Working with the jackhammer
1. If you wish to use the jack -
hammer at low temperatures or

operate for a few seconds
without an inserted tool. In this

better able to circulate inside the
jackhammer.

jackhammer with both hands on
the handles (1) and (4).
3. Exert only slight pressure on the
inserted tool.
The chiselling mechanism of the
jackhammer is activated when the
inserted tool is placed with slight
pressure onto the surface to be
processed.
