in order to prevent unnecessary increase in noise. If the pneumatic tool has a muffl er, you should always make sure that it is
correctly mounted when you use the tool.
Risks of vibrations
Exposure to vibration may cause permanent damage to the nerves and blood supply to the hands and arms. 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 fi ngers 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 to avoid the unnecessary increase of vibration. Hold the tool, with light but a fi rm grip, taking into account the required
reaction forces, because the risk from vibration is ususally much larger, when the grip force is higher.
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 fi ttings. Cold air should be
directed away from the hands Every time when there are used universal screwed connections (claw couplings), you should apply
the protecting pins and connectors against the possibility of damage to the connections between the hoses and between the hose
and tool. Do not exceed the maximum air pressure specifi ed for the tool. Never carry the tool, by holding it by the hose.
OPERATING CONDITIONS
You should make sure that that the source of compressed air allows you to create the proper working pressure and that it provides
the required air fl ow. 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 fi lter and lubricator. This will ensure, at the same time, the air, which is pure and moistured
by oil. The state of the fi lter and lubricator should be checked before each use, and possibly clean the fi lter or refi ll shortage of oil
in the lubricator. This will ensure proper operation of the tool and will extend its service life.
In the case of high loads, there can be created a recoil force, which is directed towards the person, who is working with the tool.
You should adopt such an posture when you are working, to be able to eff ectively counter these forces.
Unexpected movement of the tool or rupture of inserted tool can cause injury.
If you use any additional handles or supporting racks, you should make sure, that the tool is mounted correctly and securely.
You should keep the body parts and clothing away from the working tool. There is a risk of being drawn or caught. You should
always make sure, that all keys and tools, which are used for adjustment and fastening of blades, have been removed before
you start work.
During work dust can develop, Depending on the workpiece it can be harmful for the operator.
During cutting or demolition works there may be thrown out elements of the workpiece.
Do not hold the inserted tool by unprotected hand. This may be the cause of an injury caused by vibrations.
USE OF THE PRODUCT
Before each use, you should check that none of the components of the product is damaged. If you notice any damage, you should
replace the element immediately with new one, undamaged system component.
Before each use of the the pneumatic system, you should dry the moisture condensed inside the tool, compressor and pipes.
Connecting the tool to pneumatic system
The fi gure shows the recommended connection of tool to the pneumatic system. Presented method will ensure the most effi cient
use of tool, and also it will extend the service life of the tool.
Let a few drops of oil with viscosity SAE 10 to the air intake.
To the thread of air inlet tightly and fi rmly screw the appropriate tip allowing for the connection of air supply hose. (II)
On the tool driver you should mount an appropriate tipl. When you work with pneumatic tools you should use only equipment
designed to work with the impact tools.
Speed / power of the tool can be adjusted by changing the air pressure for its powering. It is forbidden to excess the maximum
pressure, which is specifi ed in the table with technical data.
Connect the tool to air system using the hose with an inner diameter of 10 mm / 3/8 ". Make sure, that the strength of the hose is
at least 1.38 MPa. (III)
Start the tool for a few seconds, making sure that it does not issue any suspicious sounds or vibrations.
Preparation for tool operation
The cut material should be clamped in such a way, so it does not move during work. To do this, use clamps, grips or vises. If the
