General Power Tool Safety 
 
WARNING Read all safety warnings and all instructions.  Failure to follow the 
warnings and instructions may result in serious personal injury or damage to property. 
 
Save all warnings and instructions for future reference. 
The term “power tool” in the warnings refers to your corded (electric) or cordless (battery 
operated) power tool. 
 
Work Area Safety 
 
1. Keep work area clean and well lit.  Cluttered or dark areas invite accidents. 
2. Do not operate power tools in explosive atmospheres, such as in the presence of 
flammable liquids, gases or dust.  Power tools create sparks which may ignite the 
dust or fumes. 
3. Keep children and bystanders away while operating a power tool.  Distractions can 
cause you to lose control. 
 
Electrical Safety 
 
4. Power tool plugs must match the outlet.  Never modify the plug in any way.  Do 
not use any adapter plugs with earthed (grounded) power tools.  Unmodified plugs 
and matching outlets will reduce risk of electric shock. 
5. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, 
ranges and refrigerators.  There is an increased risk of electric shock if your body is 
earthed or grounded.

6. Do not expose power tools to rain or wet conditions.  Water entering a power tool 
will increase the risk of electric shock. 
7. Do not abuse the cord.  Never use the cord for carrying, pulling or unplugging the 
power tool.  Keep cord away from heat, oil, sharp edges or moving parts.  
Damaged or entangled cords increase the risk of electric shock. 
8. When operating a power tool outdoors, use an extension cord suitable for 
outdoor use.  The use of a cord suitable for outdoor use reduces the risk of electric 
shock. 
9. If operating a power tool in a damp location is unavoidable, use a ground fault 
circuit interrupter (GFCI) protected electrical supply.  Use of a GFCI reduces the 
risk of electric shock. 
 
Personal Safety 
 
10. Stay alert, watch what you are doing and use common sense when operating a 
power tool.  Do not use a power tool while you are tired or under the influence of 
drugs, alcohol or medication.  A moment of inattention while operating power tools 
may result in serious personal injury. 
11. Use personal protective equipment.  Always wear eye protection.  Protective 
equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection 
used for the appropriate conditions will reduce personal injuries. 
12. Prevent unintentional starting.  Ensure the switch is in the off-position before 
connecting to the power source and/or battery pack, picking up or carrying the 
tool.  Carrying power tools with your finger on the switch or energizing power tools that 
have the switch on invites accidents. 
13. Remove any adjusting key or wrench before turning the power tool on.  A wrench 
or key left attached to a rotating part of the power tool may result in personal injury. 
14. Do not overreach.  Keep proper footing and balance at all times.  This enables you 
to maintain better control over the power tool in unexpected situations. 
15. Dress properly.  Do not wear loose clothing or jewelry.  Keep your hair, clothing 
and gloves away from moving parts.  Loose clothes, jewelry or long hair can be 
caught in moving parts. 
16. If devices are provided for the connection of dust extraction and collection 
facilities, ensure these are properly connected and properly used.  Use of dust 
collection can reduce dust-related hazards. 
 
Power Tool Use and Care 
 
17. Do not force the power tool.  Use the correct power tool for your application.  The 
correct power tool will do the job better and safer at the rate for which it was designed. 
18. Do not use the power tool if the switch does not turn it on and off.  Any power tool 
that cannot be controlled with the switch is dangerous and must be repaired. 
19. Disconnect the plug from the power source and/or the battery pack from the 
power tool before making any adjustments, changing accessories, or storing 
power tools.  Such preventative safety measures reduce the risk of starting the power 
tool accidentally.

20. Store idle power tools out of the reach of children and do not allow persons 
unfamiliar with the power tool or these instructions to operate the power tool.  
Power tools are dangerous in the hands of untrained users. 
21. Maintain power tools.  Check for misalignment or binding of moving parts, 
breakage of parts and any other condition that may affect the power tools 
operation.  If damaged, have the power tool repaired before use.  Many accidents 
are caused by poorly maintained power tools. 
22. Keep cutting tools sharp and clean.  Properly maintained cutting tools with sharp 
cutting edges are less likely to bind and are easier to control. 
23. Use the power tool, accessories and tool bits, etc. in accordance with these 
instructions, taking into account the working conditions and the work to be 
performed.  Use of the power tool for operations different from those intended could 
result in a hazardous situation. 
 
 
 
Cordless Tool Use and Care 
 
24. Recharge only with the charger specified by the manufacturer.  A charger that is 
suitable for one type of battery pack may create a risk of fire when used with another 
battery pack. 
25. Use power tools only with specifically designated battery packs.  Use of any other 
battery packs may create a risk of injury and fire. 
26. When the battery pack is not in use, keep it away from other metal objects like 
paper clips, coins, keys, nails, screws or other small metal objects that can make 
a connection from one terminal to another.  Shorting the battery terminals together 
may cause burns or a fire. 
27. Under abusive conditions, liquid may be ejected from the battery; avoid contact.  
If contact accidentally occurs, flush with water.  If liquid contacts eyes, seek 
medical help immediately.  Liquid ejected from the battery may cause irritation or 
burns. 
 
Service 
 
28. Have your power tool serviced by a qualified repair person using only identical 
replacement parts.  This will ensure that the safety of the power tool is maintained. 
29. Follow instructions for lubricating and changing accessories. 
30. Keep handles dry, clean and free from oil and grease.
