GENERAL SAFETY RULES
■
For multiple hazards, read and understand the safety
instructions before installing, operating, repairing,
maintaining, changing accessories on, or working
near the assembly power tool for threaded fasteners.
Failure to do so can result in serious bodily injury.
■
Only qualified 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. Modifications can reduce the effectiveness
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 manufacturer to obtain replacement
marking labels when necessary.
■
Ensure that the pressure of the air supply is not lower
than the lowest pressure specified by the manufacturer
for clutch-controlled assembly tools and make sure
that the air supply pressure does not fall after the
clutch has been set.
■
Support handle and reaction bar are not required for
this product.
PROJECTILE HAZARDS
■
Failure of the work piece, of accessories or even of
the inserted tool itself can generate high-velocity
projectiles.
■
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 work piece is securely fixed.
ENTANGLEMENT HAZARDS
■
Entanglement hazards can result in choking, scalping
and/or lacerations if loose clothing, personal jewelry,
neck ware, hair or gloves are not kept away from the
tool and accessories.
■
Gloves can become entangled with the rotating drive,
causing severed or broken fingers.
■
Rotating drive sockets and drive extensions can easily
entangle rubber-coated or metal-reinforced gloves.
■
Do not wear loose-fitting gloves or gloves with cut or
frayed fingers.
■
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
abrasions and heat. Wear suitable gloves to protect
hands.
■
Operators and maintenance personnel shall be
physically 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 straight case and pistol-
grip tools. Reaction bars are recommended for angle
nut runners. 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 nut runners.
■
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 nut
runners.
■
Do not use in confined spaces and beware of crushing
hands between tool and work piece, especially when
unscrewing.
REPETITIVE MOTIONS HAZARDS
■
When using an assembly power tool for threaded
fasteners to perform work-related activities, 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 while 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
stiffness, these warning signs should not be ignored.
The operator should tell the employer and consult a
qualified health professional.
ACCESSORY HAZARDS
■
Disconnect the assembly power tool for threaded
fasteners from the energy supply before changing the
inserted tool or accessory.
■
Do not touch sockets or accessories during impacting,
as this increases the risk of cuts, burns or vibration
injuries.
■
Use only sizes and types of accessories and
