3. If the operator experiences symptoms such as
persistent or recurring discomfort, pain,
throbbing, aching, tingling, numbness, burning
sensation, or stiffness, do not ignore these
warning signs. The operator should consult a
qualified health professional regarding overall
activities.
4. The continuous use of the tool may cause
repetitive strain injury due to recoil produced by
the tool.
5. To avoid repetitive strain injury, the operator
should not overreach or use excessive force.
Additionally, the operator should take a rest when
feeling fatigue.
6. Conduct a risk assessment regarding repetitive
motion hazards. It should focus on muscular-
skeletal disorders and be preferentially based on
the assumption that decreasing fatigue during
work is effective in reducing disorders.
Accessory and consumable hazards
1. Disconnect the energy supply to the tool, such as
air or gas or battery as applicable, before
changing/replacing accessories such as
workpiece contact, or making any adjustments.
2. Use only the sizes and types of accessories that
are provided by the manufacturer.
3. Use only lubricants recommended in this manual.
Workplace hazards
1. 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 hose.
2. Proceed with additional care in unfamiliar
surroundings. Hidden hazards may exist, such as
electricity or other utility lines.
3. This tool is not intended for use in potentially
explosive atmospheres and is not insulated from
coming into contact with electric power.
4. Make sure there are no electrical cables, gas pipes
etc. that could cause a hazard if damaged by use
of the tool.
5. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
6. There may be local regulations concerning noise
which must be complied with by keeping noise
levels within prescribed limits. In certain cases,
shutters should be used to contain noise.
Dust and exhaust hazards
1. Always check your surroundings. The air
exhausted from the tool may blow dust or objects
and hit operator and/or bystanders.
2. Direct the exhaust so as to minimize disturbance
of dust in a dust filled environment.
3. If dust or objects are emitted in the work area,
reduce the emission as much as possible to
reduce the health hazards and risk of injury.
Noise hazards
1. Unprotected 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).
2. Conduct a risk assessment regarding noise
hazards in the work area and implement
appropriate controls for these hazards.
3. Appropriate controls to reduce the risk may
include actions such as damping materials to
prevent workpieces from "ringing".
4. Use appropriate hearing protection.
5. Operate and maintain the tool as recommended in
these instructions, to prevent an unnecessary
increase in noise levels.
6. Take noise reduction measures, for example
placing workpieces on sound damping supports.
Vibration hazards
1. The vibration emission during operation depends
on the gripping force, the contact pressure force,
the working direction, the adjustment of energy
supply, the workpiece, the workpiece support.
Conduct a risk assessment regarding vibration
hazards and implement appropriate controls for
these hazards.
2. Exposure to vibration can cause disabling
damage to the nerves and blood supply of the
hands and arms.
3. Wear warm clothing when working in cold
conditions, keep your hands warm and dry.
4. If you experience numbness, tingling, pain or
whitening of the skin in your fingers or hands,
seek medical advice from a qualified occupational
health professional regarding overall activities.
5. Operate and maintain the tool as recommended in
these instructions, to prevent an unnecessary
increase in vibration levels.
6. Hold the tool with a light, but safe, grip because
the risk from vibration is generally greater when
the grip force is higher.
Additional warnings for pneumatic tools
1. Compressed air can cause severe injury.
2. Always shut off air supply, and disconnect tool
from air supply when not in use.
3. Always disconnect the tool from the compressed
air supply before changing accessories, making
adjustments and/or repairs, when moving away
from an operating area to a different area.
4. Keep fingers away from trigger when not
operating the tool and when moving from one
operating position to another.
5. Never direct compressed air at yourself or anyone
else.
6. Whipping hoses can cause severe injury. Always
check for damaged or loose hoses or fittings.
7. Never carry a pneumatic tool by its hose.
8. Never drag a pneumatic tool by its hose.
9. When using pneumatic tools, do not exceed the
maximum operating pressure ps max.
10. Pneumatic tools should only be powered by
compressed air at the lowest pressure required for
the work process to reduce noise and vibration,
and minimize wear.
11. Using oxygen or combustible gases for operating
pneumatic tools creates a fire and explosion
hazard.
12. Be careful when using pneumatic tools as the tool
could become cold, affecting grip and control.
