C.Toavoidinjuryor
damagetopersonnelanditemsintheworkarea,observethefollowing:
●Donottouchthetiporthemetalpartsnearthetip.
●Donotallowthetiptocomecloseto,ortouchflammablematerials.
●Informothersintheareathattheunitishotandshouldnotbetouched.
●Turnthepoweroffwhennotinuseorleftunattended.
●Turnthepoweroffwhenchangingpartsorstoringthestation.
Topreventaccidentsordamagetothestation,besuretoobservethefollowing:
●Donotusethestationforapplicationsotherthansoldering.
●Donotallowthestationtobecomewetoruseitwhenhandsarewet.
●Do not strike the iron against hard objects to remove excesssolder as this will
damagetheiron.
●Removepowerandironcordsbyholdingtheplug—notthewires.

MAINTENANCE
A. TipMaintenance
1.TipTemperature
High temperature shortens tip life andmay cause thermal shock to components.
Alwaysusethelowestpossibletemperaturewhensoldering.Theexcellentthermal
recovery characteristics of the 2901 station ensures effective soldering at low
temperature.
2.Cleaning
Always clean the soldering tip before use to remove any residual solder or flux
adheringtoit. Use acleanandmoistcleaningsponge. Contaminantsonthetip
havemanydetrimentaleffectsincludingreducedheatconductivitywhichcontribute
topoorsolderingperformance.
3.Afteruse
Always cleanthe tip and coat it withfreshsolder after use.  This guards against
oxidation.
4.Whentheunitisnotbeingused
Neverallowtheunittostayidleathightemperatureforextendedperiods.Thiswill
allow the tipto become oxidized.  Turn the power switch OFF ifit is tobe out of
serviceforseveralhours.Itisadvisabletopullthepowerplugaswell.
5.Inspectingandcleaningthetip
Thisprocedure,iffolloweddailywillmateriallyaddtotiplife.
1.Setthetemperatureto250
o
C.
2.Whenthetemperaturestabilizes,cleanthetipandcheckitscondition.Ifthetip
isbadlywornordeformed,replaceit.
3.Ifthesolderplatedpartofthetipiscoveredwithblackoxide,applyfreshsolder
containingfluxandcleanthetipagain.Repeatuntilalltheoxideisremoved
thencoatthetipwithfreshsolder.
Neverfilethetiptoremoveoxide.
4.TurnthepowerOFFandremovethetipusingtheheatresistantpad.Setthe
tipasidetocool.
5.Remainingoxidessuchastheyellowdiscolorationonthetipshaftcanbe
removedwithisopropylalcohol.
