Impacting techniques
The longer a bolt, screw or nut is impacted, the tighter it will become. To
prevent damage to the impact wrench, bit adapter or parts (screws, nuts),
avoid excessive screwing.
Mount different socket wrenches on the impact wrench and adjust the impact
duration and speed until you reach the desired level of tightness.
Traces of oil, dirt or dust on the screws or inside the socket wrenches can affect
the degree of tightness.
If you want to tighten a screw with a gasket, in order not to damage the gasket,
perform a light tightening with an impact wrench, then complete the tightening
with a hand torque wrench.
