JAT-100 Butterfly Impact Wrench 

 

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 Impact Wrench 

35.  This impact wrench is designed for removing 

and installing threaded fasteners. If you are 
not familiar with the proper and safe operation 
of a pneumatic impact wrench, do not use until 
proper training and knowledge have been 
obtained. 

36.  Use only impact sockets in good condition. 

Sockets in poor condition may reduce impact 
power, and could break, creating a safety 
hazard.  

37.  Use only sockets designated for use with 

impact wrenches. Never use hand tool 
sockets, as they can shatter. 

38.  Never hold socket, drive or drive extension 

with your hand during operation. 

39.  Make sure workpiece is secure and will not 

shift while operating impact wrench. Do not 
hold workpieces with your hand. 

40. Make sure fastener can withstand rated 

torque of impact wrench.
