Noise hazard
Exposure, without any protection, for high noise levels can cause permanent and irreversible hearing loss and other problems,
such as tinnitus (ringing, buzz, whistling or humming in the ears). It is necessary to perform the risk assessment and implement
appropriate control measures in relation to those risks. The appropriate checks, performed in order to reduce the risk, may include
activities such as: application of insulation materials to prevent the "ringing" of the workpiece. Use hearing protection in accord-
ance with the instructions of employer and in accordance with the requirements of hygiene and safety. Service and maintenance
of the pneumatic tool should be carried out according to the recommendations of the manual, to avoid the unnecessary increase
of noise level. If the pneumatic tool has a muffler, you should always make sure that it is correctly mounted when you use the
tool. Select, maintain and replace worn inserted tools according to the recommendations of the manual. This will allow to avoid
the unnecessary increase in noise.
Risks of vibrations
Exposure to vibration may cause permanent damage to the nerves and blood supply to the hands and arms. You should stay
away from the screw driver sockets. You should wear warm clothing when working at low temperatures and you should keep your
hands warm and dry. If you experience numbness, tingling, pain or skin whitening in the fingers and hands, you should discontinue
the use of pneumatic tool, and then inform your employer and seek medical advice. Operation and maintenance pneumatic tool
according to the recommendations of the manual, will allow avoid the unnecessary increase of vibration. Do not use worn or ill-
fitting caps, because it can cause a significant increase in the level of vibration. Select, maintain and replace worn inserted tools
according to the recommendations of the manual. It will allow to avoid the unnecessary increase of vibration. Where it is possible
the covering assembly should be used. If it is possible, you should subpart the weight of the tool in a rack, tensioner or equivalent.
Hold the tool, with light but a firm grip, taking into account the required reaction forces, because the risk from vibration is ususally
much larger, when the grip force is higher. An improperly mounted or damaged inserted tool can cause an increase in vibration.
Additional safety instructions for pneumatic tools
Air under pressure can cause serious injury:
- always shut off the air supply, drain hose of air pressure and detach tool from air supply, when it is not in use, before changing
accessories or performing repairs;
- never direct the air stream at yourself or anyone else.
Hose hitting can cause serious injury. You should always check for damaged or loose hoses and fittings. Cold air should be
directed away from the hands
Every time when there are used universal screwed connection (claw couplings), you should apply the protecting pins and connec-
tors against the possibility of damage to the connections between the hoses and between the hose and tool. Do not exceed the
maximum air pressure specified for the tool.
Never carry the tool, by holding it by the hose.
OPERATING CONDITIONS
You should also make sure that that the source of compressed air allows you to create the proper working pressure and that it
provides the required air flow. In the case of a too high air pressure, a reducer should be used together with a safety valve. The
pneumatic tool must be powered by the system of a filter and lubricator. This will ensure, at the same time, the air, which is pure
and moistured by oil. The state of the filter and lubricator should be checked before each use, and possibly clean the filter or refill
shortage of oil in the lubricator. This will ensure proper operation of the tool and will extend its service life.
If you use any additional handles or supporting racks, you should make sure, that the tool is mounted correctly and securely.
You should adopt an appropriate posture to counteract the normal or unexpected movement of the tool, caused by its torque.
Be careful of your work surroundings, the grinder machine can easily cut through something.
Do not use any grinding wheels and tools designed for grinding their surface side, for cutting.
Do not use any cutting discs or wheels for milling.
When you turn off the grinder, you should wait with its stacking, until a complete stop to the rotating tool.
Before the installation of additional equipment, you should make sure the maximum speed of the equipment is higher than the speed
of the grinder. Do not use any equipment with handles of other dimensions than those specified in the instructions. Do not modify the
grinding wheel mandrel to fit it to the diameter of the grip handle. Insert tool must be firmly and securely mounted in the tool holder.
Do not use reduction rings and sleeves, in order to match the diameter of the tool spindle and grinding wheel. Do not modify the
grinder holder to fit it to the mandrel diameter of the grinding wheel.
Abrasive element of the getting wheel should be stored and used in accordance with its manufacturer's instructions. Do not use
damaged equipment. Equipment with any faults must be replaced immediately to new and efficient. Check the status of the spindle
and tool holders for wear or damage.
Do not operate the grinder in a place with a high risk of explosion. The sparks, which are produced during operation, can cause a fire.
After mounting the grinding wheel you should run it for about 30 seconds in a safe position. Immediately stop the device, if you
observe a large vibration or other defects in the grinder behavior.
Any irregularities must be removed before the next launch of the grinder.
You should make sure that the grinding speed is not greater than the speed which is specified on the rating plate.
