For your safety.
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future reference.
Do not use this power tool before you have thor-
oughly read and completely understood this
Instruction Manual and the enclosed “General
Safety Instructions” (document number
3 41 30 054 06 1). The documents mentioned should be
kept for later use and enclosed with the power tool,
should it be passed on or sold.
Please also observe the relevant national industrial safety
regulations.
Intended use of the power tool:
Hand-held impact wrench for screwing in and unscrew-
ing screws and nuts in weather-protected environments
without water supply using the application tools and
accessories recommended by FEIN.
Special safety instructions.
Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may contact
hidden wiring. Fasteners contacting a “live” wire may
make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e.g. with a metal detector.
Wear personal protective equipment. Depending on appli-
cation, use face shield, safety goggles or safety glasses.
Where appropriate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stopping small
abrasive or workpiece fragments. The eye protection
must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be
capable of filtrating particles generated by your opera-
tion. Prolonged exposure to high intensity noise may
cause hearing loss.
Secure the work piece firmly. A work piece that is
gripped tightly in a clamping device or vice, is more
secure than if held by hand.
Hold the power tool firmly. High reaction torque can
briefly occur.
Do not machine any material containing asbestos. Asbes-
tos is cancerogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Do not use accessories which are not specifically
designed and recommended by the power tool manufac-
turer. Safe operation is not ensured merely because an
accessory fits your power tool.
Clean the ventilation openings on the power tool at regu-
lar intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
