GENERAL SAFETY RULES

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 atmo-

spheres, such as in the presence of flammable liquids, 

gases or dust.

 Power tools create sparks which may ig-

nite the dust or fumes.

3. Keep children and bystanders away while operating 

a power tool.

 Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never mod-

ify 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.

2. Avoid body contact with earthed or grounded surfac-

es such as pipes, radiators, ranges and refrigerators.

 

There is an increased risk of electric shock if your body 

is earthed or grounded.

3. Do not expose power tools to rain or wet conditions.

 

Water entering a power tool will increase the risk of elec-

tric shock.

4. Do not abuse the cord. Never use the cord for car-

rying, 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.

5. When operating a power tool outdoors, use an ex-

tension cord suitable for outdoor use. 

Use of a cord 

suitable for outdoor use reduces the risk of electric 

shock.  

6. If operating a power tool in a damp location is un-

avoidable, use a ground fault circuit interrupter (GFCI) 

protected supply. 

Use of a GFCI reduces the risk of elec-

tric shock.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use com-

mon 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 inatten-

tion while operating power tools may result in serious 

personal injury.

2. Use personal protective equipment. Always wear 

eye protection. 

Protective equipment such as a respira-

tory mask, non-skid safety shoes and hearing protection 

used for appropriate conditions will reduce the risk of 

personal injury.

3. Prevent unintentional starting. Ensure the switch is 

in the off-position before connecting to 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.

4. Remove any adjusting key or wrench before turning 

the power tool on.

 A wrench or a key left attached to a 

rotating part of the power tool may result in personal 

injury. 

5. Do not overreach. Keep proper footing and balance 

at all times.

 This enables better control of the power 

tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or jew-

elry. Keep your hair and clothing away from moving 

parts. 

Loose clothes, jewelry or long hair can be caught 

in moving parts.

Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” 

in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

WARNING!

 Read all safety warnings and all instructions. Failure to follow the warnings and instructions may 

result in electric shock, fire and/or serious injury.
