Definition ofTampingRammer
TampingRammerisacompactingmachine,capableofquicklyworkingbyapplyingconsecutive
impactstothe surfaceofsoil-inordertolevelthe uneven soil surface,tocompactthe soil uniformly
sothatthe voidamongsoilparticlesareminimized and toincreaseitsdrydensitywithmoistureinthe
soil removed.
Construction ofTamping Rammer
Air-cooled engine hasbee installed asitssourceofpower.
Transmission ofthe poweristakenplacebyincreasingengine speedtoengageacentrifugalclutch,
and thespeed issubstantiallyreduced bymeansofgearsand rotationalmotion isconverted into
reciprocal(vertical)motion.

Operation
Starting up forPetrol engine
1.Open the fuelshut-offvalvebymovingthe fuelcock leveltothe open position.
2.Set theengine ON/OFF switchtothe “ON”position.
3.Gripthe recoil starterhandleandpull ituntil you feelslightresistance.Thenpull sharplyand
quickly. Returnthe recoil starterhandletothe startercasebeforereleasing.
4.Gripthe recoil starterhandleandpull italittletofeelaslightresistance.Thenpull itpowerfully

the coil orclean sufficientlytoitsinternals.Withthe ignition plugremoved,pullthe recoil starter
handle2-3timestodischargeexcessiveblended gas.
Starting up formachine
1.Turningthechokeleveltoopenthechoke.Running the engine for5minutesatlowspeed to
warmthe engine.
2.Movethe throttlelevelquicklytothe “FULLOPEN”position.DONOTmovethe throttlelevel

Caution: Makesurethatthe throttleleverismoved tothe FULLOPENposition.Operatingthe
rammerat less than full speedscan result indamage tothe clutchspringsorfoot.
3.Afterstartingtotampingaction,adjuststhe jumpingmotion tosuitparticularsoil condition by
lightlycontrollingthe throttlelever.When the enginespeed fallsbetween the setvaluesshown
