hands warm and dry. In case of numbness, tingling, pain or whitening of the skin in the fi ngers and hands, it's necessary to stop
using the pneumatic tool, then inform the employer and consult a doctor. The service and maintenance of the pneumatic tool
should be carried out in accordance with the user manual, will allow to avoid an unnecessary increase of vibration level. Do not
hold an insertion tool with your free hand, this increases the vibration exposure. Hold the tool with a light but fi rm grip, taking into
account the required reaction forces, because the risk from vibrations is usually greater when the grip strength is higher. Keep the
additional holders from the central position and avoid pressing the holder until it stops. In case of the crushers, remove smaller
pieces of concrete to prevent wedging of the tool.. In case of the crushers, move the tool every few seconds. During movement,
the tool must be stopped because vibrations reach a high level if an insertion tool does not overlap the workpiece.
Additional safety instructions for pneumatic tools
Air under pressure can cause serious injury:
- always cut off the air supply, empty the hose from the air pressure and disconnect the tool from the air supply when: it is not used,
before changing accessories or while performing repairs;
- never point an air stream at yourself or anyone else.
Hit by hose can cause serious injury. Always check the hoses and fi ttings for wear and or damage, for any leakes. Cold air should
be pointed away from the hands.
Whenever universal screw connections i.e. twist coupling are used (claw couplings), safety pins and safety connectors must be
used to prevent damage to the connectors between the hoses and between the hose and the tool. Do not exceed the maximum
air pressure specifi ed for the tool.
Never carry the tool by holding the hose.

OPERATING CONDITIONS

It's necessary to ensure that, the source of compressed air allows to create the proper working pressure and it provides the re-
quired 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 fi lter system and lubricator.
It will ensure, at the same time, the air which is pure and moistured by oil. The condition of the fi lter and lubricator should be
checked before each use, and possibly clean the fi lter or to top up the shortage of oil in the lubricator. It will ensure proper opera-
tion of the tool and will extend its normal service life.
In case of heavy loads always use an additional holder.
If the drill stops, for example due to jamming or when passing through the material being drilled, large rotational forces acting on
the tool can be triggered. It's necessary to adopt such a posture, to be able to eff ectively counteract such forces.
An unexpected tool movement or breaking of the drill may cause injuries.
In case of the using additional holders or supporting stands, ensure that the tool is correctly and securely fastened.
It's necessary to adopt such a posture, which will allow eff ectively counteract the normal or unexpected movement of the tool
caused by the torque.
Keep body parts and clothes away from the rotating holder and drill. There is a risk of being drawn or caught. Always ensure that
all keys and tools used to adjust and assemble other insertion tools in the drill have been removed before drilling.

USE OF THE TOOL

Before each use of the tool, ensure that no parts of the pneumatic system are damaged. If any damage is observed, immediately
replace it with new undamaged system components.
Before each use of the the pneumatic system, you should dry the condensed moisture inside the tool, compressor and other parts.
Connecting the tool to pneumatic system
The fi gure shows the recommended method of connecting of the tool to the pneumatic system. The method shown will ensure the
most eff ective use of the tool and will extend the its normal service life.
Let a few drops of oil with viscosity SAE 10 into the air inlet.
To the air inlet thread securely and fi rmly tighten screw an appropriate bit to connect the air hose. (II)
On the tool driver mount an appropriate bit. While working with pneumatic tools it should be used only equipment designed
to work with the impact tools.
There, where it's possible, adjust the pressure (torque).
Connect the tool to pneumatic system using the hose with an inner diameter of 10 mm / 3/8". Ensure that the hose has a strength
of at least 1,38MPa. (III)
Start the tool for a few seconds making sure that no suspicious sounds or vibrations come from it.
Fixing the drill in the holder (IV)
Select a drill with roller grip proper for specifi c job. Insert the drill bit into the chuck and then holding the back of the chuck rotate
the front part of the chuck, so that the drill is fi xed in the chuck tightly and reliably.
