The internal parts are protectedaga inst dust by total enclosure. The h an dle moun ted switch is a ls oenclosed. Highe st po ss ible w orking safety is a tt ai ned by th e rubbersheating.The grinder MSfo 880-1 is an electric tool of class I wi th safe tyconductor according to VD E reg ul a tion s 0740. For saf ety reasons themark ed safety conductor of the supp ly ca ble, connected to the metalcasing of the machin e, mu st be connected to the prot ecting contact ofthe plu g.

OperationFirst check that details on the rat ing plate agr ee with those of the hi ghfrequen cy supply.In o rd er to a void con stant overload, e.g. w hen cutting off , we re -commend the installation of a saf ety switch correspon din g to th erated current of the motor (see also sep a rated in struction B 22).Switch mu st be in th e "Off " position when connectin g.Check th at the tool rot ates in direction marked by arro w on them achin e, otherwi se the chucked tool may become loo se . To checkrotation switch on tool bri efly. If it does n ot follow a rro w, re verseby ch anging over t wo leads in the plug.Ty pe MSfo 880-1d, MSfo 880- ldK a nd MSfo 880-1c, MSfo 880- 1cKmust not be used w ithout wh ee l guards.Do not exceed the dim ensions of gr inding w heels stip ulated. Whenworking wi th crank wheel hold tool in such a pos itio n th at th eg rindin g wh ee l works under an ang le of 15- 30° . For cutti ng off usecutt in g-off w h ee l with the prescribed flanges, f or cut t in g off stoneuse our wheel gua rd w ith adjustable support.F urther mor e, the ha ndl e should be screwed into t he right ha nd bo reof the housing (seen from above) for cutting off, in order to pr eve ntthe grinding dust from being thro wn into the air inlet of the machin e.
