Using the impact wrench
The impact wrench can be used for driving nuts and bolts using an impact socket and is suitable for many DIY applications.
Operating the Impact Wrench
Correct fastening torque may be determined by the kind of bolt, the size of the bolt or the material of the workpiece.
It is recommended that a test is performed prior to the final operation, in order to determine the fastening time for the nut or bolt you are using.
When using the impact wrench follow the below procedure: 1. Hold the tool pointed straight at the nut or bolt.
2.Depress the switch and fasten for the fastening time.
3.After fastening, always check the torque with a torque wrench.
Impact Time
Many variables exist that will cause the available torque of the fastener to vary considerably. The optimum impact time is approximately 6 seconds.
Note. Using an universal joint or extension bar may reduce the fastening force of the impact wrench and thus the application may require longer fastening time.
WARNING. The machine and the tool attachments may become warm when being used for a long time. If this occurs turn the machine off and place it in a safe environment and allow to cool down. Do not attempt to touch the metal blades after prolonged application as they will be hot and may burn. Do not overload the machine and always allow it to cool between the individual work steps.
WARNING. Wear safety goggles, a dust mask and ear defenders.
WARNING. Do not use the impact wrench in wet or damp conditions.
