5.) Stroke rate control (Fig. 2)
The jigsaw is equipped with a stroke rate control. By turning the button
the stroke rate can be changed continuously:
From setting 1
Through setting 6
The most suitable stroke rate depends on the material and on the saw
blade and can be determined by practical testing on a piece of clipping.
Material
Soft wood
Hard wood
Soft metals (aluminium)
Steel
Plastics
6.) Orbital cut adjustment (Fig.3)
The orbital cut causes the saw blade to cut itself free better, thus
allowing faster work. The cleaner the cutting edge is meant to be the
lower an orbital setting should be chosen. Determine the optimum
setting by test cutting an off-cut you will not need again.
Setting 0 - no orbital cut for thin material and clean cutting edges
Setting I - slight orbital cut for hard material (metal)
Setting II - medium orbital cut for thicker material
Setting III - strong orbital cut for fast work
