Diamond discs should only be used for cutting masonry/brick/concrete etc.- Cutoff discs are intended only for radial loading, i.e. for cutting.Do not grind with the sides of the cutting disc! This will break the disc (10)!CAUTION:Never change direction (turning radius less than 5 meters / 5 1/2 yards), exertlateral (sideways) pressure, or tip the Power Cutter during cutting (11)!- Use a cutting disc only for cutting the materials it is intended for. The proper typeof disc must be used, for either metals or masonry.- The arbour hole (bore) of the cutting disc must it the shaft exactly. If the arbourhole is larger than the shaft diameter, a spacer ring must be used (accessories).- Use only cutting wheels approved by the DSA (German Abrasive DiscCommittee) or equivalent organisation for freehand cutting at up to 4,370 RPM(= 80 m/sec. at circumference) for 14”/355 mm discs, or up to 5,100 RPM(= 80 m/sec. at circumference) for 12”/300 mm discs.- The disc must be free of defects (12). Do not use defective cutting discs.Always tighten the cutting disc mounting bolt to a torque of 30 Nm.Otherwise, the cutting disc can twist.- Before starting the cutting disc, make sure you have a steady footing.- Put the Power Cutter into operation only as described in this instruction manual(13).
