Iftheunitdoesnotpressurizewhenyouturniton:
• Istherepowertotheunit?Doesthelightonthepowerswitchilluminate?
Ifnot,checkthepowercordconnectionsatthebackoftheunitandatthepowersource.Checkthefuse.
• Istheairlineconnected?Aretheupstreamvalvesopen?
Checktheinletairsupply.
• Doyouhearairescapingfromtheunitwhenitisturnedon?
Checkthattheinletair,venthose,andabrasivehoseexitingthePowderGate®valveareconnectedproperly.
Seetheset‐upguideonpages4and5.Makesurethetankcoverissecurelyfastened.
Ifyouaregettingairthroughthenozzle,butnoabrasive;orifthecuttingactiondecreases:
• Isthepowdertankempty?Refill.
• Istheabrasiveinthetankdampandstickingtothewalls?
Replacewithfreshpowder.Checkthatyourairdryerisworkingproperly.
• Isthetankorificeplugged?
Emptypowder,removeorifice,andinspect.Checktoseeifyoursupplierofabrasivepowderisprovidinghigh
qualitymaterial.FordetailsseetheSupportsectiononourwebsite.

TubeChartforaleanermixturetohandleyournozzlesize.
PreventMoistureandOilContamination
Contaminationoftheabrasivepowderfrommoistureand/oroilisoneofthemostcommonproblems
associatedwithmicro‐abrasiveblasting.Moisturewillcausethepowderto“clumpup,”preventingitfrom
flowingfreelyfromthetank.
Moisturewillcausethepowderto"clumpup"preventingitfromflowingfreelyfromthetank.
Oilintheairsupplywillnotonlyaffectabrasiveflow,itcanalsocausemajorcomponentfailureswithinyour
blaster,resultingincostlyrepairs.
Toavoidmoistureandoilcontamination,runyourairsupplythroughapositiveairdryerequippedwithan
appropriateoilfilter.
