- always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in use,
before changing accessories or when making repairs;
- never direct air at yourself or anyone else.
Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fi ttings. Cold air shall
be directed away from the hands. Do not use quick-disconnect couplings at tool inlet for impact and air-hydrau-
lic impulse wrenches. Use hardened steel (or material with comparable shock resistance) threaded hose fi t-
tings. Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whipcheck
safety cables shall be used to safeguard against possible hose-to-tool and hose-and-hose connection failure.
Do not exceed the maximum air pressure stated on the tool. For torque-control and continuous-rotation tools,
the air pressure has a safety critical eff ect on performance. Therefore, requirements for length and diameter
of the hose shall be specifi ed. Never carry an air tool by the hose.
CONDITIONS OF OPERATION
Make sure the source of compressed air may create appropriate working pressure and guarantee the required
fl ow of the air. If the pressure of the air is too high, use a reduced with a safety valve. The pneumatic tool must
be powered through a fi lter and a greaser.
It will guarantee simultaneously cleanliness and lubrication of the air with oil. The state of the fi lter and the
greaser must be checked before each use and, if necessary, the fi lter must be cleaned or the oil supplied in
the greaser. It will guarantee proper operation of the tool and will prolong its durability.
It is necessary to correctly adapt the reaction stick to a given task.
In the case additional holders or supporting stands are used; make sure the tool has been correctly fi xed.
Adopt a correct position that will allow you to react to normal or unexpected movements of the tool that may
be caused by the turning moment.
Do not keep hands or other parts of the body within the range of the reaction stick – it may lead to serious injuries.
Wrenches and other inserted tools must be adapted to work with pneumatic tools. The inserted tools must
be in good working order and must be cleaned and not damaged. Their size must fi t the dimensions of the
collector. It is prohibited to modify the sockets of the wrenches or the collector.
OPERATION OF THE TOOL
Before each use of the tool, make sure that no element of the pneumatic system is damaged. If there are any
damaged elements, they should be immediately replaced with new, faultless elements of the system.
Before each use of the pneumatic system, dry the humidity that condensates inside the tool, the compressor
and the dusts.
Connection of the tool to the pneumatic system
The drawing shows the recommended manner of connection of the tool to the pneumatic system. The pre-
sented connection guarantees the most eff ective operation of the tool and will prolong its durability.
Place a couple of drops of oil (of viscosity SAE 10) to the air inlet.
Into the thread of the air inlet, turn strongly an appropriate terminal that makes it possible to connect an air
supply hose. (II)
Install an appropriate terminal on the collector of the tool. During work with pneumatic tools, use solely the
equipment approved for work with percussive tools.
Adjust a correct direction of rotation. „F" indicates clockwise rotation, „R" – anticlockwise rotation.
Where it is possible, adjust the pressure (turning moment).
Connect the tool to the pneumatic system using a hose of internal diameter 3/8". Make sure the resistance of
the hose is at least 1.38MPa. (III)
