  • Recommended maximum bolt size: M16

  • Impact screwdrivers are not torque screwdrivers. Connections requiring a specific torque must be checked by means of a torque measuring device after tightening with the impact screwdriver.

  • The operating torque is the torque usually achieved under average working conditions. It depends on the highly varying ambient conditions (air pressure, hose diameter, soiling etc.).

  • When the impact screwdriver is used regularly (e.g. for tyre maintenance), a little oil should be added daily, and approximately 2 strokes of gear grease should be added monthly via the grease nipple.

  • Plug-in nipple not included in the scope of delivery
