Working Advice
Sharpening Chisels
Only sharp chiselling tools will produce good results, there-
fore sharpen your chiselling tools in good time before use.
This will ensure a long service life for the tools and good
work results.
Re-sharpening
Grind chiselling tools against sanding discs, e.g. aluminium
oxide, under a steady stream of water. Make sure that the
cutting edges show no annealing colours; this will impair the
hardness of the chiselling tools.
To forge a chisel, heat it to 850–1050 °C (pale red to yel-
low).
To harden a chisel, heat it to approx. 900 °C and quench in
oil. Then, leave it in an oven for approx. one hour at 320 °C
(annealing colour: pale blue).
Vibration damping
The integrated vibration damping function re-
duces the generated vibration.
Do not continue to use the power tool if the damping
u
element is damaged.

hand by the service indicator (4) lighting up or flickering.
