All shifts are done manually. "1" (first gear) is the working
gearrange."2" (secondgear) is usedfor driving the machine
on roads and hauling loads for a distance."2" may also be
usedfor working in loosematerial.The transmissionclutches
are designed to absorbany shift changes made.
Down-Shifting
A down-shift from "2" to "1" can be madeat any time. The
machine will decelerate immediately upon the down-shift.
The amount of decelerationfelt will dependupon the speed
the machineis travelingat when the down-shift is made.
Up-Shifting
An up-shift from "1" to "2" can be made at any time.
Acceleration will be the only sensationfelt on an up-shift. It
is not necessaryto up-shift from "1" to "2" when roading
the machine.You may start in "2" range.
The direction lever "N" position has a neutral start switch
incorporated in it. The direction lever must be in "N"
position beforethe enginecan be started.
STEERING
The machine is articulated and steering is accomplishedby
hydraulic power which pivots the main framesat the center
hinge. Turn the steering wheel until reaching the desired
angleof turn. Hydraulic power holds the angleof turn until
the steeringwheel is againturned.
LOADING MECHANISMOPERATION
The hydraulic system provides power for hydraulically
operatedloaderequipment. When the bucket circuit is being
operated,flow to the boom circuit is cut off.
•
NOTE: Holding a control lever in any position except
HOLD or FLOAT for an extended period of time after
the hydraulic cylinder rod has reachedthe limit of its
travel will produce excessiveheat in the hydraulic
systemwhich mayaffect loaderperformance.
