SAFETY WARNINGS

General power tool safety warnings

WARNING:

 

Read all safety warnings, instruc-

tions, illustrations and specifications provided 

with this power tool.

 Failure to follow all instructions 

listed below may result in electric shock, fire and/or 

serious injury.

Save all warnings and instruc-

tions for future reference.

The term "power tool" in the warnings refers to your 

mains-operated (corded) power tool or battery-operated 

(cordless) 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 atmo-

spheres, 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

1. 

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.

2. 

Avoid body contact with earthed or grounded 

surfaces, such as pipes, radiators, ranges and 

refrigerators.

 There is an increased risk of elec-

tric shock if your body is earthed or grounded.

3. 

Do not expose power tools to rain or wet con-

ditions.

 Water entering a power tool will increase 

the risk of electric shock.
