1) Work area safety
a) Keep work area clean and well lit. 
Cluttered or dark areas invite 
accidents.
b) 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.
c) Keep children and bystanders away 
while operating a power tool. 
Distractions can cause you to lose 
control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or 
wet conditions. Water entering a 
power tool will increase the risk of 
electric shock.
d) 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.
e) When operating a power tool 
outdoors, use an extension cord 
suitable for outdoor use. Use of a 
cord suitable for outdoor use 
reduces the risk of electric shock.
f) If operating a power tool in a damp 
location is unavoidable, use a 
residual current device (RCD) 
protected supply. Use of an RCD 
reduces the risk of electric shock.
3) Personal safety
a) 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.
b) Use personal protective equipment. 
Always wear eye protection. 
Protective equipment such as dust 
mask, non-skid safety shoes, hard 
hat, or hearing protection used for 
appropriate conditions will reduce 
personal injuries.
