act typical or sudden movements – keep both hands
ready.
• Be sure your body is well balanced and maintain a
solid stance.
• If tools are required to absorb the reaction torque,
use a suspension attachment whenever possible. If
this is not possible, we recommend side handles for
machines with straight handle and pistol grip. At any
rate we recommend using tools to absorb if it is gre-
ater than 4 Nm for machines with straight handles,
greater than 10 Nm for machines with pistol grip and
greater than 60 Nm for offset screwdrivers.
• In the event of power failure release the startor stop
control.
• Only use the lubricants recommended by the manu-
facturer.
• Hex nut drivers with open flathead can crush fingers.
• Do not use the tool in tight spaces and be sure your
hands are not crushed between the machine and
work piece, especially when unscrewing.
Hazards due to repetitive motions
• When using a machine for screw connections the
operator may experience discomfort in hands, arms,
shoulders, neck or other body parts whilst perfor-
ming work-related tasks.
• Maintain a comfortable position whilst using this
tool, be mindful of a secure grip and avoid awkward
positions or positions making it difficult to maintain
your balance. The operator should change his pos-
ture during extended periods of use, which may help
to prevent discomfort and fatigue.
• If the operator experiences symptoms such as per-
sistent malaise, discomfort, palpitations, pain, ting-
ling, numbness, a burning sensation or stiffness,
these warning signs should not be ignored. The user
should consult a qualified healthcare professional.
Risks associated with accessories
• Disconnect machine from the power supply before
changing a tool or accessory.
• Do not touch collets or accessories whilst impact
driving, as doing so may increase the risk of cuts,
burns or injuries from vibration.
• Only use the size and types of accessories and con-
sumables recommended by the manufacturer of the
machine.
• Only use impact sockets in good working condition
as manual sockets and accessories in poor working
condition may break and be ejected when used with
impact drivers.
Hazards in the work environment
• Slipping, tripping and falls are main causes of inju-
ries at the workplace. Be mindful of surfaces which
may have become slippery during machine use, and
of tripping hazards caused by the air- or hydraulic
hose.
• Proceed with caution in unfamiliar surroundings.
These may hold hidden dangers due to electrical
cables or supply lines.
• The machine for screw connections is not suitable
for use in explosive environments and is not insula-
ted against contact with electrical power sources.
• Verify there are no electrical lines, gas lines, etc.
which may result in a hazard in the event they are
damaged during machine use.
Hazards due to dust and vapours
• Dusts and vapours generated by use of machines
for screw connections may result in damage to the
health (e.g. cancer, birth defects, asthma and / or
dermatitis); it is imperative to perform a risk assess-

ment for these hazards and implement the respecti-
ve regulatory mechanisms.
• The risk assessment should include dust genera-
ted from machine use and dust in the area possibly
being blown around.
• Exhaust air must be discharged so the amount of
dust being blown about in a dusty environment is
minimised.
• If dust or vapours are generated the principal task
must be to monitor them in the area where they are
released.
• All machine mounting parts or accessories intended
to collect, extract or eliminate airborne dust or va-
pours should be used and maintained according to
manufacturer instructions.
• Use respiratory protection.
Noise hazards
• With inadequate ear protectors the impact of high
noise levels may result in permanent hearing dama-
ge, hearing loss and other problems, e.g. tinnitus
(ringing, whistling or buzzing in the ear).
• It's imperative to perform a risk assessment for the-
se hazards and implement the suitable regulatory
mechanisms.
• Suitable regulatory mechanisms to minimise the risk
include measures such as using insulation to pre-
vent pinging sounds on work pieces.
• Use hearing protection.
• The machine for screw connections must be opera-
ted and maintained as recommended in these inst-
ructions to prevent an unnecessary increase in the
noise level.
• If the machine for screw connections features a si-
lencer, always ensure it is available when using the
machine for screw connections and in good working
order.
• Select, maintain and replace consumables and ma-
chine tools as recommended in these instructions to
prevent an unnecessary increase in the sound level.
Hazard due to vibration
• Exposure to vibration may cause damage to the ner-
ves and disturb blood circulation in hands and arms.
• Keeps hands away from the sockets of hex nut dri-
vers.
• Wear warm clothes when working in cold environ-
ments and keep hands warm and dry.
• If you notice your skin on fingers or hands becoming
numb, tingling, hurting or becoming white, stop wor-
king with the machine and consult a physician.
• Operate and maintain the machine for screw con-
nections as recommended in this manual to prevent
an unnecessary increase in vibration.
• Do not use work or poorly fitting sockets or extensi-
ons, as these are very likely to significantly increase
vibration.
• Select, maintain and replace consumables and ma-
chine tools as recommended in these instructions to
prevent an unnecessary increase in vibration.
• When possible use socket fittings.
• Whenever possible, use a stand, clamp or an equali-
ser to support the weight of the machine.
• Do not grip the machine too tightly but firmly, main-
taining the necessary hand reaction forces, as the
vibration hazard typically increases when tightening
the grip.
Additional safety instructions for pneumatic ma-
chinery
• Compressed air can result in serious injuries.
- Always close the air supply, release pressure from
the hose, and disconnect the machine from the com-
