LIFT CYLINDER
Thisisadirect-actingvalve.Pushingthevalvehandleforwardwillcausetheliftcylindertoliftthetongvertically.Pullingthe
valvehandleintheoppositedirectionwillcausetheliftcylindertolowerthetong.
3. SHIFTING GEARS
Theshiftingshafthasthree“detent”positionsidentifyingthelowspeed/hightorqueposition,the“neutral”orfree-spinningposi-
tion,andthehighspeed/lowtorqueposition.Thedetentstrengthmaybeadjustedbyreleasingthelocknutonthedetenttube
andincreasingorrelaxingpressureonthedetentspring.Ensurethelocknutistightenedoncethedesireddetentpressurehas
beenset.
Toshifttothe high-speed gear,movetheshiftinghandle upwardfromneutralposition.To shifttothelow-speedgear, move
theshiftinghandledownthroughtheneutraldetenttoitslowestposition.Notethatthehighclutchgearorthelowclutchgear
maynotbeexactlyalignedwhenshifting,sotheoperatormayneedto“bump”themotorcontrolhandleslightlytoturnthemain
clutchgearshaftandshiftingcollarintoalignment.Thisismosteffectivewhenapplyingasmallamountofpressureonthegear
shiftleverinthedirectionyouwanttoshiftthetong,ensuringtheshiftingcollarwill“catch”whenthemainclutchgearaligns
witheitherthehighorlowclutchgear.
