OPERATIONOFCONTROLS
DIRECTIONALCONTROL LEVER
The directionalcontrol levercontrolsthe
machine’s speed and direction of travel.The
machine hasthree forwardspeeds:second, first,
and third;one reversespeed;aswell asneutral
and park settings.
The speed selection patternisdesigned to allow
the operatortomovethe control leverquickly
between second speed and reverse.The neutral
setting islocated midwaybetween these
positions.Sincereverse and second speed will be
used mostoften for routine sweeping, the area
between these positionsis called the working
range.The directionalcontrol leverpositionsare
labeled nearthe base of the directionalcontrol
leverinthe following order:
PARK:Pull the directionalcontrol levertowardyou
asfarasitwill go.The directionalcontrol lever
should always be inthe PARKposition when
starting,stopping,orleaving the machine
