20.  Do not use power tools in damp or wet 

location, or expose them to rain. Keep work 
area well lighted. 

21.  Do not leave a connected tool unattended. 

When not in use, disconnect tool from air 
source. 

22.  Shut off air supply and discharge any residual 

pressure from tool before removing hose, 
making adjustments, changing accessories, 
or storing tool. 

23.  Make sure tool is switched off, and your finger 

off the trigger, before connecting to air supply. 

24.  Remove adjusting keys and wrenches before 

turning on tool. 

25.  Keep visitors a safe distance from the work 

area. 

Keep children away.

 

26.  Give your work undivided attention. Looking 

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

27.  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. 

28. 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. 

29.  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. 

30. 

Use only recommended accessories; 
improper accessories may be hazardous. 

31.  Maintain tools with care. Keep air tool clean 

and oiled for best and safest performance. 

32. 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. 

33.  Do not lubricate the tool with combustible 

liquids, such as kerosene, diesel or jet fuel. 

34.  Do not dispose of this tool with normal 

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

Specific warnings for Belt Sanders 

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

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

36.  Secure workpiece with clamps or vise; do not 

hold workpiece by hand. 

37.  Only use accessories that are intended for use 

with a pneumatic belt sander.  

38.  Use both hands to operate sander. 

39.  Inspect abrasive belt before operating. Do not 

use a damaged belt. 

40.  Do not operate sander without the silencer 

(muffler) installed.
