Safety precautions for vibration hazards
1. Exposure to vibration can cause disabling damage to
the nerves and blood supply of the hands and arms.
2. Keep the hands away from the sockets.
3. Wear warm clothing when working in cold conditions
and keep your hands warm and dry.
4. If you experience numbness, tingling, pain or
whitening of the skin in your fingers or hands, stop
using the assembly power tool for threaded fasteners,
tell your employer and consult a physician.
5. Operate and maintain the assembly power tool for
threaded fasteners as recommended in the instruction
handbook, to prevent an unnecessary increase in
vibration levels.
6. Do not use worn or ill-fitting sockets or extensions, as
this is likely to cause a substantial increase in
vibration.
7. Select, maintain and replace the consumable/inserted
tool as recommended in the instruction handbook, to
prevent an unnecessary increase in vibration levels.
8. Sleeve fittings should be used where practicable.
9. Support the weight of the tool in a stand, tensioner or
balancer, if possible.
10. Hold the tool with a light but safe grip, taking account
of the required hand reaction forces, because the risk
from vibration is generally greater when the grip force
is higher.
Additional safety instructions for pneumatic
power tools
1. Always shut of air supply, drain hose of air pressure
and disconnect tool from air supply when not in use,
before changing accessories or when making repairs.
2. Never direct air at yourself or anyone else.
3. Whipping hoses can cause severe injury. Always
check for damaged or loose hoses and fittings.
4. Cold air shall be directed away from the hands.
5. Do not use quick-disconnect couplings at tool inlet for
impact and air-hydraulic impulse wrenches. Use
hardened steel (or material with comparable shock
resistance) threaded hose fittings.
6. Whenever universal twist couplings (claw couplings)
are used, lock pins shall be installed and whip check
safety cables shall be used to safeguard against
possible hose-to-tool and hose-and hose connection
failure.
7. Do not exceed the maximum air pressure stated on
the tool.
8. For torque-control and continuous-rotation tools, the
air pressure has a safety critical effect on
performance. Therefore, requirements for length
and diameter of the hose shall be specified.
9. Never carry an air tool by the hose.
Warning
1. The tool shall not be used in explosive atmospheres
unless specially designed for that purpose.
2. The tool is not electrically insulated. Do not use
where there is a possibility of coming into contact
with live electricity.
3. Unexpected tool movement due to reaction forces or
breakage of inserted tool or reaction bar may cause
injuries.
4. Preferably shut off the air supply before changing
socket or at least ensure that the hands are well
clear of the operating trigger.
5. Be aware of the risk of crushing by torque between a
reaction bar and the workplace.
6. When loosening fasteners first ensure that there is
sufficient clearance behind the tool to avoid hand
entrapment. The tool will move away from the
threaded joint as the nut/bolt etc. Is loosened and
rides up the thread moving the tool with it.
7. There is a risk of being injured specially when
unscrewing in confined work place if hands are not
kept away from the reaction bar. Keep hands sway
from the nut runner socket.
8. In case of nut runner socket failure, it may danger to
person from high speed splinters being emitted fro
impact wrench.
9. Be aware of the whipping compressed air hose.
10. Always ensure that the reverse valves is in the
correct position before operating the tool. Do not run
the tool unless the socket is first located on the joint.
11. Prevent the loose clothes, long hair, or any other
personal accessories from closing to the moving
part to reduce the risk of being caught trapped or
drawn in the rotating spindle.
