Manual De - Makita AN454 Instruction Manual

foreign matter will not enter the tool in the
place where you leave it setting.
13. 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. 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.
