6Cutoff discs- The protection hood must always be on! Change discs onlywith the engine off!- There are two basic types of cutoff discs:- For metal (hot cutting)- For masonry (cold cutting)NOTE:When using diamond cutoff discs, always make sure to observe the"direction of rotation" markings. Diamond discs should only beused 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 disk! This will break thedisk! (10)!Caution!Never change direction (turning radius less than 5 meters /16 feet), exert lateral (sideways) pressure, or tip the Power Cutduring cutting (11)!- Use a cutting disc only for cutting the materials it is intended for.The proper type of disc must be used, for either metals ormasonry.- The arbour hole (bore) of the cutting disc must fit the shaftexactly. If the arbour hole is larger than the shaft diameter, aspacer ring must be used.- Use only cutting wheels approved by the DSA (German Abra-sive Disc Committee) or equivalent organisation for freehandcutting at up to 4370 RPM (= 80 m/sec. at circumference) for14"/350 mm discs, or up to 5100 RPM (= 80 m/sec. at circum-ference) for 12"/300 mm discs.- The disc must be free of defects (12). Do not use defectivecutting discs.Always tighten the cutting disc mounting bolt to a torque of 30Nm. Otherwise, the cutting disc can twist.- Before starting the cutting disc, make sure you have a steadyfooting.- Put the Power Cut into operation only as described in thisinstruction manual (13). Always place your left foot in the rearhandle and grasp the other handle firmly (with thumb andfingers). Other starting methods are not allowed.- When starting the Power Cut it must be well supported andsecurely held. The cutting disc must not be touching anything.- If the cutting disc is new, test it by running it at least 60 secondsat top speed. When doing this, make sure that no persons orbody parts are in the extended swing range of the disc, in caseit is defective and flies apart.- When working with the Power Cut always hold it with bothhands. Take the back handle with the right hand and the tubularhandle with the left hand. Hold the handles tightly with yourthumbs facing your fingers.- CAUTION: When you release the throttle lever the disc willkeep spinning for a short period of time (free-wheelingeffect).- Continuously ensure that you have a safe footing.- Hold the Power Cut such that you will not breathe in the exhaustgas. Do not work in closed rooms or in deep holes or ditches(danger of poisoning by fumes).- Switch off the Power Cut immediately if you observe anychanges in its operating behavior.- Switch off the engine before inspecting the V-belt tensionor tightening it, replacing the cutting wheel, repositioningthe cutter attachment (side or middle position) or eliminatingfaults (14).- Turn off the engine immediately and check the disc if you hearor feel any change in cutting behaviour.- Turn off the Power Cut when taking a break or stopping work(14). Place the unit in such a way that the disc is not touchinganything and cannot endanger anyone.- Do not put the overheated Power Cut in dry grass or on anyinflammable objects. The muffler is very hot (danger of fire).- IMPORTANT: After wet cutting, first turn off the water feed andthen let the disc run at least 30 seconds, to fling off the remainingwater and prevent corrosion.1011131214 Maintenance Refuelling Changing cutoff discs Repositioning thecutting attachment Stopping work Transport Putting out of functionSTOPmin. 5 m(16 feet)
