Working Advice

The power tool with built-in Bluetooth^® Low Energy Module GCY 301‑42 is equipped with a radio interface.

When working, hold the power tool by the handle (1) with both hands. The handle (1) can move upwards and downwards around its axis. This has a damping effect against vibrations.

For the highest possible impact damping, work only with moderate pressure.

Sharpening Chisels

Only sharp chiselling tools will produce good results, therefore sharpen your chiselling tools in good time before use. This will ensure a long service life for the tools and good work results.

Resharpening

Grind chiselling tools against sanding discs, e.g. aluminium oxide, under a steady stream of water. Take care that no annealing colouration appears on the cutting edges; this impairs the hardness of the chiselling tools.

To forge a chisel, heat it to between 850 and 1050 °C (pale red to yellow).
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).
