General safety rules
Maintain a balanced body position and secure
footing.
In cases where the means to absorb the reaction
torque are requested, it is recommended to use
a suspension arm whenever possible. If that is
not possible, side handles are recommended for
straightcase and pistol-grip tools. Reaction bars
are recommended for angle nutrunners. In any
case, it is recommended to use a means to ab-
sorb the reaction torque above 4 Nm for straight
tools, above 10 Nm for pistol-grip tools, and
above 60 Nm for angle nutrunners.
Release the start-and-stop device in the case of
an interruption of the energy supply.
Use only lubricants recommended by the manu-
facturer.
Fingers can be crushed in open-ended crow-foot
nutrunners.
Do not use in confined spaces and beware of
crushing hands between tool and workpiece,
especially when unscrewing.
Repetitive motions hazards
When using a power tool for, the operator can
experience discomfort in the hands, arms, shoul-
ders, neck, or other parts of the body.
While using an assembly power tool for threaded
fasteners, the operator should adopt a comfort-
able posture while maintaining secure footing
and avoiding awkward or off-balanced postures.
The operator should change posture during ex-
tended tasks, which can help avoid discomfort
and fatigue.
If the operator experiences symptoms such as
persistent or recurring discomfort, pain, throbbing,
aching, tingling, numbness, burning sensations
or stiffness, these warning signs should not be
ignored. The operator should consult a quali-
tied health professional.
Accessory hazards
Disconnect the assembly power tool for threaded
fasteners from the energy supply before chang-
ing the inserted tool or accessory.
Do not touch sockets or accessories during im-
pacting, as this increases the risk of cuts, burns
or vibration injuries.
Use only sizes and types of accessories and con-
sumables that are recommended by the assembly
power tool for threaded fasteners manufacturer;
do not use other types or sizes of accessories
and consumables.
Use only impact-wrench-rated sockets in good
condition, as poor condition or hand sockets
and accessories used with impact wrenches
can shatter and become a projectile.
Workplace hazards
Slips, trips and falls are major causes of work-
place injury. Be aware of slippery surfaces caused
by the use of the tool and also of trip hazards
caused by the air line or hydraulic hose.
Proceed with care in unfamiliar surroundings.
Hidden hazards, such as electricity or other util-
ity lines, can exist.
The assembly power tool for threaded fasteners
is not intended for use in potentially explosive
atmospheres and is not insulated against com-
ing into contact with electric power.
Make sure there are no electrical cables, gas
pipes, etc., that can cause a hazard if damaged
by use of the tool.
Dust and fume hazards
Dust and fumes generated when using assembly
power tools for threaded fasteners can cause
ill health (for example cancer, birth defects,
asthma and / or dermatitis); risk assessment and
implementation of appropriate controls for these
hazards are essential.
Risk assessment should include dust created by
the use of the tool and the potential for disturb-
ing existing dust.
Direct the exhaust so as to minimize disturbance
of dust in a dust-filled environment.
Where dust or fumes are created, the priority
shall be to control them at the point of emission.
