Changing the Chiselling Position
The chisel can be locked in 12 positions. In this manner, the
optimum working position can be set for each application.
• Insert the chisel into the tool holder.
• Push the chisel adjustment ring 3 forward and turn the
chisel to the required position with the chisel adjustment
ring 3.
• Release the chisel adjustment ring 3 and turn the chisel
until it latches.

Working Advice

 Before any work on the machine itself, pull the
mains plug.
Sharpening Chisels
Good results are only achieved with sharp chisels; therefore,
sharpen the chiselling tools in good time. This ensures a long
service life of the tools and good working performance.
Re-sharpening
Sharpen chiselling tools using grinding wheels (e. g. ceramic
bonded corundum wheel) with a steady supply of water. Ref-
erence values are shown in the figure. Take care that no
annealing coloration appears on the cutting edges; this
impairs the hardness of the chiselling tools.
For forging, heat the chisel to between 850 and 1050 °C
(bright red to yellow).
For hardening, heat the chisel to approx. 900 °C and
quench in oil. Then anneal in an oven for approx. one hour at
320 °C (annealing colour = light blue).

Maintenance and Cleaning

 Before any work on the machine itself, pull the
mains plug.
 For safe and proper working, always keep the
machine and ventilation slots clean.
 A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
Service Indicator 6
When the carbon brushes are worn out, the machine switches
itself off. This is indicated approx. 8 hours beforehand by the
lighting or blinking of the service indicator 6. The machine
must then be sent to an after-sales service agent.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
a Würth master-Service.
In all correspondence and spare parts orders, please always
