appropriate for each use. Wear a protective helmet when working above the head. Risk to bystanders should also be taken into
account. Make sure that the workpiece is securely clamped.
Hazards connected with work
Using the tool can expose the operator’s hands to hazards such as cutting, abrasion and heat. Wear suitable gloves to protect
your hands. The operator and the maintenance personnel should be physically able to cope with the quantity, weight and power
of the tool. Hold the tool correctly. Be prepared to withstand normal or unexpected movements and always keep both hands at
the ready. Keep your feet in balance and in a safe position. The pressure on the start and stop device should be released in the
event of a power failure. Use only the lubricants recommended by the manufacturer. Avoid direct contact with the inserted tool
during and immediately after work, as it can be hot. The tool should not be used when pointed at the operator or any other person.
Keep your hands away from the compression mechanism; it is recommended that the operator hold the compression tool with
both hands. The compression mechanism and the yoke must be regularly checked for cracks. Hold the inserted tool fi rmly on the
work surface before starting the tool.
Fumes and dust hazards
The air outlet shall be so directed as to minimise the disruption of dust in a dusty environment.
Repetitive motions hazards
When using an assembly power tool for non-threaded mechanical fasteners, the operator can experience discomfort in the hands,
arms, shoulders, neck or other parts of the body. While using an assembly power tool for non-threaded mechanical fasteners, the
operator should adopt a comfortable posture whilst maintaining a secure footing and avoiding awkward or off -balance postures.
The operator should change posture during extended tasks; this 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 non-threaded mechanical fasteners from the energy supply before changing the inserted
tool or accessory. Use only sizes and types of accessories and consumables that are recommended by the manufacturer of as-
sembly power tools for non-threaded mechanical fasteners; do not use other types or sizes of accessories or consumables.
Workplace hazards
Slips, trips and falls are major causes of workplace injury. Be aware of slippery surfaces caused by use of the tool and also of trip
hazards caused by the air line or hydraulic hose. Proceed with care in unfamiliar surroundings. There can be hidden hazards,
such as electricity or other utility lines. The assembly power tool for non-threaded mechanical fasteners is not intended for use
in potentially explosive atmospheres and is not insulated against contact with electric power. Ensure that there are no electrical
cables, gas pipes, etc., which can cause a hazard if damaged by use of the tool.
Noise hazards
Exposure to high noise levels can cause permanent, disabling hearing loss and other problems, such as tinnitus (ringing, buzzing,
whistling or humming in the ears). Therefore, risk assessment and the implementation of appropriate controls for these hazards
are essential. Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from
“ringing”. Use hearing protection in accordance with employer’s instructions and as required by occupational health and safety
regulations. Operate and maintain the assembly power tool for non-threaded mechanical fasteners as recommended in the in-
struction handbook, to prevent an unnecessary increase in the noise level. Select, maintain and replace the consumable/inserted
tool as recommended in the instruction handbook, to prevent an unnecessary increase in noise. If the power tool has a silencer,
always ensure that it is in place and in good working order when the power tool is being operated.
Vibration hazards
Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms. Wear warm clothing
when working in cold conditions and keep your hands warm and dry. If you experience numbness, tingling, pain or whitening of
the skin in your fi ngers or hands, stop using the assembly power tool for non-threaded mechanical fasteners, tell your employer
and consult a physician. Support the weight of the tool in a stand, tensioner or balancer, because a lighter grip can then be used
to support the tool.
Additional safety instructions for pneumatic power tools
Air under pressure can cause severe injury:
- always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in
use, before changing accessories or when making repairs;
- never direct air at yourself or anyone else.
Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fi ttings. Cold air shall be directed away
from hands. Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whipcheck safety
