Phoenix ‘SPC10e’ Self Propelled Metering Chipping Spreader 03/12
1.2.5 Steering Control
The ‘SPC10e’ steers through its front driven axle.
The steering is of fully hydraulic powered type (hydrostatic)
which means the operator will experience little steering
resistance even at extremes of lock and low speed. Further,
there is no feedback so the operator will not sense sudden shock
effects which causes sudden changes in steering angle.
The steering may become stiff and the steering wheel resistant to
turning, if the steering wheel is rotated quickly. In this case you
should slow the rate of turning, if required slowing the
machine’s speed so that the bend may be safely passed. This is
caused by the steering hydraulic ram trying to move more
quickly than the oil flow available. Once you stop steering or
slow the rate of turning, normal operation will immediately
return.
IMPORTANT
Do not steer whilst the machine remains stationary.
This places considerable strain into the steering
components.
There is a hydraulic pressure overload valve within
the steering unit. If steering control is slow or lost
completely, stop immediately and check for obvious
debris jamming the wheels or steering mechanism. Do
not continue until full steering is available.
When the engine is set at 850rpm speed, the speed of
steering reaction is slowed.
For further information on safety cut-out see maintenance
section.
Manual Steering in Emergency
The powered steering will only operate to a very limited extent
when the engine is not running. In an emergency sufficient
manual steering effort can be exerted, in order to bring the
machine to a safe stand still. However, do not attempt to
continue using the machine without the power steering fully
working.
