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 thoroughly read and completely
understood this Instruction Manual and the enclosed “General
Safety Instructions” (document number 3 41 30 465 06 0). 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 unscrewing 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.
Use ear protection during operation.
Wear personal protective equipment. Depending on application, 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 operation. 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 work materials containing magnesium. Danger of fire.
Do not work CFP (carbon-fiber-reinforced polymer) and materials containing
asbestos. These materials are considered carcinogenic.
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 manufacturer.
Safe operation is not ensured merely because an accessory fits your power
tool.
Ensure that the accessory is securely fastened each time before using. When
using a square drive with drill hole, the accessory must additionally be
positively locked. Loose or not securely fastened accessories can become loose
or be thrown off.
Clean the ventilation openings on the power tool at regular intervals using
non-metal tools. The blower of the motor draws dust into the housing. An
excessive accumulation of metallic dust can cause an electrical hazard.
Never look or stare into the light of the power tool’s lamp from a short
distance. Never point the light of the lamp into the eyes of other persons in
close vicinity.
The radiation produced by the lamp can be harmful for the eye.
Do not direct the power tool against yourself, other persons or animals.
Danger of injury from sharp or hot application tools.
Switch the power tool off immediately when the application tool blocks. Do not
switch the power tool on again while the application tool is blocked; this
could lead to kickback with high reaction torque. Determine and correct the
cause of the blockage of the application tool, taking the safety warnings into
account. Possible causes could be:
- Jamming in the workpiece
- Breaking through the material being worked
- Overloading the power tool.
INSTRUCTION
Use and handling of the battery (battery pack).
To avoid hazardous situations such as burns, fire, explosion, skin injuries,
and other injuries when handling the battery, observe the following
instructions:
Batteries must not be disassembled, opened or reduced in size. Do not subject
batteries to mechanical impact or shock. Hazardous vapours and fluid can
escape in case of damage and improper use of the battery. The vapours can
irritate the respiratory system. Liquid ejected from the battery may cause
skin irritations or burns.
When battery fluid from a damaged battery has come into contact with objects
close by, check the respective components, clean them or replace them as
required.
Keep the battery away from heat and fire. Do not store the battery in direct
sunlight.
Do not remove the battery from its original packaging until it is going to be
used.
Before any work on the machine itself, remove the battery from the power tool.
If the power tool accidentally starts, there is danger of injury.
Mount the battery only when the power tool is switched off.
Remove the battery only when the power tool is switched off.
Keep the battery away from children.
Keep the battery clean and protect it against moisture and water. Clean
contaminated battery terminals and power tool connections with a dry, clean
cloth.
Use only intact original FEIN batteries that are intended for your power tool.
When working with and charging incorrect, damaged, repaired or reconditioned
batteries, imitations or other brands, there is danger of fire and/or
explosion.
Follow the safety warnings in the operating instructions of the battery
charger.
Hand/arm vibrations
The vibration emission level given in this information sheet has been measured
in accordance with a standardised test given in EN 62841 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, organisation of work patterns.
Handling hazardous dusts
For work procedures with this power tool where material is removed, dusts
develop that can be hazardous to one’s health.
Contact with or inhaling some dust types, e. g. asbestos and asbestos-
containing materials, lead-containing coatings, metal, some wood types,
minerals, silicate particles from materials containing stone, paint solvents,
wood preservatives, antifouling paints for vessels, can trigger allergic
reactions to the operator or bystanders and/or lead to respiratory infections,
cancer, birth defects or other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched appropriately for the
developing dust, as well as personal protective equipment and provide for good
ventilation of the workplace. Leave the processing of asbestos-containing
materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust and chemical
materials can self-ignite under unfavourable conditions or cause an explosion.
Avoid sparking in the direction of the dust collector as well as overheating
of the power tool and the materials being sanded, empty the dust
collector/container in time,observe the material manufacturer’s working
instructions, as well as the relevant regulations in your country for the
materials being worked.
Operating Instructions
Adjust the rotation selector switch only when the machine is at a complete
stop.
Thermal overload of the power tool is indicated through flashing of the LED in
the handle.
In case of overload, the machine switches off.
Danger of burning. The application tool can become hot during operation.
Allow the application tool to cool down:
- after placing the power tool down
- prior to tool changing.
To avoid accidental starting, e. g., during transport, set the rotation
selector switch to the centre position.
Apply the power tool to the nut or screw only when switched off, as a rotating
application tool could slip off.
Hold the power tool perpendicular to the screw at an angle of 90° when
screwing in and unscrewing.
If the power tool is applied inclined, the screw head can be damaged and the
force is not transferred to the screw.
An unnecessary long impact period increases the wear of the power tool.
Determine the impact duration for the respective screwdriving application and
check the actually reached tightening torque with a torque wrench.
Orientation values for the impact duration are shown in the diagram on page
13.
