Desoldering
AfterturningthepowerswitchtoON,
wait3minutesbeforebeginningdesol-
deringoperations.
1. Set the temperature.
CAUTION
Alwayssetthetemperaturetoaslow
aspossiblefortheworkbeingdone.
• Tomorepreciselysetthetempera-
ture,measurethetemperatureat

Wipeawayanyoxideoroldsolder
fromthenozzleusingtheholein
thecenterofthesponge.
2. Clean the tip of the nozzle.
• Keepthesolder-platedsectionof
thenozzleashinywhitebycoating
itwithasmallamountofsolder.
Ifthetipofthenozzleiscoatedwith
oxide,thenozzle’sheatconductivity
willbelowered.
Coatingthetipwithasmallamount
offreshsolderensuremaximumheat
conductivity.
3. Melt the solder.
• Applythenozzletothesoldered
partandmeltthesolder.
CAUTION
Neverallowthenozzletotouchthe
boarditself.
• Conrmthatthesolderismelted.
CAUTION
Toconrmthatallsolderismelted,
observetheinsideoftheholeandthe
backsideoftheP.W.B.Ifthisisdifcult
todo,tryslowlymovingtheleadwith
thenozzle–Iftheleadmoves,the
solderismelted.
CAUTION
Nevermovetheleadbyforce.Ifit
doesn’tmoveeasily,thesolderisn’tyet
fullymelted.
4. Absorb the solder.
• Afterconrmingthatthesolderis
completelymelted,absorbthesol-
derbysqueezingthetriggeronthe
gun.
CAUTION
Neverleaveanysolderremaining
insidetheholeintheP.W.B.
• Afterfullyabsorbingallthesolder,
coolthesolderingjunctioninorder
topreventitfrombecomingresol-
dered.

5. Operation
Heatedsolderanduxcancauseoxidestoformandadheretothenozzleandthe
insideoftheheatingelement.Theseoxidesnotonlylowertheheatconductivity,but
canalsoclogthenozzleandheatingelement,resultinginadropinsuctionefciency.
Shouldtherebeanoticeabledropinsuctionefciencyduringoperation,replacethe
lterandcleanthenozzleandheatingelementwiththeprovidedcleaningpin.
Cleaning during Operation
1. Observing the indicator
Whilelookingattheindicatorand
withtheholeofthenozzleopen,
pullthetriggerandlookatthein-
dicator.Ifitisred,cleanthenozzle
andheatingelement,emptythe
lterpipe,andreplacethelters.If
theindicatorisblue,cleaningisnot
necessaryandoperationscanbe
resumed.
CAUTION
Theindicatorwillnotoperateaccuratelyif
theholeofthenozzleisclosedorifthesol-
derintheholeoftheP.W.B.isnotmelted.
CAUTION
TheindicatorontheHAKKO475reads
inadifferentway.
Forinstructiononthereadingthe
HAKKO475indicator,pleasereferto
theHAKKO475instructionmanual.
2. Replacing the lter
Replacethelterasshown1to3.
Duringoperation,thelterpipeis
veryhot.Waituntilthelterpipeis
coolbeforereplacingthelter.
Werecommendkeepingasecond
lterpipecontainingnewltershan-
dy,andreplacingtheinstalledlter
pipewiththisbackuplterpipe.

withheprovidedbackuplterpipe. 2 Pull
1 Down
Normal
Blueorslight

can be seen.
Abnormal
Morethanhalf
oftheindicator
isred.
Solution
Iftheindicatorismorethan
halfred,replacethelter
andcleanthenozzleand
theinsideoftheheating
element.
(refertop.12Maintenance
oftheDesolderingGun)
CAUTION :Ifthereisanoticeabledropinsuction
efciency,cleanthenozzleandheatingele-
mentwiththecleaningpin.
Problems during Desoldering

A. The solder in the junction is not sufciently melted.
lTemperature is not high enough
Thefollowingpartsrequireagreaterheatcapacitytodesolder.

Properlymaintained,theHAKKO474desolderinggunshouldprovideyearsofgoodservice.
Efcientdesolderingdependsuponthetemperature,andthequalityandquantityofthesolderandux.Per-
formthefollowingserviceproceduresasdictatedbytheconditionsofthegun’susage.
WARNING : Sincethedesolderingguncanreachaveryhightemperature,pleaseworkcarefully.
Exceptwhencleaningthenozzleandheatingelement,alwaysturnthepowerswitchoffanddiscon-
nectthepowerplugbeforeperforminganymaintenanceprocedure.
Servicing the Desoldering Gun
CAUTION
Thedesolderinggunwillbeextremelyhot.
Duringmaintenance,pleasewearglovesand
workcarefully.
1. Inspect and clean the nozzle.
• Pluginthepowercord,turnthe
powerswitchOnandletthenozzle
heatup.
• Cleanouttheholeofthenozzle
withthenozzlecleaningpin.
CAUTION
Thecleaningpinwillnotpassthroughthe
nozzleuntilthesolderinsidethenozzleis
completelymelted.
• Ifthecleaningpindoesnotpass
throughtheholeinthenozzle,
cleanwiththecleaningdrill.
• Checktheconditionofthesolder
platingonthetipofthenozzle.
• Ifitisslightlyworn,recoatthetipwith
freshsoldertopreventoxidation.
• Checktheconditionofthesurface
andinsideholeofthenozzle.
• Ifeitheriswornoreroded,orthe
insidediameterseemsunusually
wide,replacethenozzle.
CAUTION
Theinsideholeandthesurfaceofthe
nozzleisplatedwithaspecialalloy.
Shouldthisalloybecomeerodedbyhigh-
temperaturesolder,thenozzlewillnotbe
abletomaintainthepropertemperature.
2. Disassemble the heating
element.
CAUTION
Theheatingelementisveryhotduring
operation.
3. Clean out the hole in the
heating element with the
provided cleaning pin.
CAUTION
Besurethesolderintheholeintheheat-
ingelementiscompletelyheated,before

測量條件
．絕緣電阻
使用一個 DC500V 的絕緣電阻測量計 , 在吸嘴和發熱元件引線之間測量絕緣電阻。
注意 : 不可在吸嘴和電源插座之間測量絕緣電阻 , 因為第二側是與第一側和變壓器絕緣。
．漏電壓
使用交流電毫伏測量計 , 在吸嘴和接地插座之間 , 於 480℃的情況下 , 進行測量漏電壓。
注意 : 控制臺必須接地 , 才可進行測量漏電壓。
．規格及外觀可能改良變更 , 恕不先行通知。

3. 安全及使用上的注意事項
18
本使用說明書如下所述將注意事項區分為「警告」「注意」來表示。請理解其含意後再閱讀本文。
中 文
注意
本產品施有防靜電措施，對塑膠導電性，並對焊鐵部與
機身部作接地，請特別留意下列注意事項 :
1.手柄等之塑膠，並非絕緣物，而是有導電性塑膠，修
理時請十分注意之。進行部件更換或修理時，有電部
分不可露出，及切勿損傷絕緣材料。
2.請務必接地使用之。

警 告
警 告：濫用可能導致使用者死亡或重傷。
注 意：濫用可能導致使用者受傷或對涉及物體造成實質破壞。
注 意
使用之前必須除去控制臺底下的泵拴緊螺絲 (M4×25 紅色記號 ),
否則可能導致嚴重後果。
當電源接通時 , 吸嘴溫度介於 380 至 480℃。
鑒于濫用可能導致灼傷或火患 , 請嚴格遵守以下事項。
●切勿觸及吸嘴周圍的金屬部分 , 塑料部分和彈簧式吸錫槍支架。
●切勿在易燃物體附近使用吸錫槍。
●通知工場其他人士 , 吸錫槍極為炙熱 , 可能引發危險事故。
●休息時或完工後 , 應關掉電源 , 並待吸錫槍冷卻至室溫。
●更換部件或裝配吸錫槍時 , 應關掉電源 , 並待吸錫槍冷卻至室溫。
為避免損壞吸錫槍及保持作業環境之安全 , 應遵守下列事項。
●切勿使用吸錫槍進行吸錫以外的工作。
●切勿以吸錫槍敲擊工作臺以清除焊錫殘餘 , 此舉可能嚴重震損吸錫槍。
●切勿擅自改動吸錫槍。
●更換部件時 , 應採用 HAKKO 原件。
●切勿弄濕吸錫槍 , 手濕時也不可使用吸錫槍。
●陶瓷過濾紙 ( 小 ) 只可裝在控制臺過濾器內 , 而陶瓷過濾紙 ( 大 ) 只可裝在吸錫
槍過濾管內。
●應定期保養吸錫槍和控制臺。
●使用吸錫槍時 , 不可做出任何可能傷害身體或損壞物件的妄動。
