When the carbon brushes wear below acceptable
service tolerances, the machine will automatically cut
out. The machine must be sent to customer service for
maintenance for address, see the "Service and Customer
Assistance" section.
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.
Reference 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. (Fig. 20).
For forging, heat the chisel to between 850ºC 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).
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should be
carried out by an after-sales service centre for Stayer
power tools.
In all correspondence and spare parts order, please
always include the article number given on the type plate
of the machine.
