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.
WARNING: The noise emission during actual
use of the power tool can differ from the declared val-
ue(s) depending on the ways in which the tool is used
especially what kind of workpiece is processed.
Work area safety
WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (tak-
ing account of all parts of the operating cycle such
as the times when the tool is switched off and when
it is running idle in addition to the trigger time).
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.

Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
NOTE: The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
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.
NOTE: The declared vibration total value(s) may also
be used in a preliminary assessment of exposure.
WARNING: The vibration emission during actual
use of the power tool can differ from the declared val-
ue(s) depending on the ways in which the tool is used
especially what kind of workpiece is processed.
5.
6.
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.
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.
WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (tak-
ing account of all parts of the operating cycle such
as the times when the tool is switched off and when
it is running idle in addition to the trigger time).

proper fastening time for your bolt or nut.
Hold the tool firmly and place the impact socket over
the bolt or nut. Turn the tool on and fasten for the proper
fastening time.
NOTE: If the tool is operated continuously until the
battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery
cartridge.
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.

The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.

Even though the torque coefficient and the
class of bolt are the same, the proper fasten-
ing torque will differ according to the diame-
ter of bolt.

The use of the universal joint or the extension
bar somewhat reduces the fastening force of the
impact wrench. Compensate by fastening for a
longer period of time.

The manner of holding the tool or the material
of driving position to be fastened will affect the
torque.
Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
