NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardized test
given in EN 61029 and may be used to compare one tool with another. It may be used for a preliminary assessment
of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is
used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total working period. An estimation of the level of exposure to
vibration should also take into account the times when the tool is switched off or when it is running but not actually
doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety
measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep
the hands warm, organization of work patterns.

4 Safety instructions

4.1 General Power Tool Safety Warnings
a)
WARNING
Read all safety warnings and all instructions. Fail-
ure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury. Save all
warnings and instructions for future reference.
The term "power tool" in the warnings refers to
your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
4.1.1 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 atmo-
spheres, 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 operat-
ing a power tool. Distractions can cause you to lose
control.
4.1.2 Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any ad-
apter 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.
