General safety rules
For multiple hazards, read and understand the safety instructions before installing, operating, repairing, main-
taining, changing accessories on, or working near the assembly power tool for threaded fasteners. Failure to
do so can result in serious bodily injury. Only qualifi ed and trained operators should install, adjust or use the
assembly power tool for threaded fasteners. Do not modify this assembly power tool for threaded fasteners.
Modifi cations can reduce the eff ectiveness of safety measures and increase the risks to the operator. Do not
discard the safety instructions; give them to the operator. Do not use the assembly power tool for threaded
fasteners if it has been damaged. Tools shall be inspected periodically to verify that the ratings and markings
required by this part of ISO 11148 are legibly marked on the tool. The employer/user shall contact the manu-
facturer to obtain replacement marking labels when necessary.
Projectile hazards
Failure of the workpiece, of accessories or even of the inserted tool itself can generate high-velocity projec-
tiles. Always wear impact-resistant eye protection during the operation of the assembly power tool for threaded
fasteners. The grade of protection required should be assessed for each use. Ensure that the workpiece is
securely fi xed.
Entanglement hazards
Entanglement hazards can result in choking, scalping and/or lacerations if loose clothing, personal jewellery,
neckware, hair or gloves are not kept away from the tool and accessories. Gloves can become entangled with
the rotating drive, causing severed or broken fi ngers. Rotating drive sockets and drive extensions can easily
entangle rubber-coated or metal-reinforced gloves. Do not wear loose-fi tting gloves or gloves with cut or frayed
fi ngers. Never hold the drive, socket or drive extension. Keep hands away from rotating drives.
Operating hazards
The use of the tool can expose the operator's hands to hazards including crushing, impacts, cuts and abra-
sions and heat. Wear suitable gloves to protect hands. Operators and maintenance personnel shall be physi-
cally able to handle the bulk, weight and power of the tool. Hold the tool correctly; be ready to counteract
normal or sudden movements and have both hands available. 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 absorb 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 manufacturer. Fingers can be crushed in open-
ended crow-foot nutrunners. Do not use in confi ned 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, shoulders, neck, or
other parts of the body. While using an assembly power tool for threaded fasteners, the operator should adopt
a comfortable posture whilst maintaining secure footing and avoiding awkward or off -balanced postures. The
operator should change posture during extended 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 stiff ness, these warning signs should not be ignored. The operator should
tell the employer and consult a qualifi ed health professional.
Accessory hazards
Disconnect the assembly power tool for threaded fasteners from the energy supply before changing the insert-
ed tool or accessory. Do not touch sockets or accessories during impacting, as this increases the risk of cuts,
