eliminate the vibrations which remain as residual risks. Improper use of the tool may result in exposure to vibration. The value of
the vibrations specifi ed in the manual may not adequately represent the vibration level of the intended use. Exposure to vibration
can cause permanent damage to the nerves and blood supply of the hands and arms. Wear warm clothes when working at low
temperatures and keep your hands warm and dry. If numbness, tingling, pain or bleaching occurs in your fi ngers or hands, stop
using the pneumatic tool, then inform your employer and consult your doctor. The operation and maintenance of the pneumatic
tool in accordance with the operating instructions will prevent unnecessary increases in vibration levels. Do not hold the tool with
your free hand, this increases the exposure to vibrations. Hold the tool with a light but secure grip, taking into account the required
reaction forces, as the risk of vibration is usually higher when the clamping force is higher. Hold the additional handles in a central
position and avoid pressure on the handle until the device stops. In the case of crushers, remove smaller pieces of concrete to
prevent the tool from jamming. In the case of crushers, move the tool every few seconds. The tool must be stopped during moving
because vibrations reach a high level if the inserted tool is not supported by the workpiece.
Additional safety instructions for pneumatic tools
Pressurised air can cause serious injury:
- always disconnect the air supply, release the air pressure from the hose and disconnect the tool from the air supply when not in
use, before changing accessories or carrying out repairs;
- never point the air stream at yourself or anyone else.
Hitting with the hose can cause serious injury. Always check for damaged or loose hoses and connectors. Keep cold air away
from hands.
Whenever universal screwed connections (dog connections) are used, safety pins and safety connectors must be used to prevent
damage to the connections 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 while holding the hose.

OPERATING CONDITIONS

Make sure that the compressed air source generates the correct working pressure and provides the required airfl ow. If the supply
air pressure is too high, a pressure reducer with a safety valve must be used. The pneumatic tool must be fed through the fi lter and
lubricator system. This will ensure that the air is both clean and moistened with oil. Check the condition of the fi lter and lubricator
before each use and clean the fi lter if necessary or make up for oil shortage in the lubricator. This will ensure the correct operation
of the tool and extend its service life.
In the case of heavy loads, a recoil force may be generated towards the tool operator. It is necessary to adopt such a posture
during work to be able to counteract these forces eff ectively.
If you move the tool unexpectedly or break the inserted tool, you may be injured.
When using additional holders or support racks, make sure that the tool is correctly and securely attached.
Keep body parts and clothing away from the working tool. There is a risk of being pulled in or caught. Always make sure that all
keys and tools used for adjusting and attaching other tools to the pneumatic scaler are removed before starting work.
During operation, dust can be generated which, depending on the workpiece, can be harmful to the operator.
During cutting or demolition work, workpiece elements can be ejected.
Do not hold the inserted tool with an unprotected hand. This can cause injuries due to vibration.
TOOL USE
Before each use of the tool, make sure that no parts of the pneumatic system are damaged. If you notice damage, immediately
replace the components with new, undamaged ones.
Dry condensed moisture inside the tool, compressor and hose before each use of the pneumatic system.
Connecting the tool to the pneumatic system
The fi gure shows the recommended way to connect the tool to the pneumatic system. This will ensure the most effi cient use of
the tool and also prolong the tool's service life.
Apply a few drops of SAE 10 viscous oil into the air inlet.
Screw a suitable nozzle to the air inlet thread fi rmly and securely to connect the air hose (II).
Secure a suitable nozzle to the tool driver. Only use accessories which are suitable for use with impact tools when working
with pneumatic tools.
Set the correct direction of rotation. The letter F stands for clockwise rotation and the letter R for counter-clockwise movement.
Wherever possible, adjust the pressure (torque).
Connect the tool to the pneumatic system using a hose with an internal diameter of 10 / 3/8". Make sure the hose has a strength
of at least 1.38 MPa. (III)
Start the tool for a few seconds, making sure that there are no suspicious sounds or vibrations.
