5) Alwaysdisconnecttheairsupplyfromthesanderbefore
tting,adjustingorremovingtheabrasiveorbacking
pad.
6) Alwaysadoptarmfootingand/orpositionandbeaware

10) Donotexceedmaximumrecommendedairpressure.
Usesafetyequipmentasrecommended.
11)Thetoolisnotelectricallyinsulated.Donotusewhere
thereisapossibilityofcomingintocontactwithlive
electricity,gaspipes,waterpipes,etc.Checktheworkingareabeforeoperation.
12)Takecaretoavoidentanglementofthemovingpartsofthetoolwithclothing,ties,hair,
cleaningrags,etc.Ifentangled,itwillcausethebodytobepulledtowardstheworkand
movingpartsofthemachineandcanbeverydangerous.
13) Keep hands clear of the spinning pad during use.
14) Ifthetoolappearstomalfunction,removefromuseimmediatelyandarrangeforservicing
