(11)Lightthealcoholinthepre-heatingtray.Justbeforethealcoholisconsumed,opentheneedle
valveslowlytoabout15degreesforburnerignition.*Ifnotpreheatedsufficiently,thealcoholwill
notbevaporized.Insuchcases,closetheneedlevalveandrepeattheprocess(9)above.
*Themaximumopeningoftheneedlevalveisabout60degrees
fromfullclose.Adjusttothebestpositionafter10minutesʼ
operation.
*Usuallyitʼ snotnecessarytoopenneedlesofbothnozzles.When
youwantgreatersteamfortheengine,openingbothneedlesis
required.
Steamup*Usingthepressuregauge(option)ishighlyrecommended.
(12)Aftertheburnerisignited,ittakesabout8-12minutestoraisepressuresufficiently.Whenthe
pressuregaugeshows1.0~1.5kgf/cm2,opentheregulatorquicklytofullopenpositionandreturn
tofullclosepositiontogetridofremainingairinsidetheboiler.Thenpressuredropsimmediately
andrisesgraduallyagain.
(13)Whenthepressuregaugeshows1.0~2.0kgf/cm2,Steamupiscompletedandnowyoucan
operateregulatorstoruntheengineorusethewhistle.
CAUTION
◆1.Alwayskeepfuelcan,containers,andburnablematerialawayfromtheburner.Andkeepawet
towelnearbyforanemergency.
◆2.Excessivetighteningmaygreatlyshortenthelifeofpackings(O-ring,gasket,orglandpacking)
andevenstriporbreakthethreadedpartoftheneedlevalve,safetyvalves,andoverflowplug.
◆3.Alwaysusefixedwaterandfuellevelsfortheboilerandburners.
◆4.Donotfilluptheboilerwithhotwater.
◆5.Ifyourestarttheengineafterstoppingtheburnerforciblybyclosingneedlevalve,theremaybe
fuelremainingintheburner.Insuchcases,theburnercanbere-litimmediatelywhilethetankis
stillhot.ButthenDONOTaddanyfuel.
Orafteritgetscold,draintheremainingfuelfromtheburner(removethesafetyvalve[C]and
turntheburnerupsidedown),andfollowtheprocessoutlinedin(3)to(13)abovetorestart.
◆6.Incaseofengineracing,adjusttherpmusingtheneedlevalveandtheregulator.Operatingthe
engineathighrpmcancauseexcessivewearorotherdamage.
◆7.Aslongasyoufeedrecommendedquantitiesofwaterandfuel,theflamewillextinguishinabout
25minutes.Thequantitiesaremeasuredtoensurethattherewillbewaterleftintheboilerwhen
theflameisextinguished.Ifexcessivefuelisused,theboilerwillbecomeoverheatedafterthe
waterhasbeendepletedandtheflamecontinues.Thisdrysuperheatingcanbreaksomewelded

◇4.
Becausecarbontendstocollectonthenozzles,cleanthenozzlesaftereverytenoperationsusing
theattachedwire.
*Donotuseawireotherthantheattachedonetocleanthenozzlesasanythickwiremayreduce

・ニードルバルブをあけすぎると、生ガスの発生と、燃焼の妨げになります。あけすぎない
ようご注意下さい。
・オイルは、専用のスモークオイルをご使用下さい。
・ニードルバルブはデリケートなので、過度な開閉は避けて下さい。
・２回目からは、発煙タンク内のドレンを抜いてからオイルを入れて下さい。
・Toomuchopeningoftheneedlevalvecausesraw-gasanddiscouragecombustion.So
takecarenottoopenthenozzletoomuch.
・Usethededicatedoilforthesmoke.
・Theneedlevalveisverydelicatesoavoidopeningtoowideorclosingtootight.
・Fromthe2ndoperation,pourtheoilintothetankafterremovingwasteoilfromthetank.
