Pre-Operation Check
1.Engine oil level
Removethe oil fillercapand check the oil level: it shouldreachthetopofthe oil filterneck.
Ifthe levelislow, fill tothe topofthe oil fillerneck withthe recommended oil.
Add theengine oil slowlytoavoidoverflowing, asthe engine oil tankcapacityissmall.
Every10 hours, check the engine oil leveland replenishoil up tothe topofthe oilfillerneck ifthe engine
isoperated formorethan 10hourscontinuously.
UseHonda 4-stroke,oranequivalenthighdetergent, premiumqualitymotoroil certified tomeetor
exceed U.S.automobilemanufacturer srequirementsforserviceclassification SG,SF.Motoroils
classified SG,SFwill showthisdesignationonthecontainer. SAE10W-30 isrecommended forgeneral,
all temperatureuse.
CAUTION:
Usingnondetergent oil or2-strokeengine oil couldshorten the enginesservicelife.
Therecommended operatingrangeofthisengine is-5℃to40℃(23℉to104℉)
2.Aircleaner
CAUTION:
Neverrun the engine without the aircleaner. Rapidengine wearwill result.
Check cleanerfordirt orobstruction ofelement.
3.Fuel
Useautomotivegasoline (Unleadedorlowleadedispreferred tominimizecombustion chamber
deposits).
Neverusean oil/gasoline mixtureordirtygasoline.Avoidgettingdirt, dust orwaterinthe fueltank.
4.Retighteningboltsand nuts
Check forlooseboltsand nuts.Tighten the boltsandnutsproperlyandsecurely,ifnecessary.
Staringthe Engine
1.Turnthe engine switchtothe ONposition (on the equipment side).
2.Movethe chokelevertotheCLOSEDposition.
Note: Donot usethe chokeifthe engine iswarmorthe airtemperatureishigh.
3.Press the primingpumpseveraltimesuntil afuelflowinthe fuelreturntubeisvisuallynoticed.
4.Pull the startergriplightlyuntil resistanceisfelt, thenpull briskly.

6.Keeptheengine atleast1mtr.awayfrombuildings,obstructionsand otherburnableobjects.To
avoidgettingan electricshock,donottouchthe sparkplugorsparkpluglead duringengine
running.Toavoidaseriousburn,do nottouchahotenginemuffler.Beforeyou serviceorremove
partsstopengine andallowthe engine tocool.
7.Alwaysremovethe sparkpluglead fromsprakplugwhen servicingthe engine toprevent accidental
starting.
Read theinstruction manualofthe petrolengine.
HowToAdjustTheBladeAngle
Pleaseobservethefollowinginstructions:
lMakesuretorefill the fueltankintime.Donotletthe engine run soall the fuelisused.Thismight
causestartingproblems.
lPreventtheMMDof sinkingintotheconcrete.Afterthe engine hasbeen switched on, immediately
movethe MMDbackwards.
lWhen usingalowslumpconcrete, movethe MMDslowlyacross the surfaceofthe concrete.When
usingahighslumpconcrete,movethe MMDfasteracross the surfaceofthe concrete.
UsageRecommendations
Thescreedsareusedtothevibration and thefinishingof thefloors.Thisworkcan bemade directlyon
the surfacewithoutguides. Thanks toitslightweightand toitsmechanismproducingapowerfulvibration,
the screed isidealtosmoothrapidlyand easilythe floors(from6to18 cmthickness)dependingon the
concretetype.
Inordertoget agood finishingofthe concretesurface, werecommend tofollowtheseinstructions:
Turnin
gthehandletotheright,
the blade inclinesforward, pushing
and spreadingthe concrete.
Turningthehandletotheleft,
tomakethe blade incline backward,
pullingand spreadingthe concrete.

1.-Beforepouringthe concretemass on thestructure,itisnecessarytolevelproperlytheconcrete
mass.Togetarightcompaction ofthe concrete,youshouldusethevibratingpokersadditionally.
It'simportanttotakereferencesorlevelsoutofthe mass toseethelevelobjectiveclearly.The
marks ofthe feetand thetooldisappearafterthe lastpass ofthe screed.The vibration wave
produced, reachesadepthof18 cmdependingon the typeofconcretemass.
2.-When the mass isprepared, the screed islaidoverthe concretemass withthe motorrunningat the
topspeed andyoumustsupportthe handlelightlyinordertoavoidthe screedjumpsoverthe
surfaceand doesnot create"waves"and "marks"withedges. Pull and pushconstantlythe screed.
It isimportanttogetasmoothsurface.The screedmustbeincontactwiththe concrete.The
screed mustnot showanyresistancetopulling,itmustslipoverthe concrete. Thespeed topush
and pull the screeddependsonthedepthand the consistencyofthe mass.
3.-Tojudgethe qualityofthe vibration,the marks ofthe feetand the beammustdisappear.Incaseof
the concreteisnotreallysmooth, repeat the previousinstruction.
4.-Then,amixturecalled "milk"appearson thesurface(thisisamixtureof3-4mmthickness
composed ofwater, concrete, andsmall sand particles).
5.-Watermust evaporatequicklyand thesurfacewill becomedull.The fine layercalled "milk"isacting

layersandthesurfacemoistens.
6.-Severalhourslater,theconcreteisreadyforadditionalfinishingoperations.Youcanuseatrowel
