Figure 2 – Correct starting procedure and centri-safety switch
Note: Before starting the engine, you should grip the operator’s handle always. The concrete
finisher is fitted with a centri-safety switch which automatically cuts out power to the engine if
control is lost. If the operator happens to let go or lose control of the handle, the centrifugal force
will cause the switch to move to the OFF position stopping the concrete finisher within one and a
half turns. (Figure 2)
3. The operator of the concrete finisher shall take care that nobody stays or gets into danger area
during operation.
