Ahumming(only)soundisanindicationthatthemotorhas

electricalpowerbutismechanicallyblocked.Thismaybe

causedbythefollowingconditions:

1) Checkthattheshavingsreceptaclehasbeenemptied.

severelyover‐filledreceptaclecancausepencil

shavingstobackupintotherotatingpartsandjam

them.

2) Checkthatthecutters,cuttercarrier,andtheinternal

gear(locatedatthebaseofhelicalcutters)arefreeof

excesspencilshavings.Iftheshavingsreceptaclehas

previouslybeenoverfilled,

theremayberesidual

Tocleartheshavings:

a) Unplugthesharpener.Removetheshavings

b) Whileholdingthesharpeneroverawastebasket,

gentlytapwithonthesideswiththepalmofa

Inspectthecuttersandinternalgearforany

remainingpencilshavings(thisusuallyrequires

turningthesharpeneroverand/orholdingitatan

angle).Anyremainingshavingsintheinternalgear

canberemovedwithasmalltoolsuchasapaper

3) Checkforandremoveanyforeign

Sharpener“hums”whenapencilininserted

Off‐centersharpening/Sharpensoneside

only/Sharpenstoawoodpoint

Thisisacommoncustomercomplaint,butrarelyisitdueto

adefectinthesharpener.Whensharpenersareoperating

normally,thecutter(s)andcarrierrotateallthewayaround

thepencilmanytimessothatthey“see”allsides

ofthe

pencilequally.Whenthesharpeningisuneven/not

centered,itisusuallyduetosomeexternalfactors.



Thefollowingtipsarehelpful toobtainthebestresults:

1) Onmulti‐size‐pencilsharpeners,makesurethatyou

haveselectedtheholethatprovidesthebestfitfor

thepencil.

Any“slop”inthepencilfitwilltranslate

intosomeoff‐centeredness.

2) Holdthepencilwitha“neutral”grip,notpressingitin

anydirection(up,down,le ft,orright).Anysideforce

onthepencilwilloffsetthecutting.

3) Keepthepencilincontactwiththecuttersbut

don’t

forceit.Letthecuttersdothework.

4) Yes,sometimesthegraphitecoreofthepencilisoffset

fromthecenterofthewoodcasing.Itseemstooccur

randomly(evenwithinthelengthofapencil)with

somebrandshavingtheissuemorethanothers.

5) If

youhaveastubbornpencil,youcanignorerule#2

andapplyaslightsideforceinthedirectionofthe

excess‐graphitesidetotakeoffmoreofthewood.

Severeoff‐centersharpening(tothepointwherethe

pencilisnotusableforwriting)cansometimesbecaused

aworninternalgear.Thisring‐shapedgearislocatedat

thebaseofthecutter(s).Internalgearwearmustbe

significant(visuallyobvious)tobethecauseofoff‐center

sharpening.

Cuttercarrierisrotatingbutthepencilis

notsharpening(doesn’tfeellikethecutter

isengagingthepencil)

Thisisusuallycausedbyaf oreignobject(e.g.,aneraseror

brokenpencillead)insidethepencilbore.Examinethe

pencilboreasinitem3ofthe“hums”sectionabove.

Ifthe

objectisloose,itmayfalloutthefrontofthesharpener.If

notloose,itmaybepossibletopushitloosefrominside

theshavingsreceptaclecompartmentwithapaperclip.Ifit

isnotpossibletodislodgetheobject,partialorfull

disassemblyofthe

forthis,unplugthesharpener,removethereceptacle,and

turnthesharperover.Lookforandremoveanyforeign
