25.  Give  your  work  undivided  attention.  Looking 

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

26.  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. 

27.  Repetitive  motions  and/or  exposure  to 

constant  vibration  can  be  harmful  to  hands 
and  arms.  Take  frequent  breaks  and  relax 
hands  during  extended  operation.  Change 
posture to avoid discomfort or fatigue. 

28.  Compressed  air  can  be  harmful  if  directed 

toward sensitive areas of the body, and may 
propel small particles caught in the air stream. 
Exercise proper caution. 

29.  Use 

only 

recommended 

accessories; 

improper accessories may be hazardous. 

30.  Maintain  tools  with  care.  Keep  air  tool  clean 

and oiled for best and safest performance. 

31.  Do  not  use  combustible  gases,  carbon 

dioxide, oxygen  or  any  bottled  gas  as  an  air 
source for the tool. These can present risk of 
explosion and serious injury. 

32.  Do  not  lubricate  the  tool  with  combustible 

liquids, such as kerosene, diesel or jet fuel. 

33.  Do  not  dispose  of  this  tool  with  normal 

household waste. Never dispose of the air tool 
into fire. 

Specific warnings for Polishers 

34.  If you are not familiar with the proper and safe 

operation of a pneumatic polisher, do not use 
until proper training and knowledge have been 
obtained. 

35.  Secure workpiece with clamps or vise; do not 

hold workpiece by hand. 

36.  Only use accessories that are intended for use 

with a pneumatic polisher. Do not modify the 
tool or use bushings, adaptors, etc. to mount 
accessories that are not designed for the tool. 

37.  Speed rating of polishing pad must match or 

exceed free speed rating of sander. 

38.  Use both hands to operate this polisher. Use 

side handle if tool is provided with one. 

39.  Inspect  pads  and  discs  for  any  fractures, 

nicks,  deformation,  lack  of  concentricity,  or 
other damage. Do not use a damaged backing 
pad or polishing pad.
