All servicing works and repairs may only be performed by authorised experts.
Power socket nuts to be used for impact wrenches only.
Never use any other types of socket nuts.
Never use power socket nuts with worn-out or knockedout driving square.
Before each use, check whether the driving square for power socket nuts and extension or spindle of the impact wrench  re not worn out or show any hairline crack. Before use, make sure the power socket nut is firmly fixed on the driving square of the appliance.
Make sure to use a compressor with a sufficient amount of supplied air (see Technical specifications).
Before each use, check whether the power control is set appropriately. Any incorrect setting may lead to screw connection breaking or tearing off and uncontrollable movement of the appliance.
Before putting the appliance into operation, make sure the switchover valve for right and left rotation is in the appropriate position.
Do not put the appliance into operation before the power socket nuts are firmly and properly fitted on the screw or nut head.
At regular intervals, check the pneumatic hose and all connections if not worn out.
Carry the appliance by the handle, not the hose. When doing so, your hand must not be near the operating button.
Do not try to hold or guide the appliance by the rotating power socket nuts.

The appliance is not grounded and insulated against electricity. In any case, do not use the appliance where there is a possibility of contact with electricity.
Make sure to prevent the rotating component of the appliance from getting near or in contact with free pieces of clothing, ties, hair, cleaning cloths, etc.
Provide sufficient space for backward movement when loosening the screw connections so that the operating hand could not get clinched as the tool is moving backward along the length of the thread with the impact wrench when the tool is being loosened.
Extensions, adapters and joints explicitly allowed to be used with the impact wrenches to be used only.
If the appliance shows any sign of irregular functioning when being used, it is necessary to immediately stop using it and have it serviced or repaired.
Disconnect the appliance from air supply if not being used. NEVER change any parts of the accessory equipment and do not perform ANY servicing work when the appliance is connected to air supply.
Do not damage the hoses and connections by carrying the appliance by the hose or by disconnecting the hose from air supply by pulling. Make sure to prevent the hose from
getting in contact with excess temperatures, oil and sharp edges. The hose needs to be replaced if damaged or worn out.
Air pressure when the appliance is being used MUST NOT exceed 6 bar. Use the pressure controller that will reduce the air pressure to 6 bar.
Make sure the speed of rotation of individual parts of the accessory equipment matches or exceeds the speed of rotation of the impact wrench.

Safety instructions for the operator

• Do not use the appliance before reading carefully the Operating Instructions.
• Follow all safety instructions given in the Operating Instructions.
• Behave responsibly to other persons.
• Walk, do not run when working.
• Use the right working clothes at all times.
• Provide good stability.

Operation

Safety notice!
Wear protective glasses! Wear ear protectors!
Before daily operation, please drain water from the compressor tank and blow out the condensate from the air hose at all times.
Now start the compressor. The maximum operating pressure of air is 6 bar.
The power (torque) of the impact wrenches under primary working conditions is especially determined by three aspects:
a) Operating pressure applied
b) Duration of work step on the screw connection. The normal working time for one screw connection is 3-5 seconds on average.
c) Setting of the switch lever in relation to the screw connection in proportion to the hammering time.
Due to the use of screws and materials of various hardness, there as increased friction, which brings a higher torque without a screw being tightened more firmly.
For rusty screw connections you should use an appropriate rust dissolving agent before using the impact wrench. If screw connections are still not loosened after 3-5 seconds of hammering, a one degree higher impact wrench needs to be used.
Do not overload the impact wrench to exceed the specified performance limit as this would drastically shorten the appliance life.
NOTE: The tightening torque on the screw connection is  directly connected with the screw firmness, appliance revolutions, conditions of the power socket keys used and time of using the impact wrench in the specific case of screwing. Use the most direct and easiest connection between the appliance and the power socket nut. Each extra connection and extension absorbs and reduces the appliance performance.
Picture B shows the setting of loosening torques.
Picture C shows the use of the impact wrench with a mist lubricator.

Servicing and treatment

CAUTION: Follow the maintenance instructions applicable to this appliance. Maintenance works not specified in this document must be performed by authorised servicing staff.

Lubrication

1. Disconnect the impact wrench from air supply.
2. Add 4-6 drops of GÜDE pneumatic oil, Art. No.40060 (we recommend the GÜDE mist lubricator, Art. No. 41354) or equivalent oil to the air inlet while the starter is being pressed.
3. Now reconnect the appliance to the air supply and let it run for app. 30 seconds to allow excessive oil to drain off.

This lubrication process contributes to the reduction of moisture, dust and dirt that get deposited in time in every compressor when using it and reduce its performance. The
best protection against deposition is offered by integrated oil tanks.
Every three months or when the impact wrench is in operation only occasionally you must remove the air hose and add more pneumatic oil to the air inlet. Then, refit the air
hose and let the impact wrench run for app. 30 seconds to allow the compressor engine to clean out. After cleaning, follow the lubrication instructions.

Troubleshooting

compressor
Impact wrench not working or working too slow| Insufficient air pressure| Check the air pressure on the air inlet. It must be 6 bar.
Air pressure set too low| Increase the pressure to 6 bar
Impact wrench must be lubricated with oil| See Lubrication
Impact wrench must be cleaned out| See Servicing
Air hose is leaking| Tighten all the hose screwing
