6. Do not use the tool on moving platforms or
back of trucks. Sudden movement of the platform
may lose control of the tool and cause injury.
7. Always assume that the tool contains fasteners.
8. Do not rush the job or force the tool. Handle
the tool carefully.
9. Watch your footing and maintain your balance
with the tool. Make sure there is no one below
when working in high locations.
10. On rooftops and other high locations, drive fas-
teners as you move forward. It is easy to lose your
footing if you drive fasteners while inching backward.
When driving fasteners against perpendicular sur-
face, work from the top to the bottom. You can per-
form driving operations with less fatigue by doing so.
A fastener will be bent or the tool can become
11.
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 danger-
ously. 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-bal-
anced postures.
3. If the operator experiences symptoms such as
persistent or recurring discomfort, pain, throb-
bing, aching, tingling, numbness, burning sen-
sation, or stiffness, do not ignore these warning
signs. The operator should consult a qualified
health professional regarding overall activities.
The continuous use of the tool may cause repeti-
4.
tive strain injury due to recoil produced by the tool.
To avoid repetitive strain injury, the operator
5.
should not overreach or use excessive force.
Additionally, the operator should take a rest
when feeling fatigue.
Conduct a risk assessment regarding repeti-
6.
tive motion hazards. It should focus on mus-
cular-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 work-
piece 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 work-
place injury. Be aware of slippery surfaces
caused by use of the tool and also of trip haz-
ards 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.
Make sure there are no electrical cables, gas
4.
pipes etc. that could cause a hazard if dam-
aged by use of the tool.
Keep work area clean and well lit. Cluttered or
5.
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 distur-
bance of dust in a dust filled environment.
If dust or objects are emitted in the work area,
3.
reduce the emission as much as possible to
reduce the health hazards and risk of injury.
Noise hazards
Unprotected exposure to high noise levels can
1.
cause permanent, disabling, hearing loss and
other problems such as tinnitus (ringing, buzz-
ing, whistling or humming in the ears).
2. Conduct a risk assessment regarding noise
hazards in the work area and implement appro-
priate controls for these hazards.
Appropriate controls to reduce the risk may
3.
include actions such as damping materials to
prevent workpieces from "ringing".
Use appropriate hearing protection.
4.
5. Operate and maintain the tool as recom-
mended 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 assess-
ment regarding vibration hazards and imple-
ment appropriate controls for these hazards.
2. 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
3.
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.
Operate and maintain the tool as recom-
5.
mended in these instructions, to prevent an
unnecessary increase in vibration levels.
Hold the tool with a light, but safe, grip
6.
because the risk from vibration is generally
greater when the grip force is higher.
