Working Advice
The power tool with built-in Bluetooth
u
Module GCY 301‑42 is equipped with a radio inter-
face.
When working, hold the power tool by the handle (1) with
both hands. The handle (1) can move upwards and down-
wards around its axis. This has a damping effect against vi-
brations.
For the highest possible impact damping, work only with
moderate pressure.
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.
Resharpening
Grind chiselling tools against sanding discs, e.g. aluminium
oxide, under a steady stream of water. Take care that no an-
nealing colouration appears on the cutting edges; this im-
pairs 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).
