your footing if you drive fasteners while inching
backward. When driving fasteners against
perpendicular surface, work from the top to the
bottom. You can perform driving operations with less
fatigue by doing so.
11. A fastener will be bent or the tool can become
jammed if you mistakenly drive fastener on top of
another fastener or strike a knot in the wood. The
fastener may be thrown and hit someone, or the
tool itself can react dangerously. Place the
fasteners with care.
12. Never attempt to drive fasteners from both the
inside and outside at the same time. Fasteners may
rip through and/or fly off, presenting a grave danger.
Repetitive motions hazards
1. When using a tool for long periods, the operator
may experience discomfort in the hands, arms,
shoulders, neck, or other parts of the body.
2. While using a tool, the operator should adopt a
suitable but ergonomic posture. Maintain secure
footing and avoid awkward or off-balanced
postures.
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. Remove the gas container and battery 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 exhaust
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.
