Operator Presence System - Wacker Neuson RD 12A Operator's Manual

Operation

4.12 Operator Presence System

See Graphic: wc_gr002962
WARNING
The machine is equipped with an "operator presence system". This
system is part of the driver's seat and senses the weight of an operator
in the seat. If the operator is not sitting in the driver's seat, the roller will
NOT drive. If the operator leaves the driver's seat and the forward/
reverse control is not in neutral, the engine will be turned off. When the
operator sits down again, the forward/reverse control must be placed
in the neutral position before the roller can be driven or the vibration
can be started.
Note: A one-half second delay keeps the system from tripping when
the roller passes over a bump.
If the roller is supplied with an adjustable seat, it can be adjusted as
follows:
• Knob (a) for adjusting the seat tension to the driver's weight.
• Lever (b) for adjusting the distance from the seat to the driving
controls.
Note: Do not change position of the driver's seat while the machine is
moving. The "OPERATOR PRESENCE" safety device will prevent all
machine movements if an operator is not seated.
Always wear the seat belt provided when operating the roller.
