Makita GN420CLZK Instruction Manual page 8

5. The risks to others shall be assessed by the operator.
6. Be careful with tools without workpiece con-
tact as they can be fired unintentionally and
injure operator and/or bystander.
7. Ensure tool is always safely engaged on the
workpiece and cannot slip.
Wear hearing protection to protect your ears
8.
against exhaust noise and head protection.
Also wear light but not loose clothing. Sleeves
should be buttoned or rolled up. No necktie
should be worn.
Operating hazards
1. Hold the tool correctly: be ready to counteract
normal or sudden movements such as recoil.
2. Maintain a balanced body position and secure footing.
Appropriate safety glasses shall be used and
3.
appropriate gloves and protective clothing are
recommended.
4. Appropriate hearing protection shall be worn.
5. Use the correct energy supply as directed in
the instruction manual.
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.
Do not rush the job or force the tool. Handle
8.
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
fasteners as you move forward. It is easy to lose
your footing if you drive fasteners while inching
backward. When driving fasteners against perpen-
dicular 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 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
When using a tool for long periods, the oper-
1.
ator may experience discomfort in the hands,
arms, shoulders, neck, or other parts of the
body.
While using a tool, the operator should adopt
2.
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,
throbbing, aching, tingling, numbness, burn-
ing 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 repeti-
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.
Use only lubricants recommended in this
3.
manual.
Workplace hazards
Slips, trips and falls are major causes of work-
1.
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.
Proceed with additional care in unfamiliar
2.
surroundings. Hidden hazards may exist, such
as electricity or other utility lines.
This tool is not intended for use in potentially
3.
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.
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
Always check your surroundings. The exhaust
1.
from the tool may blow dust or objects and hit
operator and/or bystanders.
Direct the exhaust so as to minimize distur-
2.
bance 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
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).
Conduct a risk assessment regarding noise
2.
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.
