28 enThe connected load of the power toolmay not exceed the maximum con-nected load P A of the vacuumcleaner’s socket outlet.Please also observe the operatinginstructions and safety warnings ofthe power tool being connected to thesocket outlet of the vacuum cleaner.Recommendation: Always operate thevacuum cleaner via a residual currentdevice (RCD) with a rated residualcurrent of 30 mA or less.The vacuum cleaner may only bestored indoors.Operating Instructions.Operation, see page 10.Filter replacement and filter cleaning,see page 11–13/ 30 section “FaultFinding.”Never vacuum with-out the flat-fold filter,as otherwise the motor will be dam-aged and a health hazard will occurthrough increased exposure of finedust. When vacuuming fine dust, afleece filter bag must be used addi-tionally.An adequate ventilation rate L mustbe provided for when the outgoing airis circulated. The circulated airflowmust not exceed 50 % (max.) of thefresh air volume (room volume x ven-tilation rate Lw ). The following applieswithout special ventilation measures:Lw = 1 h -1.When inserting the fleece filter bag,pay attention that the closing coverand the fleece bag face completelyagainst the interior side of the con-tainer.After removing the fleece filter bag,seal it with the closing cover in orderto avoid debris.For vacuuming dusts of dust cate-gory L, only dry flat-fold filters,which have not been moist or wet,are permitted to be used.Before switching from wet to dryvacuuming, allow the flat-fold fil-ter to dry or replace through a dryone. Otherwise, the flat-fold filter willbecome unusable.Keep the flat-fold filter dry and cleanit regularly.Mount accessories applying only slightpressure. For disassembling, turn theparts somewhat against each otherand pull apart.Switch the vacuum cleaner off beforeconnecting a power tool to the vac-uum cleaner’s socket outlet. Makesure that the power tool is switchedoff when inserting its plug into thevacuum cleaner’s socket outlet.After switching off a power tool con-nected to the vacuum cleaner’s socketoutlet, the vacuum cleaner will run onfor approx. 15 seconds and thenautomatically switch off.When wet vacuuming electrically con-ductive liquids, the vacuum cleaner isautomatically switched off (automaticshut-off) when reaching the maximumfilling height of the container. Pull themains plug from the socket outlet andempty the container.When wet vacuuming electricallynon-conductive liquids (e. g., oils,drilling emulsions), the vacuumcleaner is not automatically switchedoff when reaching the maximum fillingheight of the container. Empty thecontainer in time.CAUTIONOBJ_BUCH-0000000148-003.book Page 28 Tuesday, May 5, 2015 1:22 PM
