 
function. Check for alignment of moving parts, 
binding  of  moving  parts,  breakage  of  parts, 
mounting  and  any  other  conditions  that  may 
affect its operation. A guard or other part that is 
damaged  should  be  properly  repaired  or 
replaced. 

15.  Do not use power tools in damp/wet locations 

or other dangerous environments.  

16.  Do  not  expose  them  to  rain.  Provide  for 

adequate  space  surrounding  work  area  and 
non-glare, overhead lighting. 

17.  Keep  the  floor  around  the  machine  clean  and 

free of scrap material, oil and grease. 

18.  Keep  visitors  a  safe  distance  from  the  work 

area. Keep children away. Workshop should be 
child proof with padlocks, master switches or by 
removing starter keys. 

19.  Give  your  work  undivided  attention.  Looking 

around, carrying on a conversation and “horse-
play” are careless acts that can result in serious 
injury. 

20.  Maintain a balanced stance at all times so that 

you do not fall against cutters or other moving 
parts. Do not overreach or use excessive force 
to perform any machine operation. 

21.  Use the right tool at the correct speed and feed 

rate. Do not force a tool or attachment to do a 
job for which it was not designed. The right tool 
will do the job better and more safely. 

22.  Use  recommended  accessories;  improper 

accessories may be hazardous. 

23.  Maintain  tools  with  care.  Keep  cutters  sharp 

and clean for the best and safest performance. 
Follow instructions for lubricating and changing 
accessories. 

24.  Turn  off  the  machine  before  cleaning.  Use  a 

brush  or  compressed  air  to  remove  chips  or 
debris — do not use your hands. 

25.  Do  not  stand  on  the  machine.  Serious  injury 

could occur if the machine tips over. 

26.  Never  leave  the  machine  running  unattended. 

Turn  the  power  off  and  do  not  leave  the 
machine until it comes to a complete stop. 

27.  Remove  loose  items  and  unnecessary  work 

pieces  from  the  area  before  starting  the 
machine.
