# Preselecting the Impact Force

Note: Always test the selected impact force on a spare piece of material first. The optimal impact force setting can only be achieved through practice.

The figures in the table below are recommended values.

Various settings for the required impact force can be preselected with the thumbwheel (4) for impact force preselection.
When doing this, comply with the mark for preselection of impact force (3) on the power tool.

The impact force required depends on the length of the staples or nails and the strength of the material.

## Setting Range for Thumbwheel

Substrate |  |
Softwood (pine) | 1–4 | 4
Hardwood (beech) | 5–8 | 8
