8. Wear hearing protection to protect your ears 
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.
3. Appropriate safety glasses shall be used and 
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.
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, and secure the air 
hose to prevent danger if there is sudden jerking 
or catching.
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. Do not leave the loaded tool or the air com-
pressor under pressure for a long time out in 
the sun. Be sure that dust, sand, chips and 
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 y o, 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 shall adopt 
a suitable but ergonomic posture. Maintain 
secure footing and avoid awkward or o-bal-
anced postures.
3. If the operator experiences symptoms such 
as persistent or recurring discomfort, pain, 
throbbing, aching, tingling, numbness, burn-
ing sensation, or stiness, do not ignore these 
warning signs. The operator should consult a 
qualied 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 muscu-
lar-skeletal disorders and be preferentially based 
on the assumption that decreasing fatigue during 
work is eective 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 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.
4. Make sure there are no electrical cables, gas 
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
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 distur-
bance of dust in a dust lled 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, 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.
3. Appropriate controls to reduce the risk may 
include actions such as damping materials to 
prevent workpieces from "ringing".
4. Use appropriate hearing protection.
