BEFORE START OF OPERATION
1.InspectionandRellofEngineOil
(1)Performthefollowingprocedure,withtheenginecooleddown.
•Inspection:Pleaseinspectwhetheritmakesthemachinehorizontal,removestheoilcap,thereisaoiltoinsidetherangeoftheupperlimitlower
limitmarkofgauge.Whenitisinsufcient,(especially,whenithasnotreachedtothelowerlimitlevel),pleaserellnewoil.
•Rell: Verticality(underthesuctionportcover)pleasedothemachine,removetheoilcap.Whenoilissuppliedfromtheoilpipeportand
oillevelcomestotheshelfinsidetheoilpipe,pleasestopoilsupply.
(2)Forreference,theoilrelltimeisabout10h(rellfrequency:10times).
(3)Iftheoilchangesincolorormixeswithdirt,replaceitwithnewone.(Fortheintervalandmethodofreplacement,refertoP.14)
Recommendedoil: SAE10W30oilofAPIClassication,ClassSForhigher(4strokeengineforautomobile)

NOTE
Iftheengineisnotkeptupright,oilmaygointoaroundtheengine,andmayberelledexcessively.
Iftheoilislledabovethelimit,theoilmaybecontaminatedormaycatchrewithwhite.

Point1inReplacementofOil“OilGauge”
Removedustordirtneartheoilrellport,anddetachtheoilgauge.
Keepthedetachedoilgaugefreeofsandordust.Otherwise,anysandordustadheringtotheoilgaugemaycauseirregularoilcirculationor
wearontheengineparts,whichwillresultintroubles.
Asanexampletokeeptheoilgaugeclean,itisrecommendedtoinserttheoilgaugeonitsknobsideintotheenginecover.

Useofdeterioratedoilwillcauseirregularstartup.
●
●
Whenrefuelingthefuel,besuretostoptheengineandconrmthattheenginecoolsdown.
REFUELINGMETHOD
Loosenthetankcapalittlesothattherewillbenodifferenceinatmosphericpressure.
Detachthetankcap,andrefuel,dischargingairbytiltingthefueltanksothattherefuelportwillbeorientedupward.(Neverrellfuelfulltotheoil
rellport.)
Afterrefueling,securelytightenthetankcap.
Ifthereisanyawordamageonthetankcap,replaceit.

NOTE
Theenginemaybedamagedifthechokeleverismovedfurtherbeyondthe“CLOSE”position.
Iftheenginestopswithanexplosionsoundoriftheenginestarted,butstoppedbeforeoperationofthechokelever,returnthislevertothe
“OPEN”positionandpullthestarterhandleseveraltimestostarttheengineagain.
Iftheoperatorkeepspullingthestarterhandleseveraltimeswiththechokeleverleftinthe“CLOSE”position,theenginemaybedifculttostart
becauseofoversuctionofthefuel.
Incaseofoversuctionofthefuel,removethesparkplugandpullthehandleseveraltimesrapidlytodischargeanyexcessfuel.Drythespark

OPERATIONMETHOD
1.Bloweroperation
Holdthemachinermlyduringoperation.
Direct the nozzle end toward the object to be dusted and pull the
triggerlever.
Thetriggerlevercanbexedinanarbitrarypositionwiththecruise
controllever.
Maintainthetriggerleveratapositionwheretheenginespeedap-
propriate for the operation is obtained and set the cruise control lever
tothe“ON”position.
Toadjusttheenginespeed,setthecruisecontrollevertothe“OFF”
positiononce,adjusttheenginespeedwiththetriggerleveragain,
thensetandxthecruisecontrollevertothe“ON”position.
Operationofthetriggerleverwiththecruisecontrolleverinthe“ON”
positionmaycausefailure.
The lower portion of the fuel tank acts as an assist handle, which
enablesoperationwithbothhands.Inthiscase,besuretoholdthe
assisthandlewitharighthand.
