for these risks. Appropriate control actions in order to reduce the risk
may include activities such as: the damping material to prevent „ring-
ing "of the workpiece, use of hearing protection equipment in accord-
ance with the instructions of the employer and in accordance with the
requirements of hygiene and safety. Operation and maintenance of
pneumatic tool should be carried out according to the instructions.
This will allow to avoid an unnecessary increase of noise level. If
the tool has pneumatic silencer, always be sure, that it is correctly
installed during use of the tool. Select, maintain and replace worn tool
which are implanted according to the instructions, this will allow to
avoid unnecessary increase in noise.
Vibration risks
exposure to vibration may cause permanent nerve damage and
blood supply to hands and arms. Keep hands away from screw-
drivers sockets. You should wear warm clothes during work at low
temperatures and keep your hands warm and dry. If you experience
numbness, tingling, pain, or skin whitening in the fi ngers and hands,
you should stop the use of pneumatic tool and then inform the em-
ployer and consult a doctor. Service and maintain the pneumatic tool
according to instructions will allow to avoid unnecessary increase in
the level of vibration. Keep the tool lightly, but securely, taking into
account the required reaction forces, because the threat from vibra-
tion is generally larger, when the grip force is stronger.
Additional safety instructions for pneumatic tool
Air under pressure may cause serious injuries:
- always cut off the air supply, drain hose of air pressure and dis-
connect the tool from the air supply, when: it is not used, before the
exchange of accessories or before the repairs;
- you should never direct air stream towards yourself or anyone else.
A stroke by the hose can cause serious injuries. You should always
check for damaged or loose hoses and couplings. Cold air should be
directed out of the hands. Every time when the universal screwed
connections are used (claw connection) you should use protective
mandrels and connectors, which are protecting against possible
damage of connections between hoses and between the hose and
tool. Do not exceed the maximum air pressure required for the tool.
Never transport the tool by holding its hose.

OPERATING CONDITIONS
Make sure that the compressed air source can generate appropriate
working pressure and that it ensures the required air fl ow. In the
case of excessive air pressure supply you should use reducer with
safety valve. Pneumatic tool should be fed by the system of fi lter and
lubricator. It will provide, at the same time, purity and air lubrication
by oil. Status of fi lter and lubricator should be checked before each
use and possibly clear the fi lter or complement defi ciency of oil in the
lubricator. This will ensure proper exploitation tool and will extend its
life span. Do not use tools and grinding wheels, which are designed
for cutting.
Do not use grinding wheels other than those, which are indicated in
the technical specifi cations.
Make sure that the maximum rotational speed of the disc is higher
than the speed of the grinder.
Semi-mounted sanding disks should be placed concentrically on the
pillow.
Wear safety goggles during the work, it is also recommended to use
gloves and protective clothing.
During some operations may arise poisonous or combustible dusts
and fumes. Work in a well ventilated area and use personal protec-
tion equipment.
TOOL USE
Before each use of the tool, make sure that no parts of the pneumat-
ic system are damaged. If you notice damage, immediately replace
the components with new, undamaged ones.
Dry condensed moisture inside the tool, compressor and hose be-
fore each use of the pneumatic system.
Preparing the tool for operation
Screw a suitable nozzle to the air inlet thread fi rmly and securely to
connect the air supply hose (II).
Before installing the blade, make sure that the permissible rotation
speed of the blade is equal to or higher than that of the grinder.
Mount the blade with the dimensions specifi ed in the technical data
table on the spindle. Screw the threaded axis of the blade into the
spindle hole. After tightening, insert the locking pin into the side hole
