(industrial type vacuum cleaners)

D When removing and installing components do not use materials such as cloths, cardbo-
ard or wood since these could shed particles and fine fibres

ting) these chippings must be carefully removed before finally loosening the screw con-
nection

to be closed immediately with suitable caps (see special tools, page 172)

D Never use used cleaning or testing liquids for these components
D New parts must not be removed from their original packing material until directly before
use
D Work on removed components may be carried out only at a workplace specially equip-
ped for it
D If removed parts are shipped always use the original packing material of the new part
