Air consumption depends heavily on the available pressures in the compressed air system, the air connections and the lines, the properties of the screw joint, and handling by the user.
For dimensioning of the pressure supply for compressed air tools, it is recommended to multiply the specified air consumption by 1.5, and for continuous operation / idling by 2.8.
The highest permissible continuous flow pressure / operating pressure directly at the machine should not exceed 6.2 bar / 90 psi. The flow pressure of 6.2 bar at the machine results from a
static pressure of 8 bar at the service device minus approx. 1.8 bar pressure loss in the connection lines of min. 8 mm inside diameter and couplings of min. 7 mm inside diameter.
The values shown were calculated under lab conditions, but are not sufficient for risk analyses. The actual values
may differ according to the actual conditions. The exact exposure and health risks for users will differ. Crucial factors
are work practices, the condition of the screw joint, and the duration of use.
Since the measured values of the actual exposure on site are beyond are control, AirApp Power Tools GmbH accepts
no liability for the consequences of any health risk.
This tool can trigger carpal tunnel syndrome if its use is not carefully controlled.

Maintenance
When servicing the impact wrench/ratchet, observe the environmental regulations under local law.
To achieve a longer lifetime, the manufacturer recommends annual professional maintenance by trained, qualified
personnel of your service partner.
If you have any questions, please contact the manufacturer.
Lubrication of the impact mechanism
Disconnect the impact wrench from the compressed air in order to prevent accidental activation.
The impact mechanism must be lubricated to ensure proper functioning of the mechanics.
1. Only use lubricating grease or oil approved by the manufacturer
2. Use a grease gun with the appropriate nozzle.
3. Before lubrication, remove external dirt.
The frequency of lubrication and quantity or lubricating grease or oil to be used depends on how the machine is used.
A need for maintenance is indicated by decreasing performance of the machine. Maintenance must be carried out no
later than that.
Lubrication of the motor
Disconnect the impact wrench from the compressed air in order to prevent accidental activation.
The motor requires lubrication to ensure proper functioning of the motor component group.
1. Use only mist lubricant approved by the manufacturer
2. Clean the air inlet of dirt before oiling
3. Insert mist lubricant (approx. 2 – 3 drops) into the air inlet, while keeping the trigger pressed
4. Allow the machine to idle briefly at the lowest power setting
Attention!
Maintenance of the impact wrench/ratchet may only be carried out by qualified personnel.
Repairs should only be carried out by the service partner of the manufacturer.
Disposal
When disposing of the device, comply with applicable local legislation. Remember that incorrect disposing of lubri-
cants causes environmental damage.
We accept no liability or warranty for damage or injuries resulting from improper use or misuse or failure to
comply with the safety information.
The device must only be used for the applications described.
Any other use is prohibited.
